Ethan Siegel discusses the assumptions about alien intelligence and physics with Dr. Daniel Whiteson.

An even grander goal that many of us have, including scientists and laypersons alike, is to find not just life, but an example of intelligent extraterrestrials: aliens that are capable of interstellar communication, interstellar travel, or even of meeting us, physically, on our own planet. It's a fascinating dream that has been with humanity since we first began contemplating the stars and planets beyond our own world. Most of us, including me, personally, have assumed that this latter type of alien would not only be more technologically advanced than we are, but would also be far more scientifically advanced as well. That not only would they understand everything we presently do about the fundamental laws of physics, but far more: that they'd be a potential source of new knowledge for us, having equaled or exceeded everything we'd already gleaned from our investigative endeavors. And that assumption, as compelling as it might be, could be completely in error, argues…
