The original waves. In 1924, French physics doctoral student Louis de Broglie proposed that matter has a wave-like property. De Broglie was inspired by the discovery of wave-particle duality in light.

The latest experiment also represents the first time the LZ team applied a technique called “salting,” in which false WIMP ...

These particles are thought to be responsible for so-called dark matter, the catch-all term for the 27% of stuff in the universe that has not been directly observed, but whose presence is seen in ...

But axions were pushed aside as the WIMPs hypothesis gained more steam. Back-of-the-envelope calculations showed that the ...

And while many sophisticated experiments have been searching for WIMPs, no definitive trace has turned up—leading some scientists to wonder if dark matter may be made of something else altogether.

The prevailing idea regarding dark matter is the cold dark matter theory (CDM), which posits that dark matter is made up of low-velocity particles that do not interact with each other.

While the Broadband Reflector Experiment for Axion Detection (BREAD) developed by the University of Chicago and the U.S. Department of Energy's Fermilab hasn't turned up dark matter particles just ...

And now, they’ve managed to prove that a theory first shared 70 years ago was correct, and we really can create matter out of absolutely nothing. The universe is made up of several conservation ...

To be wavelike suggests that dark matter is ultralight—a millionth or even billionth the mass of an electron. From cosmological observations, scientists have an estimate of the total mass of all dark ...

The ancient Greek philosopher Democritus imagined all matter to be made of tiny particles, perfectly solid and totally indivisible. Falling through empty space, these atoms, Democritus believed ...

The four fundamental states of matter are solid, liquid, gas and plasma, but there others, such as Bose-Einstein condensates and time crystals, that are man-made.

Nov. 8, 2011, was a special day for the Italian physicist Guido Tonelli. Not only was it his 61st birthday but he had also been tasked with announcing an exciting discovery made at the Large ...
