The Largest Black Hole in the Universe - A comparison by size

The Largest Black Hole in the Universe - A comparison by size Black holes are some of the most mysterious and fascinating objects in the universe. But just how big can they get? In this video, we explore the largest black holes ever discovered, including Phoenix A, TON-618, and the ultramassive black hole in IC 1101. We compare their sizes to our Solar System, stars, and even other supermassive black holes (SMBH) found in galaxy clusters like Abell 2029, Abell 1201, and Abell 85. 🕳️ What You'll Learn: ✅ What is the largest black hole in the universe? ✅ How does the event horizon of a black hole compare in size? ✅ What is a relativistic jet, and why do black holes produce them? ✅ How did Phoenix A in the Phoenix Cluster* grow to 100 billion solar masses? ✅ The role of AGN (Active Galactic Nuclei), quasar activity, and radio galaxies like 4C+74.13. 🌌 Featuring Insights from NASA & Scientific Research We explore data and conceptual image lab visualizations from NASA’s Goddard Space Flight Center, featuring experts like Scott Wiessinger. Learn about the accretion disk, plasma jets, and the cooling gas that feeds these titanic objects. We also examine theories on black hole mergers and stellar black holes, and how they grow into intermediate-mass and supermassive black holes. 📌 How Did Phoenix A Black Hole Get So Big? We dive into this question using real astrophysics research, discussing star formation, galaxy collisions, and the BCG (Brightest Cluster Galaxy) phenomenon. 🔭 If you love astronomy, science, and space documentaries, this video is for you! We compare the biggest black holes ever discovered to everyday cosmic objects, putting their scale into perspective. 🔔 Subscribe to @cosmoknowledge for more mind-blowing space content! *Timeline:* 0:00 - Introduction 1:30 - What is a Black Hole? 3:00 - Scale of Black Holes 5:00 - Phoenix A* Overview 7:30 - Accretion Disks Explained 10:00 - Size Comparison with Other Black Holes 12:00 - Fun Facts about Black Holes 14:00 - Conclusion & Audience Interaction OUTLINE: 00:00:00 Unveiling the Enigmatic Black Holes 00:01:47 Journey to the Heart of Darkness 00:03:30 The Birth of Black Holes 00:05:02 Bridging the Gap 00:06:19 Guardians of the Galactic Center 00:07:49 Lords of Gravity and Light 00:09:41 The Black Hole's Glowing Halo 00:11:27 A Cosmic Giant Awakens 00:13:32 Comparing Black Hole Heavyweights 00:15:06 A Distant Quasar's Colossal Heart 00:16:48 A Galactic Giant
