Black holes are usually cast as cosmic dead ends, places where matter and information vanish without a trace. A new mathematical model instead treats them as potential junctions, suggesting that under ...

Now, decades later, a new species of traversable wormhole has emerged, free of exotic material and full of potential for helping physicists resolve a baffling paradox about black holes. This paradox ...

Add Yahoo as a preferred source to see more of our stories on Google. In 2019, LIGO and Virgo detected GW190521—a mysterious gravitational wave that could mark either the colossal merger of two black ...

In some ways, a wormhole might look like a black hole. And the wormhole would look like a sphere, not a hole. Einstein's theory of general relativity allows for the possibility of wormholes, but there ...

For obvious reasons, we do not know what the inside of a black hole looks like. But thanks to theoretical physics, we can ask what the inside should look like if Einstein's theory of gravity and the ...

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 ...

Science fiction is full of amazing space phenomena. Some of those phenomena have gone from theory to reality — like black holes and pulsars. But what about wormholes? These portals through space are ...

In May 2019, astronomers picked up something strange in the fabric of spacetime. The LIGO and Virgo detectors recorded a gravitational wave that lasted just one-tenth of a second. The signal, known as ...
