How Many Dimensions Does Our Universe Have?

by Kenny Hoeschen

Cosmologist Andrew Pontzen and particle physicist Tom Whyntie of Head Squeeze take a look at the current theories about the number of dimensions in our universe. The answer is either 4, 5, 10, 11, or 26. String theory and Superstring theory require 26 or 10 dimensions. The folks at the Large Hadron Collider have been conducting tests to try to detect a fifth dimension by colliding protons together, thus creating regions of extremely high energy. So far they haven’t been successful in finding any evidence of one. So, at this time, we know there are four dimensions — at least.
