A conspiracy theory that spread on social media claims that gravity will disappear for seven seconds this August, and that NASA is aware that this will happen. A physics professor explains why this is ...

A theoretical proposal published in the journal Reports on Progress in Physics is making some bold claims about our previous understanding of quantum physics. Mainly, that we were wrong. The proposed ...

We don't know what gravity is. Say that to the average person, and the answer you'll probably get is some version of: "What are you talking about? Gravity is the force of attraction that makes things ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. More than 100 years after Albert Einstein first outlined his ideas ...

Lots of people, including Einstein (see above), talk about gravity, the restraining force which makes people walk on floors instead of floating in midair. What worries Roger Babson, 74, economic ...

They say there aren’t movie stars anymore. Sandra Bullock’s performance in Gravity would beg to differ. The sci-fi film is basically a two-hander between the star and the director. And yet, in an era ...

If you take away all air resistance, a hammer and a feather will fall down at the same rate – that’s the nature of gravity as expressed by Einstein’s Theory of Relativity. It’s a concept that was ...

For more than a century, gravity has been the stubborn outlier in physics, perfectly described on cosmic scales yet refusing to mesh with the quantum rules that govern everything else. A growing camp ...

Once again, physicists have confirmed one of Albert Einstein's core ideas about gravity — this time with the help of a neutron star flashing across space. The new work makes an old idea even more ...

Physicists are using analog black holes to better understand gravity. A0620-00, a binary star system 3300 light-years away, holds a dark secret: One of its stars isn’t a star at all, but a black hole.
