Science and space exploration have caught up to science fiction in many ways, producing marvels beyond the imaginings of the visionary writers of the past. Yet there are staples of science fiction that current technology is still leagues away from attaining, and which some doubt can ever be achieved.

For example, interstellar travel.

"'Beyond the solar system' is too far away," said Kim Stanley Robinson, author of the "Red Mars" trilogy and the upcoming "2312" (being released May 22 by Hachette Books' Orbit imprint). "It's a joke and a waste of time to think about starships or inhabiting the galaxy. It's a systemic lie that science fiction tells the world that the galaxy is within our reach."

However, NASA itself has said the idea is worth pursuit and has teamed with the Defense Advanced Research Projects Agency (DARPA) to sponsor the 100 Year Starship project to spur scientists to look into it.

I couldn't disagree more with Robinson. All one has to do is to carefully and objectively examine the voluminous evidence of unknown advanced technology flying around in Earth's skies. If even one of these objects is extraterrestrial in origin, then all bets are off. To read more, click here.
