Journey To The Limits Of Spacetime. Hypothetically. With A Computer

Posted February 24, 2013 4:41 PM

From Science 2.0:

Last month, physicists predicted the formation of accretion disks and relativistic jets that warp and bend more than previously thought, shaped both by the extreme gravity of black holes and by powerful magnetic forces generated by their spin.

Black holes, absences at the center of both galaxies and science fiction, shape the growth and death of stars around them through both their powerful gravitational pull and explosive ejections of energy - a pull so strong close to a black hole that even light cannot escape from within, hence the difficulty in observing them directly.

"Over its lifetime, a black hole can release more energy than all the stars in a galaxy combined," said co-author Roger Blandford, director of the Kavli Institute for Particle Astrophysics and Cosmology and a member of the U.S. National Academy of Science. "Black holes have a major impact on the formation of galaxies and the environmental growth and evolution of those galaxies."

"Over its lifetime, a black hole can release more energy than all the stars in a galaxy combined," said co-author Roger Blandford, director of the Kavli Institute for Particle Astrophysics and Cosmology and a member of the U.S. National Academy of Science. "Black holes have a major impact on the formation of galaxies and the environmental growth and evolution of those galaxies."

It would seem that more information is coming to light as to the Black Holes function in the universe.

I commented on this in my post 5 "The Big Bounce Instead of the Big Bang?"

I can not conceive that Black holes can absorb so much energy and hold it for ever without without some major event in its lifetime, which is very much greater than our very small time span, conceivably we will never see one of these reactions. Probably just as well!
