Strange Solar Gamma Rays Discovered at Even Higher Energies
There appear to be too many gamma rays coming from the sun. New higher-energy measurements reveal that this excess continues for a bit, then disappears — a cutoff that could help clarify what’s going on.
Asymmetry Detected in the Distribution of Galaxies
Two new studies suggest that certain tetrahedral arrangements of galaxies outnumber their mirror images, potentially reflecting details of the universe’s birth. But confirmation is needed.
Particle Physicists Puzzle Over a New Duality
A hidden link has been found between two seemingly unrelated particle collision outcomes. It’s the latest example of a mysterious web of mathematical connections between disparate theories of physics.
The Spooky Quantum Phenomenon You’ve Never Heard Of
Quantum computers may derive their power from the “magical” way that properties of particles change depending on the context.
Puzzling Quantum Scenario Appears Not to Conserve Energy
By resolving a paradox about light in a box, researchers hope to clarify the concept of energy in quantum theory.
Symmetries Reveal Clues About the Holographic Universe
Physicists have been busy exploring how our universe might emerge like a hologram out of a two-dimensional sheet. New clues have come from the symmetries found on an infinitely distant “celestial sphere.”
Gravitational Waves Should Permanently Distort Space-Time
The “gravitational memory effect” predicts that a passing gravitational wave should forever alter the structure of space-time. Physicists have linked the phenomenon to fundamental cosmic symmetries and a potential solution to the black hole information paradox.
How Quantum Computers Will Correct Their Errors
Quantum bits are fussy and fragile. Useful quantum computers will need to use an error-correction technique like the one that was recently demonstrated on a real machine.
An Ultra-Precise Clock Links the Quantum World With Gravity
Time was found to flow differently between the top and bottom of a single cloud of atoms. Physicists hope that such a system will one day help them combine quantum mechanics and Einstein’s theory of gravity.
