  • The Sounds of Space: A sonic adventure to other worlds


    A collaboration with the podcast Twenty Thousand Hertz:
    Soundtrack: | Space is more than just a feast for the eyes. It’s a feast for the ears. You just have to know where -- and when -- to look.

    Floating in the silent void of space are trillions of islands of sound, each with their own sonic flavor -- some eerily familiar, some wildly different than Earth’s. And even space itself was once brimming with sound.

    This short film takes you on a journey back in time and to the edge of our solar system and beyond, to discover what other worlds of sound are lurking beyond Earth's atmosphere. You won't believe your ears :)

  • The Cosmic Scale


    How large is the universe? Where does it begin and end? And how does it expand? These are some of the biggest questions of astronomy. And while humanity is so small that we may never be able to fully understand the true scale of the universe, advancements in technology are helping us to look ever-deeper into the wilds of our existence- towards the edge of our observable universe, known as the Cosmic Horizon. Today, we will analyse the universe, its laws, and its awe-inspiring scale.
