I read his book a year or so ago, so may be a bit hazy, but:
Pour Bruno: he definitely does not want to talk about space-time capsules.
Partly this is motivated by his metaphysical ideas about time, partly by
the technicalities of the 3+1 (i.e. space+time, not persons!) approach to

Hi All:
In my view life is a component of the fastest path to heat death
(equilibrium) in universes that have suitable thermodynamics. Thus there
would be a built in pressure for such universes to contain life. Further
I like Stephen Gould's idea that complex life arises because evolution

This scenario that you are discussing reminds me
of this interview with Julian Barbour where
he proposes that time is an illusion.
This reminds me of a good paper by Carlo Rovelli
(about quantum gravity, GR, space-time, etc.)

Hi Bruno,
Patric has already explained Barbour's position (I didn't read his book).
Separating space from time is not very natural...
Perhaps one can use a similar method as presented here:
http://arxiv.org/abs/math-ph/0008018
to derive the notion of space-time as a first person phenomena.
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
relativity, quantum mechanics, black holes, singularities, the Big Bang,
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,
Hi Norman,
I entirely agree with Julian Barbour. A fundamental notion of
time would act as a pointer indicating what is real (things that are happening
now) and what was real and what will be real. Most of us here on the everything
list believe that in a certain sense 'everything exists',

Dear Stephen,
With your permission, I answer an offlist post you sended to me and some others,
Bruno, you claim that I assume a physical world. While I would agree with that claim to some degree, it misses the point that I am trying to make, just as Lee's interpretation of my idea as being
