We live in a three-dimensional reality. Because of that, it’s pretty hard to imagine what a four-dimensional reality might be like, but that isn’t stopping physicists from trying to figure it out. A ...

Theoretical physicists believe math shows the possibilities of a fourth dimension, but there’s no actual evidence—yet. Albert Einstein believed space and time made up a fourth dimension. An example ...
