Firstly let me clarify something..
The so called Time-Space term coined by Einstein for describing our universe is in fact a rather misleading term...
You see Time is only our concept of change.
If nothing changes there is no frame to measure time...
The universe as you or I see it is in three distinct states... Past / Present / Future...
But in true reality there is only Now.... why do we remember past events and not future events??
The reason is that the past doesn't exist it is only our memory of the configuration of matter of the universe...
Let me try and explain...
The universe is a sea of virtual particles popping in and out of existence all the time... They are neither real or not real they are just the
unlimited possibilities of the universe...
For example. you are made of matter and matter is made of smaller and smaller particles that have just as much chance of existing in you as they do
in the centre of a star billions of light years away...
What we see as time is only the change in the universes configuration of its matter.
Sounds complicated but it's really not...
In answer to your question about an Anti-universe... well M-Theory (look it up under string and super string theory) suggests that there are multiple
dimensions within our reality, some are space dimensions that we cannot perceive or realise. so it is possible that an ANTI-Universe can exist within
these other spatial dimensions...
However.... M Theory also suggests that our universe could be part of a much larger universe that is made up of other universes and we are only a
small bubble in an ocean of possibilities....
Personally I like to think that we are all in control of our own reality. That is we can realise our potential we could actually physically shape our
own reality.... But that's talking Metaphysics and nothing can be proven there except for the capacity for man's creative thoughts
Anyway.. I'm going to creatively seek my lunch now...
