Though spacecraft with artificial gravity are still a distant dream, we had proof of concept way back in September 1966.

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.

Explore 25 science experiments that defied the laws of physics, revealing mind-bending phenomena that challenge intuition.

Gravity is the force of action between two objects. It’s called a natural force because it acts at a distance rather than needing to be in contact. Gravity is the force that holds us down on Earth and ...
