Life in a black hole might survive?

The research is based on photon singularity, well within the event horizon orbits around a black hole. If a hypothetical planet is torn by immense tidal forces to shreds avoids can it spiral orbit have a complex. The idea is far fetched, and may be incorrect, but philosophical questions raised.

Planets and perhaps even advanced life could exist in theory, in a black hole according to a new theory.

The idea of the physicist Professor Vyacheslav Dokuchaev of the Russian Academy which huge gravity devoured Sciences, Moscow, Wells against the common belief that black holes are all going too close calls is displayed.

In a paper written for the magazine journal of cosmology and astroparticle physics and his appearance on the pre-press Web site arXiv.org, Dokuchaev follows previous theories that subatomic particles, as can some stable orbits within the internal structure of photons black holes have.

He says supermassive in the center of galaxies, black holes could allow particles, and orbit without even planets with life, the singularity is destroyed.

The singularity is located in the heart of a black hole, and is the place where the laws of physics and space time break.

It is a region beyond which objects need to travel faster than the speed of light to escape the black hole, surrounded by the event horizon. Because nothing theoretically faster than the speed of light can travel, nothing escapes once it has passed the event horizon.

In his presentation, Dokuchaev studied hypothetical orbits in the area between the event horizon and the singularity to understand, their dynamics.

He says, while conventional orbits would not be possible, there are some places where particles and planets could have stable but unusual spiral lanes.

Dokuchaev calculated, would be such a planet lit by the singularity and photons captured in the same orbit of hell.

"This planet even supports may be a complex chemistry rich enough so that life to develop", says Dokuchaev.

"Advanced civilizations can safely into the black hole life without visible from the outside".

Dokuchaev is that such a civilization to cope with exceptional circumstances, including large tidal forces and massive energy densities such as photons would have to be caught.

And he there is also the problem of violations of causality, where not the rules of space and time.

Astronomer Dr David Floyd from the Australian Observatory and the University of Melbourne says even if the theory is correct, it would be impossible to know, what happens beyond the event horizon of a black hole.

"At this point - and perhaps forever - we limited, untestable claims that," says Floyd.

"As far as we know matter in free fall, so that would be it all in this tiny infinitesimal point center would fall in the singularity is."

Floyd says, that the paper, which is a disadvantage of the paper, that it is radiation has no effect on orbits in the black hole.

"It would not much draw to produce, which is described in Dokuchaev, so that she collapse would slow down on the singularity take paper the orbits".

But Floyd admits that it opens up some interesting philosophical questions.

"Given the number of black holes in the universe - land - one could conclude that life is inevitable in at least one of them, if it really stable orbits," he says. "Perhaps there are entire universes in black holes."
