It should be obvious to anyone that this guy is making it up as he goes (long hesitation, vague answers), but in case you really need proof he fucked up his LARP with the Mars spaceship thing. He claimed spaceships that travel just under the speed of light would take a day to get to Mars, but even at half the speed of light in the farthest scenario it would take under an hour. Sadly the interviewer seemed to know this and tried to help him out, but for some reason he decided to correct her with the wrong answer. I'm supposed to believe that the guy who studies string theory and timeline convergence doesn't know how long light takes to get to Mars?
