Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that has long posed a problem: According to physicists’ best current ...

The theorized unseen structure of spacetime could also explain of the outstanding questions about the accelerating expansion ...

The particle in question, known as a sterile neutrino, was supposed to only interact with gravity and have zero interactions ...

Using the Super Proton Synchrotron, the team created beams of electron-positron pairs and passed them through a meter-long region of plasma. This setup served as a scaled laboratory version of a ...

Experimental particle physicists working at the MicroBooNE experiment at Fermilab National Accelerator Laboratory have found ...

The universe's matter-antimatter asymmetry, where matter significantly outweighs antimatter despite their theoretically equal creation at the Big Bang, remains a major unsolved problem in physics.

After years of careful investigation, researchers working on the Micro Booster Neutrino Experiment (MicroBooNE) have determined that a ...
