  2. History of Solar System formation and evolution hypotheses

    en.wikipedia.org/wiki/History_of_Solar_System...

    French philosopher and mathematician René Descartes was the first to propose a model for the origin of the Solar System in his book The World, written from 1629 to 1633.. In his view, the universe was filled with vortices of swirling particles, and both the Sun and planets had condensed from a large vortex that had contracted, which he thought could explain the circular motion of the plane

    The cosmic inflation hypothesis suggests that the shape of the universe may be unmeasurable. Since 2003, Jean-Pierre Luminet, et al., and other groups have suggested that the shape of the universe may be the Poincaré dodecahedral space. Is the shape unmeasurable, the Poincaré space, or another 3-manifold? Cosmic inflation:

    en.wikipedia.org/wiki/Cosmogony

    The Big Bang theory, which explains the Evolution of the Universe from a hot and dense state, is widely accepted by physicists.. In astronomy, cosmogony is the study of the origin of particular astrophysical objects or systems, and is most commonly used in reference to the origin of the universe, the Solar System, or the Earth–Moon system.

    The Big Bounce hypothesis is a cosmological model for the origin of the known universe.It was originally suggested as a phase of the cyclic model or oscillatory universe interpretation of the Big Bang, where the first cosmological event was the result of the collapse of a previous universe.

    [6] In the acknowledgments of the first edition of A Brief History of Time, Stephen Hawking writes that prior to his book "There were already a considerable number of books about the early universe and black holes, ranging from the very good, such as Steven Weinberg's book, The First Three Minutes, to the very bad, which I will not identify."

    More precisely, the Hartle-Hawking state is a hypothetical vector in the Hilbert space of a theory of quantum gravity that describes the wave function of the universe.. It is a functional of the metric tensor defined at a (D − 1)-dimensional compact surface, the universe, where D is the spacetime dimension.

    Laura Mersini-Houghton (née Mersini) is an Albanian-American cosmologist and theoretical physicist, and professor at the University of North Carolina at Chapel Hill.She is a proponent of the multiverse hypothesis and the author of a theory for the origin of the universe that holds that our universe is one of many selected by quantum gravitational dynamics of matter and energy.

    In his 1952 book The Creation of the Universe, Gamow explained Hans Bethe's association with the theory thus: [2] The αβγ paper with the figure referred to in the text. The results of these calculations were first announced in a letter to The Physical Review, April 1, 1948. This was signed Alpher, Bethe, and Gamow, and is often referred to ...
