Anti matter and -t

[Moontanman]

Does anti matter have a negative time direction? Is it possible that at the beginning matter and antimatter took different time directions and ended up with two universes, one going +t and one going -t ? In both universes time would seem the same as it does in ours but relative to each other they would be going in different t directions. Would this account for where the anti matter went? In my idea I see our t direction as being mostly matter with very little anti matter being formed, in the t direction for anti matter i see mostly anti matter and very little matter. Has this possibility ever been looked at?

No idea if it has ever been looked at, but it definitely sounds interesting. Wasn't there an explainable symmetry breaking which explains why there is so little anti-matter?

Also, your idea might not sound as strange as it sounds at first, if you consider that in Feynman diagrams a positron for example is just an electron travelling back in time...

I've been rolling the idea around in the sump of my mind for a long time, it just seems so pleasing to my sense of balance

One problem I see with the OP hypothesis (that is, that matter moves with positive time and antimatter with negative time) is that our positive time direction does have lots of antimatter--it is just bound within matter--such as within the matter proton are various forms of pions--see this link:

Pion - Wikipedia, the free encyclopedia

 

So, I think it not so simple that all matter went with positive time direction and antimatter with negative time direction since big bang.

 

Here is another thought. Perhaps at start (big bang), matter associated with space-time positive gravity and antimatter associated with space-time negative gravity. So, consider the pion with [u + d^] quark structure, where ^ =antimatter. The quark is associated with positive gravity dimension and the [d^] quark with negative gravity dimension, but the entanglement between the two coherent yet remote elementary particles is within a third dimension of space-time that is not directly detectable to us. What this means is that all the so-called 'missing' antimatter might be present right on the tip of our nose and we never know it because it exists within a hidden third dimension of reality where matter and antimatter coexist as a quantum superposition. Just a thought in response to an interesting OP question.

Wow, the speculations get more and more interesting! But I think you may have got a point there rade in as to why the -t option for anti-matter might not really be an option...

Another idea is that the reason for the anti universe would be the same as reason behind the production of something from nothing if when the come back together they still equal zero? Like virtual particles in the quantum foam. So the big bang has to have a -t counterpart so something from nothing can still be nothing. Possibly a singularity that produced two universes from nothing? Oh well it keeps getting worse as I try to justify it, just an idea I guess.
