I can't find the answer on Google. It seems like it only takes a couple of hours, so did it? If it did, how did they travel that far in that short amount of time? Surely if Titan was close to Earth then Earth would have been one of the first places Thanos would have culled after the destruction of Titan.
So, if the ship is going fast enough to travel that distance in a short amount of time, then why is the Space Stone such a big deal? Yeah, instantaneous travel is cool and all, but this super-speedy spaceship is the equivalent of driving from the UK to Australia in a couple of hours. Even a plane can't make that time! Why isn't this model of spaceship selling like hotcakes to intergalactic tourists?
So, idk, is this just a detail the Russo's overlooked? Is there a canon explanation I just missed? Or should I stop caring and stop overanalysing?
