These things are confusing as heck. I managed to wrap my brain around the whole, world-lines being in relation to the observer. I managed to wrap my brain around lines of simultaneity. Then I encountered time dilation, and my brain is currently staging a rebellion and refuses to hold a summit unless I agree never to pick up a space-time diagram again.

Anyone know any book or site that can explain space-time diagrams in a relatively painless fashion?
