Event horizon

In general relativity, an event horizon is a region in spacetime beyond which events cannot affect an outside observer.

Frame-dragging

Frame-dragging is an effect on spacetime, predicted by Einstein's general theory of relativity, that is due to non-static stationary distributions of mass–energy.

Gamma-ray burst

In gamma-ray astronomy, gamma-ray bursts (GRBs) are extremely energetic explosions that have been observed in distant galaxies.

John Archibald Wheeler

John Archibald Wheeler (July 9, 1911 – April 13, 2008) was an American theoretical physicist.

Lense–Thirring precession

In general relativity, Lense–Thirring precession or the Lense–Thirring effect (named after Josef Lense and Hans Thirring) is a relativistic correction to the precession of a gyroscope near a large rotating mass such as the Earth.

Negative mass

In theoretical physics, negative mass is matter whose mass is of opposite sign to the mass of normal matter, e.g. −1 kg.

Oxford University Press

Oxford University Press (OUP) is the largest university press in the world, and the second oldest after Cambridge University Press.

Penrose process

The Penrose process (also called Penrose mechanism) is a process theorised by Roger Penrose wherein energy can be extracted from a rotating black hole.

Quasar

A quasar (also known as a QSO or quasi-stellar object) is an extremely luminous active galactic nucleus (AGN).

Remo Ruffini

Remo Ruffini (born May 17, 1942, La Brigue, Alpes-Maritimes, at that time, Briga Marittima, Italy).

Roger Penrose

Sir Roger Penrose (born 8 August 1931) is an English mathematical physicist, mathematician and philosopher of science.

Rotating black hole

A rotating black hole is a black hole that possesses angular momentum.

Schwarzschild radius

The Schwarzschild radius (sometimes historically referred to as the gravitational radius) is a physical parameter that shows up in the Schwarzschild solution to Einstein's field equations, corresponding to the radius defining the event horizon of a Schwarzschild black hole.
