Have you ever wondered what the foundations of our reality are based on? What if I told you that the world around us is governed by mysterious particles and invisible dimensions? Would you believe me? Nothing could be further from the truth... However, we do not know the nature of the forces and elements that shape our universe. It is true that the scientific advances of recent centuries have allowed us to understand in detail the events that unfold on a macroscopic scale. But when we venture to smaller scales, it is as if we entered a parallel reality whose functioning escapes us. In this world of the infinitely small, the laws of physics and relativity that we know no longer apply. Instead, we find strange, sometimes invisible particles that interact in such mysterious ways that we find it hard to believe that they actually work. Quantum physics, string theory, supersymmetry, the uncertainty principle... So much vocabulary that tries to describe the mechanisms of this invisible reality to make it easier to understand. 🔥 As a reminder, videos are posted on SUNDAYS at 6:00 p.m. ------------------------- 💥Journey to the Small Infinite: Every discovery inevitably raises its own set of questions... In their quest to probe the microscopic world, scientists have nevertheless been able to delve into the tiniest secrets of nature. Whereas a few decades ago we thought that atoms were the inseparable building blocks of matter, today we know that these elements are home to an incredible bestiary of particles. Quarks, gluons, Higgs bosons, neutrinos, photons... It's enough to make your head spin! To say that these elements are tiny is an understatement. To understand this, let's compare scales. Observations of the cosmos tell us that the diameter of the observable universe is about 93 billion light-years. This universe would include between 100 and 200 billion galaxies. In fact, our Milky Way is just a tiny drop of water in a cosmic ocean. From our perspective, however, its dimensions are enormous: almost 53,000 light-years. That is enough to accommodate between 200 and 400 billion stars, and probably more than 100 billion planets... Between these stars is our sun: almost 700,000 km in radius. That is about 109 times the diameter of the Earth. Our beautiful blue planet, gigantic to our eyes, is actually invisible to those of the cosmos. For if the solar system were a city twenty kilometers in diameter, the Earth would be little more than a grape. And yet, almost 8 billion human beings live on it. But, again, appearances are deceptive, since man is far from occupying all the available space on Earth. If we were to group together all the human beings currently alive, they would fit on an area equivalent to the city of Los Angeles... So, compared to a modestly sized terrestrial planet, man is a grain of sand. If this comparison of scales gives you a slight headache, wait for the next part. Because it is possible to go much further. Each human being, as microscopic as it is compared to the cosmos, is made up of about 30,000 trillion cells. And these tiny cells, observable only under a microscope, are in turn made up of 100,000 trillion atoms! This figure varies greatly from one cell to another, but it is still completely excessive. Wait, we can go even further... If you look at the nucleus of atoms, you will be surprised to discover that they are 99.9%... empty! In other words, theoretically matter is made of nothing! It may seem crazy, but hidden in this nothingness are tiny elements of the quantum world that give life to the reality we know. And although we are made of atoms, their deep nature seems even further away than the confines of the observable universe. So, the infinitely small hides many mysteries. So get ready to travel to the heart of matter! Together, we will try to unravel its secrets by literally looking deep inside ourselves... ------------------------- 🎬 Today's program: 00:00 - Introduction 06:30 - The macroscopic world 22:40 - Diving into the heart of atoms 37:41 - Subatomic particles 42:06 - Quarks 51:40 - Leptons 53:58 - Bosons 58:37 - The Standard Model 1:07:42 - The Higgs boson 1:12:46 - The mysteries of quantum physics 1:23:18 - String theory 1:29:22 - Supersymmetry 1:32:45 - Loop quantum theory Jodisea is an official channel affiliated to the network ©ORBINEA STUDIO
