The Core

Corrected entry: When the vessel entered the geode (the great big empty hole), the crew was forced forward by the falling of the ship. They should have felt weightless - the ship was in free fall just like the "Vomit Comet" used by the Air Force to train astronauts and by Ron Howard to film Apollo 13.

Correction: Free fall would only happen once all the relative velocities were equal, until then they would be pushed back into their seats.

The crew was falling along with the ship, equalizing their velocity thus free fall happening.

Corrected entry: Considering the nukes would be crushed by the pressure and heat in the Core, how exactly did the team plan to set them off WITHOUT having to detach the compartments in the first place? They couldn't simply seed them by "dropping them out a hatch".

Correction: Because there was a pod designed already for them.

Corrected entry: When Josh and Zimsky are briefing the military on the ramifications of the core stopping, they state that after three months, all electronic devices will fry. It takes three months to build Virgil, as stated by Braz ("I built this ship in three damn months") and yet on the surface all electronic devices are working fine.

Correction: Josh simply says "in a few months every electronic device will be fried" while presenting his findings. Se was not being 100% literal, nor does the word "few" when used in that sense HAVE to mean 3. Furthermore, everyone is dealing with a completely new phenomena. So it is certainly not inconceivable that Josh was off a bit in his calculations.

Corrected entry: At the very end of the movie when the credits are rolling you see a panned view of the earth. The earth is rotating the wrong way. (02:00:50)

Correction: This is intentional - yes, they did manage to get the liquid in the center of the earth spinning again, but evidently calculated something wrong, because they got it spinning in the wrong direction.

Corrected entry: When the crew are entering the geode, we can see the blue/purple crystals on screen and the empty space is shown as black. A minute earlier we were informed that empty space showed up as static and black patches were what they could not pass through. Apparently empty space is too dense to travel through?

Correction: It's not actually that empty space is too dense to pass through. When Dr. Keyes said that "I never taught the computer how to read empty space.", he may be implying that he did not program the computer to detect empty spaces, thus the computer does not know about empty spaces and probably mistook them as solid.

Corrected entry: When Drs. Keyes and Zimsky are explaining to the military guys at the Pentagon what is going to happen, Zimsky is wearing a wedding ring (or at least, a ring on his wedding finger). There is no reference to him being married anywhere in the movie, nor is he wearing a ring in any of the other scenes.(The ring is probably Stanley Tuccis since he still was married at the time of the making of "The Core")

Correction: There is also no mention of him being single that would cause this to be a mistake. Just because a wife (or ex-wife, some people still wear their rings) is not mentioned, doesn't mean she doesn't exist. Also, because he seems to be somewhat of a womanizer, he would be less likely to mention his wife.


Corrected entry: When the ship first launches, they switch on the headlights. They use a special device to see outside the ship, and the ship has no windows, so why does the ship have lights?

Correction: Because the ship uses cameras, and the cameras probably use visible light to function. They were first entering water and you can see the light projected from the headlights lite up the water around them and on there screens, that light is what the cameras pick up.

Corrected entry: In the scene where Serge and Dr. Keyes first walk into the room with all the dead bodies, you can see that the number on the HMMWV says 69. Not only are these placards rarely ever used in the military, you'll never see one that says 69 unless a soldier is playing a joke.

Correction: None of which makes it a mistake. One of the 5-ton trucks here on base has the same numbers on it, and although I'm certain it is a joke that doesn't make it a movie mistake as it is possible for someone to have put those numbers on it.

Corrected entry: When the UH-60 Blackhawk helicopter is landing in front of the hangar at Brazz's hanger, you can see sand on the wheels. Its as if the part of the Blackhawk you see is a model and they've practiced the landing numerous times, because any sand on the wheels would certainly have gotten blown off in flight. (00:28:30)

Correction: I'm a US Army UH-60 Blackhawk crewchief, and have been for 8 years. You're wrong. You'd be surprised by how much sand, mud, dirt, etc,. sticks to the landing gear during and after flight. If that was a model they were jumping out of, it was -extremely- detailed as far as the gear itself and the aircraft underbody. Far beyond what would be expected of any movie budget.

Corrected entry: While in the geode, you can see that the giant crystals are twinkling and there is a definite source of natural looking light. Being as light has trouble penetrating through a few hundred metres of sea water, it would be fairly unlikely (impossible) for light to reach inside a sealed geode a few thousand miles beneath the surface of the earth. (01:03:40)

Correction: The light came from the external lights on the "Virgil". Light reflected from the original source to one crystal then another and so on.


Corrected entry: After the "Zimsky" bomb explodes, we see the mission control, there the core is fully rotating again, and everybody is cheering. But the 30% bigger bomb hasn't even detonated yet, the one that is definitely needed to "restart" the core. (01:49:55)

Ronnie Bischof

Correction: The 30% larger bomb detonates about the same time as Zimsky's bomb. After both detonate, the core starts turning again.

Corrected entry: At the very end of the movie, Rat goes to an Internet cafe to disseminate information via the web. As the upload starts from his laptop, his screen says "On it's way". It should be "its" (without apostrophe).

Correction: Programmer error. It happens. "You've got mail" isn't grammatically correct either.


Corrected entry: In the scene near the end where we see the ships looking for the Virgil in the ocean, the ships are close together in a nice, tight, circular formation. If they were on a search mission, shouldn't they have been spread out more?

Correction: It is known that the Virgil is near or around that spot were they are searching because of the whales swimming around the Virgil.


Corrected entry: There should have been a significantly reduced force of gravity experienced in the ship when it approached the core because there would have been a large mass of the earth above the ship as well as below the ship, and both sides would be exerting gravitational pulls.

Correction: We can safely assume Braz significantly modified his ship to counter gravitational pulls as you are suggesting.


Corrected entry: In the crystal chamber, they said the suits can hold the pressure. Therefore, the suits must be really hard. So how can a piece of rock go through Iverson's helmet? (01:07:25)


Correction: It goes through Iverson's helmet for the same reason a knife passes through your skin but a fist doesn't even if the exact same amount of force is used. The suits are able to resist pressure because the pressure is relatively consistent accross the whole outer surface of the suit, the impact of the small fragment however wasn't consistent, it was a large force applied to a very small area.

Corrected entry: At the end when Josh and Rebbecca are at the bottom of the ocean, she says they could be 800 miles deep. Being a geologist, Joshua must have known that the deepest point in the ocean is about 6.8 miles deep and therefore had to correct her. And that would be the Marianas trench. The place where they entered the crust. (01:54:45)


Correction: She says they are 800 feet deep but might as well be 800 miles deep. She's just pointing out how hopeless the situation is.

Corrected entry: In the EM tear scene, our first shot is a beam coming from the sun onto the earth's surface, and, as anyone can easily see, it is fairly wide. But, after that, when we see a tree dying, it first has an affection area of about 15 feet. 15 feet is invisible from space. (01:26:20)

Correction: When we see an outer space shot of the beam, you can see the beam getting through the atmosphere. So it's natural that the beam on the earth's surface has to grow too as soon as the hole in the atmosphere is big enough.


Corrected entry: When the Golden Gate Bridge is being destroyed by microwaves, we see a guy get 'sunburnt'. When he's looking at the sunburn, you can see that no one is in the car next to him. You may only be able to see it, if you're using the widescreen version. (01:26:55)

Correction: From the camera's point of view, you can only see the passenger's seat. So there's no way to tell if someone is in the driver's seat.


Corrected entry: Towards the end of the movie, when Dr. Keyes and Beck were going back through the earth towards the surface, they said they were going twice as fast as they were going when they went into the core. Now, judging from the speed Virgil was going when they were headed for the core and how the pressure on your body lessens the farther you go up, the lack of pressure should have caused the veins in their bodies to burst, causing them to die almost instantly.

Correction: They are also in a specially designed ship to take them there. It is conceivable that they stayed at core pressure all the way up and had to go through decompression after they reached the surface, similar to deep sea divers.

Corrected entry: When they are telling Rebeccah that she has exceptional navigational skills and is reassigned to the team they keep calling her "Major" but prior to that when the Army General is talking to her about how her crew crashed the space shuttle she has a silver leaf on her epaulette. Silver is Lieutenant Colonel, major would be a gold leaf. Major (Gold Leaf) is a step down from Lieutenant Colonel (Silver Leaf). Major is an 0-4, LTCol is an 0-5. Demoting an officer is a congressional act and it wouldn't have been done until the investigation was completed; she wouldn't have been demoted out of simple suspicion of the crash being her fault.


Correction: She was a Major the whole time, she was never wearing Lieutenant Colonel rank. I watched that scene as well as other scenes where she was in her dress uniform in slow-mo just to make sure her leaves were gold and not silver.

Dr. Josh Keyes: So what's this about then?
FBI Agent: We don't know. You have higher security clearance than us.
Dr. Josh Keyes: I have security clearance?
FBI Agent: Yes sir, we're just here to take you to your jet.
Dr. Josh Keyes: I have a jet?!



The geodes occurring in the mantle during the film are impossible in two ways. Firstly, there are no gaps at those depths. The pressure is approximately 3.5 million times surface pressure, and it is not feasible that such structures could form, let alone be maintained. Secondly, the crystals inside the geodes are described as amethysts. Amethysts are a purple variety of quartz, and as any undergrad geology student could tell you, there is no quartz in the mantle, it simply is not stable at such high temperatures.



If you look closely with time-frame advance during the pigeon scene you will see a fish "flying" into a window instead of a pigeon.
