Cosmon Cosmon or Cosmonium is a hypothetical form of matter where the Universe would have been in a dense form of matter as a particle named Cosmon. The idea was originally proposed by Georges Lemaître who suggested the idea of a 'primeval atom’ ("L'Hypothèse de l'Atome Primitif") 1946. He illustrated the idea by imagining an object 30 times larger than the volume of the sun containing all the matter of the Universe. Its density would be around formula_1. In his view this exploded somewhere between 20–60 billion years ago.

Georges Lemaître Georges Henri Joseph Édouard Lemaître Associate RAS (] ; 17 July 1894 – 20 June 1966) was a Belgian Catholic Priest, astronomer and professor of physics at the Catholic University of Leuven. He proposed the theory of the expansion of the universe, widely misattributed to Edwin Hubble. He was the first to derive what is now known as Hubble's law and made the first estimation of what is now called the Hubble constant, which he published in 1927, two years before Hubble's article.

Polydeism Polydeism (from Greek "πολλοί" (" 'poloi' "), meaning 'many', and Latin "deus" meaning god) is a polytheistic form of deism encompassing the belief that the universe was the collective creation of multiple gods, each of whom created a piece of the universe or multiverse and then ceased to intervene in its evolution. This concept addresses an apparent contradiction in deism, that a monotheistic god created the universe, but now expresses no apparent interest in it, by supposing that if the universe is the construct of many gods, none of them would have an interest in the universe as a whole.

Hypothetical astronomical object A hypothetical astronomical object is an astronomical object (such as a star, planet or moon) that is believed or speculated to exist or to have existed but whose existence has not been scientifically proven. Such objects have been hypothesized throughout recorded history. For example, in the 5th century BCE, the philosopher Philolaus "defined a hypothetical astronomical object which he called the Central Fire", around which he proposed other celestial bodies (including the Sun) moved.

Planck (spacecraft) Planck was a space observatory operated by the European Space Agency (ESA) from 2009 to 2013, which mapped the anisotropies of the cosmic microwave background (CMB) at microwave and infra-red frequencies, with high sensitivity and small angular resolution. The mission substantially improved upon observations made by the NASA Wilkinson Microwave Anisotropy Probe (WMAP). "Planck" provided a major source of information relevant to several cosmological and astrophysical issues, such as testing theories of the early Universe and the origin of cosmic structure; as of 2013, it has provided the most accurate measurements of several key cosmological parameters, including the average density of ordinary matter and dark matter in the Universe.

Noosphere The noosphere ( ; sometimes noösphere) is the sphere of human thought. The word derives from the Greek νοῦς (nous "mind") and σφαῖρα (sphaira "sphere"), in lexical analogy to "atmosphere" and "biosphere". It was introduced by Pierre Teilhard de Chardin in 1922 in his "Cosmogenesis". Another possibility is the first use of the term by Édouard Le Roy (1870–1954), who together with Teilhard was listening to lectures of Vladimir Ivanovich Vernadsky at the Sorbonne. In 1936, Vernadsky accepted the idea of the noosphere in a letter to Boris Leonidovich Lichkov (though he states that the concept derives from Le Roy). Citing the work of Teilhard's biographer—Rene Cuenot—Sampson and Pitt stated that although the concept was jointly developed by all three men (Vernadsky, LeRoy, and Teilhard), Teilhard believed that he actually invented the word: "I believe, so far as one can ever tell, that the word 'noosphere' was my invention: but it was he [Le Roy] who launched it."

Light dark matter In astronomy and cosmology, light dark matter are dark matter weakly interacting massive particle (WIMP) candidates with masses less than 1 GeV. These particles are heavier than warm dark matter and hot dark matter, but are lighter than the traditional forms of cold dark matter. The Lee-Weinberg bound limits the mass of the favored dark matter candidate, WIMPs, that interact via the weak interaction to formula_1 GeV. This bound arises as follows. The lower the mass of WIMPs is, the lower the annihilation cross section, which is of the order formula_2, where "m" is the WIMP mass and "M" the mass of the Z-boson. This means that low mass WIMPs, which would be abundantly produced in the early universe, freeze out (i.e. stop interacting) much earlier and thus at a higher temperature, than higher mass WIMPs. This leads to a higher relic WIMP density. If the mass is lower than formula_3 GeV the WIMP relic density would overclose the universe.

Strong gravity Strong gravity is a non-mainstream theoretical approach to particle confinement having both a cosmological scale and a particle scale gravity. In the 1960s, it was taken up as an alternative to the then young QCD theory by several theorists, including Abdus Salam, who showed that the particle level gravity approach can produce confinement and asymptotic freedom while not requiring a force behavior differing from an inverse-square law, as does QCD. Sivaram published a review of this bimetric theory approach.

Blaise Pascal Blaise Pascal ( ; ] ; 19 June 1623 – 19 August 1662) was a French mathematician, physicist, inventor, writer and Catholic theologian. He was a child prodigy who was educated by his father, a tax collector in Rouen. Pascal's earliest work was in the natural and applied sciences where he made important contributions to the study of fluids, and clarified the concepts of pressure and vacuum by generalising the work of Evangelista Torricelli. Pascal also wrote in defence of the scientific method.

George Gamow George Gamow (March 4 [O.S. February 20] 1904 August 19, 1968), born Georgiy Antonovich Gamov (Russian: Гео́ргий Анто́нович Га́мов ; ] ), was a theoretical physicist and cosmologist. He was an early advocate and developer of Lemaître's Big Bang theory. He discovered a theoretical explanation of alpha decay via quantum tunneling, and worked on radioactive decay of the atomic nucleus, star formation, stellar nucleosynthesis and Big Bang nucleosynthesis (which he collectively called nucleocosmogenesis), and molecular genetics.

Big Bang nucleosynthesis In physical cosmology, Big Bang nucleosynthesis (abbreviated BBN, also known as primordial nucleosynthesis, arch(a)eonucleosynthesis, archonucleosynthesis, protonucleosynthesis and pal(a)eonucleosynthesis) refers to the production of nuclei other than those of the lightest isotope of hydrogen (hydrogen-1, H, having a single proton as a nucleus) during the early phases of the Universe. Primordial nucleosynthesis is believed by most cosmologists to have taken place in the interval from roughly 10 seconds to 20 minutes after the Big Bang, and is calculated to be responsible for the formation of most of the universe's helium as the isotope helium-4 (He), along with small amounts of the hydrogen isotope deuterium (H or D), the helium isotope helium-3 (He), and a very small amount of the lithium isotope lithium-7 (Li). In addition to these stable nuclei, two unstable or radioactive isotopes were also produced: the heavy hydrogen isotope tritium (H or T); and the beryllium isotope beryllium-7 (Be); but these unstable isotopes later decayed into He and Li, as above.

Planck particle A Planck particle, named after physicist Max Planck, is a hypothetical particle defined as a tiny black hole whose Compton wavelength is equal to its Schwarzschild radius. Its mass is thus approximately the Planck mass, and its Compton wavelength and Schwarzschild radius are about the Planck length. Planck particles are sometimes used as an exercise to define the Planck mass and Planck length. They play a role in some models of the evolution of the universe during the Planck epoch.

Neutrino Factory The Neutrino Factory is a proposed particle accelerator complex intended to measure in detail the properties of neutrinos, which are extremely weakly interacting fundamental particles that can travel in straight lines through normal matter for thousands of kilometres. Up until the 1990s, neutrinos were assumed to be massless, but experimental results from searches for solar neutrinos (those produced in the Sun's core) and others are inconsistent with this assumption, and thus indicate that the neutrino does have a very small mass (see Solar neutrino problem).
