  • Steven Hawking was certainly a brilliant mind, though his contributions to fundamental physics cannot be compared to a Newton or Dirac. The marketing of the brand "Hawking" then prompts some questions...

    Most physics research depends on political charity. The big problem is the distribution of funding by grants. There is also information hiding. For example, for a long time our government supressed research on quaternions, If someone did original research on quaternions for a masters thesis, the government made sure it did not get indexed. In their hubris, they were sure the Soviets couldn't figure out the trajectories for ICBMs if we didn't talk about quaternions in the literature. If you find one of these rare papers, the bibliography will likely have only Hamilton's original paper and a few more no later than 1950. They stopped this when our own people started dying due to guidance computer failures on interceptors that would maneuver through the pole of the local coordinate system, generate a divide by zero error and reboot. Intercept failed, people died. Eventually, they realized that the Soviets had figured things out a long time ago and we were just shooting ourselves in the foot. The equivalent of friendly fire.

It’s actually refreshing to hear someone saying this out loud while still maintaining respect. Yes of course Hawkins was a genius who contributed to the body physics but he did so while suffering an incredibly debilitating & progressive disease. Therefore his celebrity is a function of what he overcame to make those contributions rather than the size of those contributions themselves.

    I'm just gonna say it: I have very, very serious doubts about his capacity to write the many of the books that he did. There was a long stretch of time where he could only communicate with blinking to generate a small number of words per hour. I think it's extremely likely that much of his later works, as well as many of the "speeches" he gave through his iconically robotic sounding speech generator were ghostwritten and that certain scientific minds were definitely using his celebrity and influence to push ideas in his name - with or without his consent.
    It's existentially horrifying to consider, but it's nevertheless something any rational person must. How would anyone know if he was? Would we even know if he objected to what was being said in his name? It's not as if he could protest in any way. Thus, it's entirely possible that he was a total prisoner in his own body, calling out for help as his handlers trotted him out again and again to push their agendas - what could he have done to stop anyone from doing so?
    If this was the case, then he was an abused celebrity, indeed.
    EDIT: I started typing this before I got to the end of the video - you're the first person who's discussed the issue that mamy of works were most likely ghostwritten. Well done - I obviously agree!

      I think this may be a bit of a stretch; though he could not move much, Hawking did have control of facial muscles and made obvious facial gestures, including smiling. He would smile in time to jokes as his "voice" spoke them.
      It is possible that many or all of his books and public speeches/interviews/appearances were ghostwritten, but I doubt it was without his consent. It could also just be some Stockholm syndrome or whatever, people are weird and can seem happy even under duress.
      But I really doubt he was a literal captive, a human cash cow being wheeled around for money. That is very illegal, which hasn't stopped people before, but someone would have said something, surely. He did sit around and chat with other physicists and work on physics problems with them in documentaries, and these are real physicists, and he didn't seem controlled or anything

    It's anthropocentric to immediately demand that a mathematical model be testable by us meat sacks at the present time. The ToE when it arises will most likely look impossibly highfalutin to the uninitiated. It will look like a string theory or some such. It's a nice ideal to have things be testable but we may just have to wait on some big developments to reach that point. To criticize a model like string theory for "having no basis in reality" is anthropocentric because we can only approach knowledge of absolute reality from the limited vantage of our corner of apprehension. Our minds, however, aren't always so tethered to immediate experience, which is how we get developments like relativity and QM in the first place. Do you think both of those models received the criticism that, "they have no basis in reality" when they came out? I'll bet they did.
    We may get to a point that "testing" a theory or model might take the form of running it as a simulation on a computer or quantum computer, and seeing if that model generates something resembling our observable universe.

    @shawns0762 Před rokem +1

    I agree, for some reason people don't know that Einstein repeatedly said that singularities are not possible. In the 1939 journal "Annals of Mathematics" he wrote "the essential result of this investigation is a clear understanding as to why the Schwarzchild singularities (Schwarzchild was the first to raise the issue of General relativity predicting singularities) do not appear in physical reality. Although the theory given here treats only clusters whose particles move along circular paths it does seem to be subject to reasonable doubt that more general cases will have analogous results. The Schwarzchild singularities do not appear for the reason that matter cannot be concentrated arbitrarily. And this is due to the fact that otherwise the constituting particles would reach the velocity of light."
    This phenomenon is illustrated in a common relativity graph with velocity (from stationary to the speed of light) on the horizontal line and dilation (sometimes called gamma or y) on the vertical line. Mass that is dilated is smeared through spacetime relative to an outside observer. General relativity does not predict singularities when you factor in dilation. Nobody believed in singularities when Einstein was alive for this reason.
    Wherever you have an astronomical quantity of mass dilation will occur because high mass means high momentum. 99.8% of the mass in our solar system is in the sun
    99.9% of the mass in an atom is in the nucleus. If these norms are true for galaxies than we can infer that there is 100's of trillions of solar masses at the center of common spiral galaxies. There is no way to know this through observation, there is far too much interference, dilation and gravitational lensing. If we attribute a radius to these numbers than we can calculate that relativistic velocities exist in these regions.
    The mass at the center of our own galaxy is dilated. In some sublime way that mass is all around us because as the graph shows we are still connected to it.
    Einstein formulated relativity before the existence of galaxies was confirmed. It's clear that the mass is dilated though the galaxy and not the universe as a whole.
    The greatest mystery in science is the abnormally high rotation rates of stars in spiral galaxies (the reason for the theory of dark matter). It was recently discovered that low mass galaxies (like NGC 1052-DF2) have normal star rotation rates. This is what relativity would predict because there is an insufficient quantity of mass at the center to achieve relativistic velocities. This is virtual proof that dilation is the governing phenomenon in galactic centers, there can be no other realistic explanation for this fact.
    If you pose the question "why can't we see light from the galactic center?" the modern answer would be because gravitational forces there are so strong that not even light can escape (even though the mass of the photon is 0) Einstein's answer would be because the mass there is dilated relative to an Earth bound observer.
    Einstein's answer explains the greatest mystery in science.

      Ok, the idea would be if all the mass and energy of the universe filled a bounded subset of the space R^3, and light tried to escape from it, it shouldn't be able to.
      I don't think that there is a serious claim of our universe having an edge. It could be curved hypersurface "ending into itself", but then there is no inside, no outside, and nowhere to draw a Schwarzshield radius around. Even if the universe is massive and small enough to trap light, the light is pulled equally from all sides and hence can escape the pull of mass, hence there is apparently no paradoxon at all.
      Still, it is a cool concept.

The more mass a thing has, the less dense it needs to be to have a particular strength of gravity. Hence Jupiter has over 2.5x the gravity of Earth while having less than a quarter of the density.
      And I don’t see anything wrong with the idea that the universe itself might be a black hole (or inside of one). That would be fascinating and would lend support to Lee Smolin’s hypothesis of cosmic natural selection.

Like a cosmic Russian doll, virtually nested states are subject to "parallel processing" and "rescaling functionality" of every last state or frame of reference thereto, thereby giving a straightforward explanation for time-frame dilation, "dark" matter & energy, and even favorable genome selection, namely via cross-temporal feedback inherently maximizing overall "systemic self-utility".

      For some reason people don't know that Einstein said that singularities are not possible. In the 1939 journal "Annals of Mathematics" he wrote "the essential result of this investigation is a clear understanding as to why the Schwarzchild singularities do not exist in physical reality. Although the theory given here treats only clusters whose particles move along circular paths it does seem to be subject to reasonable doubt that more general cases will have analogous results. The Schwarzchild singularities do not appear for the reason that matter cannot be concentrated arbitrarily. And this is due to the fact that otherwise the constituting particles would reach the velocity of light."
      We have all heard the phrase "mass becomes infinite at the speed of light" this phenomenon is illustrated in a common relativity graph with velocity (from stationary to the speed of light) on the horizontal line and dilation (sometimes called gamma or y) on the vertical line. Mass that is dilated is smeared through spacetime relative to an outside observer.
      General relativity does not predict singularities when you factor in dilation. Einstein is known to have repeatedly spoken about this. Nobody believed in singularities when he was alive for this reason.
      According to Einstein's math, the mass at the center of our own galaxy must be dilated, in other words that mass is all around us because as the graph shows we are still connected to it.
      This is the explanation for the abnormally high rotation rates of stars in spiral galaxies (the reason for the theory of dark matter. The missing mass is dilated mass.

    What singularity? where? (A singularity is generally an artifact of the math model.)
    Imagine a neutron star accumulating matter. The gravitational gradient (force) is maximal at its surface, and decreases to zero at its center. Since the amount of matter involved is finite, the force cannot be infinite. Similarly, while the pressure at the neutron star's center may be very large (perhaps causing a phase-change "quark-matter"), the amount of matter involved is finite, so the pressure cannot be infinite. While the gravity gradient at the surface will cause some very interesting optics, I can see no reason why that could produce a singularity, especially given that quantum mechanics indicates a minimum distance metric. As a photon rises it should be red-shifted until its wave-length matches the horizon's dimension, but that is also a finite value.

    11:12 “there might be a relation between the gravitational constant and the speed of light and the mass and the radius of the universe” Both EM and gravity share the Inverse Square Laws, so this sounds logical as part of a 3D geometrical process! In observations on the international space station in near-zero gravity a candle flame naturally forms a sphere that is interacting with the environment relative to its two dimensional surface. Could this geometry be fundamental in forming three dimensional space and the passage of time? If the sphere was the size of the whole Universe the geometrical principle would remain the same, the surface area of the sphere is equal to the square c² of the radius of the sphere multiplied by 4π.

      Feynman, as I think did make contributions worthy of at least a joint Nobel prize in qed, his diagrams reflect a creative and an original work which had many applications. On the other hand, he, at least at most times, stayed with his philosophy of, ‘The first principle is not to fool yourself’. Maybe he is very famous because of his influence, especially for his communications through lectures and books. His overhyping is not upon his scientific work I assume, as it is of others in your series, but rather of a public popularity of him for his attitude and charisma. In his later life, he did make contributions worthy of another Nobel, as believed by some. May not put him in great but definitely not in overhyped. But a lively scientist larger than life.

    What’s wrong with larger black holes being less dense? It’s easy to see why this should be true. The more mass a thing has, the less dense it needs to be to have a particular strength of gravity. Hence Jupiter has over 2.5x the gravity of Earth while having less than a quarter of the density.
    And what’s wrong with the idea that the universe itself might be a black hole (or inside of one)? That would be fascinating and would lend support to Lee Smolin’s hypothesis of cosmic natural selection.
