Why do scientists claim there is no center of the universe?
>big bang
Must have started somewhere.
>universe is expanding
Everything that expands has a center its expanding from. If the universe would start contracting today, It would contract towards the center of the universe.

What is at the center of a galaxy?

How does it have such a gargantuam gravitational power that it keeps billions of stars and other celestial bodies trillions of kilometers away in it's orbit?
