What we saw in the DESI experiments, and now strengthened by our South Pole Telescope observations, is that dark energy is ...

When a researcher from the University of Arizona in Tucson announced on August 21 that his team had "direct proof of dark matter's existence," it seemed the issue had been settled. Now proponents ...

The mysterious substance known as dark matter may actually be an illusion created by gravitational interactions between short-lived particles of matter and antimatter, a new study says. Dark ...

Dark matter could have an invisible “periodic table,” study suggests — but it's still elusive A new theory of the universe’s most mysterious particle peeks into mind-bending “bubbles ...

DW. Is there definitive proof that dark matter exists? Posted: March 27, 2025 | Last updated: March 27, 2025. Everything we see is just a fraction of the universe.

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 ...

In the dark-matter paradigm, you can’t predict the velocities based on the presence of dark matter. Instead, you have to measure the galaxy’s rotation curve to infer how much dark matter is present.

A proof of concept. The BREAD detector searches for a specific subset of possibilities. It’s built to look for dark matter in the form of what are known as “axions” or “dark photons”— particles with ...

While it’s not iron-clad proof that axions are dark matter, the implications for axions are strong. Proving that they are the “stuff” of dark matter will take more observations.
