The most precise measurement yet shows the Universe is expanding faster than expected, deepening the Hubble tension. The ...

A comprehensive new study combines decades of research to reveal that we're missing an essential component in our understanding of how the universe works.

This graphic illustrates the preferred mass values for new particles (labeled rho and kappa scalars) that extend the SM scalar spectrum in our setup. As shown, past lepton colliders (LEP) and the ...

The difference is like a crowd of people who ignore each other versus one where everyone is constantly bumping into one another,’ says scientist ...

For more than a century, physics has been built on two great theories. Einstein's general relativity explains gravity as the bending of space and time. Quantum mechanics governs the world of particles ...

A major international effort has produced an ultra-precise measurement of the Universe’s expansion rate, confirming it’s ...
