If another gravity theory is correct, "then the broader implications are enormous," astrophysicist Stacy McGaugh told ...

Gravitational distortions produced by distant galaxies show a slight—but notable—disagreement with Einstein's predictions.

Gravity waves instead form at the interface of two fluids or between two regions of the atmosphere with different properties.

The Earth, for example, is massive enough for the force due to gravity to be noticed. Some objects fall differently depending on how gravity and air resistance interact. A feather, for example ...

Lithophanes are nothing new, with examples going back to the 1800s ... of thinking that lead [The Mad Maker] to recreate animated GIFs with stop motion photography and a stack of printed lithophanes.

A GIF image that gradually comes into focus. Instead of displaying a line at a time from top to bottom, lines at various intervals throughout the frame are displayed until all the lines are filled in.

But gravity only becomes noticeable when you have at least one very big mass (a planet for example). No, the distance is squared in the equation so it would have nine times the force (a third of ...

If gravity is a truly quantum entity, something as simple as measuring the strength of an object’s gravitational field should change its quantum state ...

This means that their gravitational pull is immense, for example, on the surface of a neutron star gravity is around 1 billion times stronger than its pull on Earth. This makes neutron stars a ...

Here are eight examples of mutualistic relationships. True gobies (Gobiidae) are a family of about 2,000 species of fishes. Most of them are quite small and live on the seafloor. In some cases, gobies ...

But still: That’s a lot of mainstream movies that play somewhere between knock-off of Gravity and pared-down slasher film, isn’t it? And Gravity came out over a decade ago; why do these movies ...

The Last Dance’ races through action and exposition at breakneck speed. Things simply happen, one after another, with no ...
