The question that everyone has been dying to know has been answered. Finally! What will scientists study next?
Infinite time is undefined though. We are not sure there was time before the Big Bang. Before anyone says “but there must have been,” consider that it’s just as paradoxical and mind blowing to imagine that time never had a beginning and just stretches infinitely into the past. How can that be so? It means it would have taken an infinite amount of time for us to reach this moment in time, and that means we never would have.
Infinite time is perfectly defined, it just doesn’t exist in our universe
Why must the concept of time before the big bang (or after our heat death) exist in our physical reality for us to speculate about theoretical infinities past those? The thought experiment is about infinite time, not all the time in our limited universe. A lot of things happen at infinity that break down as soon as you add a limit, but we’re not talking limits when we’re talking infinity.
I think the implications behind there being infinite time in the past are fun if you assume that the universe works like a stochastic state machine. It means that either every finite event that has happened and will happen has already happened an infinite number of times or the universe is infinitely large.
