    Thanks 🙂 1. Super Symmetry is particle persistence in our Universe. V/c==ºC (Lorenz Gamma) The C scale is balanced in our Universe. 1c==1c^3==1c^2 is the same as +300,000,000m/s==+1ºC==+1photon So no "anti particle" is required to create matter. 2. The Big Bang Description you are using is a distance from the bang our Universe is possible, not an amount of time. Distance is the only moderator of energy. So what is particle "stability" actually doing in the Higgs field i.e What is happening in vacuum space to cause a particle to become stable and exhibit polarised "weight". Here's another contradiction for you ;-) We have proven that velocity time dilates with temperature. Yet we have particles of 300,000,000+ degrees Celsius traveling at the speed of light. The only answer is the raw "particle" is a whole in space and the hole is bouncing around at the speed of light. Welcome to "Skin Theory" **Bernhard** PS. The big bang is still with us and it is 12Planque wide, compressed with temperature into another "Dimension". Space is the Zero ºC , plasma output of the Big Bang, i.e. The Higgs Field. Great Lecture Thanks Again.

    I agree with Professor Kerr...(particularly minute 7:30 of this video)...Singularities was an interesting CONJECTURE ... but I think INVERSION physics (Shown at the Surrey 2014 math conference) places Singularity to an almost part of another 'Flat-earth-zone item' ...(the balance is , in my opinion, is seriously flawed, ....(before, minute 37 etc, etc, etc!) ... again, interesting lecture... also I think Edward Teller's video about attending an Einstein lecture will help guide aspiring physics majors into an accurate perspective to 'Einstein's later General Relativity' - which is dramatically different from Einstein's pre-1915 discoveries of Special Relativity - I am afraid that too many in academia are unaware of this reality ....

    This is soooo good. But why oh why does Turok not yet recognize there are no "complex numbers"? It's all the even subalgebra of a higher Clifford geometric algebra. So there is always a _real_ 4D spacetime algebra interpretation for all the "imaginaries" in QM. Typically either rotation symmetry (spacelike bivectors), or Lorentz symmetry (timelike bivectors), or conformal symmetry (the pseudoscalar). To get a chiral standard Model you need complex Lie groups, but that's just saying the scalar+bivector algebra is inequivalent to the vector and trivector algebra (which are not closed sub-algebras).

    This webinar is outdated. JWST showed us that Einstein's equations do not describe the Universe. In other words, galaxies' angular size is consistent with Euclidean Space and follows the Tolman Test. Interpretation of angular sizes using L-CDM or Einstein's equations leads to absurd conclusions (galaxies with a surface brightness 600 times larger than the brightest galaxy in our neighborhood. So, Einstein's equations do not describe Universe. Universe description does not require Dark Energy or Dark Matter. Higgs's mechanism for inertia creation is also useless. The description of Electromagnetism (in the Lagrangian on the Feynman path integral) is wrong. It does not consider expansion. Gravitation is also wrong since it does not include epoch dependence. So, everything is wrong. I would add to that the fact that HU already explained other phenomena without the need for Dark Matter, so the Lagrangian is wrong.

    Dr. Turok said that LIGOS would never succeed in detecting gravity waves. What are his thoughts now after LIGOS successfully detected gravity waves emitted from two colliding neutron stars?

    • @schmetterling4477
      @schmetterling4477 Год назад

      It's called LIGO, not LIGOS. What Turok said was that he doesn't think that PRIMORDIAL gravitational waves are detectable. That's not all gravitational waves, but only those that were generated by small inhomogeneities in the early phases of the big bang. May I suggest that you pay better attention next time when you are reading the science news?

    Gerard, luister nou even. Why do we keep talking about 'quantum gravity'? We define 'gravity' as the contraction of spacetime (caused by the presence or more correctly, the SPEED of mass). If so then obviously a grid that is NOT governed by spacetime, cannot have gravity since there is no spacetime grid to contract. So then why do you think that the subatomic quantum realm (e.g. the area between an atom's nucleus and outer electron orbit) is governed by spacetime to begin with? Have we EVER seen a motion in this area consistent with spacetime as the the grid? If not, then accept that in the quantum world the grid is NOT defined by spacetime, hence there can be no contraction of spacetime, hence no gravity. Simple.

    To imagine white holes exist as macro objects is to misunderstand the manifold. Black holes are artifact of gravity which gathers towards unity/singularity. White holes, themselves, are diffuse. Singular points of emergent neutrons are each lowest energy point of space to fill the gap in manifold created by that same neutron crossing/contacting event horizon. Neutron decay cosmology. Inevitable?
