Program Overview
|
|
|
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.
