A new particle detector has passed a crucial test that shows it is ready to detect the "ashes" left over from a unique primordial soup that filled the universe immediately after the Big Bang. The ...

Forget about turtles; for all practical purposes, it’s really particles all the way down. Consider the seemingly simple matter of their size, the very thing that makes them so alien. We’re typically ...

At the foot of the thickly forested Dashi Hill, in southern China’s Guangdong province, pre-approved visitors can take a ride aboard a unique yellow train. Rather than winding through the serene ...

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 ...

Two recent studies by Professor Stefano Profumo at the University of California, Santa Cruz, propose theories that attempt to answer one of the most fundamental open questions in modern physics: What ...

An artistic illustration of the mechanism proposed by Professor Stefano Profumo where quantum effects near the rapidly expanding cosmic horizon after the Big Bang gravitationally generate dark matter ...

It may sound like a plot twist out of a science fiction novel, but researchers have detected mysterious radio signals coming from beneath the Antarctic ice that appear to be inconsistent with the ...

It is just over a year since Cern, home to the Large Hadron Collider (LHC), became the base for the three-year pilot phase of the Open Quantum Institute (OQI). The OQI is a multi-stakeholder, global, ...

When trying to answer questions as deep as “what makes up the universe,” advance planning is key. On June 11, the National Academies of Science, Engineering and Medicine announced the result of a ...

Next week, physicists will meet in Venice to discuss the future of European particle physics research. Early in his career, Karl Jakobs worked on physics experiments that had a few hundred ...

Mysterious radio signals detected emanating from Antarctica's ice have left particle physicists baffled. The pulses were detected by the Antarctic Impulsive Transient Antenna (ANITA)—an array of radio ...

A cosmic particle detector in Antarctica has detected a series of bizarre signals that defy the current understanding of particle physics, according to an international research group that includes ...
