So what is the basis for expecting equal amounts of matter and antimatter? How is it in conflict with this simple simulation?Īs requested in the comments I modified the simulation to allow different initial number of particles and the probability of generating each particle. However, I do not see why the qualitative result of a dominant particle 'species' would not be expected to hold in general. Obviously this is a simplified 1d model where any generated anti-matter is immediately annihilated by a corresponding particle of matter, etc. Here is a snapshot of the results, where the black line is the number of 'type 0' particles and the red line is the number of 'type 1' particles: Plot(res, ylim = range(res), type = 'l', lwd = 3, panel.first = grid()) # Save the results and plot them if 'i' is a multiple of 1000 # Otherwise increase the number of antimatter particles by one # If a matter particle exists, then annihilate it with the new antimatter particle. #Otherwise increase the number of matter particles by one # If an antimatter particle exists, then annihilate it with the new matter particle. # Generate a new particle with 50/50 chance of matter/antimatter The simulation (written in R) is here: # Run the simulation for 1 million steps and initialize output matrix In this simulation both particles are created, but one gets sucked So I simulated a scenario with two types of particles that are created in a 50/50 ratio from hawking radiation, and always annihilate each other if possible. Will form from the vacuum, and one will tunnel outside the event Is a quantum tunnelling effect, whereby particle–antiparticle pairs To lose mass, and, to an outside observer, it would appear that theīlack hole has just emitted a particle.

In order to preserve total energy, the particle that fell One of the pair falls into the black hole while the otherĮscapes.

My understanding is the early universe was a very 'hot' (ie energy dense) environment.
