Relativity is how things have significance to you in relation to what you know or how you think. Relativity goes way beyond physics and is a big factor in Magic. Everything you know and understand is all relative.This physical world is not the same for everyone.How you have been brought up, where you live, and your beliefs are all relative.You only know things compared to other things.You can not know things without being intimately involved.When you were a kid you did not know the difference between hot and cold or big and small?You had to experience it.Everything is relative.
