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 ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. Comtoise watches, as seen here in the Comtoise Museum of master ...

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 ...

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 really depends on the mass of the black hole though. If the sun was replaced by a black hole of the same mass as the sun, then apart from no heat output (and related events, solar wind for example) ...
