As proven by physics Nobel laureate Roger Penrose, when matter collapses under its own gravitational pull, the result is a ...

The event horizon, the point of no return, is the boundary where the singularity's gravitational pull becomes inescapable.

Backreaction refers to the effect that matter and energy have on the curvature of spacetime (the fabric of the universe), as ...

Through gentle exposure to concepts such as spacetime curvature and general relativity, you will discover some of the most curious consequences of gravitational physics, such as black holes, neutron ...

The only quantities a black hole has are gravitational invariants, which are observables at infinity and the scalar curvature R. Functions of gravitational invariants are also gravitational ...

Avi Loeb explores how experimental quantum gravity may one day help to connect the dots between quantum mechanics and general ...

This is the gargantuan black hole that lives at the centre of our galaxy, pictured for the very first time. Known as Sagittarius A*, the object is a staggering four million times the mass of our Sun.

This curvature thus controls the motion of inertial objects. Modern research in gravitational physics includes studying applications of numerical relativity, black hole dynamics, sources of ...
