Even though we can explore the universe with great precision, there is still a lot we don't know, according to Ulf Danielsson, professor of theoretical physics at Uppsala University. Besides doing ...

A mathematical investigation of galactic data suggests elusive dark matter is confined to the rules of gravity.

At the heart of the Milky Way, just 27,000 light-years from Earth, there is a supermassive black hole with a mass of more ...

How do we know the speed of light – and why does it have a speed limit at all? Leah Crane explores the history of one of the ...

New research suggests dark matter behaves like normal matter under gravity but leaves room for a weak, unknown force.

Scientists have discovered that dark matter, the universe's most mysterious "stuff," obeys gravity on vast cosmological scales. This could help to dismiss the possibility of a fifth fundamental force ...

For years, dark matter has puzzled scientists, lurking in the universe’s vast expanse yet eluding direct detection. This ...

A team of researchers at the Max Planck Institute for Physics in Munich has turned to an unconventional substance in the hunt ...

This quiz dives into the mysterious world of dark matter — what we know, what we don't, and how scientists are chasing shadows across the cosmos. From galaxy rotation curves that defy Newton's laws to ...

Scientists at TU Wien found that electrons need specific “doorway states” to escape solids, not just energy. The insight ...

Astronomers are rethinking one of cosmology’s biggest mysteries: dark energy. New findings show that evolving dark energy models, tied to ultra-light axion particles, may better fit the universe’s ...
