I was watching Professor Leonard Susskind's lecture on Quantum Entanglements and he said that there are physicists and people who study physics, who 'rewire' themselves so they can visualize 4 dimensional spacetime in their heads. How can I learn to do this?

1Grab a textbook and solve a lot of special relativity problems, especially the ones that involve graphing. – Zo the Relativist Feb 03 '14 at 19:36

You may want to try learning about Penrose diagrams; these provide a pictorial representation of space-time, and feature its causal structure. – JamalS Mar 25 '14 at 21:35

I read the first paragraph of the PDF recommended by Glen The Udderboat, and didn't understand it. Here's the simple method that I use: drop one of the three space dimensions and replace it with the time dimension. Use the intuitive three-dimensional visualisation that you've used all your life, and swap space dimensions in and out if you really need to consider three spatial dimensions.
