Subject: No gravity / no dark matter
Hello,
What do you guys think of this?

It's a respectable theory, but Verlinde needs to work out some
testable
consequences.
I was bored in an airport the other day and bought "The Grand Design"
by Hawking. He talks about his "model realism" philosophical stance --
the idea that anything goes modelwise, as long as it fits the
observable data. I like the idea, somehow. I know wonder if demanding
one true model is not confusing the map with the territory.
That can be proved to not exist, unless he assumes a strong form of
non-mechanism. We can't really do that already for arithmetic.
On the other hand, he also starts the book by explaining how
philosophy is dead,
Sure, and theology too. (sarcasm).
and how more or less theoretical physics
progressively makes all other fields of inquiry obsolete.
That is just physicalism. It just can't work. This shows how big is
the non understanding of logic by physicists. We knew that since
Penrose.
But it is also wrong, by simple confusion of level of explanation. If
we did the same error in "modern theology", it would be like saying
that the fundamental science (making all the other obsolete) is Number
theory. But with just logic, we know that the inside or internal view
of arithmetic by machine/number is NOT reducible to the ontological
theory chosen. With such type of error, I can understand why
physicists cannot swallow the consequence of mechanism, given that the
whole of fundamental physics would be made obsolete. Of course that is
not the case, and, on the contrary, the correct theory of everything
justifies a non reductionist view of reality. In particular, physics
(and theology) is theory-independent, and this saves most fielf of
inquiry from reductionism.
Hmm... My favorite book by Hawking is his selected paper: 'God create
the integers".
It reminded me of this cartoon (with my apologies in advance to all
the physicists in the room):
http://www.smbc-comics.com/?id=2556
Physicists confuse physics and metaphysics, by not seeing that
Aristotelianism is incompatible with Mechanism, and by confusing
mechanism and materialism. Yes, that happens often for fundamental
researcher often after retirement, except for philosophers, which
confuses theology with Aristotelian theology. René Thom explained well
that physicists confuse the notion of explanation and prediction.
Physicists are good in prediction, but naive about explanation.
Physicalism *is¨a form of creationism. They take the statement that
"there is a physical universe" as an explanation of why there is a
physical universe. They replace "God made it", by "it exists", but
that is not better.

There are several theories being pursued in which space or
spacetime are phenomena emergent from entanglement of quantum
fields. They
can be traced back to a proposal by Sakharov in the '50s.
