To live on the moon or Mars, humans will need heat and air conditioning that can operate long term in reduced gravity and temperatures hundreds of degrees above or below what we experience on Earth.

A new discovery suggests gravitational fields can enable matter to become quantum entangled — and that's even if the concept of quantum gravity does not exist. The idea comes from two London-based ...

Despite dozens of experiments over the years, scientists still don't have a precise measurement for gravity's strength. Why is that?

After traveling hundreds of miles above Earth and spending months aboard the International Space Station, a University of Delaware experiment has returned to campus, bringing new data on how ...

We tend not to dwell on the fact that we exist in three dimensions. Forwards-back, left-right, up-down; these are the axes on which we navigate the world. When we try to imagine something else, it ...
