It’s a rare day when you can rediscover the influencer words of world-famous thinker Albert Einstein himself.
Nearly 20 minute video interview with “Father of” big bangwas discovered in the archives of a public broadcaster called Vlaamse Radio-en Televisieomroeporganisatie (VRT) in the Flemish region of Belgium.
Scientist looking at lost footage To tell“Peeping into time” feeling.
The intelligent interview, conducted in French, was originally aired in 1964 and the footage was believed to have gone missing. Now it has finally been restored and is available online for anyone to watch, albeit with Flemish subtitles. arXiv.
George Lemaître was Belgian cosmologist and Catholic priest Who was the first to understand that the universe was expanding even before Edwin Hubble demonstrated the effect? with the world’s largest telescope.
Finally Lemaître’s logic Sure Einstein in the early 1930s admitted that he was wrong and that the universe cannot be static. general relativity.
According to Lemaître, the universe is An ancient “cosmic egg”the atom that exploded into A fireworks show of cosmic rays that continues to spread It continues to this day.

However, not everyone was convinced by Lemaître’s theory, and many of his interviews in 1964 were devoted to countering his challengers.
“A long time ago.” Lemaître I will explain In the video, “Before the theory of the expansion of the universe (about 40 years ago), we expected the universe to be static. We expected nothing to change.”
this is, steady state hypothesisan idea championed by British astronomers fred foil Opposes Lemaître’s ideas.
according to foilthe universe was like a “smooth flowing river”, dynamically creating new substances without constant change.
If this is true, then there should be a mixture of young and old galaxies throughout the universe if matter is continuously being produced and sent downstream.
The big bang (a term coined by Hoyle), on the other hand, means that old galaxies are far from the epicenter of the explosion.
These two scenarios were hotly debated for years, but it wasn’t until the 1950s that astronomical observations confirmed the latter situation to be true.
“As far as we go with theory, the first result of this decay is actually to have the universe, an expanding space filled with plasma, by very high-energy rays going in all directions,” says Lemaître. I will explain In a recently rediscovered interview.
“Something that doesn’t look like a homogeneous gas. Then by vaguely imaginable processes, unfortunately, it cannot be traced in so many details that the gas had to form locally. The gas cloud moves at high speed…”
Both Hoyle and Lemaître agreed that these gas clouds are composed almost entirely of hydrogen. However, the two scientists disagreed on how these hydrogen gases were generated.
Hoyle believed they were naturally generated through “rational physical processes”. I will explain Lemaître during an interview. Lemaître thought of its beginnings as “a sort of phantom hydrogen that appears with just the right amount of hydrogen to test the a priori law”.
Cosmic rays passing through space are essentially the first ghostly fossilized atoms.
“Of all the people who came up with the cosmological framework we are working with, few records document how they spoke about their work.” To tell Physicist Satya Gontcho A Gontcho, US Department of Energy, co-author of the preprint paper.
One of the most fascinating parts of the lost interview is when Lemaître is asked how he reconciles his scientific theories with his religion.
“I am not defending the primordial atom for any religious ulterior motive,” he said. To tell in an interview.
“Obviously a bit of a sensitive point,” he adds. “Now I’m a little scared to elaborate in a few words.”
An astronomer and priest, he did not believe that the Big Bang contradicted his religion, nor that science demanded a religious explanation. This topic was obviously not something he was interested in discussing openly.
“Lemaître and others have given us the mathematical framework upon which our current efforts to understand our universe are based.” To tell Goncho.
“Cosmology seeks to understand what happened in the past of the universe, and for most of us who make observations, it is a very precise measurement of the rate of acceleration of the universe at different moments in time. I mean, if expanded at different points, what can be narrowed down to dark energy can be “
