Hi Saibal,
Hi Bruno,
Patric has already explained Barbour's position (I didn't read his
book).
Separating space from time is not very natural...
I agree. If only because of special relativity. But the very notion of
space is quite complex. It is a reason why I find loop gravity more

This reminds me of a good paper by Carlo Rovelli

Hi Brent,
There's no doubt that my imagination is not up to the task of coming up
with reasonable explanations of all that I see. I could never imagine

infinite space, the multiverse, and Günter Wächtershäuser's
Hal,
It is possible that miracles will be as uncommon and surprising in your
QTI-guaranteed future as they seem to be today. If you live to 1000,
unlikely as it sounds at present, shouldn't you expect it to happen in the
*least* unlikely way? This may involve advances in medicine initially,

Remember that the chain of events that must lead you to be 1000 years

I think that your example below was helpful to clarify the disagreement.

would not be different from the selective
