I have always had this suspicion that black holes create galaxies, they collect material in a 3D vortex and at a point of critical internal mass, they eject part of this volume to create a galaxey, they also retain a great deal of mass. Making the Universe an organistic regeneration system. Can anyone advise.

But this doesn't explain the big bang.

No matter can escape from inside a black hole, so I can't see how a black hole could create a galaxy.

On the other hand, there are probably one or more black holes at the centre of most galaxies.

There may have been several little bangs in fact one for every galaxy, waves tend to merge together, this echo from the big bang is interesting suggesting that there is an end to our cosmos where it bounced off and rebounded around our Universe, waves tend to join and harmonise?

But this doesn't explain the big bang.

Sadly at present there is no confirmed proof of the big bag, I wonder what would have cause the splintering of such a large mass presumably global and containing all the matter in the Universe, but not leaving large chunks millions of miles long in space, I am sure there would have been these pieces, to smash such a mass by one event seems to bend logic. The law and principle of the cosmos seems to evolve something, not create from a sudden voilent event, hence my rational would believe everything is a copy of these Laws and Principles. All life is modeled on the order of the cosmos.

The rival-theory to String Theory - Loop Quantum Gravity - suggests that the big bang is actually "a big bounce" - Scientific American Vol 290 pg 65. Although still a theory, the amount of progress it has made and the impact throughout the scientific community is remarkable. Especially since String Theory is beginning to look a little fragmented.

General relativity says there is zero time i.e. there is a beginning to the universe where t = 0. Loop Quantum Gravity is making great strides in connecting General Relativity with Quantum Mechanics so that we will be able to use QM to probe into zero-time. Indeed if QLG is a success then there is negative time - time existed before the big bang.

Currently, QLG is being researched at the Max Planck Institute for Gravitational Physics. It suggests that space and time is quantised where these quantised bits of space are related to Graph Theory, but they are given the fancy name of Spin Networks. (and time is called Spin Foam).

In the near future, scientists are hoping to detect discrete space in experiments but at the moment they are trying to link QLG to QM and GR (similiar to testing for the correspondence principle). So far they have calculated (more closely - estimated) that long-wavelength gravitational waves in flat space equate to excitations in the Spin Networks of QLG.

QLG can also successfully model black hole thermodynamics with no problem at all. In fact it reproduces Hawking's radiation - with less work involved!

Tony, you might want to keep track of the advancements made in this new theory. If successful (which they are predicting that experiments will back it up within 50 years) it will explain a lot about how time acts inside black holes and before the big bang.

there is no confirmed proof of the big bag

Doesn't Santa have one of these? Still if we could prove the existance of one we could work out how he carries all those presents.

Sorry for being lame but that really made me laugh! :D

Cheers.

Exactly, there IS no proof that Santa carries a big bag though so Tony is actually right!

Sadly at present there is no confirmed proof of the big bag.
You will never have a proof of anything.
However, there existed cosmological models of the universe that predicted a big bang and predicted Hubble law before it was discovered.
Hubble laws and CBR support these models which have a big bang at the begining.
The assumptions of these models are that the universe is isotropic and homogeneous.

Thank you all for response could you 1100f suggest reading and references, my field is engineering but I find physics/astro facinating, its becomming my Bag Man, 60's stuff, I could not help but find santa bag thing amusing myself. :D

I recommend the book by Hans Ohanian: "Gravitation and Spacetime".It is a good introductory book for general relativity and it has also an introduction to cosmology.
