Not sure if this is the right place, but I don’t know where else to post it. Astronomers and astrophysicists seem to be pretty similar these days. By first obtaining a degree in physics related to these careers, are these career paths almost interchangeable? (Considering that astronomers might...

This may be a rather ridiculous inquiry, but Google queries haven't helped much. As I understand it, different colors (wavelengths) of light move at the same speed in a vacuum, which together make up what is often called "white light." However, when light enters the Earth's atmosphere, its...

Indeed. I wasn't sure what was meant by This makes sense. I wasn't sure what was meant by space expanding faster than light. From our perspective, at a set velocity i.e.

I've heard it said multiple times on here and elsewhere that as we "wind back the clock" of our Universe and the Big Bang that our laws of physics kind of begin to fall apart, in a sense. If this is true, can anyone explain exactly which laws become more difficult to work with, and why? Thanks.

It's generally understood that nothing can be accelerated up to the speed of light, and that nothing can surpass it. That being said, the expansion of space itself can exceed this "universal speed limit," as the Universe is expanding so fast that light can't catch up to it. Regarding the...

I did consider this, as the sensors are practically just more observers. But it would seem that there would truly be a correct "reality" under it all, regarding the lightning, but that it's just impossible to find out which. Making it that everything appears like it actually happens a certain...

Is it not perception to acknowledge that the event being observed is relative? After all, it would be assumed that, in reality, one of the observers is correct, but we just have no way of knowing or figuring out which one is.

My question is based around the popular thought experiment regarding Einstein's relativity of simultaneity. That is, the one regarding two lightning strikes and two observers. Observer 1 is stationary relative to the ground, and is located equidistant between lightning strikes A and B. Observer...
