    Before Pangea: The Supercontinents

    Long ago, the Earth's seven continents were assembled in a giant, sprawling supercontinent known as Pangea. You may've heard of it, but what is often less talked about is what came before. Our planet's current continental chunks have been smashing together and separating for over four billion years, and there have been more than a few "supercontinents" during that time. It is those lost lands that take the stage in this video, as we wind the clock back to the age of the Supercontinents before Pangea.

    You Are Here

    As rich and life-supporting as the Earth is today, it was once nothing more than a column of dust, dancing in a scorched cyclone of gas. And just how we as humans managed to emerge from this ancient dust makes up the topic of this video today. So join us, as we wind the cosmic clock backwards almost five billion years, from you and I in the present, all the way back to the birth of the solar System, back to when Earth was nothing more than a burning, barren wasteland.

    You Live in a Supervoid

    Do we live in a cosmic void? It might sound like an odd question, but it’s something scientists have debated for decades. Does the Milky Way exist in a region of low cosmic density which is warping our view of the local universe as a result? The answer goes far deeper than you probably realise- and it’s just one of the many perplexing mysteries we’ll be diving into during this video, where voids and supervoids take centre stage. SOUNDTRACK: The music tracks in this video were composed by Enzo Orefice, a royalty-free music creator. In order of appearance they are: - “Psyconaut” - “Submerged In Silence” - “Borealis Glow” - “Timeless Flow” - “Void Waves” - “Stellar Winds” Artist: https://www.music-bay.net/artists/enzo-orefice/ CHAPTERS: 00:00: You Live in a Supervoid 05:55: The Local Void 09:22: Boötes Void 12:06: The Dipole Repeller 15:54: The Mystery of the Cold Spot 23:12: Evolving Dark Energy 28:51: Future Efforts to Study Voids

    Engine Black Holes: The Most Massive Objects in the Universe

    Lying at the cores of most large galaxies, do we find the “largest” type of object in the universe- a supermassive “engine” black hole. They almost always have masses many millions of times that of the sun, while the biggest grow to tens of billions. Exactly what was responsible for seeding these great engines, and building up their immense sizes, is a challenge only the James Webb Telescope can rise to. MUSIC: The majority of tracks in this video are royalty-free tracks from Storyblocks. Exceptions are listed. - The Second One | Enzo Orefice - Falling | Elfiz - Haunting Atmospheric Si-Fi Sounds… | Gerardo Garcia Jr - Meditation Vibes | Sleeping Ghost - Voice | Elfiz - Incarnation | Scott Buckley Scott Buckley’s track can be found on his website: https://www.scottbuckley.com.au/2024/10/new-library-track-incantation/ CHAPTERS: 00:00: The Most Massive Objects 01:48: The Cosmic Dawn 05:33: Primordial Black Holes 07:02: Direct Collapse 09:07: Distant Supermassive Black Holes 13:35: Webb Telescope’s Findings 16:34: The Biggest Black Holes 21:31: The Distant Future 23:12: The End of the Universe 25:13: Hawking Radiation 28:22: Exploding Black Holes!

    Lost Worlds in the Dark

    Laced within the cold, desolate swathes of the space between stars, lie myriad orphaned planets not tethered to a particular system. They are lost worlds floating in the dark, and there are likely tens of billions in the Milky Way galaxy alone. Today, we will journey through the galaxy in search of these lost worlds in the darkness of interstellar space, and sometimes even, intergalactic space.

    The Fundamental Forces of Nature

    The universe as we experience it is rendered by myriad physical processes and interactions, but they all can be boiled down to one of four fundamental forces of nature. Gravity is one of these fundamental interactions, while the visible light we observe makes up part of another. And by understanding all four, we can gage comprehensive insights into our reality, from its tiniest particles to its largest galaxies.

    The Sound of Space

    What is the Sound of Space? The idea that it is a silent vacuum, completely devoid of any noise, is somewhat a misconception. And though sound as humans hear it can't travel in space, there are several way in which we can extract the anthems of the cosmos. And in this video, we'll be doing just that, as we embark on a journey of Sound in Space. SOUNDTRACK: - Uranus Sounds: https://youtu.be/yXfJG1gs3b4?si=zbgOABUBuLOtufgO - The Neptune Sounds: https://youtu.be/rwnpXll_A_E?si=sxZqKfccykjGixWZ - Jupiter Sounds (So Strange): https://youtu.be/e3fqE01YYWs?si=hIYAcZF1U7mRMMpY - Saturn: https://youtu.be/eVfkW9oxhIk?si=1w8tIgRNir342LvF - "Carpe Diem" - CO.AG Music: https://youtu.be/iuMBV3j55-I?si=gGwaRE5Hsgxm40rU - "Scrooge Ice Mix" - CO.AG Music: https://youtu.be/C9jFL_6raL8?si=kKR-3t6i46kGJF7d CO.AG's Channel: https://www.youtube.com/@co.agmusic - "Does it Exist or Do I Have to Create It" - Chris Zabriskie (Creative Commons Licence 4.0) Link: https://chriszabriskie.bandcamp.com/track/does-it-exist-or-do-i-have-to-create-it Artist: https://www.chriszabriskie.com/ CHAPTERS: 00:00: A Journey of Sound 01:17: Sound in Science 06:14: Whistler-Mode Waves 08:51: Sound of the Sun 11:25: Sounds from Terrestrial Planets 14:38: Sounds from Giant Worlds 17:48: Voyager Sounds from Deep Space 19:36: Pulsars 21:54: Gravity Waves 25:06: Sonifications of Visual Data 31:52: The True "Sound" of the Universe

    Do We Live in a Multiverse?

    Are we living in a multiverse? If so, where are all the other universes? Scientists and philosophers have pondered these questions for centuries, as they contemplated the possibility of parallel universes. The multiverse theory is not often discussed by cosmologists, due to its speculative and untestable nature. However, there are myriad different interpretations depicting how a multiverse might manifest, some of which we may be detectable within our own universe. So buckle up, because in this video we will be leaving the galaxy entirely, as we take on the biggest question of them all- the question of whether our universe is the only one.
