In this series I am joined by Astrophysicist and Healthcare Futurist Ben Locwin. In this podcast we consider the TOS episode Tomorrow is Yesterday as a starting point for the consideration of the science around black holes, white holes, and wormholes.

In this episode, USS Enterprise is thrown back in time to Earth during the 1960s by the effects of a high-gravity "black star". The Enterprise ends up in Earth's upper atmosphere and is picked up as a UFO on military radar. Spock and Chief Engineer Scott inform Kirk of a possible escape method by slingshotting around the Sun to break away and return to their time. The maneuver is risky, since even a small miscalculation could destroy the ship, or make them miss their own era. Kirk okays the maneuver, and time on board the Enterprise moves backwards. The Enterprise is then successfully returned to the 23rd century.
