A new three-volume study explores how quantum physics, gravitation and cosmology may be understood within a unified ...

How can the Universe be expanding at two distinct rates? This enigma, named the Hubble tension, has puzzled astronomers for several years. The origin of this tension lies in the discrepancy ...

Deep canyons in the Andes are the perfect location to catch the most energetic particles in the universe. Carlos ...

A single particle cut through the Mediterranean in February 2023 carrying an almost absurd amount of energy. Detected deep ...

The search for the origin of a mysterious ultra-energetic cosmic neutrino detected in 2023 may have finally reached a ...

Neutrinos are often known as "ghostly particles", and for good reason. There are trillions literally going through each of us right now. They occasionally slam into matter, producing flashes of light ...

Three years ago, in the waters of the Mediterranean Sea, the passage of an "ultra-energetic" cosmic neutrino was observed—the ...

Scientists propose a gravitational-wave method called the stochastic standard siren to measure the Hubble constant, offering an independent way to examine the universe’s expansion and the Hubble ...

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.

Astronomers are exploring a new way to measure the universe’s expansion rate using the gravitational-wave background detected ...
