Einstein said the effect of gravity was due to the curvature of space rather than a conventional force like electromagnetics that is mediated by a particle called the photon. Some theories try to make ...

(via Sabine Hossenfelder) Just exactly what does it mean that gravity is not a force? In this video I will revisit the question and explain why you are currently accelerating upwards, and how Einstein ...

The search for quantum gravity is the next big step in physics, as researchers seek to unify the physics of the very small ...

A mathematical investigation of galactic data suggests elusive dark matter is confined to the rules of gravity.

In the zero-gravity airplanes or vomit comet, why does stuff behave like there is no gravity when it is just falling? – Austin B., 11, Scranton, Pennsylvania I have flown many times in zero-gravity ...

The universe holds many mysteries, but none as elusive, or abundant, as dark matter. Dark matter makes up around 85 percent of all matter in the universe and about 27 percent of its total mass, ...

Some people watch science fiction shows to be entertained, and that's fine. But you can also use them to find excellent physics problems. How about the recent Netflix movie Stowaway? It's about a crew ...
