Theorists apply loop quantum gravity theory to black hole May 31, by Bob Yirka, Phys. The black hole is shooting out jets of radio waves. In so doing, as they describe in their paper published in the journal Physical Review Letters, they suggest that instead of a singularity existing at its center, there is a portal to another universe.
Theory also suggests that a similar singularity should exist at the center of black holes, but again, general relativity fails to describe them properly. Worse, there is the problem of the information loss paradox—if something falls into a black hole and is eventually squeezed to a singularity, what happens to the information it contained?
To address these problems, Abhay Ashtekar and his team at Pennsylvania State University, back incame up with a theory known as loop quantum gravity.
They suggested that instead of a singularity existing just before the Big Bang, there was the remains of a crunched down universe that had existed prior to the one that exists now. Since that time, some in the field have begun to refer to the theory as the Big Bounce, to replace the name Big Bang.
Because their model worked so well, the two suggest that it would likely work with real black holes as well.
If this new theory is correct, they note, it would do away with the information loss paradox and open the door to the possibility of black holes being portals to other universes.
Through a rescaling, we make the algebra of Hamiltonian constraints Abelian, and therefore the constraint algebra is a true Lie algebra. This allows the completion of the Dirac quantization procedure using loop quantum gravity techniques. We can construct explicitly the exact solutions of the physical Hilbert space annihilated by all constraints.
New observables living in the bulk appear at the quantum level analogous to spin in quantum mechanics that are not present at the classical level and are associated with the discrete nature of the spin network states of loop quantum gravity.
The resulting quantum space-times resolve the singularity present in the classical theory inside black holes.Child development theories focus on explaining how children change and grow over the course of childhood.
Such theories center on various aspects of development including . I like this line of thinking. As mater and space gets closer to a black hole in our universe the time slow to an infinitely slow speed ( a virtually a time stop to us at the event horizon).

Individual contributors to classical liberalism and political liberalism are associated with philosophers of the kaja-net.comlism as a specifically named ideology begins in the late 18th century as a movement towards self-government and away from kaja-net.com included the ideas of self-determination, the primacy of the individual and the nation, as opposed to the state and religion.
The classical theory of concepts is one of the five primary theories of concepts, the other four being prototype or exemplar theories, atomistic theories, theory-theories, and neoclassical theories.
The classical theory implies that every complex concept has a classical analysis, where a classical.
