Definition of Compton effect

Compton effect is the name of a phenomenon that was studied in 1923 by Arthur Compton, an American physicist who made valuable scientific contributions. In 1927, this expert who had X-rays as an object of interest and discovered that a photon, upon colliding with a free electron and losing a portion of energy, […]

Definition of boson

Boson is a term used in the field of particle physics that identifies an elementary particle capable of exerting an interaction involving fermions. In this context, it is worth remembering that a fermion is also one of the elementary particles, in this case with the particularity that its spin only […]

Definition of cosmic inflation

Cosmic inflation is a hypothesis in cosmology that postulates that the universe experienced accelerated expansion during the first moments of its existence, in a fraction of a second after the Big Bang, when the universe was still extremely dense and hot. During this brief period of inflation, the universe would have experienced exponential expansion, […]

Definition of galaxy clusters

Galaxy clusters are enormous structures, among the most colossal in the universe, where between five and a hundred dozen galaxies are grouped together and retain their unity due to the action of gravity. There is also dark matter in this network and a very high-temperature plasma defined by astronomers as intracluster gas (ICM) that […]

Definition of gravitational lens

Gravitational lens is a notion, also known as gravitational lens, that is present in the field of astrophysics. It is a concept intended to describe a phenomenon that arises when a beam of light coming from various bright and distant objects is curved around a massive object (such as the case […]

Definition of Kepler's laws

There are three Kepler laws and they pay tribute in their name to a German mathematician and astronomer named Johannes Kepler. He, many years ago (between 1609 and 1619), was in charge of formulating the statements that allow us to establish the movements that the planets make in their orbits around the sun. […]

Definition of stellar evolution

Stellar evolution is the expression that refers to the transformations that occur in stars over the years. As time passes, each star experiences changes in its external appearance, in addition to modifications in its internal structure. As researchers specialized in astronomy have been discovering, there are phenomena […]

Definition of extraterrestrial life

Extraterrestrial life is an expression that refers to all that existence that, according to many people, has originated and subsists (at least hypothetically) outside our planet, Earth. Those who are dedicated to observing the universe and try again and again to solve mysteries linked to the galaxy guide some of their […]

Definition of multiverse

Multiverse is a concept that refers to the set of parallel universes that, according to various hypotheses, coexist alongside ours. Scientists believe that the multiverse contains everything that has physical existence: from all forms of energy, matter and momentum to all time and […]

Definition of weak nuclear force

The weak nuclear force is, as seen when gathering information related to particle physics, one of the fundamental interactions that can be recognized when analyzing the behavior of subatomic particles. The other forces are gravity, the electromagnetic force, and the strong nuclear force. This weak interaction, physics experts point out […]
