The mass of distant galaxies cannot be determined by the brightness of their stars alone. The speed at which gas moves within ...

・Einstein’s theory of gravity may behave slightly differently across distances of billions of light-years, with gravity appearing about 1 percent weaker on cosmic scales. ・The proposed “cosmic glitch” ...

Why don't we fall off the Earth?We rarely think about gravity in our daily lives.Whether we are getting out of bed in the morning, drinking coffee, or dragging our tired feet home after work, gravity ...

Scientists have spent sixty years arguing over why the quantum weirdness that lets atoms exist in two states at once disappears by the time you get to a cat, a coffee cup, or a person. A new ...

A group of researchers at the University of Waterloo and the University of British Columbia have discovered a potential "cosmic glitch" in the universe's gravity, explaining its strange behavior on a ...

Researchers at Columbia University have found that, under the right conditions, gravitational fields can break and reconnect, ...

Theoretical physicists have long been trying to devise a complete theory of gravity that would also account for quantum mechanics phenomena, as existing models do not. Such a theory could collectively ...

Physicists have found a new mathematical way to connect Einstein’s description of gravity with ideas from quantum physics. The result may help scientists investigate one of the biggest unanswered ...

Scientists have redefined gravity to explain the Big Bang and perhaps change our picture of the earliest moments of the cosmos. This new framework of "quantum gravity" may explain aspects of the Big ...
