I imagine it must...Could we have dark anti-matter in our universe that doesn't interact with ordinary matter?
Would this example say Baryon asymmetry?

There are anti neutrinos and anti neutrons.cristo said:Dark matter doesn't interact by the electromagnetic force, thus is not charged. Hence there is no such thing as dark anti matter.
There are two main theories, cold dark matter is ordinary stuff ( gas, dust, rocks) that is too cold and dark to see but still has a gravitational effect, because we can model the formation rate of material from the bigbang quite well it doesn;t look like there could be enough of this.We don't know what dark matter is made of right?
Hot dark matter (or non-baryonic) is unknown particles that don't have electromagnetic effects so don't give off light. This looks more likely, but there is always a danger of coming up with a solution that involves being able to 'make up' whatever properties you like for your solution.

Perhaps I phrased it badly - dark matter doesn't generate light and doesn't seem to effect the properties of light passing through/near it, so we cannot see it directly - hence dark.

wildwill said:they found positrons by using the Earth's magnetic field and looking at the aura borialus
so anti
matter could exist
wildwill said:wouldnt the antiparticle be white matter
or photons
wildwill said:oh okay so would black wholes be dark mater
Do you think its possible that matter is created from the interaction between Dark matter and Dark antimatter? Could this be an explanation for the "Big Bang" expansion of the Universe?coronzon93 said:My thoughts are that there is Matter/Antimatter and yes, Dark Matter/Dark Antimatter. My thought on that is that Dark matter has its own set of quarks and bosons. So there would be Dark Leptons, Dark Mesons, Dark Baryons, Dark Bimesons, Dark Barymesons, Dark Trimesons and Dark Dibaryons. Matter/Antimatter DIRECTLY interacts with Matter/Antimatter. Dark Matter/Dark Antimatter DIRECTLY interacts with Dark Matter/Dark Antimatter. My own (strongly disputable) theory on annihilation is that when a particle interacts with its antiparticle, the annihilation yields a decay series of particles of the opposing kind. e.g. a Proton interacts with an Antiproton, the Matter yield is nothing, but Dark Matter yield occurs (not a Dark Proton and Dark Antiproton, but can't rule out the possiblity).
StevenJParkes said:Hypothetically. On the assumption that dark antimatter exists. If it does and if we could trap it, would it then be possible to use it as an energy source by making it interact with dark matter? How destructive could that be? and what other consequences might there be?
StevenJParkes said:The other hypothetical question that led to the above one is as follows: "Is it possible that antimatter is the source of the limit to the speed of light?
StevenJParkes said:My thoughts regarding the above questions relate to finding a method of exceeding the speed of light for the sake of space travel some time in the future.

This is embarrassing. I meant. Is it possible that dark matter limits the speed of light. It appears to have gravitational effects.StevenJParkes said:The other hypothetical question that led to the above one is as follows: "Is it possible that antimatter is the source of the limit to the speed of light?
