With the advancement of science and technology, using computers, we’ve been able to able to simulate small things. There are games like Flight Simulator, Truck Simulator, City Simulator and what not. Imagine that with new technology being developed every day, we could actually simulate humans or a universe in the long run. The simulation theory put forward by Nick Bostrom suggests that we are actually a part of a digital simulation run by an advanced alien species or by our own future generations. According to Bostrom’s concept, it takes 10 to the power 36calculations to create a lifelike, detailed replica of the entire human history. Now while that may sound like a lot for now, we might be able to perform it in the near future. We could run simulations to find out what went wrong in the past, or to run hypothetical situations such as: If Hitler never rose to power, If the atomic bombs were never been dropped in Hiroshima and Nagasaki cities, etc. So if this theory is true, our world might be one of many simulations that has been simulated by future generations. We might just be tiny computer codes in a computer of the future or a kid’s science fair project. Who knows? What’s even weirder is that those future generations that have been simulating us could also be a part of another simulation and so on.
