Dark matter may consist of two particles, explaining why only the Milky Way shows a strange gamma-ray signal while smaller ...

Joseph Shavit The absence of a signal could itself be a signal. This is the idea behind a new study published in the Journal ...

Its ratio differs from the Milky Way to dwarf galaxies.

Dark matter constitutes one of the great mysteries of modern cosmology. Invisible yet omnipresent, it shapes galaxy formation ...

A dark matter signal that appears in one place but not another might look like a contradiction. This new study argues it may ...

A new study suggests that faint, ancient ripples in spacetime may hold the key to one of physics’ greatest mysteries.

A new hypothesis has been proposed suggesting that 'dark matter,' a concept that explains the birth of the universe and the ...

A black hole is more than just a region of space where nothing escapes. It can also become a powerful cosmic engine. When matter spirals inward, falling into its grasp, the black hole doesn't just ...

A bizarre, record-breaking neutrino detected in 2023 may have originated from an exploding primordial black hole—a relic from ...

For more than a century, physics has been built on two great theories. Einstein's general relativity explains gravity as the bending of space and time. Quantum mechanics governs the world of particles ...

A study by Dartmouth researchers proposes a new theory about the origin of dark matter, the mysterious and invisible substance thought to give the universe its shape and structure. The researchers ...

Learn how a two-state model of dark matter could explain why gamma-ray signals appear in some galaxies but not others.
