Einstein’s general theory of relativity suggests that our universe is finite but lacking a boundary or outer edge. Huh ? No comment..lol

As long as there was a beginning to the universe, there will be an edge. If the universe is 14.5 billion years old, the universe cannot exceed 14.5 billion light-years in distance.

@U53RN4M3 13.8 billion years*

@U53RN4M3 You would think that, but a popular physicist says it larger

@usher As the other guy suggests, maybe it's expanding faster than the speed of light. That's the only way I can think of. If that's the case, Einstein was... wrong!

@U53RN4M3 This might help, not sure[youtube=https://www.youtube.com/watch?v=vIJTwYOZrGU]

@U53RN4M3 Not really, the expansion of the universe changes that.

@Alison Which comment are you referring to?

Alison · 18-21, F

@U53RN4M3 Oh your opener. The visible universe has a diameter of 93 billion light years. Coz its been expanding and some the light has moved over the expansion to us.

U53RN4M3 · 36-40, M

@Alison So the speed at which the universe is expanding is increasing, perhaps exponentially? I think this is where dark energy comes into the discussion, right?

@U53RN4M3 I never got that far *laughs*, this stuff b hard to get your head around *laughs*.
