Sean Carroll, Roger Penrose, Carlo Rovelli, Adrian Moore and others on the plausibility that the universe may be eternal and and therefore, actual infinities may exist.

Do you think the universe can be eternal? This, I think, brings many aporias.

If the past is infinite (rather uninitiated), we can go infinitely backwards, right? But if the past is infinite, it would take an infinity of time to elapse (the past), wouldn't it? But an infinite time would never end, precisely because it is infinite. However, the past has already end because we are, obviously, in the present. So, how can the universe be eternal?
