Scary Simulation
One scary idea that some scientists have is that we might all just be part of a highly sophisticated AI system on a computer somewhere. These individuals believe that nothing in our universe exists – it’s just a simulation. The scary part is that we have absolutely no way of proving if this is true or not!
After all, we’ve created high-tech simulations in science and video games like The Sims. How would we know that we’re not in some video game being played by someone else? If it’s true, I hope that whoever is playing me uses the money to cheat to get me some more cash!
