Other models of how these ancient behemoths evolved, including one in which black holes grow by merging with millions of smaller black holes and stars, await further testing.

The other scenario is the «irruption model» in which a high speed black hole storms through a dense gas and the gas is dragged along by the strong gravity of the black hole to form a gas stream.

So thirsty are theorists for new insights into black holes and relativistic processes that, with each LIGO detection, observational astronomers have leapt into action to target those enormous patches of sky, hoping to see some afterglow or other emission of electromagnetic radiation — even though by definition the resulting larger black hole should emit no light.

The best explanation for such an object, which doesn't appear at other wavelengths, is an intermediate - mass black hole (imagined by an artist, above).

Using LIGO's twin giant detectors — one in Livingston, Louisiana, and the other in Hanford, Washington — researchers are said to have measured ripples in space - time produced by a collision between two black holes.

Other so - called hypervelocity stars are thought to have been boosted to their high speeds by close encounters with our galaxy's supermassive black hole (see Hypervelocity stars: Catch them while you can), but this star is too young to have travelled all the way from the centre of the Milky Way.

His second - period stuff on black hole radiation seemed very speculative at first and was disbelieved for quite a while, but then so many other people proved it by different methods that we all agree now that it is correct.

Astronomers have argued for 2 decades about whether there might be other quasars hidden by dust, as are some nearby nonquasar black holes.

Binary black holes are expected to be common in large galaxies, since galaxies are thought to grow by merging with other galaxies, each of which would presumably bring a central black hole with it.

A hypervelocity star appears to be the remains of a three - star system, one star of which was digested by the Milky Way's black hole, with the other two being combined and hurled away.

These seed black holes gain mass and increase in size by picking up the materials around them — a process called accretion — or by merging with other black holes.

On 14 August, the Virgo detector and the two US detectors that make up the Laser Interferometer Gravitational - Wave Observatory (LIGO) all observed the ripples in space - time caused by two black holes smashing into each other and merging.

In other words, according to Morris's theory, a temporarily active black hole would help create stars, and the stars would repay the favor by sending the black hole new dust before explosively burning themselves out.

Last September, that dream came true as 1000 physicists working with the Laser Interferometer Gravitational - Wave Observatory, two huge detectors in Livingston, Louisiana, and Hanford, Washington, sensed a pulse of waves radiated by two massive black holes as they spiraled into each other a billion light - years away.
