Obviously, we wouldn’t be able to travel the trillions of miles to visit these planets...which are only faint dots on a monitor at this point...and indeed: they have yet to find a planet out there that seems like it could support life...but...according to this quote of a quote via AP science writer Seth Borenstein:
It's only a matter of time before "we get a dot that's blue and Earthlike," said astronomer Bruce Macintosh of the Lawrence Livermore National Lab.
If we can receive an image of the place, we can receive light from the place right? ...we could receive signal from the place...we could send signal to the place then, logically, right? We can’t get our bodies back and forth to there. But we can get some signal going back and forth.
Linguists and code crackers could decipher their signals maybe. Maybe a common language could be formed. Maybe we could connect our internet with their internet, connect our satellite communications with theirs. Maybe we’ll be reading their blogs some day. How different will they be from us? Are there certain aspects and elements of society that are universal? Do they have elections? A left and a right? Do they have graffiti? Hackers? Maybe they’ll hack our communications. Are we worth hacking? Maybe they are already hacking us. Maybe they already have blogs on 'our' internet. Maybe my blog is one of them. Maybe I'm a space alien. You don't know. Maybe me and my pointy-eared, big-brained, compadres from the other planet are easing you into the idea, right now, that there are other bloggers out there on other planets.
