Does time flow if there are no humans there to measure it? ...hmmm...
I guess its one of those questions like...
"How do women talk on a mobile phone, apply make up and drive a car all at once"...
Can information flow between two time periods? May be...
So What you are saying is no-one has a clue?
I think it is an efect that will end when matter doesnt exist anymore...
Maybe we can just ask 'WHAT IS TIME?
This dimension is different as we can only travel through it in one direction, when we pass one point, we cannot get back to that point again in the time axis.However, time is treated differently than the spatial dimensions.
