		Loys de Cheseaux supposait que l’espace étoilé est infini.
		Le texte de Loys de Cheseaux passa malheureusement inaperçu, ou presque, et le paradoxe du ciel nocturne fut reformulé en 1823 par Olbers, un astronome allemand, et c’est généralement sous le nom d’Olbers qu’il est connu.
		A la fin de cette période, l’Univers s’est nettement refroidi, sa température n’étant que de 3000 K et il y eut un brusque passage de la matière de l’état ionisé à l’état neutre, ce qui marque le début de la quatrième phase.

	H. Grattan Guinness: Preacher, Teacher and Astronomer, by J. L. Haynes
		De Cheseaux is famous for his discovery of two comets, one a six-tailed comet, in the years 1744 and 1746 (“Philippe Loys de Cheseaux”).
		De Cheseaux writes, “I had no sooner discovered this cycle, than I observed that it was a quarter of the 1260 years of Daniel, and the Apocalypse, and that consequently, this period is itself a soli-lunar cycle…”(Approaching, 398).
		When de Cheseaux realized this, and that the 1260 year period was both an “appointed season” for earthly political events prophesied in Scripture, and an accurate soli-lunar cycle, he wondered if the 2300 years of Daniel 8, might also be a soli-lunar cycle.

	Jean-Dominique Maraldi (1709-88)
		Giovanni Domenico (or in French: Jean-Dominique) Maraldi (sometimes referred to as Maraldi II) was born on April 17, 1709 in Perinaldo, Italy, and was a nephew of Giacomo Filippo (Jacques Philippe) Maraldi (Maraldi I), who was in turn a nephew of G.D. Cassini.

		At Paris he was employed to do some geodesic measurements by using eclipse times of Jupiter's moons to determine longitudes, and obtained a longitude difference between Greenwich and Paris of 9m 23s (modern value: 9m 20.93s).

	BBC - h2g2 - Olbers' Paradox
		It was subsequently taken up by Jean Philippe Leys de Cheseaux of Lausanne, who thought that all of the sky should be as bright as the Sun.
		Olbers realised that actually the light reaching us should be infinitely bright, rather than as bright as the sun as de Cheseaux had proposed.
		de Chesaux and Lord Kelvin (who gave his name to the temperature scale) suggested that there might be dust in between us and many of the stars, blocking out the light that we receive from them.

	Olbers's paradox
		Olbers' paradox, described by the German astronomer Heinrich Wilhelm Olbers in 1823 and earlier by Johannes Kepler in 1610 and Halley and Cheseaux in the 18th century, is the paradoxical statement that in a static infinite universe the night sky should be bright.

	Philippe Loys de Chéseaux (1718-51)
		In 1745 and 1746, De Chéseaux compiled a list of 21 nebulous objects, of which he had originally discovered 8 objects: IC 4665, NGC 6633, M16, M25, M35 (this one might have seen before by John Bevis in England), M71, M4, and M17.
		De Chéseaux describes this comet in depth, which became brighter than Jupiter and at one time exhibited no less than six tails.
		De Chéseaux did not grow very old; he died on November 30, 1751 at age of only 33.

	Year Day Principle - Historicist.com The Protestant Interpretation of Biblical Prophecy. The Historical Alternative
		The background was this: Nearly a century before, a Swiss astronomer M. Jean Philippe Loys de Chéseaux—correspondent of the Royal Academy of Sciences of Paris, foreign associate of the Academy at Göttingen, and author of various astronomical and mathematical works and tables—had been engaged in chronological research.
		de Chéseaux had been pondering a possible relationship between the prophetic periods of the 1260 and 2300 years, as the duration of certain predicted epochs, and the facts of astronomy—that is, the cyclical periods measuring the planetary revolutions in the heavens.
		When de Chéseaux discovered the astronomical nature of this period, he regarded it as unmistakable proof of the inspiration of the book of Daniel.

	Messier Object 17
		The discovery of M17 by De Chéseaux didn't get widely known, so Charles Messier independently rediscovered it and cataloged it on June 3, 1764.
		The Omega Nebula M17, also called the Swan Nebula, the Horseshoe Nebula, or (especially on the southern hemisphere) the Lobster Nebula, is a region of star formation and shines by excited emission, caused by the higher energy radiation of young stars.
		As for many diffuse nebulae, the overall brightness of this object is difficult to estimate, and is given discordantly in the sources.

	Messier Object 16
		Cluster M16 (NGC 6611) discovered by Philippe Loys de Cheseaux in 1745-6.
		While De Cheseaux, in 1745-6, only discovered the cluster, Charles Messier, on his independent rediscovery of June 3, 1764 mentions that these stars appeared "enmeshed in a faint glow", probably suggestions of the nebula.
		Götz states that this is one of the intrinsically most luminous open clusters, at an absolute magnitude of -8.21.

	Messier Object 35
		The discovery of M35 is usually assigned to Philippe Loys de Chéseaux who observed and cataloged it in 1745 or 1746.
		It is also printed in John Bevis' Uranographia Britannica which was completed in 1750, so that this astronomer must have discovered it independently before this time, maybe or maybe not before De Chéseaux.
		Its hottest main sequence star is given as of spectral class B3 (Sky Catalogue 2000.0), and its Trumpler classification as III,3,r by all sources.

	Cosmological models
		This point was rediscussed by the astronomers Edmond Halley and Jean-Philippe-Loys de Chéseaux of Switzerland in the 18th century, but it was not popularized as a paradox until Heinrich Wilhelm Olbers of Germany took up the problem in the 19th century.
		It was also in 1917 that the Dutch astronomer Willem de Sitter recognized that he could obtain a static cosmological model differing from Einstein's simply by removing all matter.
		Ironically, recent theoretical developments in particle physics suggest that in the early universe there may very well have been a nonzero value to the cosmological constant and that this value may be intimately connected with precisely the nature of the vacuum state (see below).

	Strange Bedfellows: Edgar Allan Poe and Olbers' Paradox
		Over two centuries later, Swiss prodigy Jean-Philippe-Loys de Chéseaux proposed either stars were not evenly distributed in space, or something blocked their light from reaching us.
		Physician Heinrich Olbers published the problem in 1823, suggesting the something blocking star light was clouds of interstellar gas and dust, termed “nebulae” by Pierre-Simon de Laplace.
		In 1610 Johannes Kepler thought the dark sky meant the universe was not infinite; gaps between stars representing the edge of nothingness surrounding the universe.

	Olber's Paradox
		So de Cheseaux thought the sky would be as bright as the sun, whereas Olbers argued that it would be even brighter, and yet as everyone knows the sky is dark at night.
		If the number of stars is infinite, a stellar disk should cover every patch of sky." De Cheseaux claimed that a slight loss of light would solve the problem.
		1932 - Einstein abandoned the static universe models and with de Sitter developed a model that described an expanding universe in which the spatial geometry is flat, that is, the geometry obeyed the laws of Euclid.

	Untitled
		In 1750, the Swiss astronomer Jean-Philippe de Cheseaux, after thorough consideration of the distribution and brightness of stars visible in his observatory telescope, developed the geometrical argument stated above, that the decreasing luminosity of stars with distance should be exactly compensated by their increasing numbers.
		In 1974, Dirac debated the relative merits of "multiplicative creation" with matter entering the Universe where it is already most concentrated as Jeans and McRea would have it, and "additive creation" that would satisfy Stothers' model of matter appearing in the most tenuous space.
		Although de Sitter's solution of Einstein's field equations correctly predicted universal recession in accord with Hubble's empiricism, it was not taken seriously because it yielded an empty null cosmos, but this rejection was wrong because the mass-energy sum of the cosmos was, is, and always will be zero, born together and expiring together.
