# Nova - s27e03 - Time Travel

NOVA examines the feasibility of time travel. The program: challenges early theories that time travel might be possible using a black hole. describes how wormholes, predicted by Einstein's theories, might provide a shortcut through time and space. shows how modern jet travel and atomic clocks have been used to prove Einstein's theory of special relativity. presents the views of such scientists as Carl Sagan, Stephen Hawking, and Kip Thorne. examines the consequences of the grandfather paradox and shows how laws of physics might prevent time travelers from changing the past, thereby affecting the future. presents a controversial experiment that claims to have sent a signal faster than the speed of light. introduces reasoning that the laws of relativity prevent a time traveler using a wormhole time machine from going back to a time before the machine was built. concludes with scientists disagreeing about the feasibility of time travel. Interviewees include physicists Carl Sagan, Kip Thorne and Guenter Nimtz. The production code is 2613, but was not s26e13; it was the 3rd episode broadcast in season 27 (1999–2000). VHS digitized to DV AVI and transcoded to H.264 MP4 in 2020.
