The striking thing is to realise that when Physicists ‘discover’ various particles that super-unify various string theories, these phenomena have all always existed and have been in operation since the dawn of time, we only just became aware - and when i say ‘we’, i mean Tesla, Einstein & Edward Witten, not me and nearly all of you.

@39:00 one could equally _legitimately_ say that if your theory requires supersymmetry _and_ extra dimensions for consistency it is a hint telling you your theory is likely wrong and you are not using the correct physical constraints. Is the hint saying your theory is more likely wrong than not? I could not say, I'm "just sayin". The fact a theory has gravitons is a pretty mild favourable result, since gravity occurs in any theory which is generally covariant (respects position and rotation gauge invariance). I think strong theory is the right conceptual idea, but it is not well formulated, and finding alternative extended object models for matter that are minimalist (4D spacetime, no supersymmetry) is something more people should be working on.

[@malootua2739]

Ok, so I get it! "Stuff" is crystalized "spacetime! There you go! I figured it all out! (lol) See - there is just SO MUCH spacetime, an INFINITE amount, so much of it that there's a tiny bit of "residue" from it all - and that "residue" is "matter"

Is he a physicist or mathmatician. I’m just lost on this

[@lochvast1180]

Think about an explosion creating shockwave through air. If you run toward or away from the explosion, it will take less or more time for that shockwave to reach you. The shockwave moves at the speed of sound and only at the speed of sound. However, photons created in the explosion will reach you in the same exact amount of time regardless of where or how you move. The only thing that changes is the frequency of the light. However, this is only from your perspective. Another observer further away will see the light reach you at different at different times, depending on your motion. This is nearly impossible to detect in ordinary circumstances, but boy, is it weird. What does it mean when two different observers have two different observations of the same reality? This is where I understand the time component comes in, shifting in it's rate, to compensate for the difference between observers?

[@sntk1]

Schrödinger: If you ask a physicist what is his idea of yellow light, he will tell you that it is transversal electromagnetic waves of wavelength in the neighborhood of 590 millimicrons. If you ask him: But where does yellow come in? he will say: In my picture not at all, but these kinds of vibrations, when they hit the retina of a healthy eye, give the person whose eye it is the sensation of yellow. Weyl: The characteristic of an n-dimensional manifold is that each of the elements composing it (in our examples, single points, [...] colors, tones) may be specified by the giving of n quantities, the "co ordinates," which are continuous functions within the manifold. EPR: ...every element of the physical reality must have a counterpart in the physical theory.

The acceleration of acceleration is called jerk. Jerk is not acceleration the same is displacement isn't velocity.

[@markkennedy9767]

1:45 is the real peculiarity of the speed of light not that it is independent of its source speed but that it is independent of the observer's speed. Since mechanical waves are independent of their source's speed also. So has he misspoken here. I cant believe i'm correcting Ed Witten.

Well no, why? The closer you go to the speed of light the slower time flows, meaning photons don't actually experience any time at all so if you moved at the speed of light time would stop for you and let's say in 0s an infinite time would pass outside your reference frame. I hope that this helps

[@kennethclayton1526]

Dank, There is no such thing as 'the speed of light' any more than there is a speed of water, or rocks. There are as many speeds as there are influences on a partical/wave, by a massive object. Eddington proved that. Leave the flashlight in the glove box-until you get a faster car.

Correct! It is a 1 dimensional manifold, though the behavior of an "open" string matches that of a violin string and a "closed" string a rubber band. The one dimensional generationalization isn't even quite correct, the abstract object is a "brane", a 0 dimensional brane is a point, 1 a string, and 2 a membrane. The beautiful analogy to a musical instrument shouldn't fool you into thinking the behavior of strings is simple, dirichlet branes aka d-branes are crazy weird.

Dr Written, I have a question..when you blow a balloon, and when we say that balloon is expanding, then something is expanding it which is air in this case..but when we say that space is expanding..what is expanding it? What is the fabric of space made up of? If the space of fabric is made of something then it means that the big bang is still happening and there is a fundamental energy or force that is pushing everything and creating time as well. If we could figure it out I think we would be able to find different dimensions of time as well.

[@mathematicalmonk1427]

Space is not made of anything like that but the reason for expansion of space is thought to be dark energy

[@PepeNuclear]

What he means by space expanding is the space between galaxies

[@theGraphicAutist]

Wow it the 1st person besides myself that has ever mentioned wondering that! If we describe the big bang like an m80 going off, what constitutes the "bang?" From the time it starts till it's no longer seen or heard. So the big bang did not happen 13.8 billion years ago! We are in the midst of it right now. And if time is relative, I believe that when there wasn't a lot going on, B4 novelty, time would have been perceived differently. So I think either there was and is still acceleration, or since time is related to matter and novelty, things we think happened in milliseconds actually took longer but we're thinking of time as linear. What u think? I been thinking about this long time

[@INN3XX]

mind you this is all my opinion and you can discard it as you will but I'm likely never to agree with GR and QM and the consensus scholars likewise me, for I have found no convincing evidence to suggest that spacetime is a real thing beyond a conceptual tool for measurements nor that light is non-mechanical or a wave-particle duality. also, no thing can be a wave-particle duality for this is an irreconcilable contradiction and a lackadaisical description thereof. GR is merely a few presumptive equations conceptualized by observing for example the path in which two celestial sized magnets travel as their fields impress upon each other. the appearance of light curving around massive objects is merely the faraday effect on a grand scale. Gravity also is not the acceleration of mass toward mass along the curve of space time but the acceleration toward a null pressure point between the two fields. light is a field perturbation modality rather than a particle-wave and is in other words a disturbance in the medium in which it travels along, within and cannot escape from. so you need to understand what manifests empty space to know what that medium is. there is a missing component to the EM and EMR model which is dielectricity and this is that invisible inert energy field that is responsible for the existence of everything in the physical universe. there are only two types of geometry and that is the physical and field geometries. what manifests empty space is magnetism and what manifests electricity and illumination is the impression of the magnetic field upon the dielectric field as the electric field converts into the magnetic and so on. so the dielectric field is inertia and the magnetic field is the loss of that inertia and they necessitate polarity and the electric field is the hybridization of the two which then results in the field perturbation modality that is light. it is typically thought that the electric field and magnetic create each other but this is an incorrect description of the phenomena to justify the idea of light being self propagating or non-mechanical. everything within the physical geometry is light and everything outside of it is of dielectricity. so when the dielectric overcomes the magnetic, light vanishes from the physical universe ie becomes a black hole. the mass maintains but is converted into inert energy and you can no longer see it and these same principles explain atoms and so called subatomic particles. subatomic particles are essentially descriptions of various modalities of the proton which is electrostatic. this means that atoms are essentially electrostatic dynamos or spherically harmonic manifestations of high energy light. electrons do not exist but are merely units of diectric discharge due to the spherical harmonics of the electrostatic dynamo. all this is a simplified description and explanation of a new unifying model where gravity is merely a modality of magnetism and light is a field perturbation modality of the three fields that are one and necessitate each other's existence(dielectric field, magnetic field, electric field), but to the average human mind this will likely appear as a pile of word salad and excrement, but to a true academic with an open competent faculty of mentation it will prove to be worth investigation and the inevitable truth that persists through scrutiny and lies.
