Why Didn’t Our Ancestors Use EMP? Moonfall’s Unanswered Question

Moonfall film

Moonfall is a 2022 science fiction disaster film.

The world stands on the brink of annihilation when a mysterious force (swarm) knocks the moon from its orbit and sends it hurtling toward a collision course with Earth. That’s how the story goes.

Moonfall is a highly enjoyable movie. I really enjoyed it very much.

But it is said that as much as science was involved, logic was thrown out the window.

There are many unanswered questions and apocalyptic plot hole in the movie. But let’s talk about the biggest unanswered question:

Why didn’t our ancestors create EMP?

In the movie, we see that a military program code-named ZX7 had created an EMP (electromagnetic pulse) device in an attempt to kill the swarm (artificial intelligence), but was abandoned for budget reasons. Fowler orders the EMP to be brought out of storage and brings the retired Space Shuttle Endeavour out of its museum to serve the mission.

At last, EMP saves us all. This is interesting! Because I ask myself-

So a hyper-advanced alien civilization never developed EMP technology!

We shouldn’t call them alien. As per the film, they are our forefathers or ancestors. They were so advanced that comparing to them, we are at stone age now!

Another question may arise:

Why did the EMP kill the old AI but not the new AI of the Moon?

In the film, we see that a white dwarf is in orbit, around Earth, in a space craft the size of the moon. A billion year old AI is protecting Earth.

If the EMP kills the old disobedient AI, it should kill the new benevolent AI of the Moon too.

You can say that the new AI is EMP-proof.


The AI of the Moon can do magical upgrades to Stone Age tech but is unable to create an EMP weapon for that nanite swarm that can be killed with a single EMP.

To me, this is the biggest astonishing matter in the film.

Here is a review:

If they’re planning to set off an EMP inside the moon, then this is probably one setting where the cliche Hollywood 5-Star General saying “fire the nukes” makes more sense, as nuclear weapons are well known to create large EMP pulses, and don’t require a bunch of crazy hijinks.

Let me know what you think. Am I thinking too much?
