Not to nit-pick, cause it's a very enlightening video to those who didnt master it the hard way ;-p
but what has this got to do with QED?

Quantum electrodynamics - Wikipedia, the free encyclopedia

QED deals with how matter and light interact. And explains how the electromagnetic, weak and strong forces are all aspects of the same force, it says nothing about dimentionallity (at least of space-time)
