ST. LOUIS ? Quark stars, exotic objects thathave yet to be directly observed, are part of a new theory to explain some ofthe brightest stellar explosions recorded in the universe.

University of Chicago scientists have solved a 20-year-old puzzle in particle physics using data from an experiment conducted for an entirely different purpose. Physicists had long known that ...

For a large star, death is a bit of a squeeze. Once its nuclear fuel is spent, its core collapses, sparking a dramatic supernova explosion that blasts away the outer layers. The body left is a cold, ...

Thanks to a new development in nuclear physics theory, scientists exploring expanding fireballs that mimic the early universe have new signs to look for as they map out the transition from primordial ...

Recreating the conditions present just after the Big Bang has given experimentalists a glimpse into how the universe formed. Now, scientists have begun to see striking similarities between the ...

The supercollider is now being used to explore quantum phenomena, including a “magic” form of quantum entanglement.

Three American physicists shared the $1,3-million Nobel prize for physics for calculating the bizarre properties of the ultimate fragments of matter. They provided the mathematics for a completely new ...

Quarks are the smaller-than-a-proton particles without which there would be no stars, dogs, or breakfast burritos. In 1986, after a dozen frustrating years of trying to find ways of using computers to ...

THERE is something the matter with matter. Around the world, several research groups have reported seeing a particle that does not fit comfortably with our standard picture of matter. As if that ...
