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 ...

But here’s the catch: the theory fails to explain why some materials, like high-temperature superconductors, maintain their ...

The universe’s first moments after the Big Bang were strange beyond imagination. Now physicists have discovered they may have been even weirder than we thought, dominated by enormous, twisted knots of ...

For various, typically historical reasons, even the best physicists claim things that sound egregious to modern observers. That doesn’t necessarily mean these ideas are completely useless—if anything, ...

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.

Crucially, physicists haven’t been able to think of any such process that would mesh with today’s leading theory of matter and energy, known as the Standard Model of particle physics. That leaves ...
