Factual error: In the scenes where Gardner is messaging his Earth based female friend Tulsa from his Mars home, their communication is shown as being in real time. In truth, there would be minimum of a 4 min lag between messages due to the distance. (00:24:00)
JizzmopperSuggested correction: The tech is supposed to be highly advanced. This is at least kept consistent throughout the film as all communication between planets is in real time.
DetectiveGadget85There is no tech that can alter the laws of physics that we know of. This is unlikely to change between now, and the near future setting of the film. Your "correction" is no correction at all.
Jizzmopper"That we know of" - we also don't have the tech to travel to and live on Mars right now, do we? Use your imagination.
DetectiveGadget85We do have the technology to travel to Mars, we've done it more than two dozen times so far, we even have man-made objects roving the planet's surface. Given enough resources, we can send a manned mission to Mars in the near future. Faster than light communications, and travel, is scientifically impossible. In the context of the film, this is a valid mistake. Nothing in the film suggest the invention of made up technology that defies known laws of physics. And to suggest that somehow in the near future we develop the ability to communicate faster than light before the ability to attempt to colonize Mars is too great of a stretch to be considered valid.
