The geoid (the surface of equal gravitational potential of a hypothetical ocean at rest) serves as the classical reference ...

Astronomers have long debated why so many icy objects in the outer solar system look like snowmen. Michigan State University ...

Out in the Kuiper Belt, the massive doughnut of debris beyond Neptune, about one in 10 kilometer-scale objects have surprised scientists with their unexpected shape. Rather than resembling a ball, ...

Scientists saw a quark plowing through primordial plasma for the first time, offering a rare look at the first moments after ...

Energy efficiency in physics is not measured the way most people think about it. Instead of asking how much heat a process ...

When an electron travels through a polar crystalline solid, its negative charge attracts the positively charged atomic cores, causing the surrounding crystal lattice to deform. The electron and ...

The research team used two distributed sensors and leveraged two quantum resources for increasing detection sensitivity: ...

The big bang wasn’t the start of everything, but it has been impossible to see what came before. Now a new kind of cosmology is lifting the veil on the beginning of time ...

The total energy of the ball consists of its potential energy (related to position) plus its kinetic energy (related to motion). To zero out both components, you would have to give a precise value to ...

Scientists have used theloudest gravitational wave signal ever recorded to put Albert Einstein’s century-old theory of ...

A record-breaking gravitational wave signal let scientists "listen" to a distant black hole merger and put Einstein's gravity to its toughest test yet.
