As our current video games become more and more lifelike and realistic, it's becoming clear that at some point, perhaps soon, our simulations will be indistinguishable from reality. If that's true, how do we know it didn't already happen? Could we be in a simulation now? A simulation created by someone?

Moderator Neil deGrasse Tyson, director of the museum’s Hayden Planetarium, put the odds at 50-50 that our entire existence is just a program on someone else’s hard drive.

“I think the likelihood may be very high,” he said. He noted the obvious gap between human and chimpanzee intelligence, despite that the fact that we share more than 98 percent of our DNA. Somewhere out there could be a being whose intelligence is that much greater than our own. “We would be drooling, blithering idiots in their presence,” he said. “If that’s the case, it is easy for me to imagine that everything in our lives is just a creation of some other entity for their entertainment.”

This is really a great theory. Learn more about this in the videos below:
