Could a reactionless, gravity-defying propulsion system actually work? A former NASA engineer says yes, but scientists are ...

This new propulsion system could rewrite the rules of spaceflight—not to mention completely defy conventional physics.

Gravity is the force that keeps our feet on the ground ... masses which give the feel of what 1kg would feel like on different planets. This could then lead on to worked examples of the formula ...

Dicke of Princeton has a different theory ... By his guess, the force of gravitation is about 13% less today than when the earth was formed 4½ billion years ago. Why gravitation should be ...

This concept reframes gravity using quantum relative entropy, a measure that quantifies how different two quantum ... itself ...

"The idea is very simple yet remained unnoticed all this time. If gravity is quantum, as a long-range force, it should be ...
