Thanks everyone, I think I need to spend more time understanding the experiments behind it all and their outcomes.

Would someone be kind enough to tell me if I'm getting this correct. Problem A A spherical light source is 1 light year away from Point A at point B. It moves at near light speed in a circumference around Point A to Point C for a distance of 1 light year. When the light reaches it's...

I did send thanks to jtbell, but what prevented resolve for me was being told that the time delay (due to how long it might take light to travel from the object to an observer) is taken into account in Lorentz transformation. By "actually" I mean how fast the molecules in Rock A are traveling...

I accept this, but I guess what I'm looking for, which I'm struggling to find anywhere in clarity, is the reasoning behind these postulates other than that Lorentz's formula never outputs a number greater than 1. I'm trying to understand the reasoning behind the formula. How it is so. Sorry to...

Thanks for your answer. I was aware of Lorentz transformation, but thought it was based on the difference between what one observer might see compared to another and is the result of how long it takes the light from the objects to reach an observer. I know that due to the fixed speed of light...

Blazar jets problem Many thanks for your reply. It somewhat seems to makes sense that you would need an ever increasing amount of energy to explode two objects away from each other as you got them to move close to the speed of light relative to each other. However, what confuses me is that it...

I'm trying to understand the special theory of relativity. All answers I've found to the problem below seem to provide an inadequate answer. Could anyone answer this question? A rock in space at position B explodes into two halves (A & C) in such a (hypothetical) way that each half moves...
