The Core

Plot hole: How do they maintain communication between the ship at the centre of the earth and the surface? There's no wire, and radio waves can only travel any distance without obstacles, and the earth's crust would be a pretty hefty obstacle...

Factual error: The ship, VIRGIL, is diving straight down from the crust to the core. Although the interior of the ship pivots to make the cockpit perpendicular to the descent, the ship itself is "digging" straight down so when people move from compartment to compartment they should be climbing up and down rather than simply walking back and forth.

Continuity mistake: On the ship, Dr. Zimsky reveals that project DESTINI is an acronym and that the last letter is "I" and not "Y." (INI standing for INItiative). When Rat is at his computer, he goes to the website for Project Destiny, with a "Y" and not an "I." This same thing happens when the Project Destiny subtitle flashes across the screen.

Trivia: 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. (00:08:35)

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?!

Question: When Beck tries to dodge the huge diamonds, the ship gets a breach. Wouldn't that cause the outside material to spray into the ship's interior, given the intense temperature and pressure?

Answer: The inner-earth ship known as VIRGIL is comprised of multiple double-hull detachable sections. The outer hull can be breached, while the inner hull can maintain structural integrity just long enough to jettison the damaged compartment. When VIRGIL encounters the giant diamond field, the very last section (the weapons control compartment) suffers a hull breach, and it immediately begins automatic detachment. Dr. Serge Leveque, the nuclear weapons expert, sacrifices himself by saving vital weapons deployment information from that compartment just before it detaches and is destroyed.

Question: If the core stopped spinning, where would all the kinetic energy that keeps it spinning go? Energy cannot be created or destroyed.

Answer: For one thing, the rotation of the core is almost identical to (if not a bit faster than) the rotation of the rest of the planet; so the core coming to a stop relative to the rest of the planet is physically impossible. Over billions of more years, the Earth's core and mantle may eventually cool off and solidify (as has happened on Mars), but the core will still be rotating at the same velocity as the rest of the planet. By that time, of course, Earth will have also lost its Moon, so there will be no tidal forces between the Earth and Moon, which means the planet will be seismically dead, but the Earth will still be rotating on its axis. For the time being, though, it would literally take a miracle, an act of divine intervention, to overcome the physics of planetary rotation. If the core could somehow be stopped relative to the rest of the planet (which is physically impossible), then the core's energy would quite quickly be dissipated into the Earth's mantle, which would become an unimaginable inferno (much more so than it already is), propagating seismic and super-volcano activity all over the globe by a factor of, say, 10,000 times normal activity. The Earth's crust would be effectively ripped to shreds by super-earthquakes and eruptions within a matter of hours, perhaps even causing the entire globe to disintegrate into space. As mentioned, though, it would require something on the order of a true miracle to precipitate this chain of events.

Answer: The same place it goes normally: dissipated into the Earth.

Question: The heroes manage to get the core spinning again by detonating 5 200 megaton nuclear bombs. In real life, wouldn't it take hundreds of 200 nuclear bombs to get the core spinning again?

Answer: No number of nuclear weapons would have an effect on the movement of the Earth's core. The bombs in the movie are just there as part of the plot. The Core is a hysterically unscientific movie. It's still great fun though.
