Question

Is the universe infinite and expanding or it is a finite and had its own limit.​

Answer 1

Answer:

First, it's still possible the universe is finite. ... The observable universe is still huge, but it has limits. That's because we know the universe isn't infinitely old — we know the Big Bang occurred some 13.8 billion years ago. That means that light has had “only” 13.8 billion years to travel.
