Plot hole: In the scene where they show how the earth's core has stopped moving and at the end of the movie where they show it moving again what instruments are they using to show these momentous events? According to the film, the inside of the earth is filled with various rock formations, huge diamonds and molten lava, not to mention intense heat, so what device(s) could sustain itself long enough to give back accurate readings?
