Lovely to look at but a scientific dud


i. The science in this was laughable. Travel to the outer solar system takes 79 days? Sheesh, 2001: A Space Odyssey, was more accurate over 50 years ago. Such a trip will years and years... maybe decades, even with advanced propulsions being contemplated. (To be fair, most people can't conceive how vast and empty space really is. It's called 'space' for a reason... there's lots and lots of it.)

ii. And, it was a good thing that Neptune was on our 'side' of the solar system and not on the far side. That would have forced Pitt to fly past or through the Sun itself.

iii. No attempt made to accurately portray the reduced gravities of the Moon and Mars except for the dramatic "driving-off-a-cliff" bit. Everyone moves exactly like they do on earth. But they take pains to portray the weightlessness of space for dramatic impact.

iv. Things in space don't "drift off" like they are in a current of water. Unless they are pushed, they will simply carry on traveling along their current orbit or trajectory.

v. On the way to the outer solar system, he flys close past Jupiter (Saturn too IIRC but could be wrong...). Planets don't conveniently line up like signposts along a route. The outer planets line up every 12 to 175 years, depending on how many you are considering. The probability that Pitt would pass any other planet on the way out is minute.

vi. The whole concept of the Surge is shaky too...these pulses of energy would have to be YUGE to be felt back at Earth. Consider that the Sun -- athe biggest source of energy in our immediate part of the galaxy -- is only 8.5 light minutes away, a fraction of the distance between us and Neptune. But that radius is enough to reduce that energy to the point where we'd only get maybe a bad sunburn after a few hours on a beach.

Yet, this energy pulse from the outer solar system, knocks out all sorts of electronics on earth.

Okay, it's a piece of fiction, but these days even a lay person would be able to call out some of these inaccuracies.

Since its purpose was entertainment, I'm not bothered that it wasn't a documentary.
