IMHO it is equally hard to wrap our head around the concept of inifity (has always been there) versus there being a start or end to time and space.
It's a bit weird because if we try to think about the end of space our brain immediately asks "well what is beyond the end?" and so implicitly expects there to be more and more - ad infinitum.
But on the other hand if we think about something being infinite then our brain immediately tells us "hold on! that seems fishy, I've never experienced something infinite, it has to start somehow" and so implicitly expects there to be a limit to everything.
- galaxyLogic 4y agoTo me infinity is the (more) natural circumstance. We are used to just going forward, if there is an obstacle it can be removed somehow. And even if we go around Earth and arrive back to where we started we can then realize: Hey I should be going up instead, not in 3D circles. If then space itself turns out to be curved and round, based on what we have learned so far, we can reason hey there must be some extra dimension (something like "up") which I am missing so far. I must go there to truly experience infinity.
- eis 4y agoOne can argue though that dimensions themselves are a limit. Going around in a circle is infinite in 2D but limited in the third dimension. So one would ask what about the N+1th dimension? Are there infinite dimensions? Maybe infinity is indeed more natural to us since our brain accepts and indeed expects that there is something unknown just to be discovered. But I guess we are coming back to the point of the video/article. There does not seem to be a way to know for sure and we can think and argue about it till the end of time :P
