An underwater observatory recently detected a startlingly energetic cosmic neutrino. One possible cause involves a phenomenon ...

One of the greatest mysteries of modern physics, the "black hole information paradox," might have finally found an elegant ...

Some things in cosmology may simply be unknowable. Why is there something rather than nothing? What lies outside the universe? What is inside a black hole? That last one has been niggling at ...

In 1916, only a year after Albert Einstein had published his general theory of relativity, Karl Schwarzschild used mathematical calculations to show this: If sufficient mass could be placed into an ...

Add Yahoo as a preferred source to see more of our stories on Google. A new study published this week has confirmed a prediction about black holes that Stephen Hawking made more than 50 years ago.

An unusually massive black hole in the very early universe may be a kind of exotic, star-less black hole first theorised by Stephen Hawking. In August, Boyuan Liu at the University of Cambridge and ...

Centuries before anyone pointed a telescope at the sky, Isaac Newton figured out how gravity works. He showed that any object with mass pulls on every other object—a result that explained falling ...

Seventeen miles of underground tunnel, thousands of superconducting magnets, and protons whipped to a fraction below light speed have given the Large Hadron Collider a reputation that borders on myth.

An artist's concept of a tidal disruption event (TDE), which happens when a star passes close to a supermassive black hole. The gravity of the black hole pulls material from the star and launches a ...

A new mathematical model of a wormhole suggests that two black holes can be “cut and pasted.” Cut and paste is an official concept in math, referring to two surfaces that may be transposable. In this ...

Scientists have spotted the brightest flare yet from a supermassive black hole that shines with the light of 10 trillion suns. These bursts of light and energy can come from things like tangled-up ...
