Email From the Homo Sapiens Sapiens Inhabitants of Sol III (Earth) To the Presumed Inhabitants of Alpha Centauri Bb:

You're there?!  Thought so.  And with, say, a billion more years of evolution behind you than us. Even if, as is likely, you've developed along the more, shall we say, traditional lines of lizards and dinosaurs than of cetaceans and anthropoid apes (and you're a little slower than we are, and your brains aren't quite so compendious as ours are), you've had precious time to figure most of those things out which we, now, at this point in our evolution, particularly need to know:  (1) Immortality in the Flesh (How to Reverse the Aging Process);  (2) Cures for Cancer and Wasting Diseases; (3) the Secrets of Travel and Communication within our Lifetimes over interstellar and intergalactic Distances. We'd like this information, if you please, by return email.  We consider that, with our art and music (Monet and Velázquez, Bach and Mozart), you are already paid for it, but we thank you for it nonetheless. Expecting the favor of your reply in 8.48 years.

P.S.  If "sub-etherics" and the mechanics of "wormholes" are still not possible for you, we will gladly accept in their stead a detailed, step-by-step description of the process of acceleration at a rate of one G (earth gravity) for the first half of the interstellar distance we wish to traverse, followed by decelleration at the same rate for the latter half of the distance.  This, at least, will get us where we wish to go within our lifetimes.
