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.

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.

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...............
