A class of University of Texas astronomy students has discovered that nearby dwarf galaxy Segue-1 seems to host a ...

An international team of researchers led by the Leibniz Institute for Astrophysics Potsdam (AIP) has shed light on a ...

No experiment has yet measured the speed of gravity, but that hasn’t prevented theorists from coming up with some answers. According to Newton, gravity acts instantly — that is, “action at a distance” ...

Quanta Magazine: Stacy McGaugh, professor and chair of the Department of Astronomy in the College of Arts and Sciences, discussed an alternative theory of gravity—a tweaked version of Einstein’s ...

General relativity, Einstein's theory of gravity, is a purely classical theory that describes gravity as the warping of space-time geometry by mass and energy. But attempts to blend quantum theory ...

Human health is the Achilles heel of space travel. Researchers at ETH Zurich have now succeeded in printing complex muscle ...

Small and unassuming, Segue 1 is a nearby dwarf galaxy containing only a handful of stars—too few to provide the gravity ...

Earth and the Moon are forever locked in a gravitational embrace that has played a critical role in determining the fate of both worlds. Although they have grown more distant since their formative ...

A Harvard astrophysicist has stirred debate in the scientific community after suggesting that the mysterious interstellar ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.
