kosmički zraci

kosmički zraci

Any of the particles from outer space that are continuously colliding with the Earth's atmosphere. They are mostly protons, with some nuclei, electrons, and photons. Their interactions with the atmosphere produce a variety of particles, including pions, muons, and neutrinos.

Saistītie termini

x-zraci

Astronomy; Mars

Very short wavelength radiations beyond the ultraviolet in the spectrum, which are about one ten-thousandth as long as the visible violet and are extremely penetrating.

x-zraci

Art history; Visual arts

A photograph using an x-ray. X-ray images have been used to identify what lies under the surface of a painting, including prior works or studies and sketches.

X-zraci, rendgenski zraci

Chemistry; General chemistry

A very high energy form of electromagnetic radiation (though not as high energy as gamma rays ). X-rays typically have wavelengths from a few picometers up to 20 nanometers. ...

gama zraci

Chemistry; General chemistry

A very high energy form of electromagnetic radiation , typically with wavelengths of less than 3 pm. Gamma rays are produced by certain nuclear decay processes, and are used to ...

teorija struna

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.

supersimetrija

Physics; Particle physics

A hypothetical symmetry relating particles of different spins. Under this symmetry, matter particles (spin one-half fermions) are related to force particles (spin-zero or spin-one ...

tamna materija

Physics; Particle physics

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 ...
