The material world we live in is somewhat complicated when we analyze it at a sub atomic level, how the tiny particles interact with each other and how it affects and transforms our surroundings. Physicists come up with some of crazy new theories every now and then about how the universe works. Some propose the idea that everything, in an absolute sense i.e: Time, gravity, particles, waves, etc is all made up of data and code, therefore, making the universe one big computer software and perhaps a virtual simulation for another supreme civilization to conduct research. But there are even crazier and complicated ideas of how the universe works! Recently, according to a study, the world we perceive is just an illusion and doesn't exist, that is until we actually look at it. This illusion is, however, closely viewed at a quantum level.
