Will Our Universe End In A Singularity?
The sun will eventually run out of its fuel and become a red giant and in the process consume our planet Earth. In the final burst of its glory our beloved sun will expand and engulf the closest planets and then explode into a planetary nebula leaving behind a dense white core which is known as a white dwarf. We know that in 4.5 Billion years our galaxy will collide with our neighbouring galaxy The Andromeda Galaxy. But the End of our universe is something very hard to predict, because we still don’t know much about how it started and the physics behind that. Seeing the current expansion of the universe and the unknown forces behind it we can try to predict some possible fates about our universe.
And if this expansion stops, what’s going to happen next? What if all the galaxies, stars, planets – everything – stopped moving away from everything else? Would the Universe as it is just freeze? Or would it collapse into a single point, just like it was before the Big Bang? In this video we are going to talk about, What if the Universe stops expanding?
