    The History of Time

    Tick. Tock. It's a sound you probably hear several times a day. Time dominates virtually every aspect of our lives, attuned to the rigid, unflinching regularity of Hours, Minutes and Seconds. The question how did our ancient ancestors figure out these units? Who came up with the concepts of timekeeping, like Minutes and Seconds, and why are there 60 of them, and not say, 100? The answers to such questions make up the topic of our video today- the first in a two-part series on the mysterious workings of Time. Tick. Tock. It's a sound you probably hear several times a day.

    Leviathans: Giant Creatures of the Deep Sea

    Aliens. They already roam this planet, but not on its surface or in the skies. Rather, they lie at the crushing depths of the vast, sprawling oceans. And so in this episode, we'll be swapping the familiar frontier of space for that of the deep ocean, as we plunge into the abyss in search of Leviathans- massive, monstrous marine specimens that have stalked the high seas for almost half a billion years.

    Antarctica: The Alien Continent

    On the dark, secluded underside of our planet, we find its most alien continent, Antarctica. A frozen desert larger than Europe, lying atop a sheet containing more than 90% of the world’s ice. But buried beneath this frosty surface, lie fossils and relics from an age where Antarctica was wildly different- covered not by ice, but by forests of trees.

    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.

    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.
