    It's been a long time since someone got a Nobel Prize in Physics for work that is essentially Mathematical Physics - Dirac, or maybe Wigner, may be the last ones previously. Good to see that an individual scientist still gets rewarded for his creative genius, and not just CEOs of big experimental groups.

      The vast majority of people have no interest in the subject. Probably because so few people actually understand what he is talking about. E.g. As soon as he starts talking of distance measured by clocks the average joe-public can't even grasp the concept, then adding light-cones etc and JP goes, 'wtf? I'm out'. Many people can quote such things as 'e=mc2' but they have no idea how to actually calculate with it or what it really means. Give them a gram and ask them to calculate the energy equivalent (and how many litres of water it could raise by 100-deg C) and you'll just get a blank stare. JP is too busy scratching its collective butt and stuffing its face etc to even want to exercise its brain. The very mention of 4 dimensional geometry is a non-starter for the greater majority of JP.

      just so you know, einstein denounced the very notion of black holes. he said his theory didn't allow for it. this is fact. i know these folks are way smarter than we common folk but dang. just once i would like to see a picture of an actual black hole. you would think in all the universe there would be at least one they could turn to as say there look, there it is, Now you can say beyond a shadow of a doubt that general relativity is accurate, but until then just remember, this is All theory. Einstien didn't allow for it and other great minds didn't either. as a prominent scientist said; you can do maths and come up with the scenario where an elephant can hang off a cliff swinging on a daisy.

      @@meostafford Einstein denounced a lot of the implications of his theories. To the point that later he struggled to change his theory especially for quantum mechanics. But its his correct theories that have been tried and tested.
      Wouldnt it have been nice for him if GR solved it all? Instead it opened more questions than answers, and they are all extremely weird and counterintuitive.
      Who knows though, its not all absolute so maybe given another century he would find a theory of everything that is different to QM and GR.
      Not saying some intuition wasnt the right direction, but in science we follow evidence, which auggests GR and Black holes. We even have a picture of one.

    I have a question or two? the backward "world line", the lower parts of the double cones, are also called the backward (in time) light cones. They define, how we see galaxies in our telescopes; the farther away, the longer the light is travelling on the mantle of this "cone" in 4_D. Plug in the still somewhat hypothetical effect of "cosmic expansion" into this 4_D diagram, and the mantle of this cone gets bent into a "belly" or water droplet_shape form! Because of this effect, we can see very far away galaxies, high Z_galaxies, in our best telescopes at an "enlarged" angle/visible diameter, than without that effect. is that "belly effect" valid for gravitational waves, too?
    2nd) cosmic-distance lightwaves are red-shifted; do gravitational waves get equally or differently red-shifted AND also get "belly-bent"?
    So, then? would GWs, primordial GWs (if they exist), from "behind" the Cosmic_Background_ Radiation, from behind the CMB, would they be "angular enlarged" and "red_shifted"?
    Could those giantly Large_LongWavelength_Gravitational_Waves "invisibly" transfer impulse and energy to matter/galaxies in our (cosmic) neighbourhood?
    3) the simple "Newtons Gravitational Constant" is now very well measured yet. in future a more precise "G" measurement has to be done in space.

    I think the singularity picture is wrong. It is possible that the universe was simply static for a long time before it started expanding. The problem at time = 0 disappears if you simply consider negative time, and look at the static picture for t < 0. It could even have been oscillating, that is, expanding and contracting for eternity before, never really reaching a singularity, which is abnormal.

    That's funny. Leave it to Dr. Penrose to shoot down, in 60 seconds, the visualization of a black hole presented in the movie Interstellar.
    Kip Thorne et al have spent literally decades studying black hole effects, and recently, several years trying to make sure their visualization models were correct. The idea being specifically to give an accurate visual impression of what a black hole would look like close up.
    According to Thorne, they DID have to make a minor change in the visualization in order to make Nolan, the director, happy. It had something to do with the IMAX version being TOO intense, and Nolan wanting to tone down some aspect of a particular shot.
    Thorne has given talks where he displays the original version, and my recollection is that it didn't substantially change the look of the thing...
    Anyway my point is Thorne taking years to try to get it right, and Penrose shooting it down in mere minutes. Even though his drawing isn't HIS idea of what it should be. It's based on computer simulations probably done on a PDP-11. With an 8-bit data bus... In 1978!
    Scientists don't always agree... :-) :-) :-)
    Finally! The first talk where a slide shows negatively curved space as a Pringle's potato chip!

    • @albat6538
      @albat6538 Před 7 lety +4

      It's because even the fastest moving object, the photon, travels at the boundary of the cone. So, in order to be outside the cone, an object needs to move faster than the speed of light. Which is impossible. It also implies that outside the light cone, for objects travelling faster than light, a time interval does not belong to R (the axis of real values). Instead, by Lorenz transformation, it will have an imaginary value: t'=i*a*, where a is a real-valued constant.

It was common sense to me that as a 'body' was following an orbit being treated as if that body was a slightly curved infinitely thin or 2 dimensional mass folowing it's correct orbit, but it obviously is not 2 dimensional hence would result in that body experiencing a slight internal tug of war...

    Roger, if you consult on the definition of electric charge in standard books on electromagnetism,you will eventually find( after some substitutions and mathematical techniques) that, Mass( in kilograms squared)= Charge squared( in Coulombs squared)x 10 to the power minus 7 divided by distance between two charges in meters. So, Newton's Law of gravity is actually equivalent to Coulomb's Law of electromagnetic attraction or repulsion. By the way, only Hawking said that gravity always attracts, never repels. Newton in fact said that gravity both attracts and repels( On the Shoulders of Giants (2002 edition) Page 1160).

    If light is a particle, in addition to a wave, wouldn't gravity effect it even if it were a force rather than a curvature of spacetime? When a beam of light is shot perpendicular to the horizontal path of travel of a uniformly moving frame, does it continue to move horizontally with the frame, as shown in illustrations of Einstein's light clock thought experiment? If so, it must be acting as a particle, because it's acting like a tossed up ball on a train. So we really don't know if gravity is a force or not, it certainly acts like a force.

    It’s a very interesting hypothesis, but I think he may have overplayed the see through to the previous aeon part. Depending on the place or those objects in the past, and our present, they may be too faint or have become casually disconnected and the theory could still be correct. If we evolved 15 billion years from now, we wouldn’t have the evidence of the microwave background which certainly limit our understanding.

      You can have different infinities in maths. So a smaller infinity could be bounded within a larger one, e.g. the infinity of real numbers is smaller than the infinity of complex numbers. Or, there could be infinite fractions between the real numbers 1 and 2, which could be contained (bounded) in the infinity of fractions contained between the real numbers 0 and 3.

      Physicist B.G. Sidharth points out, light has mass due to noncommutative spacetime (noncommutative phase).
      "Therefore, the underlying geometry behind the superluminal nature of a particle is simply the noncommutative geometry."
      And Professor B.G. Sidharth again:
      "Returning to the mass of the photon, it can be argued that this is a result of the non commutativity of spacetime at a micro scale."

  • @CACBCCCU
    @CACBCCCU Před 2 lety

    Tossing the lame eye prescription politics of forgetful brain-dulling bent spacetimes in general:
    If observed blueshift is an effect partly conforming to observer gravity not an effect conforming only to light source gravity, flipping the magnitude of an observed shift restores realism to remote gravity measurements, undoing the light channel's cumulative effects, also it conforms to supposing all changes to falling rates, and to frequency rates, must run together in the same direction. However, not taking shifts literally but instead taking them flipped inside out would disagree with the trampoline-type "matter stretches spacetime" lensing theory used to explain the paths of mass particles and light bending toward mass. Despite that flipping around frequency shifts would agree with a round mass compressing the closest space around it the most, just like it compresses another mass the most on its surface, the curved spacetime theory for flipped gravity shift remote inference-making (anti deSitter space) says mass must repel light and bits of matter in space. Ultimately, neither of the two complementary bent spacetime tropes is completely realistic.
    General Relativity basics for light: Mass media fun house holy sacrament: Special Relativity's Perfectly Flat Everlasting "c" bends everything for more simplicity:
    Using GR, you can measure distance with light by counting wavelengths of a known frequency (X wave-cycles/meter) and measure time with light by counting oscillations of a known frequency (Y wave-cycles/second). Supposing speed of light is constant, blue-shifted light's faster oscillation rate means time rate is faster, while a fixed count of its shorter wave cycles defines shorter meters. Faster seconds and shorter meters allow blue-shifted light to cover a constant number of meters per second. Red shift is handled similarly with the same result, namely a constant number of meters per second.
    Faster light is not the same as faster seconds or slower seconds: Don't stretch it in front of the class:
    When light (and space and time) is laterally compressed more when closer to a mass and compressed less when farther, what draws light toward mass faster than drawing it away? Answer is nothing, not even time reversal. When light (and space and time) is laterally stretched more when closer to a mass and less when farther, what draws light toward mass faster than drawing it away? Best answer GR is a model where stretchable space fabric gets pulled down by gravity pushing on top of it. When light is faster closer to mass and slower when further, what draws light toward mass faster than drawing it away? Answer is flat time, bent time, backward time, any kind of time.
    Believe it or not: Unbent time and unbent space also have the benefit of giving an easy accurate accounting of energy:
    Keeping wavelength constant while letting frequency vary means initially redshifted light realistically must be light initially slowed by decreased gravity. Same with a passing rumble-strip effect. Light frequency is independent of photon rate, meaning a constant-rate countable photon (or light pulse) source gives the only reliable light-based indicator for time rate. Heisenberg's uncertainty applied to light says a tight frequency source is a loose phase timing source, so atomic clock frequency means practically nothing about photon rate.
    Quiz: A green satellite looks blue from earth, green when you get up there. Eyes must've shrunk, and clock must be faster, shortened counts of light-waves now fit green. Thus: A) the light was blue until eyes shrank, B) the light started green and ended up blue, C) universal simultaneity is impossible, so keep time reliant on color, on frequency counts that must be frequently reset.

    This they should've known !
    All downward falling motion, including Newtons apple, begins when active rising gas molecules in motion as an ENERGY FLOW become trapped and motionless within the process of BONDING together making solid objects, which as solid objects they can only fall downward. This is scientificly known as the mechanism of GAS BONDING, which take on a state of solid mass blocking out its electrons motion, it's fire power, thus become ENERGY LOCK lifeless dead gas molecules, and falls downward in real time, following its Electrons Unlimited Potential Velocity at the speed of light connects with the earth ENERGY CONSERVATION SYSTEM SYSTEM activitys, it's surface electro magnetic field at quantum levels establishing a downward falling path for trapped ENERGY LOCK lifeless dead gas molecules/solid objects only.
    Equating the above fact with the physical universe, same as Einstein E = MC2 equates with the physical universe .
    E = ENERGY = MM = MOLECULE MOTION = Molecules in motion within star flames earth gases birds and balloons plains and rockets, even us humans rise from molecules in motion creating an ENERGY FLOW, the ruling force of the universe.
    M = MASS = GB = GAS BONDING = Gas Bonding take on a state of solid mass blocking out its electrons motion, it's fire power, thus becomes ENERGY LOCK lifeless dead gas molecules, and falls downward in real time.
    C2 = LIGHT SPEED = E = ELECTRONS = Electrons Unlimited Potential Velocity at the speed of light connects with the earth earth ENERGY SYSTEM CONSERVATION SYSTEM activitys, it's surface electro magnetic field at quantum levels establishing a downward falling path for trapped ENERGY LOCK lifeless dead gas molecules/solid objects only.
