There's a 20% chance we're living in the Matrix, says researcher

This is older and backdated, but I wanted to make sure I get this on here for future reference. Fascinating take on a deep philosophical problem.

Until I talked to Nick Bostrom, a philosopher at Oxford University, it never occurred to me that our universe might be somebody else’s hobby. I hadn’t imagined that the omniscient, omnipotent creator of the heavens and earth could be an advanced version of a guy who spends his weekends building model railroads or overseeing video-game worlds like the Sims.

But now it seems quite possible. In fact, if you accept a pretty reasonable assumption of Dr. Bostrom’s, it is almost a mathematical certainty that we are living in someone else’s computer simulation.

I think it's quite likely that this universe is just an illusion. Even matter is mostly empty space. It seems like a projection, or a Matrix.
