Comment on The speed of light
NocturnalMorning@lemmy.world 1 week agoI want to know why it works that way. I’m pretty sure we don’t actually know why that is a law of nature, just that it is. Some of these things I learned in physics I was frustrated that we can’t explain the why. We just kind of know this is what experiments tell us, and the math.

If you mean the relativity part, to my understanding space and time are basically a shared dimension, so the faster something is moving in space the slower it’s moving in time. Why it’s shared, I have no clue.

We don’t actually know that space and time are a shared dimension though. Relativity treats it that way mathematically, but we don’t know what space and time are. I’m also just one of those people who want to know the answer to everything, so when the answer is we don’t know, or it works that way bcz it works that way frustrates me.
Even the idea that space and time are interconnected seems like an incomplete explanation to me.
To me, there’s no reason space and time have to be connected. But they obviously are.
My favorite theory is that time isn’t real, just an extremely stubborn illusion. Fun to think about, really difficult to prove.

Well strangely a lot of things are “it just works that way,” at least to our current understanding, like gravity, electromagnetic forces, things tending towards lower energy states. We could conceivably live in a universe where a ball doesn’t roll down a hill, it just stops where it is and retains its energy.
I saw something called the “fine tuning argument” that said there must be some higher power because our universe could not exist without those constants being what they are, but we also wouldn’t exist to experience it otherwise so ¯\(ツ)/¯

You mean Aristoteles? Many of your questions belong to philosophy not physics, give it a try when you need answers!
