The Standard Model is a gauge theory that describes the strong, weak, and electromagnetic forces, and it has specific ...

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak ...

Weight is a force due to the pull of gravity on an object. Weight is a force and so is measured in newtons (N). Weight is the force acting on an object due to gravity - it has the unit newtons (N ...

Gravitational forces that make things fall down to the ground – unless another force stops them. An apple falling from a tree falls straight down. A ball thrown up, comes back down. And so do we ...

Researchers have developed a new quantum theory of gravity which describes gravity in a way that's compatible with the Standard Model of particle physics, opening the door to an improved understanding ...
