The models work by eliminating gravity, and one dimension—either time, or a dimension of space—to simplify the calculations. It’s just unclear whether those holographic models will ultimately prove to ...

Space.com's reporter Tereza Pultarova takes part in a research flight simulating lunar gravity in this original documentary.

Experiencing low gravity for the first time isn't for the faint of heart. To share the experience, Space.com is releasing a brand new documentary "Walking on the moon at 30,000 feet! Space.com ...

Hit film 'Gravity' launches some eyebrows among space industry professionals for scientific accuracy — but they still like it.

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 ...

We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole new model to account for gravity’s influence.

A physicist claims that gravity is not a force holding life together, but that it is actually a clue that we live in a simulation.

Any theory of quantum gravity is going to have to grapple with some weird time stuff.

In the April 1981 issue of Popular Science, we explored the many initiatives and techniques used in the hunt for gravity waves.
