If all goes well, as early as next year a virtual telescope with the sensitivity of an Earth - sized radio dish will deliver images of a bright ring of hot gas surrounding a circular shadow: the heart of a black hole, bounded by the event horizon.

The Nottingham experiment was based on the theory that an area immediately outside the event horizon of a rotating black hole — a black hole's gravitational point of no return — will be dragged round by the rotation and any wave that enters this region, but does not stray past the event horizon, should be deflected and come out with more energy than it carried on the way in — an effect known as superradiance.

At the heart of a blazar lies a supersized black hole with millions of times the sun's mass surrounded by a disk of hot gas and dust.

A computer simulation of two black holes merging into one created recently by scientists at the University of Texas and the Theoretical Astrophysics Centre in Copenhagen should provide them with a detailed idea of what type of gravity waves to expect.

Likewise, if black holes act like information mirrors, as Hayden and Preskill suggested, a particle falling into a black hole would be followed by an antiparticle coming out — a partner with the opposite electric charge — which would carry the information contained in the spin of the original particle.

One possible solution, proposed in 2007 by physicists Patrick Hayden of Stanford University and John Preskill of Caltech, is that the black hole could act like a mirror, with information about infalling particles being reflected outward, imprinted in the Hawking radiation.

«By combining the detection of gravitational waves with simulations we could ultimately work out when and how the first seeds of supermassive black holes formed.»

And the reason you can get energy out of a black hole, that swallower of all things, is that the energy you detect never really got into the black hole to begin with — it's associated with the space - time whirlpool created outside the event horizon by the black hole's rotation.

In recent years, scientists have confirmed a remarkable link between two kinds of objects that should, by all rights, have nothing to do with each other: black holes and strange metals.

For many aspects of the simulation, researchers can start their calculations at a fundamental, or ab initio, level with no need for preconceived input data, but processes that are less understood — such as star formation and the growth of supermassive black holes — need to be informed by observation and by making assumptions that can simplify the deluge of calculations.
