10 Most Compelling Pieces Of Evidence That Prove Alternate Realities Are Real

3. Dimensions In Time

Christopher Nolan's Interstellar is the latest in a long line of films that dealt with parallel worlds, but it's also one of the first to actually go about it realistically. Or, y'know, "realistically" - its science isn't totally sound, but it's rooted in some actual hard theory. Specifically (and spoilers for Interstellar, soz), the sequence towards the end of the film when Matthew McConaughey's heroic astronaut Cooper flies through a black hole and enters the fifth dimension, previously thought to be beyond human comprehension. Which is something that actually exists. Well, theoretically, at least. It probably wouldn't look like it does in the film, because it doesn't really look like anything. Our understanding of the universe exists across a 3D vector. In actuality there's a fourth dimension, and humans are only capable of viewing static slices of that 4D system. Beyond that there might also be the fifth dimension, which is really the preserve of mathematicians and physicists, but it's known to exist: that's basically a parallel world, right?
