Consider the following thought experiment: Any civilisation advanced enough would eventually create a simulation universe (pictured) if it were possible. Now, since there would be many more simulations (within simulations, etc.) than real universes, it is therefore more likely than not that our universe is artificial.
This scenario has long been put forward by philosophers and pop culture writers. Now some physicists in Bonn are saying they have evidence that it might be true.
In a Paper ‘Constraints on the Universe as a Numerical Simulation’, the research team led by Silas Beane argue that the limits of physical laws in our world mirror what one might expect from a computer simulation.
More can be read about this intriguing idea in the MIT Technology Review.
