For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational ...

“Positronium is the simplest atom composed of equal-mass constituents, and until it self-annihilates, it behaves as a neutral ...

A new study achieves unprecedented accuracy in modelling extreme cosmic events like black hole and neutron star collisions by calculating the fifth post-Minkowskian (5PM) order, crucial for ...

Sorta sparked by this comment someone made to me but it's similar to what other people have told me before: I was listening to a lecture on quantum electrodynamics and it helped me conceptualize the ...

Physicists at Stevens Institute of Technology use a 350-year-old theorem that explains the workings of pendulums and planets to reveal new properties of light waves. Credit: Stevens Institute of ...

Researchers have directly observed torsional Alfvén waves twisting through the Sun’s corona — magnetic waves first predicted over 80 years ago. Captured using the Daniel K. Inouye Solar Telescope, ...

The radio waves we see from pulsars have a mysterious glitch – but now we know the ingredients that must be present in the heart of these ultra-dense stellar corpses to give their emissions a hiccup.

Strange pulses that don't seem to abide by the laws of particle physics have been detected in Antarctica. These radio waves, emanating from below the ice, could be evidence of dark matter and have ...
