Physicists are eyeing charged gravitinos—ultra-heavy, stable particles from supergravity theory—as possible Dark Matter candidates. Unlike axions or WIMPs, these particles carry electric charge but ...

Physicists have devised a new model to account for the discomfort that airline passengers know all too well. By Alexander Nazaryan Bjorn Birnir dreads an airplane seatmate asking what he does for a ...

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 ...

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.

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 ...

Scientists propose a bold test of string theory by identifying a hypothetical five-particle family, called a 5-plet, that string theory cannot produce. If such a particle were found at the LHC, it ...
