Why is the speed of light the upper limit of speed?
Could you explain this for a brainlet like me?

In cartesian coordinates what's the fastest path between two points? A straight line. Now consider a geometry more hyperbolic in nature - ie 3+1 lorentz manifold. Fastest way between two points is no longer a straight line. But we find the path light takes in vacuum is the optimal path. Just like you can't get between two points faster than a straight line in cartesian, you can't go faster than light in vacuum.

the idea is that you can treat time like a spatial dimension and get a space-time manifold, and through this manifold light kind of "rolls down" the shortest path. just like a ball on a curved sheet.
so you can't really move down a shorter path than light, cause it's already taking the shortest path.

You are right, it is more complicated. There are properties of light that relativity can not explain while the analysis of light as corpuscules can. Defraction grading is one such light property. However the geometry of general relativity is rock solid, but I don't believe it can be reconciled with quantum mechanics. However, I am looking for a geometry which is consistent with all our observations. There must be one out there.

Everything moves through spacetime at the speed of light anon, this cannot be changed.

You are sitting in your chair motionless currently, so all of your motion is through time, if you start to move through space then your movement through time must start to slow, until you reach the speed of light, at which point you would not experience time.

Any faster than the speed of light and you would be experiencing time in reverse. This is potentially what happens inside a black hole but of course that is purely speculation.

you're exactly wrong, it's been observed to not change even time and space does. and if you mean it's slower in an atmosphere that's simply because light has to take a longer path through it the actual fotons are the same always

The upper limit of speed is the maximum speed of information or better to say maximum speed of signal. By proposing the maximum speed of signal we get an invariant which is preserved in every system. The theory which describes transformation of such systems is called general theory of relativity.

Because light is the constant speed that it is, theoretically speaking, it has no speed at all. Once one thing has all the speed, it is impossible for more to be created. This being said, light has most speed but not all. Once the max is reached, light slows itself in order to preserve speed/momentum for other things. It has no "speed"

I've not even thought to apply that to my meta.
I'm currently just at from absolute void to birth.My best effort is boundary by virtue of time not existing ahead of a vector. And that boundary is only as far as the deviation is.

Becauze universe is a perfect fluid automaton, and automaton have speeds. Its logic. Fyi everything is traveling at the same speed on our scale. We dont appear to be traveling at light speed but our appearance of being a single body is an illusion. At planck scale everything is diffusing and contracting at light speed. BUT this only our scale. In reality "speed" is just a ratio. Makes more sense when you see the automaton.

These are two 'massive' systems. The clusters and voids. On paper it's easy to go we'll they're defined by each other. But to explain the causality. You've had to invent a force that's spawning.

My Meta is basically extreme Bohmian. Quantum states, observe quantum states. A wave stack. It's not measurement. But I'd guess measurable [spoiler:lit]quantifiable?[/spoiler:lit]

The nexus is true to Bohmian. Cataclysmic wave form from 0 potential.
Basically sets forth a 'partial' that's default of a vector as it's birth is only 1 reference point. You need to for a straight line.
So this makes what is essentially a 3D storage matrix of previous paths. As it knows where it's been. But can't predict what's coming beyond intersecting a previous path.

So in essence it's a absolute solid. No speed, velocity, or ongoing causality beyond the next moment of partial zero.
But where the Universe get's perception of those things. Is that the vectors are interconnected with knowledge if all connections. Good old Pi plays the part of data definition. As these were curved paths, so mathematically they have Irrationality and rationality inherent in them.

Pi is what gives perceived variance. To the 'collapsing verse'.
Pi can't be resolved. It's forever edging.
It's the equivalent of stopping after a long period of motion, but your focus still try to adjust for the motion.
Extreme case. A dolly zoom they do in Movies.

Does that satisfy your thought of fluidity in existence?

c is thought to be the "speed limit of the universe" for many a good, well-defined reason.
One is that photons (light as particles) are massless. The lower something is in mass, generally, the more affected it is by an unbalanced force.
Obviously, it's more complex than the nomenclature of classical mechanics allows for (especially since you're only going to get a fat goose egg if you plug in the mass of a photon into Newton's second law), but I find classical mechanics to be better understood by a general population.
But don't take any of our words for it. There were some pretty bright chaps at the turn of the last century that put a lot of work into figuring all this shit out so go see what they had to say about it.

Here (in picture), are Maxwell's equations in Gaussian units. If c was infinite, then the curl of E and the curl of B would both be generally zero. This would mean both B and E could always be expressed as the gradient of a scaler function. This would destroy Faraday's law of induction. Thus EM waves would never exists.

So if light is to exists, then it must have finite speed.

It’s not; it’s only impossible for objects to accelerate to as fast or faster than the speed of light, because as you accelerate, you become more massive, requiring more energy to accelerate, creating more mass, requiring more energy to accelerate, and on and on. So, an object cannot accelerate to a speed at or faster than the speed of light.

However, theoretically, there could be particles that were always traveling faster than the speed of light and never decelerate to below 3 x 10 ^ 8 m/s. These are hypothetical particles called tachyons; there’s no evidence for their existence.

Light will always need a medium In order for it to travel. This is where you get wavelength. It will still need a medium to travel between two object and use the wavelength current to propel itself. The medium is plasma. Which explains general relativity between two object. By some form of decay they experience. The idea is that wavelength slows the speed of light. It’s like a drag race vs circuit. The cars in a drag race will always reach top speeds while in a circuit it must somehow slow down for turns. Of course the turn itself has useful properties as this is where you get the perfect quantity of gravity vs inertia. It proves that these points is where light most cracks. Or rather gains some form of simple conscience due to it having to observe its turns to fulfill a route while many register it as round. It must snap around to fulfill a curve. It’s the only thing that can graduate a wavelength.

because it looks at mass conversion vs energy. For example for something to travel at the speed of light its mass is so light, what you really seem to be looking at in layman terms is the "death expansion" in which electrons escape a charge. For anything to be faster then the speed of light it needs to come from a force so great as to induce propulsion and have a smaller mass, it could be quiet possible but becomes utter useless as it would be outside of any spectrum we could visualize and possibly measure. Not to mention to travel at such speed would require a small mass by the laws of physics, and anything outside of a mass of the speed of light is useless to us and nigh impossible.

If light travels through "space" as a wave though there must be some property of space that limits the speed the light wave can travel through it though right? In the same way the speed of sound waves are effected by the elastic properties and density of the medium.

OP, to understand why nothing is faster you have to consider two things:
1) Maxwell's Equations
and
2) Galilean Relativity

1) is what >>10786224 posted. The equations describe electric and magnetic fields. By using the last two equations you can show that the speed of light is equal to $c = \frac{1}{\sqrt{\mu_0 \mu \epsilon_0 \epsilon}}$ which in a vacuum reduces to $c = \frac{1}{\sqrt{\mu_0 \epsilon_0}}$ . The speed of light only depends on two constants and is thus also a constant.
2) is the concept that the laws of physics are frame invariant. You could be standing still while I was moving or you could be moving while I'm standing still. We can't determine which of these is true, and in both cases the physics should be exactly the same.

What Einstein did was combining these. No matter how fast you are moving, you should measure the speed of light to be exactly the same as someone who's "standing still". So if you move at 50% c and measure some photon you send out, it will move at the speed of light. But to someone outside it will also be "seen" to be moving at the speed of light. That's why to not break with either 1) or 2) space and time have to change.
The effects are that lengths are contracted, time is dilated and mass increases the closer you get to the speed of light. As others have said, since your mass increases exponentially the closer you get to c the more energy you need to accelerate further. To reach the speed of light you'd need to expel an infinite amount of energy.

Because with the formula e=mc2 m being mass and e being energy and c the speed of light which is a constant. So if you want to equal c the formula becomes c=(e/m)^1/2. Acceleration would be the same thing as energy so as you accelerate e increase but to keep c constant you would need to increase m as well. So anything with mass can never reach the speed of light.

There is a limit to why that should be even if there is some philosophical arguments for it. For example, action at a distance with no limit whatsoever has plenty of issues. But if you are doing physics, you basically agree that experiment is what actually tells you what happens, even if there is no why behind it.

Its the speed of massless particles. Particles with some mass move at some speed. This requires some energy for them to move. Then you have some particles with no mass that obviously can move a lot faster. This is super fast speed.

Say you have particle A that is 10kg moving at 5m/s and partcle B that is 20kg moving at 2.5m/s. If you reduced particle B’s mass it would move faster now, if given the same energy. But if you have particle C and particle D both with 0 mass, how can one particle move faster than the other given the same energy?

The speed of light is simply the speed of massless particles. Its just how fast you happen to go when you cant go any faster by getting lighter, but cant have infinite speed because that would require infinite momentum (i think). So youre left with some finite speed that is really fast. Why that speed happens to be 3e8 m/s is just chance, it has no meaning its just what we observe

Well at first it was because they didnt observe light having any mass when early quantum mechanics forerunner scientists were measuring/discovering its basic properties, such as lights wave nature, its simultaneous particle nature, and some other stuff i forget. Then a lot of mathmatical formulism was brought into the picture that theorized in explicit terms and formulas that light had no mass. Then scientists began experimenting and verified these hypotheses.
Thats a rough sketch i believe

yeah, but... how do you measure it? as anon before said and that's logical, for macroscopic stuff you measure force of some sort. How do you measure mass of a light particle? He said "by finding their energy", what does that mean? Higher the energy needed to move it, lower the mass? how can you measure "mass" of something? You never actually measure mass of anything, it's always calculated indirectly. What's the procedure because it may be possible that it's just to small to detect

If we take quantum field theory, with Feynman diagrams and all that stuff, you can compute the classical approximation of an exchange of a large numbers of bosons carrying a force (i.e., you can recover the classical force from the quantum effects). If you do that for a massless boson you get the usual 1/r potential (1/r^2 force), while for a massive boson you have a e^(-m r)/r potential (called Yukawa potential). Because we don't see this exponential suppression at large distance for the electric interaction, we deduce that photons don't have mass (well, actually an upper bound on what their mass is).

so it's not measured? Is it possible that they do have mass, but due to other effects or the other way of functioning that mass is simply not demonstrating itself like it is for macroscopic particles? It's not my field, I'm just trying to understand since it seems like a bold statement
>>10793202
is it possible that measuring devices we have are limited to that value? because if it went 10c and you could only measure up to 1c it would show 1c no matter what. You could slow it down 5 times and still get 1c. That doesn't mean you didn't slow it down. I know there's probably some explanation, but how are actual experiments of something like that even carried out? You don't actually have to answer this since I know it's super brainlet tier, but this stuff always makes my brain be like "NO!" although it's probably correct

The scattering argument is completely wrong, brainlet. If that was the case how could transparent materials exist. Light is slowed because its oscillating electric field induces an opposing electric field in the material, which slows down the light. Fermilab did a video on this.

Unless you believe in some variant of the aether, there is no way to explain the speed of light in intuitive mechanical terms. It's just a defacto state of the system that is taken to be self evident. Imo, the speed of light is set by the properties of the medium, it is the upper limit of speed because it represents an exchange of momentum between the smallest possible particles. The medium is perfectly elastic and and superconductive. Light is just a highly coherent flow of charge between the particles of that medium, which are in direct contact with one another. The speed as it moves between particles is set by the period of the electron orbital and the angular momentum of the electron.

>is it possible that measuring devices we have are limited to that value?
nope, the fact that the speed of light is constant in all reference frames is not due to our measurement devices.
It's because it's a constant, and constants are the same in all reference frames

>You could slow it down 5 times and still get 1c. That doesn't mean you didn't slow it down.
the thing is, the speed of light depends on two constants $\epsilon_0$ and $\mu_0$ . So if the speed of light changes then either of those should change as well. That would mean that physics works differently. Which means you can provide a rest frame, and can say with confidence that you ARE/AREN'T at rest.
This is forbidden by relativity, so you can't have both. Either the speed of light can vary or all frames are equal.

>but how are actual experiments of something like that even carried out?
well, for time dilation you can measure it using satellites with atomic clocks. The clocks up there move at different rates than the ones down here. Which is partially due to their speed, but also partially due to gravity.

The relationship between light and photons is simple. When passing through a material of attuned wave spectrum and absorption, photons turn to electrical energy. Photons, while able to be INTERPRETED as waves actually carry a mass similar to an electron and are therefor more accurately defined as particles.
This in turn shows that all electrical energy is self contained, at least within the entropic values of the gravitational field which they inhabit.

the speed of light is c because that's the speed electromagnetic waves travel at

Because light doesn't interact with the Higgs field, therefore nothing alters it speed except itself. All particles with mass interact with the Higgs field, but photons are massless. That's why their speed, and the speed of massless particles, are the upper speed limit.

In short, light is massless and therefore the fastest thing possible.

well, what other explanation is there?
the speed of light can be derived through Maxwell's equations (specifically the curls of Electric and Magnetic fields)
and the calculations show that it's only dependent on the two constants ( $c=\frac{1}{\epsilon_0 \mu_0}$ )
so light has that speed because those two values are as large as they are
it's like asking "why is gravity as strong as it is?" or "why are atoms as large as they are?"

The fuck? No, the energy occupation levels of the - FREE - electromagnetic field are quantized and each quanta has the energy of

$E_{photon} = \hbar \omega$

this is what is called a photon, but the translation to space propagation and the collective behaviour of the field and it's interaction with environment is something dramatically different where the notion of a single photon fails and more advanced treatment is necessary, the result of which is ordinary Maxwell's theory which gives you the wave behaviour.

I REPEAT - we can only measure the values of the field which is described by Maxwell's equations. (bar vacuum fluctuations and sub-poissonian light)

That's the advanced treatment I mentioned, you can quite twist and blur what consists a photon especially in the theory of photodetection, the only thing that remains is the quantized energy, another way you can reveal the quantum nature of light is through correlated detections, but the image of a single photon propagating is nothing more than the propagation of a wave packet in Maxwell's theory with quantized energy.

quantized EM field is quantized from the source less version of Maxwell's equations, everything else is simply a weak perturbation or uncomputable.
