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.

The MIT - led team looked through data collected by two different telescopes and identified a curious pattern in the energy emitted by the flare: As the obliterated star's dust fell into the black hole, the researchers observed small fluctuations in the optical and ultraviolet (UV) bands of the electromagnetic spectrum.

In the failed supernova of a red supergiant, the envelope of the star is ejected and expands, producing a cold, red transient source surrounding the newly formed black hole, as illustrated by the expanding shell (left to right).

The importance of V404 Cygni can best be understood by looking back some 20 years to the effort that went into finding the first convincing candidate for a black hole which, by coincidence, lies in the same part of the sky and is known as Cygnus X-1.

There, young stars, born during the merger, will explode as supernovas, and a quasar — a giant black hole ignited by the galactic collision — might spew energetic radiation.

Although sufficient to disintegrate the primordial star, almost all of the heavy elements such as iron, were consumed by a black hole that formed at the heart of the explosion,» he says.

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.

Until then, scientists regarded black holes as simple objects — quite literally holes in space, completely described by just three variables: their mass, spin and charge.

Another giveaway is that light from stars that lie behind a black hole as seen from Earth should be deflected by its gravity.

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.
