Gravity's Engines
by Caleb Scharf
In the late 18th century,
black holes were simply an audacious thought experiment; today we know that the universe is strewn with billions, perhaps even trillions, of these time - bending objects.
Linking high - energy cosmic particles

This idea, proposed
by Juan Maldacena at the Institute for Advanced Study
in Princeton, N.J., is called the holographic principle: Just as a two - dimensional hologram can depict a three - dimensional object, the surface of a
black hole theoretically reveals everything inside of it.
The process of
black hole formation was first described
by J. Robert Oppenheimer and Hartland Snyder
in the same issue of the Physical Review as Bohr and Wheeler's fission paper.
Computer simulations suggest that when two
black holes spiral towards each other on a collision course, much of the gas and dust
in the spinning accretion disc surrounding each of them is ripped away
by the gravity of the other.
«With ALMA we can see that there's a direct link between these radio bubbles inflated

in spacetime generated
by colliding
black holes and neutron stars and detected for the first time
in 2015
by the Laser Interferometer Gravitational - Wave Observatory (LIGO).

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 our own galaxy we have been able to electromagnetically observe
black holes orbited
by stars and map their behaviour — notably their rapid spinning.
By contrast to
black holes, these stars can not gain
in mass arbitrarily; past a certain limit there is no physical force
in nature that can counter their enormous gravitational force.
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

For the first time, scientists worldwide and at Penn State University have detected both gravitational waves and light shooting toward our planet from one massively powerful event
in space — the birth of a new
black hole created
by the merger of two neutron stars.
Using similar techniques originally inspired
by string theory, Strominger's group has computed the spectrum of gravitational waves emitted when compact objects like stars fall into giant
black holes — predictions that could be verified
by the future Evolved Laser Interferometer Space Antenna, planned to launch
in two decades (or maybe sooner).
