Through the Wormhole (2010)

Episode Overview

What truly composes the universe? If you said stars, planets, gas, and dust, you would be mistaken. Three decades ago, researchers first identified a mysterious dark substance influencing galaxy movement. Currently, scientists estimate that dark matter exists in quantities five times greater than ordinary matter.

Additionally, there’s another enigmatic force at play—Dark Energy—which appears to be accelerating the expansion of the universe itself.
