Gravity is, at heart, a mystery. Yes, we can talk about curvature of space-time and perhaps make analogies with stretched rubber sheets. But we don’t know why mass causes space-time to curve. To put ...

In the effort to unify the gravitational theory of general relativity with the quantum theory of the very small theoretical physicists explore a lot of wild ideas. One of these is the idea of higher ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. To unpack these a bit, Karl Popper was the philosopher of science who I ...

Charles Sanders Peirce, a practicing scientist and proponent of philosophical pragmatism, began the gravity program of the U.S. Coast and Geodetic Survey in the early 1870s, at a time when his father ...

Despite more than 200 years of experiments, the best laboratory determinations of the force of gravity have yielded no better than a ballpark figure. Adding to the haziness, metrologists have scarcely ...

It’s been 120 years since Henry Cavendish measured the gravitational constant with a pair of lead balls suspended by a wire. The fundamental nature of gravity still eludes our best minds - but those ...

A Twizzlers-themed ride will join the Hersheypark skyline next summer, and it's being referred to as the "tallest Screamin' Swing in the world." The pendulum attraction called Twizzlers Twisted ...
