From 19 to 22 January, 80 particle physicists, astronomers and cosmologists gathered at CERN for the first “All that ...

Michael S Turner argues that the next breakthrough in particle physics and cosmology may be just around the corner.

Shaped by a different biology or culture, other intelligent civilisations – if they’re out there – might understand the ...

Over 85 years after it began, the Einstein-Bohr debate remains the most consequential intellectual rivalry in modern science ...

About 13.8 billion years ago, the origin of the universe began with the Big Bang. Scientists say all space, time, matter, and ...

Neutron stars harbor some of the most extreme environments in the universe: their densities soar to several times those of ...

There’s a worrying problem with the ‘Higgs field’ – the energy field that gives particles their mass. It seems to be dangerously close to having an inherent instability. In the absence of particles, ...

Looking for molecular evidence of life on other worlds is tricky, but a test based on the reactivity of carbon compounds ...

Astronomers have long known the universe is expanding—but exactly how fast remains one of the biggest mysteries in cosmology. Different techniques for measuring the Hubble constant stubbornly disagree ...

Ripples in the fabric of space-time called gravitational waves may be the key to solving the Hubble tension — one of the biggest nagging problems in physics.

Maria Goeppert Mayer is remembered as one of the most important physicists of the twentieth century. She was born in Germany ...

For decades, the Standard Cosmological Model has operated on a single, foundational assumption: the Big Bang happened everywhere at exactly the same time. Today, a newly released theoretical paper ...
