If the big bang happened 13.8 billion years ago, and the universe is 93 billion light years in diameter, how did the universe expand faster than light?
In: Physics
Follow up question though, the diameter of the known universe is based on how far we can observe. If the universe is expanding faster than C, then how come we can observe light from 93 billion light years away?
Wouldn’t it be more logical to assume that the universe expands slower than C so light can still reach us albeit at a much longer amount of time? Just like walking up an escalator that is going down. If you walk faster than the escalator going down, you will still reach the top but at a much longer amount of time.
Sorry if this is stupid
