1) Just how small can a wormhole be?

2) What would the minimum size of a wormhole have to be in order to send a radio wave or laser through it?

3) What would be involved (in broad strokes) in creating a wormhole? Would creating even the tiniest wormhole require something silly like the combined energy of an entire galaxy to produce?

4) Is there even a theoretical basis for determining where (not to mention when) a wormhole would go even if you assume you could make one?

5) How long would such a wormhole last? Long enough to send a short burst transmission? Forever once it's made?
