Re: Wormholes in Space
Orbits are okay, you know . . . in orbit. But
a wormhole in orbit at the altitude of a planetary surface will proceed to become a tool of digging and demolition. |

Re: Wormholes in Space
The other likely reason is some reasonable concern about what happens if the wormhole isn't quite as stable as you thought. If collapsing an expanded wormholes would release enough energy to vaporize your planet, you might not want to put it there even if you were pretty sure that would never happen.

Re: Wormholes in Space
"FTL works" is already magic. Adding a little more magic won't hurt anything.

Now, it is quite likely that the mass will be very large - the mass of Jupiter, the mass of a million suns, something like that. This depends on the particular implementation of the wormhole. |

Re: Wormholes in Space
Do you know where I could get information on traversable wormhole mass requirements by implementation?

Another nifty thing - if the topology of space-time cannot change, you can pump massive amounts of energy into a tiny speck of it to initiate inflation, and then this universe will always be connected to the universe you just created with a wormhole. Use time dilation tricks to wait until things have quieted down and you have stars and planets and stuff, then open up the wormhole to see where it goes (there are ways to propel and steer wormholes from the other side, making use of time dilation effects to mean everyone at home doesn't have to wait long even though the wormhole on the other side might experience thousands of years of proper time en route to its new home). At this time, we have no experimental or theoretical justification for preferring topology changing versus non-topology changing physics. Luke |

Otherwise, note that the Visser wormhole (a "two dimensional" "window" or "gate" wormhole) and its extended generalization, the thin shell wormhole (a "surface" that acts as a wormhole) has exactly zero mass in the far field. This is probably unstable, but from this you can add mass to whatever your story or setting needs (and adding mass will get rid of at least some of the instabilities leading from quantum "Ford- Roman" effects).
