Dark radiation may fix our broken understanding of the universe
20 March 2018
We have two ways to measure the accelerating expansion of the universe, but they don’t line up. If dark matter gives off radiation, it could make them agree
Dark matter could be produced by twisted gravitational waves
9 February 2018
If gravitational waves – ripples in space time – have a handedness, primordial particles could interact with them to form a dark matter superfluid that spreads through the cosmos
Parallel universes could solve a big problem with black holes
20 December 2017
The black hole firewall paradox has been vexing physicists for years. But if quantum laws lead to the creation of other universes, the headache disappears
Dark energy survives neutron star crash test while rivals fail
20 October 2017
We saw gravitational waves and light at the same moment from a neutron star merger, which means Einstein was right and some alternative theories are dead
Far-off galaxies are firing rare high-energy cosmic rays at us
21 September 2017
The highest energy particles in the universe hit Earth very rarely, so it took 10 years of data to pinpoint their origin. They’re coming from galaxies far, far away
