Why not talk about... portals?
(Not related to Valve's Portal).
I'm not a physicist, and I have a lot to learn yet. But, isn't this "wormhole" idea a little too much absurd?
Why not think in wireless communication instead? What if matter could be converted to specific waves and then transferred perfectly to any "receiver" (And then converted back)? It's a concept much different from "wormholes". It would work much like radio. Is this idea widespread? (I have no idea), or everyone always think in "wormholes"? (I guess it would not work exactly like in the Valve's game, considering the "conversion time". So, it would end up being more like a "teleport" instead of a portal.)
