Wormhole the Moon through the Earth

[dQniel]

I'm working on a potential sci-fi story that takes place on a post-apocalyptic Earth. The idea is Something Horrible 1A happens, then, 15-20 years later, Something Horrible 1B comes to finish us off. In a perfect world, the Moon is gone after 1A.

Initial possibilities included a long orbit double comet (first hits the moon, destroying both and partially wrecking Earth), then the twin comes around (follows-up) a couple decades later to hit Earth and finish the job.

Then I started wondering what would happen if a wormhole experiment on the Moon went awry, wormholed the Moon through Earth to the other side? Would the energy/radiation of the event wreck Earth enough for 1A? Basically, what would happen to Earth?

Then, would it make "more sense" (in this completely science fiction scenario) for the Moon to return 20 years later near enough to the Earth to crash into it, or to reappear immediately in a 2 decade slow degrading orbit?

Regarding the comet scenario: comets are not large enough to destroy the moon. You need a minor planet - excuse me, dwarf planet. Were you able to destroy it, I doubt you could avoid total destruction of the surface biosphere of the Earth from the resultant debris. (It wouldn't take many of the remnants striking Earth to render it uninhabitable.)

Since your wormhole idea appears to be based more on the popular notion of wormholes and not on any of their scientific aspects then you could probably have its side effects be whatever you wish them to be. Is there a reason that you wish to use an astronomical source for your apocalypse? Why not jump on the global warming bandwagon and reach the tipping point where methane is released from the methane clathrates on the ocean floor: massive global flooding, destruction of ecologies, raging storms, intolerable temperatures and the end of test match cricket.

That sounds like a really interesting and unique concept for a sci-fi story! I think the idea of a double comet causing the initial destruction and then a wormhole experiment gone wrong causing further devastation is really intriguing.

As for what would happen to Earth in that scenario, it would definitely depend on the specifics of the wormhole event. If the Moon was wormholed through Earth, it would likely cause massive amounts of destruction and radiation as you mentioned. It could potentially cause a series of natural disasters such as earthquakes, tsunamis, and volcanic eruptions. The impact on the Earth's orbit and rotation could also have significant consequences.

In terms of the Moon returning 20 years later, I think it would make more sense for it to crash into Earth rather than reappear in a slow orbit. A slow orbit would give people more time to prepare and potentially find a way to divert the Moon's path, whereas a crash would be a more sudden and catastrophic event.

Overall, I think this idea has a lot of potential and I'm curious to see how you develop it in your story. Good luck with your writing!
