(via Sabine Hossenfelder) White holes are theoretical bodies in physics that are basically time-reversed black holes, meaning instead of permanently trapping matter inside themselves, they release it ...

Black holes seem to get all the attention. But what about their mirror twins, white holes? Do they exist? And, if so, where are they? To understand the nature of white holes, first we have to examine ...

A groundbreaking new study proposes that black holes, which absorb everything into an inescapable void, may eventually ...

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 ...

Do black holes die? And if so, what happens when they're gone? A new theory suggests that these galactic vacuums hit a point at which they can collapse no further. At this moment, a black hole ceases ...

Do black holes, like dying old soldiers, simply fade away? Do they pop like hyperdimensional balloons? Maybe they do, or maybe they pass through a cosmic rubicon, effectively reversing their natures ...
