How can some galaxies survive with so few stars? The answer could be dark matter.
Modified Gravity Need Not Apply
An alternative to dark matter seemed to better describe the rotation of galaxies, but new research shows dark matter works just as well.
The Dark Web
A study of thousands of galaxy pairs shows dark matter filaments exist between galaxies.
Black Holes And Dark Matter
We haven’t completely ruled out black holes as the source of dark matter, but there are few mass ranges left.
Evidence Of Absence
Dark matter may exist, but it doesn’t emit gamma rays.
Emergence Of Gravity
A new solution to dark matter argues that gravity is not a fundamental force, but rather an emergent property of entropy.
Galactic Motion Challenges Dark Matter
New research on galaxy rotation casts a shadow on dark matter.
Dark Beginnings
The history of dark matter spans more than a century, and continues to raise interesting questions.
Dark Matter, Dark Photons, And The Fifth Force
Have we discovered a fifth fundamental force?
