L'Univers avant le Big Bang

Il y a moins de dix ans, une telle question aurait eu des allures de sacrilège. Pour les cosmologistes, une telle interrogation n’avait tout simplement pas de sens. Imaginer une époque antérieure au Big Bang, c’était comme chercher un point au Nord du pôle Nord. Selon la théorie de la relativité générale, un Univers en expansion doit avoir commencé par un Big Bang, ce qui implique la finitude du temps, apparu simultanément avec l’espace et l’énergie-matière. Cette façon de voir s’est modifiée au cours des dernières années. This is the Most Detailed Map of the Universe to Date.

The surprising finding, based on 3D modeling of images collected over 20 years by the Hubble Space Telescope, was published in the Astronomical Journal.

Physicists Believe They've Discovered a Fifth Fundamental Force of the Universe. Although physics may seem complicated to the uninitiated (or even to the trained professional, for that matter), it’s worth remembering that physics deals with only four known forces: gravity (which keeps us from floating off the Earth); electromagnetism (which binds electrons to atoms, and atoms to each other); and two forces that operate over very short distances—the strong nuclear force (which binds atomic nuclei together) and the weak nuclear force (which governs certain kinds of radioactive decay).

Physicists Believe They've Discovered a Fifth Fundamental Force of the Universe

But if recent experimental work in particle physics pans out, we may have to get used to the idea of a fifth force. The research outlining the evidence for this fifth force was published last week in the journal Physical Review Letters. If the discovery holds up, it will radically shake up what we know about the workings of the universe. The Edge Of The Universe Is Closer Than Scientists Previously Thought. The visible universe just shrunk by 320 million light-years in all directions, updating a famous calculation that physicists first made 13 years ago. If you're trying to calculate the size of the cosmos, the speed of light — the fastest anything can go — is a tempting place to begin and end. You'd reason that since the Big Bang happened some 13.8 billion years ago, there's a 13.8-billion-light-year radius marking the edge of what mere mortals could see.

Not so. As physicists have shown again and again over the past century, space is expanding faster and faster. There's also a blinding glow of light that didn't clear up until about 378,000 years after the Big Bang — an event called recombination (when particles finally cooled down enough to form the first atoms). If you take expansion, recombination, and other variables into account, as physicist J. A Guide to Different Kinds of Parallel Universes « NOVA's Physics Blog: The Nature of Reality. These days it often seems that if a theory has loose ends, its dangling threads are surreptitiously tied together out of view within the hidden fabric of a parallel universe. While some researchers recoil from introducing unseen aspects to a theory, others find that the invisible knots create an irresistibly pretty package.

Depending on one’s taste, there are so many types of parallel universes to choose from—alternative cosmos galore. New quantum mechanics theory says parallel universes exist, interact.

L'Univers pourrait avoir un "bouton de suppression", remettant en cause la physique telle que nous la connaissons. Des physiciens ont suggéré le fait que l’Univers pourrait avoir un mécanisme « d’autodestruction », de sorte que tout ce qui existe pourrait disparaître à jamais et à tout moment, sans aucun élément précurseur. Un sujet portant à réflexion. Comme nous pouvons le voir dans la vidéo proposée par Kurzgesagt – In a Nutshell (vidéo en anglais, lien en fin d’article) : si ce bouton d’autodestruction se révèle être réel, cela signifie que nous pourrions être totalement réduits à néant, en moins d’une seconde.

Our galactic neighbor Andromeda almost certainly expired a few billion years ago, but only recently started showing outward signs of its demise. Galaxies seem to be able to “perish” – that is, stop turning gas into new stars – via two very different pathways, driven by very different processes. Galaxies like the Milky Way and Andromeda do so very, very slowly over billions of years. Multiverse. Multiverse. Multiverse. Quantum physics.

Quantique. Quelques éléments de physique et de philosophie des multivers. Quelques éléments de physique et de philosophie des multiversPar Aurélien BarrauEssai publié en libre-accès 130 pages Présentation par Jean-Paul Baquiast 06/10/2007 The « Flat-Earth Wood-Cut » 1) Nous avons découvert Aurélien Barrau à l’occasion de son entretien avec Stéphane Deligeorges, sur France Culture, Continent Sciences, le 24 octobre 2007. Dans cet entretien, en grande partie consacré à l’hypothèse des multivers ou plurivers, il présentait une démarche remarquable, entre science et philosophie. Par cette démarche, pour reprendre une de ses expressions, il » essaie de créer une porosité entre l’espace scientifique et le monde mythique, de penser la plurivocité intrinsèque du réel, sans pour autant rien renier de la rigueur physico-mathématique et sans recourir aux métaphores élégantes mais inexactes ».

Il nous avoue ne pas savoir s’il y parvient. Le thème essentiel qui inspire l’auteur, thème présenté dès l’introduction du mémoire, est celui du «retour de la contingence».
