The astonishing result, achieved by the CMS (Compact Muon Solenoid) collaboration, represents the first-ever observation of ...

Physicists have taken the Universe’s temperature, revealing the searing trillion-degree heat of the Big Bang’s first plasma.

The Higgs boson appeared again at the world's largest atom smasher — this time, alongside a top quark and an antitop quark, the heaviest known fundamental particles. And this new discovery could help ...

The early Universe was a strange place. The Universe was so dense and hot that atoms and nuclei could not form—they would be ripped apart by high-energy collisions. Even protons and neutrons could not ...

According to modern particle physics, matter produced when neutron stars merge is so dense that it could exist in a state of dissolved elementary particles. This state of matter, called quark-gluon ...

Creating such a ‘quark soup’ is a tough task in its own right; the first sample of QGP was produced less than two decades ago by smashing two heavy atoms together. But for this new study, which was ...

The universe may contain extremely dense and exotic hypothetical cosmic objects known as strange quark stars. While astrophysicists continue to debate quark stars' existence, a team of physicists has ...

Physicists have found evidence of X particles in the quark-gluon plasma produced in the Large Hadron Collider (LHC) at CERN, the European Organization for Nuclear Research, based near Geneva, ...

When Evan Coleman was wrapping up his undergraduate studies in physics at Brown University, he wanted to find something special to give his mentor, Meenakshi Narain. “How do you get a gift for someone ...

I woke up this morning to various emails and tweets saying that I’ve just won the 3 Quarks Daily Science Prize for 2010. Monday mornings don’t usually start this promisingly! For those who haven’t ...
