A black hole made from pure light is impossible, thanks to quantum physics
A “kugelblitz” is a black hole made of concentrated electromagnetic energy. But it’s not possible to make one, according to new calculations.

Physicists measured Earth’s rotation using quantum entanglement
The experiment is a step toward testing how quantum physics interfaces with gravity.

The second law of thermodynamics underlies nearly everything. But is it inviolable?
Two centuries on, scientists are still seeking a proof of the Second Law and why heat always flows from hot to cold.

Scientists propose a hunt for never-before-seen ‘tauonium’ atoms
Made of heavy relatives of the electron, the exotic atoms could be used to test the theory of quantum electrodynamics.

Here’s how ice may get so slippery
Ice’s weirdly slick exterior might originate from the boundaries between two different types of ice that form on the surface of frozen water.

The neutrino’s quantum fuzziness is beginning to come into focus
An experiment studying the neutrino’s “wave packet” sets a limit on the uncertainty of the subatomic particle’s position.

The universe may have a complex geometry — like a doughnut
Physicists haven’t yet ruled out the possibility that the universe has a complicated topology in which space loops back around on itself.

Scientists developed a sheet of gold that’s just one atom thick
Ultrathin goldene sheets could reduce the amount of gold needed for electronics and certain chemical reactions.
