White holes are the hypothetical opposite of black holes. While black holes suck in everything, including light, white holes are theorized to do the exact opposite—nothing can enter, and they ...

Black holes, with their cosmic vacuum cleaner meme in hand, have captured the imagination of scientists and the general public in approximately equal numbers for centuries. But imagine those dark ...

A new study suggests that a black hole singularity—where time and matter are condensed into infinitely small space—could be a transition to a beginning. This beginning is a white hole—a theoretical ...

Albert Einstein’s theory of gravity, general relativity, is famously incomplete. As proven by physics Nobel laureate Roger Penrose, when matter collapses under its own gravitational pull, the result ...

The black hole, with an official name of 1ES 1927+654, is located in the distant constellation Draco. Astronomers have been monitoring the black hole for years, primarily since 2018 when the mass was ...

Theoretical physicists have long debated the possible existence of wormholes, which are mathematically possible, but no evidence points to their physical existence. One theory suggests that these ...

"This tells us that objects like white dwarfs may be able to live very close to an event horizon for a relatively extended period of time." When you purchase through links on our site, we may earn an ...

What can astronomers learn from observing black holes that suddenly wake up? This is what a recent study published in Nature Astronomy hopes to address as an international team of researchers ...

WASHINGTON, Jan 14 (Reuters) - Scientists have detected emanating from the nucleus of a galaxy relatively close to our Milky Way flashes of X-rays gradually increasing in frequency that seem to be ...

Black holes are often considered terrors of the known universe. Supermassive black holes are regions of space where the pull of gravity is so intense that even light doesn't have enough energy to ...
