Ludovic Berthier: Is Glass a State of Matter?
Переглядів 983 місяці тому
Glass is everywhere. We use and are surrounded by glass objects which we then naturally consider as a distinct state of matter. Yet, glass as we know it is obtained by rapidly cooling a liquid below its melting point to avoid crystallisation. The viscosity of this supercooled liquid increases by many orders of magnitude upon cooling, until the liquid becomes arrested on experimental timescales ...

    Experiments now show that the speed of light is not a constant, as once thought, and this has extraordinary implications to Relativity, Gravity, Quantum Mechanics, and even Quantum Field Theory. Hi, my name is Dr. William Walker and I am a PhD physicist with over 30 experience on this topic, and was the topic of my thesis at ETH. The speed of light is not a constant speed as once thought, and this has now been proved by Electrodynamic theory. EM simulations, and by Experiments done by many independent researchers. The results clearly show that light propagates instantaneously when it is created by a source, and reduces to approximately the speed of light in the farfield, about one wavelength from the source, and never becomes equal to exactly c. This corresponds the phase speed, group speed, and information speed. Any theory assuming the speed of light is a constant, such as Special Relativity and General Relativity are wrong, and it has implications to Quantum theories as well. So this fact about the speed of light affects all of Modern Physics. Often it is stated that Relativity has been verified by so many experiments, how can it be wrong. Well no experiment can prove a theory, and can only provide evidence that a theory is correct. But one experiment can absolutely disprove a theory, and the new speed of light experiments proving the speed of light is not a constant is such a proof. So what does it mean? Well a derivation of Relativity using instantaneous nearfield light yields Galilean Relativity. This can easily seen by inserting c=infinity into the Lorentz Transform, yielding the Galilean Transform, where time is the same in all inertial frames. So a moving object observed with instantaneous nearfield light will yield no Relativistic effects, whereas by changing the frequency of the light such that farfield light is used will observe Relativistic effects. But since time and space are real and independent of the frequency of light used to measure its effects, then one must conclude the effects of Relativity are just an optical illusion. Since General Relativity is based on Special Relativity, then it has the same problem. A better theory of Gravity is Gravitoelectromagnetism which assumes gravity can be mathematically described by 4 Maxwell equations, similar to to those of electromagnetic theory. It is well known that General Relativity reduces to Gravitoelectromagnetism for weak fields, which is all that we observe. Using this theory, analysis of an oscillating mass yields a wave equation set equal to a source term. Analysis of this equation shows that the phase speed, group speed, and information speed are instantaneous in the nearfield and reduce to the speed of light in the farfield. This theory then accounts for all the observed gravitational effects including instantaneous nearfield and the speed of light farfield. The main difference is that this theory is a field theory, and not a geometrical theory like General Relativity. Because it is a field theory, Gravity can be then be quantized as the Graviton. Lastly it should be mentioned that this research shows that the Pilot Wave interpretation of Quantum Mechanics can no longer be criticized for requiring instantaneous interaction of the pilot wave, thereby violating Relativity. It should also be noted that nearfield electromagnetic fields can be explained by quantum mechanics using the Pilot Wave interpretation of quantum mechanics and the Heisenberg uncertainty principle (HUP), where Δx and Δp are interpreted as averages, and not the uncertainty in the values as in other interpretations of quantum mechanics. So in HUP: Δx Δp = h, where Δp=mΔv, and m is an effective mass due to momentum, thus HUP becomes: Δx Δv = h/m. In the nearfield where the field is created, Δx=0, therefore Δv=infinity. In the farfield, HUP: Δx Δp = h, where p = h/λ. HUP then becomes: Δx h/λ = h, or Δx=λ. Also in the farfield HUP becomes: λmΔv=h, thus Δv=h/(mλ). Since p=h/λ, then Δv=p/m. Also since p=mc, then Δv=c. So in summary, in the nearfield Δv=infinity, and in the farfield Δv=c, where Δv is the average velocity of the photon according to Pilot Wave theory. Consequently the Pilot wave interpretation should become the preferred interpretation of Quantum Mechanics. It should also be noted that this argument can be applied to all fields, including the graviton. Hence all fields should exhibit instantaneous nearfield and speed c farfield behavior, and this can explain the non-local effects observed in quantum entangled particles. *UA-cam presentation of above arguments: ua-cam.com/video/sePdJ7vSQvQ/v-deo.html *More extensive paper for the above arguments: William D.

    Everyday reality: the cat exists and is something but it died and overtime we observed it decompose into nothing. So can the existence be reverse engineered? Can something come from nothing? Possible maybe but probable? Absolutely not! How could something come out of nothing? Quantum reality: no everyday language of our spectral duality wont do! It's to simple. The questions are more like how did something x and nothing y come out of what z?now you get the despairing sense of what our curiosity is up against when it comes to fundamental knowledge of existence. It requires a level of sanity and imagination that the question implies is beyond our understanding. It's like feeling an invisible wall. Not glass but an invisible wall that leaves us feeling confounded even though we know the invisible wall is there. We just have no idea what it is that is stopping us. We need instances of scientific discovery that inspire hope if our science is to live to see any profound truth of existence.

    Very understandable.. but. Taking all the direction arrows, add them up, cancel the matching ones out, place the arrows remaining in a line, square it up and you get probability.. what determines the length of the arrow? Why the arrowhead with 3 following dots.. why not 4 or 2? Which then would change the size of the square. I'm sure it's something simple that I missed or didn't understand.

      Agreed, let me split the elements at play here: On one layer, there's the distracting background audio of the original language. On the other layer, there's an English dubbing with an equally distracting thick accent. The result is sensory noise, in a narrative that is, by its' nature, already complex and abstract, meaning that the less distractions there are, the easier it is to understand. Too distracting, I could not continue after a couple of minutes.

      From observation, (nothing has ever been observed acting faster than the speed light,) and from theory, Special Relativity which explains perfectly why no effect can ever happen faster than the speed of light. This is high school stuff and is actually quite straightforward. As for what light is, it's simply a local effect of an electromagnetic field also well described and explained by theory, Maxwell's equations for example. This is science mate and you're not allowed to just make stuff up.

      @danielpaulson8838 Місяць тому

      Just look at the source. It’s there. The eye is a receptor like a satellite dish. Your brain interacts with the wave when it hits the eye receptor. If you have a satellite signal coming in, but the antenna was pointed off beam, it doesn’t see it. But it’s there. You can see it by looking at the source or like you said, it bounces off something but you still have to look at the reflected surface. Think of it like this. A radio station puts out a signal but it’s invisible and we don’t see nor hear it. We do not interact with it. Unless we tune in our radio which replaces looking at light as EM and listening to EM radio waves at a different frequency. The waves are all there. We just have to interact with them or we don’t know they’re there.

      Light most definitely is NOT invisible!! 😱Furthermore, there’s absolutely zero need for it to be separated through a prism or reflected off anything for it to be seen/sensed… I can guarantee you that if you get a laser and point it into your eye, you’ll DEFINITELY be able to see it. 🤯🫣No need for any prisms, surfaces or anything else at all. Your statement is devoid of logic and your reasoning isn’t sound. 🤓Consider that there’s also no requirement for reflection, to be able to observe light. Reflection is only needed if you want to view an object; light from a star or a lightbulb doesn’t need to reflect of anything whatsoever so that we can see it. When the light comes directly to our eyes, that’s all which is needed to be able to see light. Not sure that you’ve realised, but if something is invisible, that, by definition means we can’t see it. If light was invisible, how do you explain night turning to day?🤔
