Firstly, that little speech the physicist gave to the class about sound traveling through rocks? He says something about the wavelength increasing (ding right), and then says the frequency will decrease (bzzz wrong). Frequency stays the same regardless of the medium it is traveling through. It is the wavelength that will in fact decrease.
Secondly, what's with the explanation of how the Earth is going to end? Burning a peach with a deodorant can? Come on, I know military people are considered no-brainers, but he was demonstrating this to the people that lead a high tech organization. This patronises any military personnel, as well as the audience.
Thirdly, The premise of the film is based around the effects that occur because the core of the Earth stops rotating. Let me just first note that there are geological records to say that the magnetic field has changed direction many times in the past, with evidence to support that each time it has been reduced close to 0. To the best of my knowledge, and that of every history book out there, this happens without any of us combusting like the peach.
Fourthly, the scene with the golden gate bridge heating up because of a hole in the magnetic field? I think someone got magnetic field and ozone layer mixed up. The idea of punching a hole in a field is absurd. The field may be weakened, but the atmosphere would still protect our little bridges from cosmic radiation.
Fifthly, there is a force field (magnetic) around the Earth, not much of one, but there is one, not an "electromagnetic energy field". An energy field would do sweet f*ck all to deflect radiation. The same radiation that is supposed to wipe out humans like the peach...
Sixthly, 5 200-megaton nukes? Come on, those would weigh about 250 tons together. Let's try transport that on the dildo shaped 'virgil'. And the computer simulations of how they would be set off? All in 1 spot? That wouldn't create the required rotational force, since there would be no rotational force due to symmetry. He finally gets it right in the end to place them apart from each other. How they initially overlooked this one, I have no idea.
Seventhly, the material used to withstand all the pressure and temperature on 'virgil' was called 'unobtainium'. nuff said.
Eighthly, assuming we just spent the entirety of the world's budget on developing paradoxically copious amounts of unobtanium, it would take another 10 budgets over to have the resources to "control" the internet.
Ninthly, when 'virgil' was tunneling downwards, why could the people walk around inside as if it was horizontal? They mentioned the rotating bridge, but didn't mention anything about rotating hallways, or the rip in the space-time continuum needed to walk straight between the bridge and the subsequent hallways. The compartments would need to rotate individually, which would put them out of alignment with each of the other compartments. Logically, they would be aligned parallel for everyone to be walking horizontal, and not fall to the front of the ship, as the front is pointing towards the centre of the Earth. If only they could pretend virgil was round, and the entire inside could rotate as one. A pity every shot shows a long cylindrical ship incapable of this.
Tenthly, the giant geode that they crash into? All that pressure, all that temperature? But if that wasn't enough, they get out, and walk around. I know those space suits they had on looked cool, but they couldn't withstand the ~1000 degrees of temperature, and a few thousand kPa of pressure that is needed to keep the geode from collapsing under the weight of the world.
Eleventhly, when the ship springs a leak? It would have been like a nuke going off in the ship, but instead, it took a few minutes for the compartment to crush.
Twelfthly, the unlucky guy that has to walk through 9000 degrees temperature in a suit only designed to withstand 5000 degrees. He makes it to the duct and switches the lever? 9000 degrees is about 2-3 times the temperature of a nuclear bomb going off. I think the walls and floor of the corridor would have been glowing white with heat. Our man would have been vaporised, but lucky for him, only his converse pumps melted to get to the lever.
Thirteenthly, the guy that pulls out the plutonium rods undergoing fission? He didn't even have a helmet on. $10 says his kids will have 5 noses, 3 mouths, and a foot coming out of their heads. I guess it's a good thing though that the DNA of such a twit is wiped from our society in these industrial accidents.
Fourteenthly, when the power cut out from the lack of reactor rods, they hook up the power cables to the inner hull. Where do they put the ground? There needs to be a potential drop for power to be gained, and if there was a ground, then anyone that touched the hull would have been electrocuted.
Fifteenthly, the arming code for the nukes was the first four prime numbers... 1 2 3 5... Pretty sure 1 is not a prime number.
Well, thats about all, and thats not even going into the fact about how the core could stop spinning in the first place. Thanks for your time.
