This Physicist Discovered an Escape From Hawking’s Black Hole Paradox
The five-decade-old paradox — long thought key to linking quantum theory with Einstein’s theory of gravity — is falling to a new generation of thinkers. Netta Engelhardt is leading the way.
Eternal Change for No Energy: A Time Crystal Finally Made Real
Like a perpetual motion machine, a time crystal forever cycles between states without consuming energy. Physicists claim to have built this new phase of matter inside a quantum computer.
How Many Numbers Exist? Infinity Proof Moves Math Closer to an Answer.
For 50 years, mathematicians have believed that the total number of real numbers is unknowable. A new proof suggests otherwise.
Physicists Identify the Engine Powering Black Hole Energy Beams
Supermassive black holes emit jets of white-hot plasma that stretch thousands of light-years across the cosmos. For the first time, researchers have identified what’s creating these jets.
Cosmic Map of Ultrahigh-Energy Particles Points to Long-Hidden Treasures
Ultrahigh-energy cosmic rays twist and turn on their way to Earth, which has made it nearly impossible to identify the colossal monsters that create them.
‘Last Hope’ Experiment Finds Evidence for Unknown Particles
Today’s long-anticipated announcement by Fermilab’s Muon g-2 team appears to solidify a tantalizing conflict between nature and theory. But a separate calculation, published at the same time, has clouded the picture.
Quantum Mischief Rewrites the Laws of Cause and Effect
Spurred on by quantum experiments that scramble the ordering of causes and their effects, some physicists are figuring out how to abandon causality altogether.
Decades-Long Quest Reveals Details of the Proton’s Inner Antimatter
Twenty years ago, physicists set out to investigate a mysterious asymmetry in the proton’s interior. Their results, published today, show how antimatter helps stabilize every atom’s core.
What Dust From Space Tells Us About Ourselves
Micrometeorites constantly fall on every corner of Earth. Matthew Genge is using these shards of interplanetary space to understand Earth and its place in the solar system.
