SEA: Space Exploration & Astronomy

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.

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 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.
