In a new clip from the upcoming movie “UFO,” releasing digitally and on DVD Sept. 4, a mathematician played by Gillian Anderson discusses how aliens could use physical constants to navigate across space.
Along with Anderson (known for "The X Files"), the film stars Alex Sharp as a college student investigating UFO sightings near U.S. airports with his girlfriend (played by Ella Purnell), as an FBI agent (played by David Strathairn) pursues them. The film's science advisor was Space.com columnist Paul Sutter.
The clip, embedded above, discusses a novel idea for space travel: If a fundamental constant of the universe called the fine structure constant was different in different locations, beings could use the changing constant to navigate through space.
The fine structure constant relates to the strength of the electromagnetic force between elementary particles. Research has at times suggested that this constant might vary across the universe — so space travelers could use it to triangulate their location, Anderson's character says in the clip. That process could work similarly to how pulsar navigation would work, she adds. In that method, navigators would observe the regularly pulsing neutron stars to figure out their own locations. (A pulsar navigation experiment was recently tested on the International Space Station.)
While we're not sure exactly how navigation by fundamental constant fits in to the movie's suspenseful UFO-spotting premise, we're eager to find out.
