Physicist Reveals What the Fourth Dimension Looks Like

• 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 from a string theorist gives a view of what a fourth dimension could be.

We move through three dimensions. Or do we? String theorists believe our world encompasses more than three dimensions. Without experiential evidence, the mathematical theory of space and time as a fourth dimension has remained just that since the days of Albert Einstein: a theory.
But in a new video from Big Think, Brian Greene, a string theorist from Columbia University, offers up a relatively simple explanation of just what a fourth dimension could entail—and where it could be.
