Good evening. I just watched a documentary called The Universe-Light Speed. In it, astrophysicist Alexei Filippenko said that galaxies which are very far are moving away from us faster than the speed of light. Also, cosmologist Alan Guth said that during inflation the universe expanded faster than the speed of light. What did they mean exactly? I know that neither matter or energy can break the limit imposed by the speed of light, so I am a little confused.
Thank you in advance.
