As much as we wish this was some type of anti-gravity bouncy castle, NASA's current experiments with inflatable structures are intended for slightly less entertaining implementation on the moon, where crews will use them as outposts for research, testing, storage, and living.

This new type of regulator was developed in response to a longstanding problem: the detrimental effects of gravity on the regularity of a movement by generating variations in rate.

Equally importantly, the Higgs allows two of the four forces in nature -- the electromagnetic force and the weak force, which is responsible for most nuclear reactions -- to be unified and described by mathematics of the same type that describe the other two known forces, the so-called strong force and gravity.
