The Feynman Diagrams for the Big Bang

The Feynman Diagrams for the Big Bang

It is sometimes said that the moment of the Big Bang is beyond the scope of science. I disagree with that statement. If the Big Bang is within the realms of Quantum Field Theory then we should be able to draw Feynman diagrams starting from the Big Bang singularity.

These Feynman diagrams are very special because they necessarily have an infinite world number of lines drawn out of the point T=0. However, it turns out that when transforming the description to cosmological time, this simply means that an infinite number of particles are created at the Big Bang forming a Poisson distribution.

The most likely candidate for the identity of these infinite number of particles are gravitons, as there is no limit to the number of gravitons that can be emitted in a single interaction. The other alternative is that we must simply sum over every possible configuration of particles.

Vortex Solution to Navier Stokes Equations

Image
This is a solution I found to the Navier Stokes equations . It uses the flow lines of the Hopf Fibration (which is basically just a way of covering the entire 3D space in circles). The flow lines can be seen in this image below: You can see my paper here. Solution to Navier-Stokes equation . Unfortunately I won't get a million pounds for winning the Clay Millennium prize because this is a compressible not incompressible solution. :( Oh, well. Nice try! I think it's pretty nice anyway. :) Also it uses the nice identity: which paramaterizes the Pythagorean quadruples!

Conjugate of Lie Algebra

Conjugate of Lie Algebra A little article noting the similarities between momentum conservation (continuous) and charge conservation (discrete). We all know that the conjugate coordinate to position is momentum . Thus a term such as  ∫O(-k)O(-q)O(k+q)dk 4 dq 4 = ∫O'(x)O'(x)O'(x)dx 4 But a lie group given by it's root vectors (charges) also has a similar form which looks a lot like momentum: O {-A} O {-B} O {A+B} + (A n )O {A} O {-A} O n So we should be able to find conjugate variables to the root vectors. So we can write the above as: O' C O' C O' C The O' C  being linear combinations of the Os. In the case of E 8 , the {A} are 8 dimensional unit vectors. One difficulty are the neutral particles, O n  , which seemingly have no equivalent in the momentum picture. Such a term would look like:  ∫O(k)O(-k)kμAμ(0)dk 4 =  ∫O(x)Bμ∂μO(x)dx 4   which is not Lorenz invariant.... [ unless O(x) were spinors and Bμ were Dirac matrices?? B
