A "cosmic CT scan" performed by scientists using two very different cosmic surveys has revealed the cosmos is less clumpy and ...

Gravity has shaped our cosmos ... DESI is a state-of-the-art instrument that can capture light from 5,000 galaxies simultaneously. DESI is mounted on the U.S. National Science Foundation's ...

Capturing images of individual stars in distant galaxies has generally been considered impossible for decades. But NASA’s ...

For example, pictures of galaxies that include strange rings and arcs of light could be explained if ... by fundamentally modifying our theories of gravity. According to such ideas, there are ...

The problems of gravity and acceleration would not go away ... Furthermore, if you were in the elevator accelerating upward and a beam of light entered the elevator parallel to the floor, the ...

Black holes are points in space that are so dense they create deep gravity sinks. Beyond a certain region, not even light can escape the powerful tug of a black hole's gravity. And anything that ...

Some objects fall differently depending on how gravity and air resistance interact. A feather, for example, is light and has a large surface area, meaning it will fall to the ground slowly.

Quantum gravity, on the other hand ... distance limits in moduli space are associated with the emergence of light states and the breakdown of effective field theories[1][2].
