CERN: discovery sheds light on the great mystery of why the universe has less ‘antimatter’ than matter
New physics may be needed to explain why there’s more matter than antimatter in the universe.

Dark energy: map gives clue about what it is – but deepens dispute about the cosmic expansion rate
Dark energy is probably a sea of constant energy in empty space itself, according to new research.
How to understand one of Stephen Hawking’s final papers – according to an expert
We may not live in an infinite ‘multiverse’ of parallel universes after all.
Shape of the universe: could it be curved, not flat?
A study has suggested that the universe is curved like a sphere rather than flat, which may unleash a major crisis in cosmology.
From pancakes to soccer balls, new study shows how galaxies change shape as they age
As galaxies get older they get rounder, and fall victim to the middle-aged spread that catches many of us humans here on Earth.
Scientists start mapping the hidden web that scaffolds the universe
Maps of the long filaments of gas that hold the universe together may one day help us trace and unveil ‘dark matter’.
How a ‘muon accelerator’ could unravel some of the universe’s greatest mysteries
When scientists created the Higgs particle with protons, they needed the 10km-wide Large Hadron Collider. A muon machine could achieve it with a diameter of just 200 metres.
The universe’s rate of expansion is in dispute – and we may need new physics to solve it
New observations show we don’t really understand the universe’s expansion.
Experiment picks up light from the first stars – and it may change our understanding of dark matter
New radio technology has managed to detect the first light in the universe.
We need to consider alternatives to dark matter that better explain cosmological observations
Cosmology does not need dark matter or dark energy in an expanding universe that allows the constants of nature to evolve, and light loses energy as it travels vast distances.
