Scientists have created an optical device capable of mimicking black holes and the still hypothetical white holes. This ...

By breaking a decades-old paradigm and rethinking the role that the dimension of time plays in physics, researchers from the ...

In the realm of general relativity, black holes are well-known for their ability to trap light and matter by bending ...

A team of scientists has developed a recipe for black holes that eliminates one of the most troubling aspects of physics ... the very fabric of space-time (the three dimensions of space united ...

Nonlocal correlations that define quantum entanglement could be reconciled with Einstein’s theory of relativity if space–time had two temporal dimensions. That is the implication of new theoretical ...

Boston Globe via Getty Images In her new book, Knocking on Heaven's Door, Harvard University theorist Lisa Randall explores how physics ... time symmetry and whether there are extra dimensions.

Instead of collapsing forever, black holes might "flip" into white holes, spewing matter and time, as shown in a University ... offering a way to unite two of physics' greatest but clashing ...

Astronomers have used the James Webb Space Telescope (JWST) to revisit a misunderstood black hole thought to be gulping ...

While black holes consume everything, their mirror image—white holes—would do the opposite ... This theory could explain where time, matter, and energy go after collapse.

General relativity says that matter warps space and time; black holes are simply very dense agglomerations of matter. But simple it isn’t. General relativity’s equations fail catastrophically ...

Black holes — regions of space-time with extreme curvature — first arose as a concept from solutions to Einstein's field equations suggested by German physicist and astronomer Karl ...
