The positron or antielectron is the particle with an electric charge of +1e, a spin of 1/2, and the same mass as an electron. It is the antiparticle of the electron. When a positron collides with an electron, annihilation occurs. If this collision occurs at low energies, it results in the production of two or more photons.
A supernova remnant (SNR) is the structure resulting from the explosion of a star in a supernova. The supernova remnant is bounded by an expanding shock wave, and consists of ejected material expanding from the explosion, and the interstellar material it sweeps up and shocks along the way.
Degeneracy, degenerate, or degeneration may refer to:
Form is the shape, visual appearance, or configuration of an object. In a wider sense, the form is the way something happens.
Spiritual is the adjective for spirit.
The Big Crunch is a hypothetical scenario for the ultimate fate of the universe, in which the expansion of the universe eventually reverses and the universe recollapses, ultimately causing the cosmic scale factor to reach zero, an event potentially followed by a reformation of the universe starting with another Big Bang. The vast majority of evidence indicates that this hypothesis is not correct. Instead, astronomical observations show that the expansion of the universe is accelerating rather than being slowed by gravity, suggesting that a Big Chill is more likely. However, there are new theories that suggest that a "Big Crunch-style" event could happen by the way of a dark energy fluctuation; however, this is still being debated amongst scientists.
Quintessence, or fifth essence, may refer to:
The Aetherius Society is a new religious movement founded by George King in the mid-1950s as the result of what King claimed were contacts with extraterrestrial intelligences, to whom he referred as "Cosmic Masters". The main goal of the believer is to cooperate with these Cosmic Masters to help humanity solve its current Earthly problems and advance into the New Age.
Cosmic entity can refer to:
Oh My God, O My God, Oh My God! or Ohmigod may refer to:
Cosmic commonly refers to:
Nuclear astrophysics is an interdisciplinary part of both nuclear physics and astrophysics, involving close collaboration among researchers in various subfields of each of these fields. This includes, notably, nuclear reactions and their rates as they occur in cosmic environments, and modeling of astrophysical objects where these nuclear reactions may occur, but also considerations of cosmic evolution of isotopic and elemental composition (often called chemical evolution). Constraints from observations involve multiple messengers, all across the electromagnetic spectrum (nuclear gamma-rays, X-rays, optical, and radio/sub-mm astronomy), as well as isotopic measurements of solar-system materials such as meteorites and their stardust inclusions, cosmic rays, material deposits on Earth and Moon). Nuclear physics experiments address stability (i.e., lifetimes and masses) for atomic nuclei well beyond the regime of stable nuclides into the realm of radioactive/unstable nuclei, almost to the limits of bound nuclei (the drip lines), and under high density (up to neutron star matter) and high temperature (plasma temperatures up to 109 K). Theories and simulations are essential parts herein, as cosmic nuclear reaction environments cannot be realized, but at best partially approximated by experiments. In general terms, nuclear astrophysics aims to understand the origin of the chemical elements and isotopes, and the role of nuclear energy generation, in cosmic sources such as stars, supernovae, novae, and violent binary-star interactions.
In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object.
Shakti is the fundamental cosmic energy and a central deity within Shaktism, a significant theological tradition of Hinduism. Representing dynamic forces that permeate the universe, Shakti embodies feminine energy and is often depicted as the consort of Shiva. In this tradition, Devi, the Goddess, is regarded as the Supreme Brahman herself, with all other divine forms seen as her manifestations. The worship of Shakti entails a diverse array of goddesses, including Durga, Kali, Parvati, and Tripura Sundari, each representing unique facets of her power.
The Universal White Brotherhood (UWB) is a religious movement founded in Bulgaria in 1897 by Peter Duenow. It was later established in France in 1937 by Omraam Mikhaël Aïvanhov, one of Deunov's followers.
The zero-energy universe hypothesis proposes that the total amount of energy in the universe is exactly zero: its amount of positive energy in the form of matter is exactly canceled out by its negative energy in the form of gravity. Some physicists, such as Lawrence Krauss, Stephen Hawking or Alexander Vilenkin, call or called this state "a universe from nothingness", although the zero-energy universe model requires both a matter field with positive energy and a gravitational field with negative energy to exist. The hypothesis is broadly discussed in popular sources. Other cancellation examples include the expected symmetric prevalence of right- and left-handed angular momenta of objects, the observed flatness of the universe, the equal prevalence of positive and negative charges, opposing particle spin in quantum mechanics, as well as the crests and troughs of electromagnetic waves, among other possible examples in nature.
Cosmic Force may refer to:
Transient High-Energy Sky and Early Universe Surveyor (THESEUS) is a space telescope mission proposal by the European Space Agency that would study gamma-ray bursts and X-rays for investigating the early universe. If developed, the mission would investigate star formation rates and metallicity evolution, as well as studying the sources and physics of reionization.
