The hero is regular matter, which is everything we can see around us. Antimatter is the mirror-image explosive twin that ...

A new computational breakthrough is giving scientists a clearer view into how dark matter structures evolve. Dark matter has remained one of the biggest mysteries in cosmology for almost a hundred ...

A simple explanation of dark matter and antimatter, how they differ, how scientists study them, and why both are important to understanding the universe.

Searches for dark matter particles have come up empty so far, driving theorists to get more creative with their ideas.

In addition, astrophysical observations had revealed that occasionally, white dwarfs would cool off way faster than expected.

In recent years, astronomers have become increasingly interested in a theoretical particle known as the axion, which was ...

Researchers propose a new theory for the origin of dark matter, the invisible substance thought to give the universe its shape and structure. Their mathematical models show that dark matter could have ...

For decades, scientists have speculated about the existence of dark matter, the invisible substance that makes up most of the universe’s mass. Now, thanks to groundbreaking research using NASA’s Fermi ...

The nature of dark matter has confounded scientists for decades, but a new development could help resolve this mystery within the next 15 years. Researchers have developed an "axion quasiparticle" ...
