Thanks linda, i'll check it out.

I'm starting to get that idea. I just thought they would have gotten a little farther.

Has anyone heard/know anything about a book called 'Three Roads to Quantum Gravity'? (by Lee Smolin)

Yup. It's on my shelf, still unread, because I was going to review it but had other things to do first (and this was two years ago).

Lee Smolin is an excellent writer, though.

hahaha,...niice

Just bought it,
we'll see wat i can get out of it.

The black hole would produce the same energy jets, from the poles, originating from the matter in the centre.

Important note is that most models have black holes as roting. Same as for neutron
star or figure skater, as the radius of rotation shrinks, the rotation goes faster. This
force infalling material to accrete into a disk. Yes, jets do form at the poles (X rays).
From what I understand, we're not all sure why.

Configured how ? All energy we know so far is configured into something Fermions with
mass or Bosons without (Z particle with exception has mass).

It is still somewhat of a controversy, I think. Though I have slightly different facts. It is
that conventional wisdom has settled on 13.7 billion years since the big bang. However,
some globular clusters have been found to be more than 14 billion. Of course at the
time I read this it was thought that the universe was 12 billion so maybe this is now just
noise in the data.

Yes, excellent book. After reading it, I started looking into Topos Theory and Loop
Quantum Gravity and restudying Twistor Theory by Roger Penrose.
