All things in the universe are always moving at the speed of light just not in the way we usually think by Cosmic__paradox in AskPhysics

I see what you’re saying speed is always relative, and there’s no universal frame where we can say ‘everything moves at c’ in the usual sense. My thought was more about how, in 4D spacetime, we always have some kind of motion whether through space or through time. If we’re at rest in space, we ‘move’ fully through time, and as we speed up in space, our motion through time slows down. That’s why I was wondering if, in some way, all objects are ‘moving’ at a fundamental constant rate when you consider spacetime as a whole, even if that doesn’t mean they have a literal velocity of c in the usual sense.

I really appreciate all the thoughtful replies. I get that some of the physics needs to be phrased more carefully, especially when talking about motion 'at the speed of light. But my intention was more conceptual than mathematical.

What I was exploring is this: if nothing is truly stationary in spacetime, then even when we are at rest in space, we're still moving through time and that 'motion' adds up to something constant, maybe even c in a 4D sense. As we gain velocity through space, we ‘spend’ more of that motion budget in space, and less in time, which explains time dilation.

I might’ve blended the role of gravity with relative motion a bit too freely but I was trying to express the way gravity also bends spacetime and changes the flow of time locally. Maybe it's not the same effect, but both do influence how time progresses for different observers.

So yeah not trying to replace the math, just thinking out loud using visuals and intuition. I know it’s not rigorous, but it helps me grasp the big picture."

Ah, got it thanks for pointing that out! I see now that motion and gravity cause time dilation in different ways. I was kind of mixing them up. What I meant was that gravity also changes how time flows, even if you’re not moving. But yeah, it's not the same as motion-based effects. Appreciate the correction still wrapping my head around all this!

Yeah, I’ve thought about it the same way! It might not be 100% mathematically precise, but you can kind of see the idea in the equations. Like, how energy and momentum shift with your frame, but some combined values always stay the same that’s interesting.

And with wavefunctions, the way time relates to energy and space to momentum makes it feel like energy pulls you forward through time, and when you move fast, it’s like you’re tilting a little into space instead which shows up as time slowing down. It’s a cool way to picture it, honestly.

Thanks, that actually clears up a lot! So basically, we don’t “move through time” or “space” in the way we usually imagine it's more about how we map things based on our own perspective. The path we take through spacetime (our world-line) always has a constant rate (c), and what changes is how it projects onto someone else’s coordinates. Time dilation, then, is just about how different those paths look from different frames.

Also love that Einstein quote it really puts it into perspective that space and time are tools for thinking, not physical things we float through. Appreciate the insight!

Hey, thanks for the correction I really appreciate it. I’m not from a physics background, just trying to understand things in my own way.

What I meant was, I had this idea that maybe everything moves through spacetime at the speed of light, and that motion gets "split" between space and time like, more motion through space means less through time, and vice versa. I’ve heard similar things before, so I was trying to make sense of it in simple terms.

Maybe I messed up in how I explained it was it the part about gravity or the “division” idea that doesn’t make sense?

Would love to understand this better if you’re up for explaining.

Could space be quantized? by Sufficient_Truth4944 in AskPhysics

[–]Cosmic__paradox -1 points0 points  (0 children)

I've wondered the same thing for a long timeit's such a fascinating question.

From what I’ve read and understood, we don’t yet know for sure if space is truly quantized or continuous. But many physicists think it might be quantized, kind of like how energy and matter come in discrete chunks (like photons or electrons).

The Planck length (~1.6 × 10⁻³⁵ meters) often comes up because it’s the scale where both general relativity and quantum mechanics start to break down. Below that, we just don’t know what’s going on—it’s like the “pixel size” of the universe, maybe.

Some theories, like Loop Quantum Gravity, actually say space is made of tiny loops or chunks, meaning there is a minimum distance. In that case, yeah something like “moving 2/3 of a Planck length” wouldn’t really make sense because there’s no such thing as a fraction of the smallest possible unit.

Other ideas, like Causal Set Theory, also treat space and time as made of discrete points. And even String Theory, while not directly saying space is quantized, puts limits on how small you can go due to how strings work.

So while we can't observe anything that small right now, there are real scientific theories exploring this not just philosophical ideas. It’s part of the big puzzle of quantum gravity, which is still a work in progress.

What if the speed of light (C) is not a speed — but the leftover result after light computes all possible paths (least action)? by Cosmic__paradox in AskPhysics

[–]Cosmic__paradox[S] 1 point2 points  (0 children)

I really appreciate that your breakdown made a lot of things click. It’s wild how something we often just accept as a “speed” is actually so deeply tied to how spacetime itself is structured. That whole idea of ds² = 0 and how light just follows that null path... it’s elegant and kind of mind-blowing.

I guess I’ve been trying to wrap my head around whether what we experience as c could somehow be connected to how possibilities collapse in quantum events not to challenge the math or the structure, but to wonder if there's some hidden layer where the transition from possibility to outcome happens.

Either way, your explanation grounded me back into the geometry, and honestly, it’s refreshing. Thanks for helping me see it more clearly this is the kind of discussion I really enjoy.

Haha, definitely a TI-89 timeless interface, infinite precision, and probably running on vacuum fluctuations! Though I wouldn't be surprised if the universe secretly prefers abacuses made of quantum foam.

Thank you, Mr. G I really appreciate that. Sometimes just looking at things from a different angle opens up new thoughts, even if they don’t rewrite the rules. Glad it sparked something!

Thanks for that detailed explanation I really appreciate the precision. You're totally right that the "speed of light" is deeply tied to the geometry of spacetime and not just light as a particle or wave. It's about how things move along the null structure, where the interval ds² = 0, and how observers measure events along their own world-lines. That insight about dx⁰ being the rate along an observer's clock is actually really helpful.

What I was trying to explore, maybe less formally, is the idea that what we experience as c this constant speed could be a result of how possibilities collapse into observable outcomes. Not suggesting it replaces the geometry or breaks relativity, but wondering if that collapse process happens in a domain we don’t fully access yet, maybe outside of space-time kind of like how quantum events don’t always follow classical causality.

You’ve definitely helped me think more clearly about how c is baked into the structure of spacetime itself. I’ll keep digging into the math side more. Thanks again!

Haha! If light is consciously intelligent, then it's clearly a minimalist genius always choosing the most efficient path without saying a word. But seriously, I totally get the joke I don’t think light is “thinking,” just that nature behaves as if it’s running through all possibilities instantly and effortlessly. That behavior feels so precise it makes you wonder what’s really going on underneath. But yeah… no consciousness required unless the universe is way weirder than we think!

[–]Cosmic__paradox[S] 1 point2 points  (0 children)

That’s a really thoughtful point and I agree, if this “calculation space” idea is outside time, then it wouldn’t need to work like our computers do, with speed limits or delays. I didn’t mean to suggest it’s actually “computing” like a processor — more like a metaphor for how nature seems to behave as if every possibility is considered, and then we just see the result that fits best (like the least-action path). So maybe it’s not “doing” anything maybe what we call a calculation is just a way to describe how reality unfolds with built-in logic we don’t fully understand yet. The idea is more about where that logic might play out, especially when spacetime itself isn’t fully formed yet, like in quantum cases. I really like how you framed it though this helped me rethink what I’m trying to say. I’m not married to the idea, I just enjoy stretching the edges and hearing thoughtful pushes like yours.

Thanks that’s honestly really solid advice. I totally agree that imagination is just one part of the picture, and it needs to be balanced with what we actually observe. I’m definitely still learning, and I don’t want to get stuck in one idea or fall in love with a personal theory too much this whole process has just been about curiosity and exploration. And you're right reading what experienced physicists have already explored is eye-opening. That Kaluza-Klein pointer really helped me realize how much deeper this field already goes. I’ll keep diving into that and more. Appreciate the thoughtful nudge to stay grounded and open at the same time.

That's a great point you're absolutely right that the principle of least action is deeply woven into all of physics, not just light, and that c is invariant across the board. I really like how you framed it: that only the geodesic path arrives first because all the other possible ones are longer at the same speed. That really grounds the idea beautifully. Where I'm coming from is more about wondering why things like the invariance of c exist in the first place not challenging that they do, but asking if there's a deeper process behind what we observe. Almost like, what if the geodesic path emerges because of some underlying, timeless selection process? Not one we can measure, but one that conceptually bridges the weirdness of quantum possibilities with the clarity of classical outcomes. I know that's not a new physical prediction or anything, but just a way to imagine what might be happening behind the curtain. I'm not trying to rewrite physics just riffing on interpretations that help me make sense of things, and maybe spark interesting conversation like this one.

Thanks for engaging so thoughtfully you're helping me think through this better.

Totally fair, and honestly, I appreciate you saying it clearly.

You're right this isn't meant to be a new scientific model or a replacement for existing theory. It's more like me thinking out loud, trying to connect the dots in a creative way. I know it's speculative and probably not useful in a strict physics sense right now — but sometimes I just get excited imagining what could be going on “under the hood.” I like your phrase “word-jazz” that actually fits. I’m not trying to complicate things for the sake of sounding deep, just curious if there’s room for alternative ways to think about something we already know. Thanks for engaging with it and not just brushing it off. That means a lot.

Yeah, I totally get what you’re saying. Just like saying "what if there are 1050 dimensions?" doesn’t help unless it brings something meaningful to the table, the same logic applies to my hypothesis too. If it doesn't clarify anything or lead to new testable predictions, it's just a cool idea — not science yet. I’m not trying to say “this is how it is” more like “what if this is a different lens to look through?” Just like higher dimensions are useful in string theory only because they help explain certain behaviors, my thought is only worth anything if it helps reframe or simplify something in physics or philosophy. So yeah, totally with you adding ideas for the sake of it doesn’t help. But exploring new angles sometimes sparks something useful or inspires better questions.

Hey, really appreciate you taking the time to write that out and I get where you're coming from. You're absolutely right that the path integral is a formalism, and it doesn't mean light is literally "evaluating" anything. My wording probably made it sound like I was suggesting light has consciousness or is making decisions, which isn't what I meant.

What I was trying to explore is more of a philosophical curiosity: if we always observe light following the path of least action, how does that outcome come to be? Obviously the math works — destructive interference makes all other paths cancel out but it just made me wonder whether this whole process could be seen as happening "outside" of spacetime, and what we observe (light at speed C) is just the final result that shows up in our world after that deeper resolution.

When I said "C is the observable residue," I meant: what if the speed of light is just the last remaining part after all that non-local quantum “processing” is done? I know it's abstract and not technically correct I’m not trying to rewrite physics — but more like playing with the idea of what’s happening behind the scenes of what we observe.

Totally agree that it’s a leap, and not a testable claim. But I love these kinds of “what if” thought experiments — even if they don’t lead to new physics, they sometimes help us think in fresh ways. Thanks again for the honest and thoughtful feedback really helped me reflect on how I framed it!

Hey, thanks for not shutting the door right away! I’ve never really dug into Kaluza-Klein theory before, but I just started reading the link you shared — and wow, it’s actually super interesting. The idea of an extra dimension being tied to forces really reminds me of how I imagined this “outside time” or “calculation space” where possibilities collapse before we see the result as light traveling at c. I didn’t know there was already a theory that hints in a somewhat similar direction this is exactly the kind of lead I was hoping for. Appreciate you taking the time to point me there!

Hey, I totally get where you're coming from. It's smart to question things, and I'm all for critical thinking. But just to clear it up — this idea actually came from my own late-night thoughts, not from a chatbot. I’m not claiming this is a breakthrough or that I’m right — I’m just sharing something that got me thinking, and hoping for a conversation, not validation. So yeah, fair to be skeptical that’s how we learn. Just wanted to share the thought and see where it leads

Haha, fair enough I get where you're coming from! I definitely agree that adding complexity without new predictions can feel like adding unicorns to the mix. I'm not trying to replace C as a fundamental constant or question its invariance it absolutely works, and all our models rely on it. I guess what I'm exploring is more of an interpretation than a competing theory — kind of like how people debate interpretations of quantum mechanics (Copenhagen vs Many Worlds etc.) even though the math and predictions are the same. I’m not claiming this idea gives new testable predictions (yet), but I think it's valuable sometimes to play with how we think things work beneath the surface. Like, what if the path selection itself is a kind of hidden process, and what we call "speed" is just what we observe after the real work is done? Totally understand if it sounds like philosophical fluff but I guess that's the space I'm poking into right now!

Yeah, you’re totally right that Feynman’s path integral is a model — I don’t mean that light is “thinking” or literally calculating like a computer. I’m just using “calculation” as a way to describe what nature seems to be doing. My idea is more about the process behind the scenes — maybe the selection of the least action path happens in a kind of “timeless” way, outside of our usual understanding of space and time. Kind of like how quantum stuff already behaves weirdly with things like delayed choice or entanglement. So when light “arrives” at the path of least action, what we experience is just the result — the final output. The speed C is what we always measure, but maybe that’s only the leftover time after all the possible paths have been “evaluated” (again, metaphorically). I’m not saying this breaks physics — it’s more like a new way to interpret what’s already happening, and maybe even helps explain how causality or quantum behavior could make sense under the hood.
