    Light Speed Time
Click For Summary
The discussion revolves around the relationship between time and the speed of light, with the original poster questioning if they are linked. It is clarified that speed is a measure of distance over time, making the concept of "speed of time" nonsensical. Participants explain that light always travels at a constant speed (c) in a vacuum, while the expansion of the universe is accelerating and affects how light travels across distances. The conversation also touches on time dilation and the distinction between coordinate time and proper time in relativity. Ultimately, the complexities of these concepts highlight the challenges in understanding the nature of time and light in the context of modern physics.

This is where I'm trying to get, light is not the only thing that travels at ##c##, there is a reason for that am i wrong?

Every massless "thing" travels at the speed of ##c##. That's pretty well understood.

Good Good, why? is almost like is not traveling in space but in something else, but i know that it is in space, because it can get distorted by gravity

I don't think that just by don't understanding completely makes me wrong, maybe i just can't proof it yet, I'm looking at it in new ways, i will not surrender about it yet

Proof by endless repetition?

gravity not exist as well but doesn't mean that we can't measure

This is not only wrong, but logically impossible.

I'm not trying to prove it yet, I'm just trying to understand it better, I'm only a teenager who wants to study physics in a soon future, and you guys are the experts, but i need to give my best being this dumb to understand at least a bit

You can't do that by personal speculation based on incorrect beliefs, or by throwing out further questions when you haven't even understood the answers to the previous ones. And you certainly can't by refusing to listen to what people who are much more knowledgeable than you are telling you.
