Beyond the Cosmic Horizon

Please Note: This is a very old video of mine. Watch the newer, updated HD version of this video: The Cosmic Scale

In 2012, scientists detected the most distant galaxy discovered to date. This galaxy is now expected to be over 46 billion light years from the Earth, at the very edge of the observable universe. But what differentiates the observable universe and the rest of the universe? Today, we examine how a 13 billion year-old universe can be hundreds of billions of light years in diameter, and what might be waiting for us behind the barrier of the cosmic horizon.
