Euclid space telescope has discovered an extremely rare Einstein ring. Einstein rings of light are produced when two galaxies ...

The Euclid space telescope has, by chance, discovered its first Einstein ring, and it is absolutely stunning. Beyond its aesthetic appeal, this perfectly circular Einstein ring has allowed researchers ...

Gravitational potential energy is the energy an object has by virtue of its position above the surface of the Earth. When an object is lifted, work is done. When work is done in raising the height ...

Any object lifted above the ground has gravitational potential energy (\(E_{p}\) or GPE). The amount of gravitational potential energy an object has on Earth depends on its: mass; height above the ...

The quantum and gravitational theory group works on a wide range of topics in theoretical physics, from string theory to quantum information, condensed matter, and cosmology.

When astronomers detected the first long-predicted gravitational waves in 2015, it opened a whole new window into the ...

But scientists are confident it exists because of the gravitational effects it appears ... from the gravity to which we are accustomed. Dark energy is even more mysterious, and its discovery ...

Though astrophysicists think that a high-energy astrophysical process is the likely source of FRBs, they aren't certain how they're generated. Researchers used gravitational waves (GWs ...
