Early Universe was packed with mini black holes
A research group at Cambridge think that the universe might once have been packed full of tiny black holes. Dr Martin Haehnelt, a researcher in the group led by Astronomer Royal Martin Rees, will present new evidence to support this controversial idea at the Institute of Physics conference Physics 2005 in Warwick. Most cosmologists believe that supermassive black holes grew up in big galaxies, accumulating mass as time went on. But Haehnelt says there is increasing evidence for a different view – that small black holes grew independently and merged to produce the giants which exist today.
Haehnelt points to evidence from recent studies of the cosmic microwave background (CMB). This radiation, sometimes called "the echo of the big bang" has been travelling unaltered through space since the universe was just 400,000 years old. At that moment the universe cooled through a critical point, letting CMB radiation travel freely for the first time – as though a cosmic fog had lifted. But new evidence shows that 10 to 15 percent of this radiation has been scattered since then. This indicates a re-warming of the universe which nobody had expected. Haehnelt explains that this could indicate an era in which small black holes were commonplace. "Matter accreting around a black hole heats up," he explains, "and this heating could be a sign that small black holes were widespread in the Universe at that time." If small black holes merged to form the supermassive variety found at the centres of galaxies, there could be telltale evidence. Such a merger begins with two black holes going into orbit around each other, spiralling ever closer together. In the cataclysmic blast of energy when they finally merge, any asymmetry can send the resulting black hole flying off into space. "If this happened," says Haehnelt, "we might find the occasional galaxy with its central supermassive black hole missing." The evidence is by no means conclusive. Until it is, the CMB results will remain a source of heated debate. Dr Martin Haehnelt is a Reader in Cosmology and Astrophysics at the Institute of Astronomy in the University of Cambridge.

The very early universe resembled beer foam more than a giant soap bubble?

[Ernest_at_the_Beach]

New theory here....new to me anyway.

[PatrickHenry]

Thanks. Not much of an article, but it's worth a ping.

An elite subset of the Evolution list. See the list's description at my freeper homepage. Then FReepmail to be added or dropped.

[Mike Darancette]

This indicates a re-warming of the universe which nobody had expected.

Universal Warming?? Save the Universe, Carpool.

[Ernest_at_the_Beach]

The Global Warming thru computer models will need to expand their models, need new grants for much bigger computers....they will be happy with this ....

Early Universe was packed with mini black holes ~~

but, did it really satisfy?

[AntiGuv]

Well, this would certainly raise the intriguing question of where did all the mini-holes come from; then again, we don't know where the supermassive black holes originated in any case.

[Dutch Boy]

An even a bigger question.... Where can I get a high paying job that requires coming up with theories that are impossible to prove?

[oh8eleven]

Most cosmologists believe that supermassive black holes grew up in big galaxies...
Wow, I didn't know they were that smart.

[AntiGuv]

This hypothesis (rather than theory) is not "impossible" to prove; it is difficult to prove.

ROFL!!!!
