I would like to state that Dale's musings are in fact worthy of fair consideration. Another million years or so of scientific endeavor might well produce many understandings of physics and science that we do not currently have awareness of.
For example, antigravity might well be feasible if gravity operates in a principle similar to radio waves, perhaps by distorting the orbits of electrons around the nucleus.
Similarly, consider the possibility that accelerating to near light speed, may in fact make the traveller experience very little time lapse during the travel that might seem like a much longer time to observers who are stationary. Now consider that a black hole at the center of our Mily Way galaxy is based on pyhsics not well understood where incredible mass is concentrated in a tiny volume. We may not understand the physics of black holes, or how gravity works at a sufficient level today for a physics class, neverthelss, there are many things we do not yet understand. But if nonlinear physics exist that make travel at speeds faster than light speed, or make the distances able to be much smaller in some sense, then galactic travel may be feasible.
Furthermore, the pace of scientific evolution may be quite different for any hypothetical civilization living closer to the center of the galaxy, than a civilization far out in the outer regions of the galactic spirals, like our solar system. The inner regions of the galaxy experience a much broader range of physics than we do in our solar system.
As for intreraction with humans, consider that such interaction may involve much higher purposes than we are aware of. Perhaps a characterization of all galactic life forms and the corresponding genetics. Perhaps characterizing the evolutionary pace of life forms on galactic planetoids versus physics properties of the eneregy from the nearby solar energy source.
To consider other possibilities, sure, its also possible that one or more governments have very secret physics projects that we have no awareness of or understanding of.
Net-net, I agree with Dale, dont be too quick to dismiss those things we do not understand.
(Sorry for ending several sentences with a preposition).
PS. Happy New year to all of you!
