Fundamental forces of nature: Gravity. Gravity is the attraction between two objects that have mass or energy, whether this is seen in dropping a rock from a bridge, a planet orbiting a star or ...

According to standard model, the strength of electromagnetism - one of the four fundamental forces of nature - should be constant throughout the cosmos, but Webb and colleagues have found otherwise.

The other is the Standard Model, which we use to describe the other three forces of nature: electromagnetism, the strong nuclear force and the weak nuclear force.

At a fundamental level, our Universe is made of particles, forces, interactions, and the fabric of space and time. Spacetime forms the ever-evolving stage on which the play of the cosmos unfolds ...

All told, there are about two dozen such numbers. They express such basic facts as the speed of light, the strength of the four fundamental forces, and the masses of elementary particles.

If gravity is the weakest of the four fundamental forces, ... (which relates to its strength) crossing a surface area. Let’s think of an imaginary sphere with the Sun at the center.

Mysterious forces may be a reliable trope in science fiction, but in reality, physicists have long agreed that all interactions between objects evidently arise from just four fundamental forces.

Researchers at the Kastler Brossel Laboratory in Paris have made the most precise measurement of one of the fundamental constants, called the fine-structure constant, providing physicists with a ...

Protons sit in the nuclei of all atoms, but they are not fundamental particles: They are made of three quarks held together by the strong nuclear force.The strength of this interaction is actually ...
