Dear Paul, Hitoshi, Stephen, Matti and Others,

Paul, these are responses to my last post of your words. If birds of
a feather come together, then he "Problem of Time" may be
solved to the satisfaction of all. Matti has some more questions


Dear Bill,

Thank you for your forwarding Dr. Marmet's interesting message. His
position that he assumes only 3 dimension as a basis for his explanation of
physical observations would agree with my view. We would be happy if he
would join us. If he agrees and let us know his address which he will use
at this time list, I will register him as a member.

Best wishes,

Alternative interpretation is that our conscious experience gives
information about small spacetime volume such that its temporal extension
is very short, say of order second as neurophysiologist argue.

The undeniable success of Special and General Relativities leave at least
to me only single option: geometric spacetime is real.
If one agrees on this one is already forced to admit that our subjective
time and geometric time are different things and the task is
to construct theory of consciousness explaining how and why the contents
of our conscious experiences are localized in time and space.

Elementary particle physics relies crucially on Poincare invariance,
which is 4-dimensional symmetry. For instance, there would be not concept
of energy without 4-dimensional Poincare invariance. One would also lose
the concept of antiparticle: 3-dimensional spinors would represent
only fermions but not antifermions. I do not know how to reproduce
the predictions of gauge theories, in particular electrodynamics in
3-dimensional context: since Maxwell action is essentially 4-dimensional
concept (for instance, fine structure constant would have dimension of
length in 3-dimensions). Can you reproduce elementary particle physics in
3-dimensional world?

Dear Bill,

    I have been reading more of Dr. Marmet's on-line book and I must say
that I really like the way he thinks! I did not mean to disparage him in
my criticism of his philosophical stance, it is just that I did not
understand him well enough. I hope he could add his wisdom to our
discussion group!

Kindest regards,
