For over 50 years, physicists have generally agreed that the interactions between elementary particles are governed by four fundamental forces: the strong force, weak force, electromagnetic force and ...

Some physicists believe that a fifth fundamental force could be the cause of some observational anomalies. A study is investigating ways to closely examine the trajectories of well-documented ...

There may be a fifth fundamental force of the universe that we haven't documented yet — and, according to new research, our best bet of uncovering it may not lie in deep space, but in objects ...

Matter gets weird at the quantum scale, and among the oddities is the Efimov effect, a state in which the attractive forces ...

In 2016, Earth’s South Pole was struck by a ghostly particle from some unknown corner of the universe. This antineutrino — the neutrino’s antimatter twin — collided with an electron at nearly the ...

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the ...

Dark matter makes up 27 percent of the universe’s total mass and energy — nearly five times more than “normal” matter that comprises planets and stars. True to its name, dark matter is hard to ...

It appears that we live on the knife-edge, where only the narrowest combination of values for the fundamental constants allow life, and especially conscious life, to arise. The fundamental constants ...

This spring, at a meeting of Syracuse University’s quark physics group, Ivan Polyakov announced that he had uncovered the fingerprints of a semi-mythical particle. “We said, ‘This is impossible. What ...
