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 ...

It’s a fundamental principle of physics that particles with opposite charges attract each other, while those with the same charge repel. But now, scientists at the University of Oxford have found that ...

It could rock the very foundations of modern science. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Just four numbers underpin the laws of ...

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 ...

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 ...

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 ...
