comment Why earth looks always flat when it is round
I am a microbe. I live on the surface of a bowling ball. I am convinced it is perfectly flat.

comment Can bad guys really hide “dirty bomb” material via bananas?
@dmckee Agree! It happens too often that I try to to enjoy some movie or TV show, and some event has me mumbling "Oh, bull$&!+." and ruins my 'suspension of disbelief.' I suspected it was unlikely, but this one left me scratcing my head. I guess I hadn't made the mental leap between this quote from the link in my question: "the radioactivity from a truckload of bananas is capable of causing a false alarm when passed through ... " and the much stronger statement "if said truck contained a Goiania-like device, the authorities would just assume it was due to the bananas and wave it through."

comment Can bad guys really hide “dirty bomb” material via bananas?
@dj_mummy While that was the story line of the episode, I'd like to hear a more general explanation (positive or negative) of whether bananas can disguise any material that could be used to build a "dirty nuke."

comment Is there anything special about the Sun's photosphere in terms of density?
@John: The wikipedia article does address a part of my question, thank you. And I hadn't known about the Shock Front previously, which is very interesting. However, it does not get to my specific point, whether anything special goes on at the photosphere.
