From the ‘X Files’: “Advanced Civilizations may Live Inside Supermassive Black Holes”
“We hypothesize that the advanced civilizations may live safely inside the supermassive black holes
in the galactic nuclei being invisible from the outside, ” according
to Vyacheslav Dokuchaev –Moscow’s Institute for Nuclear Research of the Russian Academy of Sciences.
Astronomers reported last year that they discovered the most gigantic
black holes ever found in the universe, an abyss 10 times the size of
our solar system, encompassing regions or “event horizons” about five
times the distance from the sun to Pluto or about 2,500 times as massive
as the black hole at the center of the Milky Way.
The biggest of of these monsters, which weighs as much as 21 billion Suns, is in an egg-shaped galaxy known as NGC 4889, the brightest galaxy in the Coma cluster
of thousands of galaxies about 335 million light-years away. The image
at bottom of page shows the central region of the Coma cluster, with
giant elliptical galaxies NGC 4889 and NGC 4874.The
other newly discovered beast, the equivalent of 9.7 billion Suns, is in
the center of NGC 3842, a galaxy that anchors another swirl of stars
known as Abell 1367, 331 million light-years away in Leo.
“These two black holes are significantly more massive than predicted,” the astronomers wrote.
They said their calculations suggest that different evolutionary
processes influence the growth of the largest galaxies and their black
holes than in smaller galaxies. Astronomers have long suspected that
since the universe began it has harboured black holes with a mass the
size of the two newly found giants.
Chung-Pei Ma, led a team of University of California, Berkeley
astronomers who used the Gemini and Keck observatories in Hawaii and the
in Texas and outer space to weigh the black holes in the centers of
galaxies by clocking the speeds of stars orbiting around them; the
faster the stars are going, the more gravity — and thus mass — is needed
to keep the stars from flying away. They report their work in the
journal Nature, which will be published online on Wednesday.
These cosmic gluttons grow in tandem with their galaxies, slurping up gases, planets and stars.
“There is a symbiotic relationship between black holes and their
galaxies that has existed since the dawn of time,” Kevin Schawinski, a
Yale astronomer said in a June study.
Martin Rees, a cosmologist at Cambridge University, called the work
“an incremental step,” noting that the study of these monsters has been a
part of his life for a long time. “It’s good to learn about even bigger
ones,” he said.
One question astronomers would like answered is how these black holes
got so big, billions of times bigger than a typical dead star. Dr. Ma
described it as a kind of nature-versus-nurture argument, explaining
that black holes could grow by merging with other black holes as
galaxies merge to get bigger — “nature” — or by swallowing gas around
them — “nurture.”
“Our discovery of extremely massive black holes in the largest
present-day galaxies suggests that these galaxies could be the ancient
remains of voracious ancestors,” said McConnell. Astronomers think the
supermassive black holes in galaxies could be the missing link between
the quasars of early universe that were powered by giant black holes in
gargantuan feeding frenzies, spewing massive amounts of energy into
The inner workings of these supermassive black holes may be less
hostile than we realize, possibly with stable regions where life and
even planets could exist, according to Russian cosmologist Vyacheslav
Dokuchaev at Moscow’s Institute for Nuclear Research of the Russian
Academy of Sciences. Charged and rotating black holes have a complex
internal structure that allow photons and particles of much greater
magnitude to safely orbit the central singularity.
Gravitational tides within the central singularity are so powerful
that even light gets sucked Dokuchaev has studied the dynamics of
surrounding stable periodic planetary orbits, that neither neither
terminate at the central singularity nor exit the black hole, creating
space for life in the spinning black hearts of the active galactic
Dokuchaev’s research demonstrates that “living inside the eternal
black holes is possible in principle, if these black holes are rotating
or charged and massive enough for weakening the tidal forces and
radiation of gravitational waves to acceptable level.” Type III advanced
civilizations on the Kardashev scale that have achieved mastery of the
resources of their galaxy, could inhabit such black hole interiors.
“The naked central singularity illuminates the orbiting internal
planets and provides the energy supply for life supporting,” he adds.
“Some additional highlighting during the night time comes from eternally
Upon arrival at the event horizon of a black hole a theoretical
observer enters a region where the radial dimension is more time-like
than space-like. Beyond this is the inner Cauchy horizon
where the dimensions again reverse, shifting into a plane where stable
orbits for massive planets exist. The Cauchy horizon is a light-like
boundary where one side of the horizon contains closed space-like
geodesics and the other side contains closed time-like geodesics.
“This internal black hole domain, hidden by the two horizons from the
whole external universe, is indeed a suitable place for safe
inhabitation,” Dokuchaev writes. “The only thing needed is to put your
vehicle or your planet to a stable periodic orbit inside the black
hole.” To exist in this realm, any such civilizations would have to have
overcome extreme conditions, such as massive tidal forces.
“Yet, some difficulties (or advantages?) of a life inside black holes
are worth mentioning, such as a possible causality violation and the
growing energy density in the close vicinity of the Cauchy horizon.”

found at the center of NGC 1277, a flat, compact yellowish galaxy near
the center of this galaxy cluster in the constellation Perseus. (David
