    We can be grateful for great minds the world over, such as Dr Wadia, that leads us to understanding. A question that plagued most of our minds about gravity... was how could it attract everything regardless of an object's properties?... Magnetism works on certain types of metals but gravity, on the other hand, works on everything in the universe, or so it seems. In explaining gravity, Einstein showed us that space and time are a real thing... with physical properties... and now, string-theory may be an explanation of exactly what those properties are.... Pretty exciting stuff really.

    If space-time is granular/fragmented, then there has to be some kind of bond between the grains/fragments to hold it all together. And if those bonds are also granular/fragmented, then there must be more "gluons" to hold those "gluons" together, ad-infinitum. There will come a point when you'll just have to admit that infinity/smoothness exists in there somewhere. Everybody keeps saying that "nothing" cannot produce "something". Therefore, there must be something there to make it "smooth". And don't compare it to pixels on your screen.

    What ever is going on in space time is determined by the AREA encompassing it.
    This area is growing proportionally to the amount of information that goes 'in' to the volume. Therefore there must be some granularity in the makeup of spacetime.
    This holographic like feature is the weirdest thing ever.

    The idea emerged from the extension of the Newtonian gravity theory is that the Newtonian gravity is naturally a gauged quite 496 dimensional E8 x E8 mathematical object in 9 dimensional isotropic flat space superposed to 4 dimensional isotropic flat temporal space leading to (9 + 4) - dimensional supergravity. It means that the gravity makes the job regarding the reduction of dimensions and the creation of supersymmetry. It also means we live in 9 dimensional space superposed to 4 dimensional temporal space. But the space dimensions as well as the time dimensions are equivalent to each other because of the isotropy of the space and the time. The problems related to the Newtonian gravity at the galactic and the extra galactic scales are solved with the extension of the Newtonian gravity. It is then expected from the extension of the Newtonian gravity that the observable universe adheres to a 7 layered Multiverse gathering quite 496 universes of the same mass and the same size as the observable universe.

      He explained the black part but not the hole part. But he didn't avoid the subject as he said he wouldn't talk about the singularity. Because his point was to introduce the event horizon to make his later point, not to talk specifically about black holes.

    • @MightyZeus
      @MightyZeus 8 лет назад

      +Just Another Atheist The point made is that there is no force of gravity but a big ball such as sun kept in the center of a trampoline that creates a depth in the space-time fabric around which the planets revolve and rotate.

    • @sunnyboynfs
      @sunnyboynfs 8 лет назад

      Mighty Zeus High mass can create warp in spacetime but what is pulling the low mass object towards high mass??

    • @MightyZeus
      @MightyZeus 8 лет назад

      Just Another Atheist For that you have to cover the whole setup within the warp i.e, there is no escape for the object but to go near the center. The thing here is the rotation of the objects around a greater mass will ultimately make them to collide but it will take a lot of time. I think since big bang is possibly true considering expansion of the universe as we see. The death of the universe would be the collision of everything at the center of a greater mass since there is no escape.

    • @sunnyboynfs
      @sunnyboynfs 8 лет назад

      Mighty Zeus Big bang theory says universe will expand infinitely and die in big freeze.. Since there is nothing outside universe and that nothing is infinite, universe will expand infinitely..

    • @MightyZeus
      @MightyZeus 8 лет назад

      Just Another Atheist You yourself just said that nothing is infinite then how will universe expand infinitely? (maybe u meant nothing is finite).
      You should check out string theory though it predicts using mathematical equations that there are multiple universes. It has an equation for wormholes and black holes too which possibly has the best use for connecting multi universes and dimensions. So, you can't say that there is nothing beyond our universe. The thing is atom is not the smallest element anymore and our universe is not the biggest thing out there.

    There are problems with our current (public) understanding of gravity, issues that bring into question the accuracy of GR.
    At Lockheed-Martin, they repeated Galileo's experiment with one difference. They took two rare earth magnets and bolted them together with north poles facing each other and placed the bolted magnets together in one box. They dropped it and an identical box at the same time. The one with the magnets in it landed AFTER the other box did. It suggests gravity and electromagnetism are connected. Which implies gravity is not curved space time. This was Tesla's contention, that space has no properties.
    Two entangled particles affect each other instantaneously - contrary to what this worshipper of Einstein states.
    Newton's laws and both SR and GR have problems. The Electric Universe model is a better way of explaining how the universe works. And if you use Maxwell's original equations, written in quaternions, rather than Heaviside's rewriting of them in Vector Calculus, you restore the Scalar component of light and will see that faster than light power and information transmission is indeed possible, contradicting a fundamental tenet of Special Relativity.
    Had we continued down the path Tesla followed we would have antigravity craft and travel to nearby stars. There is an indication that we have Top Secret projects at places like Skunkworks that use this alternate physics. Former head of Skunkworks, Ben Rich, said that we now have the technology to take ET home. He also said anything you saw on Star Trek we can already do. Both statements imply faster than light travel.
    Sorry Dr. Wadia.

    • @zacharycardenas7308
      @zacharycardenas7308 6 лет назад

      Jeffrey Stewart the problem with your point is that the universe isn’t “electric” because QFT is a proven theory and that implies that maxwells understanding of electromagnetism as waves is incorrect. We have also proven that empty space does in fact have properties. For example, if you have a complete vacuum (0 particles/m^3), virtual particles will come in and out of existence, this is because space itself is a thing, it has energy. Also, we know space time curves because we can prove it. For example, your gps on your phone will never be able to work accurately without accounting for the curvature of the space time around the earth.

    • @zacharycardenas7308
      @zacharycardenas7308 6 лет назад

      Jeffrey Stewart however, we also know that general relativity is not the correct picture because it is incompatible with qft for (maybe) obvious reasons. That is one of the main incentives in the search of the theory of quantum gravity. The universe is broken up into ‘bits’ which is in fact quite amazing!

    • @kensandale243
      @kensandale243 5 лет назад

      "The one with the magnets in it landed AFTER the other box did. It suggests gravity and electromagnetism are connected. Which implies gravity is not curved space time. "
      No, it does not imply that at all. It implies that what you think curvature is, is not what it is. I suspect you learned your Relativity from cartoons, with "curves" signifying "curvature".
      It is not reasonable to expect that if you add electromagnetic forces into the picture that these electromagnetic forces will act as forces in addition to gravitational forces. Duh.
      "Had we continued down the path Tesla followed we would have antigravity craft and travel to nearby stars"
      Nutcase.
