For the first time, researchers have seen how light behaves during a mysterious phenomenon called 'imaginary time'. When you shine light through almost any transparent material, the gridlock of ...

One of physicist Stephen Hawking's most famous paradoxes may finally be solved: Black holes may in fact hang onto information about the massive stars that created them, new research indicates. This ...

Imaginary time is a wonky concept for our time-bound brains, but in quantum theory and mathematics, it’s a useful tool for exploring radiation's interaction with materials. A new study from scientists ...

Hawking radiation suggests that black holes are not completely black but emit faint radiation and decay over time. The idea involves virtual particles that spontaneously appear and disappear due to ...

Primordial black holes may be exploding throughout the universe. If we can catch them in the act, it could pave the way to new physics, a study suggests. When you purchase through links on our site, ...

Researchers have found that the universe around us is decaying far more quickly than we thought, thanks to Hawking radiation, the idea that black holes “evaporate” over time due to the quirks of ...

Scientists have found that the universe’s decay rate is much faster than previously thought. A team of three scientists from Radboud University, Netherlands, calculated how long it would take for ...

Analogue models of black holes offer an innovative experimental framework to probe phenomena that otherwise lie at the frontiers of astrophysics. By utilising systems such as superfluid helium, atomic ...

We’ve searched the skies for alien signals in the form of radio waves and reflected light from massive orbiting structures. But physicists Gia Dvali (of the Max Planck Institute for Physics) and Zara ...

On its own, a black hole is remarkably easy to describe. The only observable properties a black hole has are its mass, its electric charge (usually zero), and its rotation, or spin. It doesn’t matter ...
