Bypass Time Travel problems and become a god
When I was taking a dump at 3am, I've got an idea that makes a lot of sense, but is not explored much. Once we will hit a wall, and discovering new things will take more and more time and effort, and I found a way to bypass it........ If a civilization was able to reach the technological advancment of creating a realistic simulation of a universe, it would be the most powerful creation of everything that is and isn't, because it is the only way to bypass the time travel problem. We can travel to the future by either being near the black hole, or moving at an incredible speed....but If we got there, we cannot return back and there's no way to actually apply the technology from the future in the past because of it.......one way to bypass it, is by creating a realistic simulation of a universe that would be sped up with computational power, meaning that for example a bilion years in the simulated universe would pass in only a few minutes in the real one, and the most powerful way to use it is to simulate it to the point where those simulated civilization surpass you technologically and just use their findings, if we are simulated, it means we are coded and there is a database somewhere, where AI could filter only important things through it, meaning that the fastest way to technologically improve is let simulated universe run faster and copy the technology from the civilizations that are more advancened because they had more time......and this could be done again and again, until there's nothing to know more....
