Dark Matter is supposed to interact with gravity and electroweak forces. According to the usual timeline of the first minute after the Big Bang ( http://www.fact-index.com/t/ti/timeline_of_the_big_bang.html ), Matter and Antimatter formed after gravity and the the strong nuclear forces appeared (electroweak force act like the strong nuclear one) (10^-43 to 10^-33 second). The electroweak force appeared (as itself) during the annihilation of Matter and Antimatter (10-^33 to 10^-5).


If Dark Matter was created at the same time as Matter, the electroweak force should have acted like the strong nuclear force, so creating Matter. So it means that Dark Matter was created first, then created Matter and an excess of Dark Matter was left... This excess can only be, if some Dark Matter did not condensed into Matter. But how could it be if it possess an electroweak field acting like a strong nuclear field? And what created Antimatter? Dark Antimatter? If there was Dark Antimatter, where is it now? We should see remnants of it...

Is the momentum of electroweak field for a spinning particle of Matter and Antimatter not absolute but rather relative? If Dark Matter possessed, at its creation, a net positive momentum of the electroweak field,  there would have been a preferential momentum at the Matter-Antimatter creation process. This would explain the asymmetry of Matter vs Antimatter...


Maybe, there is Dark Antimatter with an absolute negative electroweak field momentum... Dark energy... But, in my opinion, Dark Energy should have appeared at time zero in order to start the Big Bang... What do you think?

I loose you right at the beginning on this.  In my book dark matter interacts only by gravity and not any of the other forces.

The reference you quote contains no mention of dark matter and concentrates only on the behaviour  of observable matter.  Also the events before the nucleosynthesis era (which is well modelled and fits with experimental evidence) are highly speculative at the moment.

Dark matter is supposed to interact with electroweak and gravity :

My point is where we can put Dark matter in the timeline...

I don't think i have the truth but it is so interesting in the possible consequences and there is surely some tracks leading to the truth...

Thank you for your comment, i was not clear at all. I have changed my text...

Wimps I agree by definition are weakly interacting but they are only one of the several possible particles that could form dark matter.  The article you quoted mentions others but is far from exhaustive.

I think the key point here is understanding dark matter in more depth, at present there is only a theoretical model to describe the interactions of dark matter but no real evidence exists in the lab or actual data as to the construct of dark matter hence all these underground particle detectors being invested in.

 Since the big bang theory has been formulated and calculated using various simulations upon how we believe certain things to behave then, for example we know protons and neutrons weren't th first particles to have formed based on our knowledge that protons consist of quarks and so on. This is all fair and well with particles and matter that we are familiar with, but in the terms of dark matter we don't even have a working knowledge today so backtracking the evolution of dark matter in the universe is next to impossible in my opinion... well with any accuracy. In terms of anti matter, I think they may have been two sides of the same coin and created roughly at the same time from the same parent forces and particles although thats just my point of view. In short it is a shame that we don't have a deeper understanding of dark matter since it makes up such a huge proportion of the known matter in the universe, this in turn hampers our attempts to understand the universe in general.

The fast inflation at the beginning of the Universe may have caused most Dark Matter (about 80%, according to observations) to not materialize into Matter and Antimatter. Maybe Dark Matter at the edge of the Universe has created less Matter and Antimatter than in the middle (much more than 80% Dark Matter left). What if, now, there is more Dark Matter at the edge of the Universe? Wouldn't it cause an accelerated expansion of the middle of the Universe? If it is not uniform, it can cause Dark Flows...

Some explanations about why there should be more Dark Matter and less Matter at the edge of the Universe.

During the first minute after the Big Bang (Matter is viewed as Baryonic Matter and includes Antimatter):

Hypothesis 1: In order to produce Matter (and Antimatter), the Universe needed a specific energy density and this process took some times. (do you have doubts?)

Hypothesis 2: Gravitational energy field was the first to appear. The energy density is related to temperature, volume and gravitational energy.

Hypothesis 3: The expanding Universe was spherical (if you prefer, it is an approximation) because gravitational energy was very dense.

Hypothesis 4: The total energy density at any specific time and space was not a constant but rather a function of 1/R^x (where x > 1). This is caused by the expansion of the Universe... The volume of a sphere is 4/3*π*R^3. You can see it as an explosion in space, the particle density is not uniform but it is a function of 1/R^x.

Hypothesis 5: Dark Matter does not possess a strong nuclear field and Matter does. They both possess gravitational and electroweak fields. According to the previous hypothesis, it means Matter needs a higher total energy density than Dark Matter to be produced. Therefore, there is more Dark Matter at the edge and more Matter in the middle of the Universe due to the energy density function.

Hypothesis 6: In the process of Matter creation, some gravitational energy is transferred into a strong nuclear field, thus lowering the gravitational field in the regions where more Matter has been created. If you don't believe in this hypothesis, you don't believe in a Unified field theory...

Independently of those hypothesis, Dark Matter interact only with gravity and the weak force, according to recent observations ( http://home.slac.stanford.edu/pressreleases/2006/20060821.htm ). It is thus, highly probable that most Dark Matter is going faster than Matter and only some of the Dark Matter was trapped by Matter (around galaxies)... Unfortunately, it should be too far away by now to be observed directly... But how can we observe it?  [:0]
