if you start here and you keep going you end up in the same place. So I could have drawn a circle but this looks more like sciency or science fiction.

So imagine what happens after the big bang. So far I've explained time and infinity and we've explained how there could be a beginning because it's illogical that anything has a beginning because there has to be something before that. But if space and time are in a loop, any kind of a loop, then you don't ever need a beginning because it can just loop. It just is what it is. It just sits there as a loop and needs no beginning. But you might say to yourself where'd this come from? Well maybe it came from a higher level simulation. Because if anybody creates a simulated world that thinks is real eventually that simulated world will also evolve until they can make its own simulation. So in theory the simulations go all the way down. Every simulation will make another simulation to infinity. So there shouldn't be one of these. There should be something closer to an infinite amount of them over time. We don't know if that's happened yet.

Now how do you explain the fact that the big bang was supposed to create a situation where the gravity, because everything has gravity, would eventually slow the expansion of the universe and then it would close back in itself and create the big bang again. That's what the scientists say. But then when they looked at the actual expansion of the universe they found out the expansion was increasing instead of decreasing. The grav
