And while more exotic ways to travel around the universe are scientifically possible – wormholes, for example – we don’t know how to make them, the universe doesn’t seem to make them naturally, and there is no reason to think they’d connect us to Another-Earth rather than some random part of empty space. Strange needs to use magic for this.Īccording to Albert Einstein, we can’t travel through space faster than light. The fiction of the Marvel multiverse stems from the ability to travel between these other earths. With enough space and enough planets, any possibility becomes likely. If there is more space out there, full of galaxies, stars, and planets, then there are more and more chances for Another-Earth to exist. We can see billions of light years into space, but we don’t know how much more space is out there, beyond what we can see. So, which of these ideas has Marvel based on science, and which ones are just pure fiction?Ĭould there be other Earths? Could there be other people out there, who look a lot like us, on a planet that looks like ours? Scientifically, it’s possible, because we don’t know how big our universe actually is. In Doctor Strange in the Multiverse of Madness (in cinemas now), the universe-on-universe buffoonery threatens a “desecration of reality.”
