The Milky Way does not sit still, but is constantly rotating. As such, the arms are moving through space. The sun and the solar system travel with them. The solar system travels at an average speed of 515,000 mph (828,000 km/h).

Spinning fast increases the amount of g forces you feel. After a certain amount you die because your body can’t function properly. Spinning won’t directly cause death, but I suppose if you forced someone to do it 24/7, then after vomiting a lot, they’d die of dehydration.

Four billion years from now, the increase in the Earth’s surface temperature will cause a runaway greenhouse effect, heating the surface enough to melt it. By that point, all life on the Earth will be extinct.

If the Earth stopped spinning suddenly, the atmosphere would still be in motion with the Earth’s original 1100 mile per hour rotation speed at the equator. All of the land masses would be scoured clean of anything not attached to bedrock.

If time would stop, photons wouldn’t move too. As photons would not move and enter into your eyes, you would turn blind. So, you would not be able to see anything. There would be no molecules moving, i.e. wind would stop blowing, water would stop running, you yourself would stop moving, and there would be no heat.

According to relativity, mass can never move through the Universe at light speed. Mass will increase to infinity, and the amount of energy required to move it any faster will also be infinite. But for light itself, which is already moving at light speed… You guessed it, the photons reach zero distance and zero time.
