For more than a century, gravity has been the stubborn outlier in physics, perfectly described on cosmic scales yet refusing to mesh with the quantum rules that govern everything else. A growing camp ...

When an airplane flies, the wings are designed to provide enough lift to overcome the airplane’s weight, so the plane doesn’t ...

Is gravity a result of differences in informational density? Or is this theory too far out there to address all the issues present in modern physics? Here, we take a look at a recent proposal that ...

The long-range influence of gravity, despite its comparative weakness, stems from its inverse-square law, where its flux remains constant over arbitrary distances due to the compensatory increase in ...
