Wormholes in Space

[Sindri]

In a space game using wormholes for FTL what are good excuses to keep the wormholes in space rather than on the surface of planets.

Stable Wormholes may (possibly must) require massive negative mass equivalents (like negative Jupiters even for throats a few meters in diameter). Obviously putting that much negative mass on a planet would be disastrous.

A wormhole near a gravity well?! Are you crazy? [Hand wave. Hand wave. Hand wave.]

Wormholes aren't mere doors you just open and walk through. They are a severe curvature of spacetime. You might as well ask why we don't put a solar-mass black hole on the surface of a planet.

Why are you asking about this? Is somebody planning something like this? If they are you better 'fess up right now, buddy.

It's not really much of a handwave. If you can have stable wormholes at all, they are going to be extremely large negative masses. A planet would be repelled by them and they'd be attracted to the planet. It would be a really bad idea to put one anywhere near a planet you want to keep.

I read that triple hand wave like the Japanese body language of negation ... basically trying to waff the thought away like bad air.

Thank you, I think I'd like to still have a planet tomorrow. However you make wormholes there's got to be a lot of energy invested in them. The most energy, the bigger the kaboom.

Given that negative mass is so ridiculously exotic that you can basically say anything about it, could you just say that it's impossible to stabilize a wormhole too near another mass?

The traditional justification for FTL not being done on a planetary surface is that creating a stable wormhole/entering hyperspace/establishing a warp bubble/etc. is difficult, dangerous, or impossible within a gravity well above a certain threshold.

Oh and don't forget to Jedi Mind trick you players that "Stargate is not the show you are looking for" ;)

Are wormholes artificial or natural? If they are natural, then the chance of them randomly happening on a planet instead of the massive void of space is tiny.
If they artificial just say the wormhole generator can't be safety activated on the planet. I can even give you a technobabble explanation if you want.
