A spallation neutron source has been used by physicists in Japan to search for possible violations of the inverse square law of gravity. By scattering neutrons off noble-gas nuclei, the researchers ...

If the universe contains more than three spatial dimensions, as many physicists believe, our current laws of gravity should break down at small distances Nothing seems more certain than the “fact” ...

IN a paper entitled "The Story of Newton's Inverse Square Law and his Use of a False Radius of the Earth" (J. Brit. Astro. Assoc., 50, 2; 1939), John Miller states that the story of Newton's alleged ...

Gravity is the weakest of the fundamental forces, but it’s the only force that operates over very long distances. Hence, planets orbit stars, stars form galaxies, and galaxies cluster. Gravity also ...

Newton devised his universal law of gravitation for planets, but does it work at small scales? A search for a deviation from the expected behaviour could provide the first evidence in support of ...

A “law of nature” is one of those concepts that slips through your fingers the more you try to grasp it. The most that can be said about a physical law is that it is a hypothesis that has been ...
