“The Core” was just as bad as “Battle for LA”. Don’t these people know that scientists watch science fiction? The science was terrible!
In the movie your car wasn’t effected by an EMP pulse if you would pull over and take the keys out. But if you are driving then your car will generate a lot of sparks and you will die and your body will be charred in the seat. And of course you can replace the starter and battery of a douce and a half with parts from a car after EMP doom and it will start again.
All the submarines in the world were useless because of the EMPs that keep happening, all except for an old Russian sub. So they take a pair of 100 megaton nuclear bombs, that fit in a 4x4x8 wooden crate that can be lifted by several people, all the way to the bottom of the Mindinao trench. When they reach the bottom they release the bombs and they have 10 minutes to hide in the steam plume of one of the many volcanos that populate the trench, which saves them from the compression wave from the blast. And the trench was so narrow that a big rock fell on the sub at one point.
Yikes
The best part of The Core was Rat(the hacker) asking for Hot Pockets. “They help me concentrate.”
