Give Me 10 Minutes, I'll Give You 5 facts about Stars

Stars are known to be the dominant feature of the universe and are only filled with mysteries and questions. Here are some of the most amazing mysteries about stars that will blow your mind!

1. The star that's there but shouldn't be there.

The star in question is called "SDSS J102915+172927" and like its name the existence of the Star is more complex than you think. This star has been known to exist for 13 billion years and according to theories it shouldn't even exist as the universe itself is known to be 13.8 billion years old. 13 billion years ago there was just gas and debris in space so its difficult to wrap our head around the existence of a star. Since the star did exist during the time this would also mean that the earliest planets revolved around this very star.  


2. Not all stars are hot

3d representation of a cold star from a planet 
NASA has found 14 stars that have extremely low temperatures. These stars are known as failed stars because well they could not develop after the Big bang. Their low density prevents these stars from fusing atoms within their cores. The heat generated from every star directly depends upon the rate of fusion occurring at its core. Since this doesn't take place on these cold stars, no heat is generated. Finding such a star is extremely rare and can only be seen in spectrums beyond the human eye i.e. Ultraviolet or Infrared. So the next time when somebody says that all stars are hot you can use this to counter their argument.

3. Stars formed from Stars

According to theorists before the big bang there existed a similar universe like ours. This universe had seen its end and had collapsed into one big star. What happened after this led to the big bang. So you could say that the stars we see today are the creation of the stars that were there in another universe before the big bang. 





4. Blackholes form from stars

We know that a collapsed star forms a black hole but what exactly happens. When a star collapses it has basically lost all its energy and it throws its energy into space. Accept sometimes there exists a gravity on this dead star that has the tendency to pull back this energy of the now dead sun. Most of the time this energy wraps around the dead star to form a spiral but if the energy falls back on the neutron star, a black hole is formed. The sun gets destroyed because of its own energy. This is known as the fall back. Its like throwing an object towards the sky on Earth and it comes back down. 

5. Stars in the sky aren't where they are seen
If the star was moving away it would only be visible in
Infrared. Otherwise it is visible in the Ultraviolet spectrum.

Space is expanding faster than the speed of light and it is causing Stars and everything in the universe to move. This means that stars are continuously moving in Space and what stars you see now are just the light that remains of the Star. The star itself has moved ahead. So what you see today might have been the position of the stars a few million years ago. Yes you read it "MILLION"!




Stars are everywhere in the Universe. Humans have only looked at a handful of stars in the universe but the amount of information from these stars has been ground breaking.

What Will Space Be Like In a 100 Years?

Space is ever changing and its fascinating to think about what space would be like a 100 years from today. Here are some facts:


1. The Andromeda galaxy

The Andromeda galaxy will be the biggest change in the skies when viewed from Earth. Currently at 2.5 million light years from the milky way, the Galaxy is known to be moving towards the milky way.  A hundred years from today, the galaxy will be much more prominent in the sky. The collision between the galaxies will occur a few billion years from today and should not affect the position of the Earth allowing human existence to continue. The galaxy is known to be twice the size of the milky way. The image shows you a future representation of what the galaxy might look like from the Earth a hundred years from today. Unfortunately for now the galaxy is only visible as a diffused cloud and we can only see it side making it difficult to spot in the Sky.

2. The Sun

Long term secular change in sunspot number is thought by some scientists to be correlated with long term change in solar irradiance. For example in the 17th century, scientists observed a pause in the solar cycles of the sun and this had a drastic effect on Earth also known as the little Ice age experienced by Europe. It is known that these changes take place every 41,000-100,000 years and are considered to be a valid reason for the Pleistocene Ice age that began 1.8 million years ago and ended 11,700 years ago. apart from this the Sun will act like any other star and expand once the Hydrogen fusion in its core has stopped. According to scientists, the sun has remained stable for 4 billion years and will remain stable for 4 billion more years. So a hundred years from today the sun might not become a monster but it will get hotter as it is getting hotter every second due to the Hydrogen fusion. 

3. Pluto


A hundred years from today Pluto would have reached its furthest point from the sun. Today Pluto is known to have barely started its journey away from the Sun. It takes Pluto 248 years to go around the sun which means after a hundred years it should have reached approximately near the furthest point from the Sun in its orbit. As Pluto moves away from the Sun it will have the tendency to lose its atmosphere due to extremely chilly temperatures. The atmosphere will collapse into the planet. This kind of climate change has never been observed in any other planet of the solar system. Scientists have found out that thanks to the Earth's rotation rate, the speed of the suns rotation is reducing by 0.00003 seconds per year. This is affecting the angular momentum of the Sun causing the Earth to move away from our Star. So its safe to assume that every planet is having the same affect on the Sun. So maybe a hundred years from today the solar system might have 8 visible planets with Pluto flying into interstellar Space.

4. Humans in Space

Humans will be able to get a pretty good experience of Space a hundred years from now. With companies already running contests for people to go to Space, it won't be long before Space travel will be like air travel today. Mars and the moon might act as second colonies in a hundred years allowing people to live on these planets and spend their holidays. It seems unreal but everything that we have today seemed unreal a hundred years back so the possibilities are endless.

5. More Earth like planets

We might possibly look for colonisation of different worlds as Earth doesn't look like its going to stay for a very long time. In a hundred years, we should be able to start the large colonisation movement and send life to other planets increasing the existence of the Human race. Currently NASA uses the International Space Station to conduct experiments for these purposes. The milky way is alone estimated to have over 2 billion Earth like planets. The only problem is the distance which makes it impossible to reach these planets within the human life span. Maybe travelling faster than light might become a possibility a hundred years from now.

These were some facts about Space a hundred years from now. As incredible as it seems most of us won't be there to experience it first hand. Anyway we should feel lucky enough to already know what it would be like a hundred years from today.

What if a satellite went around the Earth in the opposite direction?

The animation shows retrograde and prograde rotation of celestial objects in Space.

The Earth is known to spin in the counter-clockwise direction when viewed from the top. It is known to spin at 1670 Km/hr which is extremely fast considering the size of the planet. From Earth, satellites are traditionally sent to space to rotate in the direction of the earth's rotation. This is normally done because of the speed advantage that the Earth provides to the satellite adding 1670 Km/hr to the speed of the satellites rotation this is known as a prograde orbit. Rotation in the opposite direction is known as retrograde orbits.

Why there isn't any gravity in Space?



The notion that there is no gravity in Space is wrong.

Is our sun also moving like planets?


For as far as we can see, the Sun is in a centrally steady position with the planets revolving around it. But if you zoom out a little bit and look at the Milky Way, your perspective changes drastically. The Milky Way has a centre that is supposedly a collapsed star also known as a black hole. A strong centre around which many celestial bodies revolving is in a way the rule of the universe. If this is true, it means that our sun is moving continuously and taking the entire solar system with it. But if this were true, why hasn't there been a collision in all this movement?

We have to consider that if the Sun revolves around the milky way then everything else in the milky way is also doing the same thing. There could also be the possibility that our sun and the solar system might be revolving around a bigger sun which makes our existence really small in the sea of the universe. The possibility of this maybe unlikely because if it were happening, we would be able to see two suns in our sky.

Looking at an even bigger picture, if the sun revolves around the Milky Way then is the milky way also doing the same thing but at a much much larger scale that we are not able to perceive. If this were happening then this could be the way the universe works. The galaxies look stable but in reality they are moving around this huge central power. This would also prove that how are Galaxies stationary and not moving around. We will be able to conclude that there is no such thing as dark matter.

The star positions appear similar to us every night because everything in the milky way must be revolving around the centre at the same speed. A better example of what's happening here can be two trains travelling at the same speed parallel to each other. The people on the two trains will feel that they are stationary but in reality they are moving at very high speeds.

What's the ISS docking procedure?


The international space station or ISS has been up in Space for more than a decade and it has seen many people aboard it. Astronauts mostly go up there in shifts of 6 months but there is a lot of procedures and physics involved in the transportation of these astronauts.

Astronauts first board a Soyus rocket in Russia that takes them up into space. Since the ISS is moving around the Earth at 17,000 Km/hr its impossible for the launched soyuz module to straight away reach the ISS and dock. There are several burns that astronauts have to perform during the procedure.

The first step is to get the soyuz module to start orbitting the Earth. For orbitting the Earth the astronauts use up one of their several burns. The next step is to move towards the ISS. Now the astronauts have to perform burns at each half orbit points. So a burn at 180 degrees of the orbit and another burn at 360 degrees. This will allow the circumfrance of the Soyuz's orbit to increases allowing it to get closer to the ISS. 

Finally when the Soyuz rocket is inline with the ISS the astronauts apply another burn that allows the Soyuz rocket to get ahead of the ISS. Now the soyuz rocket is supposed to rotate so that the hatch faces the dock of the ISS. A final burn procedure is performed to get the Soyuz closer to the ISS and ultimately the module is docked.

It typically takes around 30-35 minutes for the entire docking procedure and the soyuz is continuously monitored from the ground to ensure that the angles are correct. A slight micalculation can be disastrous.          

Later this month Scott Kelly and two other astronauts will be travelling to the Space station which is what made me write this post cause surely people might want to know whats happening through the journey from Earth to ISS.

How Jupiter could have destroyed our solar system?


Jupiter, the worlds largest planet in our solar system, known for its unpresidented gravitational force wasn't as dosile as the planet is today. Jupiter during the inception of the solar system wasa violent beast calling for destruction. Jupiter had a powerful whirling spiral that was the product of the large gravitational force the planet posseses. This whirling spiral was known to suck and throw objects into Space and towards other planets. It might have been a very scary site from Earth but to be fair human civilization didn't exist during the time.

According to Scientists, the only thing that saved the entire solar System was the planet Saturn. Saturn was known to also posses a very strong gravitational force that maybe was even more powerful that the gravity on Jupiter. This gravitational fource from Saturn helped Jupiter to get rid of that devestating whirlwind spiral. The forces of saturn also caused Jupiter to be placed behind mars in our Solar System.

Jupiter's gravitational force has never reduced as even today anything coming even remotely close to the planet is sucked in by it. The gravitational forces have also caused continuous sandstorms and the infamous red dot on the planet is actually a sand storm that has existed for centuries. Apart from this the planet has also been known for changing the course of many flying objects and also caused the formation of many other celestial bodies. Now thats a lot of creation and or destruction from one planet. 

Saturn on the other hand might have lost some of its gravitational force as it isn't as powerful as before. But it still is able to hold its rings and moons which makes it the most beautiful planet in our solar system. Its fascinating to think about the history of these planets and the kind of activities our solar system has gone through.

Why string theory doesn't add up?



String theory suggests that the point-like particels in particle physics are represented as one dimensional strings. Now there is a model of the universe that is built on string theory which is what doesn't add up for me. This model shows space as a blanket of strings on which everything in the universe sits.

The revolution of the Earth around the Sun and the moon around the Earth make sense in this model. But what about objects that are in continuous motion and aren't revolving around any object like asteroids. If space were a blanket of stirngs, that would mean that there should be a sense of direction as well in Space. But that just isn't there. There probably is a criss cross of blankets in space. This only complicates things instead of simplifying it. Since string theory is supposed to represent everything in one dimension, Space just cannot be understood with this theory.

Finally these are just theories and haven't been prooven. Actually it isn't possible to proove such theories because they have just been made up to make it easier for the understanding of the universe. Using string theory for the secrets of the universe isn't going to give you too many ground breaking answers.

Why are all planets round?



There was the medieval times when people believed the earth to be flat but now that we know our planet is round, a quetion rises in my mind. We see our eintire solar system and all the planets are round. There isnt a single square or flat planet. Even our sun is round which is why I was wondering why everything is round?

According to scientists, the shape was just ment to be. Durng the big bang, all the debris floating around Space came together to form round planets. I believe the shape of our planets is the way it is because of the shape of a higher power. The Sun is also round and I believe thats what caused the shapes of all the planets to be round. Thats why the debris from the big bang went around the sun. If the Sun were square there wouldnt have been the possibility of something orbiting the star.

When planets were forming and there was constant collision of debris, it was causing these new cellestial objects to revolve on their own axis. This also is a reason for the spherical or round shape of the planets. The debris were mended to take a circular shape due to the forces acting on them during the revolution. Another reason could be that it is the easiest of all geometrical shapes to just form on its own.

What would happen if the Earth looses its lone natural Satellite?



The moon believe it or not has a huge impact on many natural phenomena that we just don't realise. Its hard to believe that something as far as 384,000 Km has some sort of impact on the everyday routine of Earth. But astronomers have proven that the moon is actually moving away from us and in a few hundred thousand years, the moon will fly out of its orbit and the Earth will become lonely. What would be the affects of this?

Loosing the moon will cause the Earth to lose its access. Apparently the tilt in the Earth's access is due to the moon and the Earth's magnetic nature. If the moon were to move away, the Earth might topple over and change its access regularly. So you might be at the northern hemisphere one day and the next day you might see your self in the southern hemisphere. A very good example is Uranus. Though it isn't formally known why Uranus rotates at a tilted axis of 98 degrees, the loss of moons could be a reason.

The moon controls the tides on the Earth. This is a pretty well known fact. So no moon means no waves. The surfers might get pissed. The water on the Earth may remain stagnant. Though earthquakes are another source of waves, it doesn't happen as regularly. Another sad fact would the the sky would look boring.

What would happen to the moon if it looses the Earth's support? I believe it might just end up somewhere near Jupiter if it goes in that direction. Most probably it will be on a collision course with maybe a planet.

Is there anything beyond Space?



Space according to theorists is ever expanding and is moving faster than the speed of light. Thats why we cannot perceive or see Space moving. If Space were expanding then it should be within something that holds it altogether. What might we see if we would be able to overtake the fast moving ever expanding Space?

Many scientists would classify travelling faster than light as preposterous since the great Einstein says its impossible to travel faster than light. But it hasn't stopped Scientists from speculating. Theories suggest that if somebody were to travel faster than light, they would be traveling back in time. Sounds amazing but what would you see?

You would see all of Space again and again. Actually you would be seeing what Space looked like during particular time instances. So at the end you would reach the time before the big bang. Since we believe the big bang was the source of our universe and everything we see thats as far as we might  be able to go.

As we humans can only perceive three dimensions we aren't able to see whats beyond Space. There are more dimensions than what we can perceive and the answers to whats beyond Space lies in the perception of dimensions. Maybe in the future humans might have advanced to such a great extent that time travel might become a reality. This is the time when humans will be able to see Space and the world like we cannot even imagine.

I believe everything in the universe is held within something. So Space has to be within something or some force that holds it together. That something might also be within something which will also be within something......... ah you get the point!

Will humans live to witness the death of the solar system?

An exploding star. Probably the suns explosion might look something like this.

21st December 2012 is long gone and we are still here. We thought the apocalypse was certain on this day because the Mayan's were too lazy to write more calendar years.

We know that in a few billion years the Sun will start expanding eating up anything in its way including Earth. After this the sun will explode and the remains of the explosion will be a small star around which Mars and the other remaining planets will circle around. But will there still be humans?

We humans are doing things that will lead to our extinction long before the Earth is in any trouble. Humans will be the sole reason for getting the human race extinct long before all the other natural events occur.

Innovation and discoveries are the answer for extending the life of the human race. Green house like
structures that will mimic the atmosphere of the Earth could be an answer to the survival of all forms of life. The natural atmosphere will be long gone in a few hundred years. Another answer is migrating to another planet and Mars seems to be the planet where there are elements of life and it isn't too far away.

I believe that humans will still be present to experience the death of our Solar system and continue to live even after the solar system is finished. Technology would be so advanced during the time that there maybe no force of nature that could cause human death.

From where did Earth get its water?



Its a question that is so incredibly simple but has a very interesting answer. The water found in Space came from a Solar nebula that gave the Hydrogen. Collapsing stars during the early stages of the universe formed Oxygen and the result was water. There are two theories for water on Earth.

One theory suggests that water came from the many asteroids that impacted the Earth. An asteroid contains 80% water so this could be a reliable theory. Another theory suggests that Earth got water from the above solar nebula. Water travelled through Space interacting with the different forces before finally reaching the Earth and clinging on because of the Earth's gravity.

 Astronomers are still not 100% sure as to where the water truly originated from. The second theory seems to make more sense because the Earth is mainly made of 70% water. Such a lot of water cannot be the result of just asteroids impacting the Earth. Both events happening at the same time makes more sense. The asteroids created craters that could hold the water from the Solar Nebula.

I in-fact have one more theory. Since the Earth is made of mainly Carbon, Oxygen, Helium and
Hydrogen, I believe the asteroids merely left elements that later combined on their own on Earth to form water.

Another fun fact is that there is a large H2O cloud in Space that contains 120 trillion times the amount of water on Earth. The cloud is known to circle a black hole which is known to emit energy in the form of light and electricity.

Why does the sun produce solar flares?



The Sun is pretty hot and occasionally we see bursts of flames on its surface. This discharge of radiation is known as a solar flare and it is quite common. These solar flares are known to travel through our entire solar system causing drastic effects. Luckily the Earth is not affected due to its magnetic nature that causes the solar flares to deflect away and move towards other planets.

Most people may consider the Sun to be a hot ball of fire. While its technically true but science gives a much better explanation of how the Sun is so hot. The sun is mostly made of protons. When two protons are on a collision course they usually repel. But the speed at which the protons travel in the Sun is so high that eventually protons crash into other protons and combine with each other. This collision generates energy in the form of heat. This is why the sun is so hot. It is a ball of energy formed by colliding atoms. 

Sometimes an excess amount of energy is generated on the surface of the Sun. This is where Solar flares come into picture. They are the excess energy generated from the collisions of protons. This energy is released because it is more than what the Sun can handle. You can also call it as excess energy the sun is producing in the form of heat. 

And as always...............

Was there ever life on Mars?


The red planet as it is called, Mars sits just at the edge of the habitable zone in our Solar system. NASA's curiosity rover has found traces of water on the red planet. Speculations suggest that there once was a time when there were seas or rivers on the red planet and that the planet was exactly like Earth. Which further gives us a clue that maybe humans to existed on the planet.

Ancient paintings on caves have shown people flying into space. It shocks us that if people could draw something like that on caves it suggests that the technology did exist during the time and it was used repeatedly. Some experts suggest that human life began on Mars. When the planet became barren the human race left it and settled on Earth. If this were true, the technology that existed such a long time ago is way ahead of what we have today.

Could Mars have been a part of Earth?

The earth was much bigger than what it is today. There was a collision which caused the Earth to loose a lot of mass. This formed the moon. Some say the moon actually collided with the Earth and thats what caused the tilt on its axis. Anyway what I believe is that the collision caused a lot of debris to fall into space. The debris must have come together to form the red planet or at least part of what the red planet is today. The rest of it might have come from other planets like Jupiter or the asteroid belt. Why did I come to this conclusion? Maybe because the planet is around half the size of Earth.

It is very much possible that there was life at Mars as there have been traces of water. But if my conclusion were true, the water found at Mars was just a part of Earth a long time ago which means that Mars was always the red planet with similar conditions that exist on the planet today.

The question came to my mind when I was reading about the findings of NASA. The comments section is open for your opinions. And as always...........

Did we actually go to the moon?



Conspiracy theories about the 1969 Lunar mission carrying Neil Armstrong and Buzz Aldrin to the moon are still strong. According to recent data, 20% Americans like to believe that the above mission was just a photo studio. I like to be on the 80% side that says that we did in fact go to the moon in 1969.

The photograph at the start of this article has raised many questions about the credibility of the 1969 mission. The following are the questions raised looking at the above image that even come to my mind:

1) Where are the stars in the background?

Now This question is by far the fuel behind the conspiracy of the moon landing. There have to be stars in Space right. So how is it not visible? NASA scientists say that the Sunlight hitting the moon surface was so bright that it washed out the light from the stars causing it to not show up in photographs. Obviously people will look at this photograph and feel that this could be a set because of the missing stars making the background look like a black backdrop.


2) In the video footage the flag seemed to be moving and stay upright. How would it be possible for the flag to stay upright and move if there were no air on the moon?

The flag has a pole on the top end across the length of the flag. That pole is what is keeping the flag upright. As for the movement, when the astronauts placed the flag in the lunar surface they forced it into the lunar surface with a forward and backward motion. This caused the flag to move and keep moving for some time even after the astronauts left the flags. 

My opinion is that 1969 was the year when NASA put 2 men on the lunar surface and it truly was "One giant leap for mankind",

The question came to my mind while looking for a documentary of the 1969 moon mission. When you google search the mission the conspiracies also show up. The comments section is open for your opinions. And as always........

Is gravity there everywhere in Space?



The earth has a gravitational force of 9.8m/s and it is acting on you constantly. It doesn't affect you in a way that you would notice since we are used to it. In outer space there isn't any gravity according to most humans but science has a different opinion. Science or particularly Physics talks about dark matter and how much we don't know about it.

Dark matter is the darkness that we see in Space but cannot perceive it. According to scientists, the amount of objects or celestial bodies visible to us accounts for only 5% of the total area of Space. The rest is covered with undiscovered darkness. If the darkness in space were nothing, stars and galaxies would be flung around and our solar system wouldn't have lasted for even a few minutes. But since its been 13 billion years, there has to be something holding everything in place.

That something is "Gravity". This gravity may not be the same 9.8 m/s but it is definitely there that is holding all the galaxies and stars in place. Sure all celestial bodies change position slightly but if there were no force, these bodies would be flying around.

Newton's first law says that objects in motion must continue to be in motion unless an external force is applied to it. This external force in the universe is gravity in the form of space. There is another theory that suggests that everything in Space is falling. We don't see it or feel it because nothing is stationary in Space.

This question came to my mind when I was looking at newton's first law. Also a space documentary got me thinking in this direction. The comments section is open for your opinion.

What color is space?


You might think that the answer is black but I have something more to add to that answer. I definitely feel that Space is beyond 3 dimensional perception. We can see Space as an endless area of black but it does not have a proper explanation.

The prism experiment
We all have seen the prism experiment where the suns rays are allowed to fall on a prism at an angle and we see a band of seven colors on the other side. But scientists have found that these are the colors that only we can perceive. There are colors beyond violet that we call ultraviolet and red that we call infrared. These colors can only be sensed by temperature according to us. Space might be extremely colourful but we just cannot perceive it. Maybe its a color that some other organisms can see. 

According to physics we obtain the color black when there is no source of light. White is obtained from the mixture of the 7 colors that we see in the prism experiment. Doesn't the definition of the color black seem a bit incomplete. When there is nothing, black color is obtained seems just wrong. I believe there must be something that forms the color black.

This question popped up in my mind when I was studying about the spectrum fundamentals in physics. It was a long time ago but the question still remained.  The comments are open for your opinions. And as always.............

What is a black hole?

An artists representation of matter swinging around a black hole. (Image from: nasa.gov)


Space is infinite and beyond what we humans can currently explain. Black holes certainly fall into the category of being unexplainable for now.

I watched Michio Kaku's universe in a nut shell and then I went to see Interstellar (An epic film BTW). Everything was going ok until we reached the last half an hour of the film where Matthew Mcconaughey (Cooper) has suddenly decided to go inside a black hole. Thats when I was puzzled. Off course we know what happened next. I also know that films are just fiction but the question suddenly popped in my mind. Can we actually go inside a black hole?

Accordingly to what scientists have found out about black holes the answer is no you cannot travel inside a black hole and live to tell the tale. To give a short explanation, a black hole is a collapsed star. The only difference between a star and a black hole is that heat isn't emitted as much from a black hole. At the same time the gravitational pull of a black hole is much larger than a star. Stars can be centres of solar systems but black holes are often the centres of Galaxies.

Einstein might go crazy if someone could actually go into a black hole, reach another universe and come back to tell the tale. E=mc^2 or the theory of relativity clearly suggests that nothing can travel faster than light. If you were to reach near a black hole, the experience would be as follows. Since the  the black hole is huge after a point you would only see darkness without experiencing any movement. Your body would stretch out until it was ripped.

There is no way for now to travel into a black hole and reach the singularity (centre of the black hole). Let alone using it as a portal to travel through the universe. As always the comments section is open for your opinions on the topic.

Why are stars dissapearing from the sky?

When I was 6 or 7 years old, I distinctly remember seeing many stars in the sky but never gave it a second look as I thought it would always be there. Looking up at the sky today I see nothing. At first it was disappointing but it got me thinking. Where did the stars go?

And so like every human being in this planet, curiosity drove me to google and made me type the tittle of this blog. What google told me was a whole lot of Science which was interesting but is there more to what I read? The "Light pollution" in larger cities is a factor to be considered and it might be also true. Another explanation said that if our eyes are present in darkness for a long period of time, they get used to the darkness allowing us to view a lot more stars than before barring that there is no light pollution. So these are the genuine explanations that are all correct but let us look into the future of what could be more causes of stars disappearing?

Space (the entity if you could call it) is expanding. The speed of this expansion is constantly increasing. Space around the Earth is also continuously expanding. Doesn't this mean that emptiness is coming in between the stars in the universe and our planet? So in the future this could also be an added explanation as to why the stars are disappearing from the sky because the stars would have literally disappeared. The comments section is open for your opinions on the subject.
