Discovery of Dark energy

Discovery of Dark energy

In 1998, two teams of astronomers discovered that, instead of slowing down, the universe is expanding faster today than it was in earlier epochs Adam Riess Adam Riess thought there must have been a mistake. In late 1997, he was analyzing observations of exploding stars to help determine whether the universe…

Universal of Gravitation

Universal of Gravitation

Physics is based on the assumption that certain fundamental features of nature are constant. Some constants are considered to be more fundamental than others, including the velocity of light c and the Universal Gravitational Constant, known to physicists as Big G. Unlike the constants of mathematics…

Value of universal gravitational constant

A set of 13 measurements of G exhibit a 5.9-year periodic oscillation (solid curve) that closely matches the 5.9-year oscillation in LOD measurements (dashed curve). The two outliers are a 2014 quantum measurement and a 1996 measurement known to suffer from drift. The green dot is an estimate of the…

Force of gravity on Earth

Force of gravity on Earth

Gravity is one of those things we take completely for granted. And there are two things about it that we take for granted: the fact that it is always there, and the fact that it never changes. If the Earth s gravity were ever to change significantly, it would have a huge effect on nearly everything because…

Searching for dark matter

Searching for dark matter

Experiments at the Large Hadron Collider specialize in the discovery of previously undetected particles. So of course they are on the hunt for one of physics’ most coveted prizes: dark matter. Dark matter outnumbers visible matter—the kind of matter that makes up the Earth, the stars and all of us—five-to-one…
