Space Studies Tuesday: Lesson 6: Electromagnetic Radiation

Lesson: http://www2.jpl.nasa.gov/basics/bsf6-1.php

Just one thought on this one--relief.  For some reason, I had it in my head that all the music, TV, YouTube vids, etc that we've been broadcasting were going to be heard by some alien race, but thanks to the inverse-square law, they are probably too faint to hear outside the "local" area.

Of course, that removed the argument that there is life out there, they have seen Jersey Shore*, and they have no intention of contacting us. Ever.


* My daughter picked this show.  I had Gilligan's Island, but that's too old.  My next thought was Parks and Rec, although I'm sure there are many worse than either of these.  Like I said, relief.
