Documentary on time travel, paradoxes, special relativity, quantum mechanics, frame dragging,
and more—told largely through interviews with modern physicists with a backdrop of a corny
Museum of Time Travel in the future. Good explanation of relativistic time dilation using
Einstein’s twin brother Bertrand and a light clock. Fun interview with physicist David
Deutsch about the quantum multiverse and its relation to time travel paradoxes. Fun
discussion of
the first Superman movie. Jaw-dropping first-hand explanation
from physicist Ron Mallet of how light might twist spacetime and result in particles being
sent to the past. Attractive fashions worn in the museum of the future.
— Michael Main
David Deutsch: If Ron Mallet’s experiments turn out has he
hopes, then it would immediately put an end to the controversy about whether time travel
would ever be practicable.
