kvantna gravitacija

kvantna gravitacija

At very small distances, the principles of quantum mechanics are necessary to accurately describe physical phenomena. Developing a theory that incorporates both the principles of quantum mechanics and gravity, a theory of "quantum gravity", has proven to be extremely difficult. String theory is the first real hope of providing such a theory.

Chemistry; General chemistry

A branch of physics that describes the behavior of objects of atomic and subatomic size.

kvantna mehanika

Physics; General physics

Model of the atom based on the wave nature of subatomic particles, the mechanics of electron waves; also called wave mechanics.

kvantna mehanika

Physics; Particle physics

In microscopic systems, particles such as electrons and protons behave like waves. Quantum mechanics replaces the more familiar Newtonian mechanics to describe such phenomena.

Physics; Particle physics

A theory that seeks to incorporate a quantum theory of gravity into the Standard Model. In this theory, the fundamental constituents of matter are not particles, but strings. The ...

supernova

Physics; Particle physics

When a star exhausts its nuclear fuel, it under goes a catastrophic collapse. The resulting explosion is known as a supernova. It often is brighter than an entire galaxy.

super čestica

Physics; Particle physics

Supersymmetry predicts the existence of superpartners of the Standard Model particles. These new types of particles, the superparticles, would represent a new quantum dimension.

Astronomical measurements indicate that luminous matter, such as our sun, makes up only a small percentage of the total matter in the universe. The missing mass that makes up the ...

simetrija

Physics; Particle physics

Physicists use symmetries to restrict possible theories of fundamental particles. As an analogy, consider the human face. If you were able to see only the right side of a person's ...
