SEA: Space Exploration & Astronomy

What is the largest star, and where can it be found? For a few years now, it has been known as Stephenson 2-18, often claimed to boast a diameter more than 2,100 times our sun’s. But is this estimate really reliable? And if not, then what other giant stars may be lurking out there? These are the questions we will be aiming to answer as we wind back the clock in search of the real “largest star”. MUSIC: - Holographic Rain - CO.AG Music (https://www.youtube.com/watch?v=37aEn7yuChQ)- Strange Visions (Giuseppe Rizzo)- Endless Mist (Enzo Orefice)- Dystopia - Instrumental (Efliz) - Nights of Darkness 01 - CO.AG Music (https://www.youtube.com/watch?v=FwC9HZv7Zw0)- Static Balance (Enzo Orefice)- Agnus Dei (Michele Nobler)- Light the Way (Enzo Orefice)Artists: - Enzo Orefice: https://www.music-bay.net/artists/enzo-orefice/- CO.AG’s music channel: https://www.youtube.com/@co.agmusicCHAPTERS: 00:00: What is the Largest Star? 01:48: It’s Not Stephenson 2-18 05:20: Modern-day Contenders11:30: Primordial Stars15:47: Quasi-Stars 18:11: MoM BH*-1: Webb’s New Black Hole Star 22:28: A Source of Galactic Engines?26:20: The REAL “Largest Star” 

Far beyond the reaches of the four rocky planets, we find our Solar System's showpiece worlds- the two gas giants, Jupiter and Saturn. As the two largest planets, they both make tantalising targets for probes exploring the planetary neighbourhood, but both lie significantly further from the sun than the Earth and its terrestrial neighbours. But early in the 1970s, the technology for deep space voyages was primed, and missions to both Jupiter and Saturn ensued. Those missions make up the topic of our video today, in this second episode of our trilogy of Probes that Studied the Solar System.

In 2012, the world’s most advanced science experiment uncovered the signature of the Higgs Boson, the so-called “God Particle” which gives particles their masses. The Higgs was the last of the Standard Model's particles to be verified experimentally. But far from closing the case, it instead opened a new frontier in physics that today embodies everything we still don’t know about nature’s smallest scales. And so in this video, we will wind back the clock more than half a century, to unravel the history and mysteries of the elusive Higgs Boson.SOUNDTRACK:- “Adega” - CO.AG Music (https://www.youtube.com/watch?v=V2faIhMd5GY)- “Cold Constellations” - Enzo Orefice - “No Eyes in the Fog” - Enzo Orefice - “Creepy Dolls” - Efliz - “Vanished Minds” - CO.AG Music (https://www.youtube.com/watch?v=YPQM8Twz5ec)- “Orbiting Dreams” - Enzo Orefice - “Sunrise” - Enzo Orefice - “Parallel Dimensions” - Enzo Orefice - “Hidden Presence” - Enzo Orefice- “I Vanish When the Sun Awakens” - CO.AG Music (https://www.youtube.com/watch?v=T5fLFlAI0Fw)Artists: - Enzo Orefice: https://www.music-bay.net/artists/enzo-orefice/- CO.AG Music: https://www.youtube.com/@co.agmusic/videosCHAPTERS:00:00: The Standard Model 01:58: The Higgs Field 04:53: The Weak Force Problem 08:12: Early Particle Colliders 12:14: The Large Hadron Collider14:04: Detecting the Higgs Particle 18:31: Sigma Significance 20:23: Discovery in 201223:26: Naturalness vs. Fine Tuning27:01: Supersymmetry29:54: Future Colliders 32:05: Vacuum Decay

Why does the universe choose life over silence? Why has its once inanimate matter and energy come alive on planet Earth? Is it chance? Fate? Or even, by design? It is this profound question that has plagued our conscious minds since the time of our earliest ancestors, and it is going to be the topic of our video today. This video is my oldest idea, and I was planning for it as early as 2021. A massive thank you to the artist Semiquaver for composing the soundtrack that brought this vision to life. SOUNDTRACK:The soundtrack for this video was crafted by Semiquaver, an ambient music and soundscape artist who I'd been following for a while, and knew he was perfect for the job. His channel can be found here:  @semiquaver16th  , where he regularly releases new soundscapes and compositions. The full, 37 minute track will be available to listen to here: https://youtu.be/WQQhwggE6BoCHAPTERS:0:00: What Does It Mean? 1:55: Cosmic Fine-Tuning7:22: The Universe is Infinite10:45: Parallel Universes 14:47: Design Hypothesis 18:56: Cosmic Consciousness 22:02: Boltzmann Brain 25:03: We Are Alone28:30: Theory of Everything

Can we ever turn back the clock? On Earth, Time is rigid and immovable, but in space, it's practically the opposite. Out in the cosmos, time is another dimension alongside the three of space- but unlike in 3D space, there is only one way we seem to be able to move through time. The cause of this directionality, and so-called "Arrow of Time" through the cosmos, makes up the topic of our video today- the second part in a double header on the mysterious workings of Time.SOUNDTRACK: The first and last tracks in this video were composed by Semiquaver, an ambient soundscape music artist. He and I will be working on an original piece specially for the soundtrack to my final video of the year, so go and check him out before then: @semiquaver16th  The other tracks were composed by CO.AG Music, my go-to-guy for such high quality pieces:  @co.agmusic  "Why Me?" - Semiquaver: https://youtu.be/kfp-Qm99BTY?si=ZOUiOTxLgpkHgWhd"Space is as Clear as Dreaming" - CO.AG Music: https://youtu.be/FQ42GG9ReC4?si=ceWagFlaEY3qOiuH"You Can Escape Everything in This Life Except Yourself" - CO.AG Music: https://youtu.be/O58i-jHGYVs?si=mSBKH-WITwGaLV1z"Old Tape Haunting Soundscape" - CO.AG Music: https://youtu.be/LT_APDKFEjU?si=M7h8OTIyC5QtV0Px"I Will Awaken When the Sun Sleeps" - CO.AG Music: https://youtu.be/IshEmQXBi7g?si=mzCVDnGXV28K0TzpCHAPTERS00:00: Welcome Back...01:56: The Fourth Dimension 06:28: Time Dilation11:15: Forward Time Travel 12:42: General Relativity15:00 Backwards Time Travel 18:38: The Second Law21:49: Reverse Entropy23:48: Out of Time
