Who has never dreamed of hearing and seeing videos of the great names in science from the beginning of the 20th century, such as Einstein, Heisenberg, Landau, Gödel, etc.? ? Miraculously, we have just found images and a soundtrack in excellent condition showing Georges Lemaître, the discoverer with Georges Gamow of the Big Bang theory, a theory which is now part of the heritage of the noosphere with the theory of heliocentrism.
It's a stunning discovery that was recently announced in an online article by VRT NWS , the Belgian news and current affairs editorial office in Dutch, Flanders. We learn that an interview filmed in 1964 and which had been lost due to a referencing error in the archives was recently found. The interview is important since it shows for almost 20 minutes nothing less thanGeorges Lemaitre, the famous catholic canon,astronomerandphysicistBelgian originator of the Big Bang theory , which he called the theory of the primitive atom .
It was later developed byGeorge Gamow, Robert Herman and Ralph Alpher using thephysicalnuclear power born after the Second World War and which had allowed them to propose a scenario ofnucleosynthesisparamount for all the elements and which anticipated the discovery of the existence of thecosmic radiation.
But its acceptance did not begin to register, within the scientific community, until the discovery of fossil radiation in 1965 precisely. Before, we preferred the so-called stationary state theory. In retrospect, Lemaître's work is now seen as a precursor to thestandard cosmological modeland even attempts to use a quantum theory of gravity to overcome it.
As Futura has often reminded, theastrophysicistand French cosmologist Jean-Pierre Luminet had long defended, notably through publications available on arXiv , the pre-eminence of Georges Lemaître with regard to the foundation of modern cosmology.

JEAN- PIERRE LUMINETThe Big Bang against stationary cosmology
The theory ofBig Bangis a definitive achievement of the beginning of the 21st century . But it is so if by Big Bang theory we mean the theory which says that theUniverseobservable, which does not mean all that exists, was in a much more dense and hot state, without atoms orstars, say between 10 and 20 billion years ago. It could therefore be that our observable Universe is only a region of acosmosinfinite in space and in time which one day collapsed gravitationally, like a star giving ablack hole, before bouncing back into an expansion phase after reaching a limiting but finite density.
Legend has it that it was Fred Hoyle, shortly after the Second World War and at that time arguably Britain's finest cosmological theorist before the advent ofStephen Hawking, which was the origin of the term Big Bang, which can be translated as "The Great Explosion". Hoyle didn't believe it at all and, as Lemaître explains in the found interview, had very cordially debated his opposition to the Big Bang theory with Lemaître. The majority of cosmologists sided with Hoyle who in 1948, together with Hermann Bondi and Thomas Gold, had proposed the now defunct stationary cosmological model , a model denying the Big Bang theory of Lemaître and Georges Gamow.

2022 ST JOHN'S COLLEGE CAMBRIDGEIn the Hoyle, Bondi and Gold model, the cosmos was infinite in time and space, although paradoxically expanding. It was therefore absolutely homogeneous in space and time since no matter the place or the time at which an observer made measurements about it, he would always see the same things on average, without an evolution of thegalaxiesor thematterbe really noticeable.
But for that, Hoyle had to assume that a continual creation of matter must occur , leading to the equally continual birth of galaxies. Without this assumption, the cosmos would become more and more diluted with expansion.
As Lemaître also recalled, Hoyle was highly respected due in particular to his masterful contribution - with the American astrophysicist of British origin Margaret Burbidge and her husband Geoffrey Burbidge, and the Nobel Prize in Physics William Fowler - has an important article published in 1957 and which exposed nothing less than the recipe followed by the Universe to manufacture thechemical elementsin the stars. The paper has become famous to nuclear astrophysicists ever since as B 2 FH , after the initials of its authors. He showed that it was easier and above all more correct to explain the existence of heavy elements such asoxygen, thecarbon, I'nitrogenand theferwith the stars and not with the Big Bang.

However, a first nail in the coffin of stationary cosmology had been driven at the very beginning of the 1960s with the discovery ofquasars. It quickly became clear that it wasactive galactic nucleiall located several billionlight yearsat least theMilky Way, which therefore indicated that in the past the observable cosmos did not resemble that which was seen in thetelescopesa few million or hundreds of millions of light-years away. It was therefore a contradiction with the perfect cosmological principle at the base of the stationary model which implied that the cosmos precisely should not have looked different in the past.
Georges Lemaître will live long enough, until 1966, to witness the discovery of fossil radiation in 1965. Its characteristic ofblack bodyalmost perfect absolutely cannot be understood without the Big Bang theory of Lemaître and Gamow.
For those who would like to know more about Lemaître and the intellectual trajectory that will take him from reading Poincaré's famous treatise on cosmogonic hypotheses to studying general relativity with Arthur Eddington , the video below we owe Dominique Lambert is rich in information.
