Question: 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, was a Belgian Catholic Priest, astronomer and professor of physics at the Catholic University of Leuven, in what year?
Context: In cosmology and physics, cold dark matter (CDM) is a hypothetical form of dark matter whose particles moved slowly compared to the speed of light (the "cold" in CDM) since the universe was approximately one year old (a time when the cosmic particle horizon contained the mass of one typical galaxy); and interact very weakly with ordinary matter and electromagnetic radiation (the "dark" in CDM).  It is believed that approximately 84.54% of matter in the Universe is dark matter, with only a small fraction being the ordinary baryonic matter that composes stars, planets and living organisms. Pierre François Xavier de Ram (September 2, 1804, Leuven - May 14, 1865, Leuven), was a Belgian papal prelate, Canon and historian, best known for being the first rector of the new Catholic University of Mechlin (1834) and then of the new Catholic University of Leuven (1835). The Katholieke Universiteit Leuven Kulak (Catholic University of Leuven Campus Kortrijk), or Kulak is a university satellite campus in the city of Kortrijk (Courtrai) of the KU Leuven.  It is the only university in the Belgian province of West-Flanders.  Kulak stands for “Katholieke Universiteit Leuven "Afdeling" Kortrijk" (Catholic University of Leuven "Branch" Kortrijk).  Although the university buildings were upgraded from a mere branch or dependence to a real campus in the late 1990s, the designation of "Kulak" is still used.  The main reason for this is that it rolls off the tongue much easier than the new letter construction with its three consonants ending.  Located in the city of Kortrijk in Flanders, the Kulak is officially a Dutch-speaking institution. 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. Adolphe Gésché (25 October 1928 - 30 November 2003) was a Belgian Catholic priest and theologian.  He was professor of Dogmatic Theology at the Faculty of Theology of the Catholic University of Louvain and author of several works in the field of Theological studies. 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. The "Georges Lemaître" ATV, or Automated Transfer Vehicle 5 (ATV-5), was a European unmanned cargo resupply spacecraft, named after the Belgian astronomer Georges Lemaître.  The spacecraft was launched during the night of 29 July (23:44 GMT, 20:44 local time, 30 July 01:44 CEST), 2014, on a mission to supply the International Space Station (ISS) with propellant, water, air, and dry cargo.  It was the fifth and final ATV to be built and launched, following the "Albert Einstein", which launched on 5 June 2013.  "Georges Lemaître" was constructed in Turin, Italy, and Bremen, Germany.  Cargo loading was completed in Guiana Space Center on 23 July 2014. The Friedmann–Lemaître–Robertson–Walker (FLRW) metric is an exact solution of Einstein's field equations of general relativity; it describes a homogeneous, isotropic expanding or contracting universe that is path connected, but not necessarily simply connected.  The general form of the metric follows from the geometric properties of homogeneity and isotropy; Einstein's field equations are only needed to derive the scale factor of the universe as a function of time.  Depending on geographical or historical preferences, the set of the four scientists — Alexander Friedmann, Georges Lemaître, Howard P. Robertson and Arthur Geoffrey Walker are customarily grouped as Friedmann–Robertson–Walker (FRW) or Robertson–Walker (RW) or Friedmann–Lemaître (FL).  This model is sometimes called the "Standard Model" of modern cosmology, although such a description is also associated with the further developed Lambda-CDM model.  The FLRW model was developed independently by the named authors in the 1920s and 1930s. Fuzzy cold dark matter is a hypothetical form of cold dark matter proposed to solve the cuspy halo problem.  It would consist of extremely light scalar particles with masses on the order of formula_1 eV.  Fuzzy cold dark matter halos in dwarf galaxies would manifest wave behavior on astrophysical scales, and the cusps would be avoided through the Heisenberg uncertainty principle. 1565 Lemaître, provisional designation 1948 WA, is a highly eccentric Phocaea asteroid and sizable Mars-crosser from the inner regions of the asteroid belt, approximately 8 kilometers in diameter.  It was discovered on 25 November 1948, by Belgian astronomer Sylvain Arend at the Royal Observatory of Belgium in Uccle, Belgium.  It was named after cosmologist and priest Georges Lemaître.
