Description

I look at the galaxies that are moving away from us faster than light because of expanding space. Check out this video's sponsor https://brilliant.org/dos

Ninety seven percent of the galaxies in the observable universe are moving away from us faster than the speed of light. You might wonder how this can be true when one of the unbreakable laws of the universe is that nothing can travel faster than light. But this only applies to things moving through space and these distant galaxies are getting further away from us because the space between us is expanding. So the distance between us and them is increasing faster than light could travel across that space. This is also why the observable Universe is 45 billion light years across despite only being 13.8 billion years old.
