anyone who IS intelligent should read "The Last 3 Minutes" by Paul Davies.
many books have been written about the first 3 minutes of the universe, but this explores just about every possible scenario for the last 3. it seems a very bleak outlook whatever happens.
there is a very disturbing piece about "positive vacuums". very small chaps that appear (in theory) spontaneously, but contain so much energy that should one appear it would annihilate the universe in less than a trillionth of a second.
and now for the REALLY intelligent bit.
scientists at an american university are actually TRYING TO CREATE one.
you couldnt make it up.

a parting shot before bed.
every cubic centimetre of the so called vacuum of space contains a billion billion neutrinos.

I was going to write something here , but iv'e been reading the posts and it's far too intelligent for me, i'll have to go back to the NOWT thread..

jimmy, i agree. superrod spoilt it by actually saying something intelligent!!! back to nowt!

Driver, why has you got your eyes shut? What ARE you doing with your right hand?

Bosley, The question has to be : How did you know he could suck his....ermm.... and Did he prove it by demonstration?
Just curious

plantec, he used to demonstrate his party trick in the music room, churches, classrooms, pretty much anywhere whenever someone wanted to see it.

Re vacuums. Presumably a vacuum is only a vacuum if it is empty, devoid of matter (wave-particle duality debate aside), thus a vacuum cannot contain a billion billion neutrinos, can it?

This would violate the uncertainty principle by allowing us to give an exact value for both the speed (zero) and position (also zero) of the vacuum. In order to avoid violation of the principle we must allow for quantum uncertainties and therefore apply a non zero value to these values!!! It has been suggested that a vacuum is actually a seething mass of particles popping into and out of existence very rapidly, by annihalating with their opposite number. This theory has given much credence to superstring theory by suggesting these particles originate in one of the 7 extra dimensions required by string theory.
Phew, I'm glad I got that off my chest!!!

there was nothing. then there was a big bang. a couple of millenia later there was this thread. the circle is complete.

thanks alan
As Werner Heisenberg was not my favourite physicist (politics included) shall we dispense we all the delta p.delta h and E(psi) = H(psi) + nonsense crap. Eigenfunctions - smeigenfunctions. More likely to be bowel functions! String and superstring theories are more fudges dreamed up by mathematicians justifying their
grants and massaging their egos.
There, rant over

ps it is the language that is the problem. We tend to use and abuse words and notations which have become accepted in daily use when we should be much more specific.
Rant over (again)

Sorry meant to say Delta P.Delta x - not h (been a long weekend!)
