On s'est trompés sur le BIG BANG (James Webb relance TOUT)

A telescope is a time machine. Because light takes time to reach us, observing space is like looking into the past. The farther a telescope can see, the more it allows us to glimpse phenomena that occurred billions of years ago, at the very beginning of the universe. This is precisely what the James Webb Telescope allows, designed with extreme optimization to capture infrared light from the far reaches of the cosmos. Thanks to it, astronomers have been able to observe galaxies much older, more massive, and more structured than our models predicted. And these discoveries have profoundly changed our understanding of the universe, opening the door to new questions about its origins and evolution. ___________ 🖋 Written by: Christophe Pauly 🎞 Edited by: Margaux Charrière 🤝 Commercial collaboration: [email protected] My other accounts - ➡ Facebook:   / christophepauly.tv   ➡ Instagram:   / christophepauly.tv   ___________ Chapters: 00:00 A telescope is a time machine 02:21 Why James Webb can see the past 03:06 Hubble: revolutionary, but limited 04:26 Redshift: why the distant universe becomes infrared 05:10 Why we had to leave Earth 05:47 James Webb, the telescope designed for infrared 06:33 The engineering nightmare of the James Webb 08:15 The golden mirror, the L2 point, and the total risk 10:34 The most Risky in space history 11:13 The first image that changed everything 12:06 What the standard model of cosmology predicted 14:31 The impossible galaxies discovered by James Webb 17:43 Little Red Dots: the new cosmic mystery 20:59 The “naked black hole” that defies all theories 23:19 The oldest supernova ever observed 25:24 James Webb also looks at exoplanets 26:23 Are our models of the universe wrong? 28:27 When anomalies advance science 29:34 The universe is stranger than anything we imagined
