The answer to all those question is the same no one knows and no one cares because it wouldn't matter because it has no meaning and no bearing.



At last! After much rambling – an answer!

“Does time have any significance if there is nothing to measure?”

“….no one knows….”

Thanks. The rest is very interesting, but irrelevant; however, to some extent it is the sort of thing I am looking for when I ask this kind of question. The more I can learn, the happier I am. smile

I still wonder if we are asking too much of time, even by asking if it exists as an entity separate from matter/energy.

There never was nothing.
