Is there a limit to the universe?
But if you define it as the limits of the unobservable Universe, the only limit we have is that it’s at least 11,500 billion light-years in size, and it could be even larger. This doesn’t necessarily mean that the Universe is infinite, though.
How can the universe be infinite if it had a beginning?
How can the universe be infinite if it started expanding 13.8 billion years ago? If the universe is infinite, it has always been infinite. At the Big Bang, it was infinitely dense. Since then it has just been getting less dense as space has expanded.
Does the past still exist?
In short, space-time would contain the entire history of reality, with each past, present or future event occupying a clearly determined place in it, from the very beginning and for ever. The past would therefore still exist, just as the future already exists, but somewhere other than where we are now present.
