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 ...

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 ...

Here’s what you’ll learn when you read this story: In May of 2019, a short-duration binary black hole (BBH) merger contained no evidence of the inspiral signal typical of these kinds of a ...

Back in 2019, the gravitational wave observatories LIGO and Virgo detected major ripples in spacetime. While astronomers generally agree that the event, dubbed GW190521, was the result of two black ...

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 ...

John Preskill, a black hole and quantum gravity expert at Caltech, says the new traversable wormhole comes as a surprise, with implications for the black hole information paradox and black hole ...

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 ...

Back in the prehistoric days of theoretical astrophysics (1985), in a mystical and exotic corner of planet Earth (Fresno, California), a man sat in the back of a car and tried to break the spacetime ...

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 ...

The universe seems to be spinning, and that could explain what dark energy is and why it's weakening while revealing our place within the multiverse.

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 ...
