Question

From simple, visible observations (without the use of high-tech, modern technology) how do we know the Sun is rotating? What if the Sun stopped rotating? What about the Sun would be different; if anything at all? Is it important to our lives here on Earth or the future of the solar system that the Sun does continue to rotate? For this last set of questions, do not just answer an opinion here...actually do some research (internet if you wish) and describe at least ONE thing that would result if our Sun stopped rotating

Answer 1

Answer: Yes the sun certainly does rotate or spins faster at its equator than its poles. The rotational period of the sun is about 24days at its equator and 35 days at its poles due to the composition of the Sun which is a liquid not solid. This discovery has been done through the observation of the motion of the sunspots.

If the sun stops rotating, all the planet in our solar system comes close together and would be collapsed. The rotation of Earth would be ceased due to which ocean would be ripped off from their surfaces, nothing on the earth can stay due to wind flow which causes hurricanes with much more strength. The massive earthquake, worldwide volcanic activity can take place due to the stress of the earth's crust. There's no fiction at all. It would be the end of the earth and our solar system.

The Sun is about 4.5 billion years old. Since its birth, it has used up about half of the hydrogen in its core. It will continue to radiate “peacefully” for another 5 billion years or so. But eventually, it will run out of hydrogen fuel. It will then be forced into radical changes which, will result in the total destruction of the Earth and also our solar system.
