SUMMARY

The discussion centers on the phenomenon of light clocks as observed from different frames of reference, specifically focusing on why a stationary observer perceives the light clock in a moving spaceship to traverse a longer distance. The concept of relativity is emphasized, illustrating that the perceived path of light varies based on the observer's frame of reference. The analogy of a ball bouncing between the floor and ceiling is used to explain this effect, highlighting the distinction between the actual motion and the perceived motion due to relative speeds. Ultimately, the conversation concludes that the differences in perception are rooted in the principles of relativity, where there is no absolute reality, only relative observations.

PREREQUISITES
  • Understanding of Einstein's Theory of Relativity

Why does the stationary observer see the spaceship light clock traverse a longer distance?

How can you prove this? I don't understand why he sees the light take a longer path.

I understand it because you tell me this is so but I don't understand why it actually happens.

Can you understand how a ball boncing between the floor and the ceiling would appear to the stationary observer to traverse a longer path than it would to an observer on the spaceship?
 
I can but that still doesn't really answer the question.

I can actually imagine it both ways. I can imagine looking at the moving observer and seeing his ball bounce directly up and down. I can also imagine it taking the longer path.

Would a ball actually take a longer path in reality?

I want to know why light takes a longer path.
 
Yes, the way you can imagine it both ways are two different ways you can describe the motion of the ball and the light which would be identical to two different Frames of Reference.

there is no 'reality' only 'relativity'
