Wow, I'm not sure that I can think of pretty much any of this movie as being real world physics.

At one point they say that the moon is having more effect on the planet that it is supposed to, so "Doctor conspiracy" says that they haven't accounted for its extra mass! If the mass of the moon wasn't what we thought it was rockets wouldn't get there when we tried and the obit would be completely different.

At another point they take off in the shuttle and are actually underwater, except the rockets are still working, just as much as they would without... So yes, rockets would work underwater, they are a mixture of oxygen and hydrogen, but the water would kinda suck all the heat out of the reaction, greatly lowering the thrust available. It would also provide a huge amount of extra drag to push against, killing any forward momentum that they may have built up by that point. Hint for any space racers out there... don't build your launch pad underwater.

Still if you ignore every conceivable scientific notion in the movie it's kinda fun. It's rather good to see an English accent in a movie without them being the bad guy...

On a side note I was watching this at one point the whole movie stopped mid-shuttle launch (Like pressing the pause button on a you-tube video). Cinema staff then came in and told us that part of the building roof was falling off and we had to leave. That's was the end of that for more than a week. I saw it again in a other branch of the same theatre a week later.

How much of it was destroyed in it going nova and producing the white dwarf (I didn't say supernova). The issue I had was that NASA tried to work out some orbital mechanics in launching the shuttle and they didn't gibe with what was going on at the time. Dr Conspiracy then chirps in and says "that's because you haven't taken into account the change in the mass of the moon". Why would the mass of the moon have changed? Moving it closer doesn't change its mass in any way. Suddenly finding out it has a star it it doesn't change its mass in any way.

The only way I can think of the mass changing would be some sort of hyper advanced physics we are not aware of that produced an anti gravity effect to mask the mass of the star, which stopped working once the star was covered by the AI and it lost power. Even if that was true, there is no way that Dr Conspiracy knew this at that point in the movie.
