19 September 2018
Our best theories predict that all the matter in the universe should have been destroyed as soon as it existed. So how comes there’s something, not nothing?

Violent black holes spit neutrinos at Earth and we finally caught one
12 July 2018
For the first time, we have traced a high-energy neutrino back to its origin - a black hole 4 billion light years away - and solved an old cosmic mystery
Antimatter neutrinos caught shape-shifting between flavours
12 June 2018
We’ve seen antineutrinos morphing from one ‘flavour’ to another, and it could help us figure out why the universe is full of normal matter and not antimatter
We see neutrinos from the big bang in the way galaxies cluster
4 April 2018
Just after the big bang, waves of neutrinos and other matter raced across the cosmos. Those neutrinos reached forward in time to dictate where galaxies form now
Mystery of neutrino masses may be explained by dark matter force
16 March 2018
Dark matter and neutrinos are both cosmic loners – they don’t interact with much. But dark matter could give neutrinos their mass through a weak repellant force
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
Neutrinos may have more kinds of cosmic sources than we thought
26 January 2018
Trillions of neutrinos hit Earth each day, but we don’t know where they come from. A new model shows how many may be made in our atmosphere, our galaxy and beyond
Black holes that shred stars burp out cosmic rays and neutrinos
17 November 2017
The highest energy cosmic rays and neutrinos that rain down on Earth may come from white dwarf stars being devoured by black holes
Peek inside a gilded cage of liquid argon made to spot neutrinos
1 November 2017
This huge shiny cube is just a 1/20th scale model of the planned DUNE neutrino detector. It will be filled with liquid argon to catch these elusive particles
Hiding in plain sight: The mystery of the sun's missing matter
18 October 2017
A mass equivalent to 1500 Earths has vanished from the sun. Tracking it down could transform how we see the stars
