I saw the following scenario on an episode of Cosmos: An interstellar spaceship accelerates at 1g for the 1st half of a journey to a distant star and then decelerates at 1g for the 2nd half. So with constant acceleration, the velocity would go beyond c at some point, which is not possible. So...
That makes a lot of sense, thanks! I assume that since my ruler is "contracted" from the bystander's point of view, then the ship itself is contracted as well (since either the ship or the ruler could be used to measure the ball's distance).
Hi all, I'm new to these boards. I have a basic conceptual knowledge of physics, but I was just watching some videos about special relativity and the following question struck me. I'm sure this is probably a pretty simple question but it's really been bothering me...
I understand how "c" is...
