Does the cosmos go on forever is an age-old question in philosophy and science the observable universe is finite in that it hasn’t existed forever it extends 46 billion light years in every direction from us but what lies beyond the observable universe.
What we know for certain is that the universe is bigger than we observe it to be essentially because the farthest edges of the universe we can see don’t look like edges at all the observable universe is still huge but of course 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.
The universe is huge but it is only with recent discoveries that we can realize how inconceivably immense the universe or even multiple universes may actually be eternal chaotic inflation which generates multiple universes builds from the theory of cosmic inflation although inflation is generally eternal into the future it is not eternal into the past. New inflation does not produce a perfectly symmetric universe.
