Universe

The more I thought about time, space and universe, the more fascinated I became by what I have learned from Jorge Cham and Daniel Whiteson. They wrote a witty and entertaining book Frequently Asked Questions about the Universe. 

Will time ever stop? Why can’t we teleport? Do we live in a computer simulation? 

Yes, I know, that might seem like an outrageous question. Then again, maybe it doesn’t. 

As we can see, simulation is no joke. People start to imagine a future in which everyone is running a simulation of a universe in their home computers. The idea that the world isn’t real and that there could be simulated people inside of them running more simulations might be technically feasible. That’s a simulation inside a simulation. Why not? The more simulations being run, statistically speaking, the more likely that the so-called universe is a big video game. 

We don’t currently know whether the world we live in is real, and we might never know.
