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.

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.

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.

In the late 1960s, a series of anomalous, repeating radio sources began cropping up all over the Milky Way galaxy, and though initially speculated to be messages from aliens, we soon learned that they are Pulsars, a rapidly rotating neutron star emitting high volumes of radiation. In this video, we will revisit these extreme, dense objects, as the final gateway faced by matter before it collapses into a black hole. This is the insane science of neutron stars.

How did Earth get its moon? Why is Mercury so close to the sun? Why does Uranus orbit on its side? The answers to all of these questions are the many collisions that ravaged the early Solar System. Each of our neighbouring worlds bears scars which echo their violent past, from the many craters of the moon's battered surface, to the sideways rings of the planet Uranus. And in this video, we will examine a number of the most significant collisions, which each played a pivotal role in building up the Solar System as we know it today.

The Sun... both the giver of life, and destroyer of worlds. Host of the eight planets, and incubator of Earth with its light and heat. Yet in spite of its brilliance, the true nature of the sun's power remains shrouded in mystery, with scientists unable to explain many of the processes playing out in its atmosphere. But in 2024, NASA will attain their closest glimpse of the sun so far, as they come just five million miles from its surface, diving into the stellar Nether Zone, to "touch" the sun itself.BACKGROUND TRACK: "Christmas Ambience" by CO.AG MusicSong: https://youtu.be/e23_O1koRiA?si=5gebdLo6tpmIQpY3Artist: https://www.youtube.com/channel/UCcavSftXHgxLBWwLDm_bNvACHAPTERS:00:00: Welcome... 01:45: Anatomy of the Sun 05:03: The Coronal Mystery 08:21: Space Weather & the Solar Cycle11:59: Geomagnetic Storms15:31: The Carrington Event18:38: A Geomagnetic Storm in 2024?22:20: Missions to Study Space Weather 25:02: The Parker Solar Probe 30:28: Parker's 2024 Mission

It's been more than half a century since humans last went to the Moon. But we will return before the decade is up, through NASA's revolutionary Artemis Program. But unlike its ancestral Apollo Program, Project Artemis is about more than just landing astronauts on the lunar surface. Its endgame is to enable us to stay there, and keep going back to a semi-permanent surface habitat- all in preparation for NASA's yet more ambitious, daunting endeavour of the 2030s- to reach the Red Planet, Mars.

Of all the spacecraft to have visited other worlds, there are two which have travelled further than any other, discovering more about the Solar System than their inventors ever could have imagined. They are the legendary pair of Voyager Probes- still the only spacecraft ever to have visited the Ice Giant planets, Uranus and Neptune. The story of their 40 years in space makes up the topic of our video today- from the gas giants, to the ice worlds, and then out into the depths of interstellar space...SOUNDTRACK: - Just a Shadow | CO.AG Music (https://youtu.be/pRDzXIV5yKg?si=Z4ooBaD1wZmV_Y7B) - Deep Sleep | Amber Waldron (Storyblocks)- Beyond This Earth to the Stars | CO.AG Music(https://youtu.be/aPQl1d96_Bk?si=sLbl_gG8oqhcwuW0)- Contemplative | Amber Waldron (Storyblocks)- Spa Go | Gushito (Storyblocks) - Descend Into Horror 5 | CO.AG Music(https://youtu.be/Ev49l2ZGFmg?si=Cj4CUoob2wRCjSaQ)- Guitar Drone Meditation | Humans Win (Storyblocks)- SpaceShip | Jayson Wayne Brown (Storyblocks)CO.AG's Channel: https://www.youtube.com/@co.agmusicCHAPTERS00:00: Welcome Back01:31: The Grand Tour 06:00: Voyager-1's Gas Giants Mission09:40: Voyager-1's Titan Flyby12:27: The Pale Blue Dot14:30 Voyager-2's Gas Giant Mission18:15: Voyager-2's Uranus Encounter 21:24: Voyager-2's Neptune Encounter25:00: Exiting the Heliosphere 29:19: The Interstellar Mission 34:04: One Final World...

From studying the dusty surface of Mars, to plunging into the atmosphere of Venus, over the last 60 years, we've launched hundreds of probes into space on trajectories to visit each of the terrestrial planets. But for all the fascinating discoveries made on the way, humanity's journey towards the stars started out in a much darker place- a battlefront between the world's then two great competing superpowers. And in this first episode on my new series on probes, we will revisit this space race, and the major milestones on route to visiting each of the terrestrial planets.CHAPTERS:00:00: Introduction02:32: The Space Race 04:48: Pioneer Probes07:32: Mariner Probes09:55: Mariner 4 Mars Mission12:27: Mariner 6 & 714:27: Mars Orbiters17:05: Landing on Mars 18:57: Landing on Venus 21:30: The Viking Probes26:12: Mercury Missions33:00: Mars Rover Missions 38:16: To be Continued...

Earth is a success story, a thriving world that has hosted life for almost 4 billion years. But, no matter how peaceful things are now, a new age is coming for the Solar System. An age of change, destruction and evolution. A place for new worlds and new stories, but one in which the Earth has no place.MUSIC:- Dreamscape - Density & Time - The Unknown - CO.AG Music - https://youtu.be/IFYTGVE1aRs- Sunrise on Mars - Audionautix- As Prevent You Do - pATCHES - At the Foot of the Sphinx - Twin Musicom - It Maintains, Eyes Change - Puddle of Infinity - Growing Space - Astron - The Blue Pearl - Jesse Gallagher - Kallimachou - Dan Bodan Sunrise on Mars by Audionautix is licensed under a Creative Commons Attribution 4.0 license.https://creativecommons.org/licenses/by/4.0/Artist: http://audionautix.com/CHAPTERS: 00:00: Welcome Back00:15: The Next Billion Years 06:10: Milkdromeda Collision08:03: The Red Giant Branch13:12: Habitable Moons16:27: Titan 21:00: Titan's Prospects for Life23:24: Horizontal and Asymptotic Giant Branch26:52: The White Dwarf Sun29:19: The Solar System's Last Day
