In the depths of the Mediterranean Sea, at precisely 2,450 meters below surface, an extraordinary cosmic discovery has revolutionized our understanding of high-energy astrophysics. The KM3NeT telescope network detected what scientists now consider the most energetic cosmic neutrino ever recorded, carrying an unprecedented 120 petaelectronvolts of energy. This remarkable detection occurred in February 2023, during the telescope’s construction phase when only 10% …

A tiny particle that smashed into Earth with a record-shattering energy of 220 petaelectronvolts could be the last scream of an evaporating black hole. According to a new theoretical paper, the 2023 neutrino event named KM3-230213A can be explained by a burst of Hawking radiation emitted as a primordial black hole puffed into nothing. Moreover, physicists Alexandra Klipfel and David …

“Hearst Magazines and Yahoo may earn commission or revenue on some items through these links.” Here’s what you’ll learn when you read this story: In 1956, physicist David Pines theorized the existence of a massless, neutral plasmon called a “demon” that could help explain the superconductivity of some exotic materials. Now, scientists at the University of Illinois Urbana-Champlain have found …

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 sPHENIX detector is the latest experiment at the Relativistic Heavy Ion Collider (RHIC) ring accelerator located at Brookhaven National Laboratory in Upton, New York. The …

An estimated one in five Americans harbors a leading risk factor for heart disease and heart attacks, often without even knowing it.  Lipoprotein(a) is a type of LDL particle, the primary transporter of cholesterol to the body’s tissues, that can seep into the walls of the arteries. LDL is commonly known as the ‘bad’ cholesterol.  Lp(a) is a dangerous form …

The verdict is in. The detection of a cosmic neutrino that smashed into Earth with an unprecedented energy level is not a glitch or an error, but a real detection of a real particle. In February 2023, a detector called KM3NeT, located deep under the Mediterranean Sea, picked up a signal that seemed to indicate a neutrino with a record-shattering …

Sign up for the Starts With a Bang newsletter Travel the universe with Dr. Ethan Siegel as he answers the biggest questions of all. CERN’s Large Hadron Collider (LHC) is history’s most powerful particle physics machine. Deep underground, this tunnel is part of interior workings of the Large Hadron Collider (LHC), where protons pass each other at 299,792,455 m/s while …

There’s nothing particle physicists like more than crashing particles together and seeing what comes out of the mess. Such experiments can help us find evidence of particles and processes predicted by the Standard Model of particle physics – such as the Higgs Boson – or allow us to probe the conditions of the early universe, for example. Particle accelerators, though, …

Researchers at the University of Southern California (USC) in the US turned to an often overlooked particle for storing and processing quantum information to overcome the fragility of quantum computers and make them more universal in the near future. Positioning one such particle in a quantum computer can help overcome errors in quantum computing, a university press release said.  The …
