The creation of all matter in the universe, as I am sure you have read a lot into is quite problematic, however the particle physics of it, favours a
hot big bang for a number of reasons. The possible holes in the theory are in the process of being tested at the neutrino beam facilities around the
This is, CP violation.
Particle physics says that, when you create matter from energy (gamma conversion) you must conserve certain quantum values, what these are physically
are unknown, however they do effect physics at many levels so we have good reason to believe of these quantum values as existing and the laws of
conservation being held (hey it works for absolutely everything observed so, its a pretty fair bet right?)
So from a gamma, you produce one unit of matter and one unit of anti matter. Essensially the problem we have is that, if this is what happened and
does happen during matter creation, then the universe should be either full of just energy (matter and antimatter annihilate to produce a gamma) or we
should see huge abundances of antimatter. So why dont we?
Well this is were CP violation steps in. At a very base level CP violation says that the couplings/interactions and decay rates of matter and anti
matter do not have to be the same, nore the decay paths... (ie if you get a bit of matter and it decays in 5 possible routes, then the antimatter
equivalent doesn't necessarily do a mirror 5 possible routes). It has been observed in the quark sector, and it can (depending on the model) produce
a good matter/antimatter asymmetry, but it has been a problem for a while that the actual asymmetry that this produces is not enough to fit in with
what we see today.
We need CP violation in the lepton sector also. We have seen hints of it in neutrino oscillation data, though nothing that sits well as super hard
evidence, signed and sealed.
From particle physics, this is the best I can explain without going though and copying textbooks full of mathematics and i am sure that is not what
you came here for.
Constant creation models I believe are problematic because the whole matter genesis and the 'removal' of antimatter from the universe requires high
matter densities for amplification of oscillation effects (oscillations in particle Eigen states...) There are a few good candidates for this to be
occurring at a constant rate, but these too are slightly problematic for a few reasons.
1) CRB - enormously energetic - source is unknown though a number of theories suggest plausible mechanisms, these result in creations of black holes,
these objects tend to hold matter nearby rather than distributing it, this causes problems for the structure of the universe we see today.
2) Explaining the CMB, needs either a hot big bang or some horrendously complicated mechanism to produce the perfect black body curve that exists in
its spectrum, bit issue for constant creation
3) Constant creation would suggest non-conservation of energy, and if not, then conversion from one to another. Any particles that spring into
existence must do so following the physical laws that we have observed to be true (at the very least) and such, if matter was being created at a
constant rate we would expect to see a smooth night sky of 511KeV gammas at the very least... because electron positron pairs would be constantly
produced smoothly throughout the universe.
It is a very very interesting question, and many interesting theories and answers are out there to be found. We don't understand everything, and for
some things we can only ponder and put together the best answers we can using the evidence we have. Keep seeking answers, to approach this how you
have done speaks worlds for your attitude, which i may say is the correct one and a breath of fresh air...
