Speed's the key to unlocking the mysteries of space, yet the faster we go,

the stranger and more exotic

the universe becomes.


In the vast expanse of space, nothing matters more than speed. Whether we’re venturing out to the farthest reaches of our solar system or exploring the mysteries of time travel and wormholes, speed is the key.

With riveting footage, Known Universe: The Fastest explores interstellar travel, wormholes and black holes and re-examines Einstein’s theories which might hint at the existence of portals that could reach through the very fabric of space and time.
