Physicist creates AI algorithm that may prove reality is a simulation
Princeton physicist Hong Qin creates an AI algorithm that can predict planetary orbits. The scientist partially based his work on the hypothesis which believes reality is a simulation. The algorithm is being adapted to predict behavior of plasma and can be used on other natural phenomena. A scientist devised a computer algorithm which may lead to transformative discoveries in energy and whose ver
