Dark energy is making the universe expand faster every second and no one knows what it is. The film traces Edwin Hubble's discovery of redshift and the expanding universe, why gravity should slow expansion like a ball thrown upward, and how dim Type Ia supernovae in 1998 proved it is accelerating instead.
