Black holes

The idea that time can be warped was proposed by Albert Einstein in his pioneering theories of special relativity and general relativity.

The idea of wormholes was predicted by Einstein’s theory of general relativity in 1916.

Scientists think that at the heart of nearly every galaxy lies a supermassive black hole (SMBH) with immense gravity.

Researchers say they have detected remnants of a universe that existed before our own.

This is the first time astronomers have directly imaged the brutal phenomenon.

The broadcast will "create a link" between Hawking's presence on Earth, his desire to visit space and his scientific explorations of the universe, his daughter said.

Last year's collision was the first in which scientists could actually see what was happening during and after the collision.

The behemoth gobbles up the equivalent of our sun's mass every two days.

Ancient black holes, dwarf galaxies and invisible halos might unlock the secrets of dark matter.

Competing winds from black holes and stars wrestle to give this galaxy its strange butterfly shape.

It might surprise you.

The black holes surround the supermassive black hole at the center of the Milky Way.

The fundamental laws of physics guarantee that every process that happens “forward in time” can also happen “backwards in time.”

Black holes are voracious eaters, but they don't have the nicest table manners.

Marika Taylor, a professor of Theoretical Physics at the University of Southampton, reminisces about her time spent studying under the late Stephen Hawking.

Millions have had their cosmic horizons widened by his best-selling books; and even more, around the world, have been inspired by a unique example of achievement against all the odds.

It's not just about the detectors picking up a signal—scientists also have to realize it's there soon enough to enlist colleagues in the investigation.

A fundamental equation has cracked the evolution of how planets swarm around the sun.

Light from the jets can outshine entire galaxies.

The planets face supernovas, gamma-ray bursts and gravity-disrupting stars in the crowded center of the Milky Way.

Neutrinos and gamma rays may be the "daughter particles" of ultra-high-energy cosmic rays.

The discovery marks the first inactive black hole ever found at the heart of a giant globular star cluster.

The gassy giant has big implications for physics.

Unfortunately for black holes, we can still take pictures.

These mammoth cosmic engines have transformed our universe.

"Growing black holes behave like babies that become too energetic and throw their food off the table once they eat enough."

“Now that we’re in the business of finding things, we can say, well, soon we’ll know.”

“This is remarkable that the supermassive black hole is able to impact stars forming at such large distances.”

Mathematicians have discovered the answer.

Study suggests our current models of black holes are "oversimplified."
