I am have had quite the issue trying to grasp it, and I know deep down it should not be this difficult. I am very visual oriented. Seems to me that Einstein did it this way to, by visualizing? So what I seem to understand is: I don't get the relationships between stationary (more so non accelerating) observer and an accelerated observer? Both will see themselves as normal but in relation to each others level of acceleration they will see the other as being altered in some way? Is there any simple mathematical equations that will express it correctly. Say like 2 observers - 1 is non acceleration the other is (same direction). what do both of the see from their respects, and what do they see of each other in ierms of time and space. How is that an accelerated object differ? Is only appearance or does spacetime actually distort? I think I had a better handle on before I started learning it, mostly from library material. Sometimes when I model it in my head what they show it works out exactly how I conclude than other times it totally wrong...and it's really stressing me out hehe. Any help would be appreciated, maybe someone was in the same boat once.
