having just read Michio Kaku's interview about what scientists hypothesize about Type 2 and 3 civilizations, he says that these beings will be able to manipulate space-time the way you or i would manipulate a wet washcloth... so i would imagine these Type 2 beings would be able to materialize when they are on planets that have a specific gravitational pull, and when they are travelling between universes they would naturally dematerialize and let their minds control and navigate any "space craft" they might be travelling in. maybe they'd have "2 legs" or "2 eyes" when they assumed a terrestrial form, or maybe they'd be able to shape themselves into something that would not look out of place to a native of some exotic unexplored planet by taking in soil and atmospheric samples, and running them thru some kind of analyzer. then Type 3s would basically be shapeshifters and could assume any size or shape they needed to be depending on which kind of environment they happened to be in and they wouldn't use handheld tools to accomplish these feats, they would just have to think about them and *voila* they've morphed again, like interplanetary chamaeleons...

just rambling and imagining .. hi all..i'm new here.
