The James Webb Space Telescope (JWST), launched in 2022, continues to reshape how we view the cosmos. Designed to look deeper into space and further back in time than any previous instrument, it has ...

Particles orbiting a black hole could collide at colossal energies, generating collision products that may offer valuable ...

Black holes are places where gravity is so powerful that nothing — not even light — can escape. Rather than being empty, black holes are chock full of matter that gets squeezed into a teensy space.

The German physicist Karl Schwarzschild predicted the existence of black holes for the first time in 1915. He used Einstein’s equations describing general relativity—published only months ...

A new discovery using the James Webb Telescope has implied we may live in a black hole. The telescope, launched by NASA three years ago, gives us the ability to take photographs of deep space with ...

A black hole's event horizon, also called the Schwarzschild radius, is the radius within which its gravity supersedes all other forces of nature. Inside a black hole's event horizon, gravity is so ...

Instead of viewing entropy in terms of the enclosing sphere, we arrive at a toroidal representation, where the inner radius is the Schwarzschild radius, and the outer radius remains the smallest ...

As we have pointed out, according to Schwarzschild’s solution, every object in the universe has a Schwarzschild radius and could therefore become a black hole, at least in principle.

Born in a black hole? Black hole cosmology, also known as "Schwarzschild cosmology," suggests that our observable universe might be the interior of a black hole itself within a larger parent universe.

Because the shadow is caused by the gravitational bending and capture of light at the event horizon, its size and shape can be used to infer the black hole’s mass. The larger the shadow, the higher ...
