An Idea

[Profpat]

I like the idea of an anti-matter parallel universe. Like the symbol of the TAO. This would instill CPT symmetry if you viewed the two universes as really only one.

I imagine a white hole would look like a big bang.

Given the neat mathematical trick of writing out a de Sitter solution for General Relativity and modeling a black hole in it, if you then write an anti-de Sitter solution, black holes appear as expanding clouds of energetic particles.

Can you say:

" I'm a sheet slitter, I slit sheets "

5 X really fast.

Every time a black hole in born in this Universe a white hole is born in the antimatter Universe. If yes, I would imagine the converse to be also true. Now that means that either matter converts to antimatter inside the process or we get a whole lot of antimatter direct from the other side.

You can just model this Universe as time-reversed to get an anti-Universe.

Hi Dipayankar;

I guess there would be big explosions when anti-matter mixed with matter. Maybe they change their spin so a particle of matter before entering the anti-matter universe, changes it's spin to an anti-spin?

Remember the reversal of time orientation.

Anti-matter would "face" the other pole in time.

Hi Max;

Do you mean when I look at a clock in the mirror. My clock is going clockwise but the one in the mirror is going counter-clockwise. What is the time pole Max?

Best,

Pat

The far ends of Time (assuming it isn't a loop, either way you could simply say the direction you were traversing the loop, but I digress), we face Timelike Infinity. Anti-matter would face the "Singularity".

That's interesting Max, I never thought of it that way. Their universe would be contracting towards the singularity and ours is expanding away from the singularity, towards infinity.
