Astronomers propose dark dwarfs—objects powered by dark matter annihilation—may exist near the galactic center, offering key clues about WIMPs.

The photoelectric effect, first explained in 1905, transformed our understanding of how light interacts with matter. When ...

We have discovered legions of strange particles that seem to only have a ghostly existence inside materials. Even so, they ...

The deep ocean can often look like a real-life snow globe. As organic particles from plant and animal matter on the surface ...

The unusual radio pulses were detected by the Antarctic Impulsive Transient Antenna (ANITA) experiment, a range of instruments flown on balloons high above Antarctica that are designed to detect radio ...

And there is ordinary matter such as gas, dust, stars, planets and earthly things like cookie dough and canoes.Scientists estimate that ordinary matter makes up only about 15% of all matter, but have ...

In their search for more flavors of Higgs bosons, a team of researchers at CERN stumbled across what could be evidence of the smallest matter-antimatter particle ever. The hypothetical particle ...

It may be the smallest, shortest chorus dance ever recorded. An international team of researchers observed how electrons, excited by ultrafast light pulses, danced in unison around a particle less ...

Some provide the building blocks of matter; others transmit forces between the matter particles, governing how they behave. The Standard Model of particle physics describes nature’s known forces and ...
