Hello everyone! I'm new to the group and have an interest in General Physics, GR, SR, and the study of Light. I've been away from the academic area for a long time (worked in engineering and management for many years). I am now retired but enjoy 'exercising my mind' and interacting with those that really want to better understand the universe around us.

Welcome to PhysicsForums! Great to have you here. :smile:
 
Looks like your first question thread is getting great replies :wink:

Summary:: Michelson Morley experiment - flawed experiment??

I've heard claims the Michelson Morley experiment proves light moves at the same speed in all reference frames. However, after looking through the experimental setup, I do not see how they can make this claim. The entire experiment, from my view, was conducted in Earth's reference frame. His experiment would always show light moving at the same speed in any direction (as it does). He needs to observe from 'outside' Earth's reference frame to make claims on light speed in other reference frames. Am I missing something?

Hi everyone, I'm just a physics enthusiast. I took some first-year courses a long time ago, but I wasn't able to continue, so I don't have a degree. Still, I'm really passionate about the subject and try to keep up with it as much as I can. I mostly study in my (limited) free time, going through books I didn’t get the chance to read when I was younger. Thanks for your attention!
