JamesF Posted November 27, 2011 Share Posted November 27, 2011 on Qi, Friday the question was 'what's the largest black body in the solar system?'And I think the answer (the Sun) played fairly fast and loose with what a black body is supposed to be.James Link to comment Share on other sites More sharing options...

Ptarmigan Posted November 27, 2011 Share Posted November 27, 2011 As Perrin6 said ^Some of the answers were :RichH "Oprah Winfrey", for which he was tuttutted by StephenF !AlanD : "Black hole", for which he recieved a -10 hoot penalty and was chastised by Stephen that if there was a black hole nearby we would all be in trouble. **CleverClogs Stephen then offered the "correct" answer as the Sun on the basis that the sun is the only object that does not reflect anything.Not quite true, as JamesF ^.Way back last century I remember radar reflection tests to detect Venus and the Sun.The only refs I have found so far areSolar radarandhttp://www.google.co.uk/url?sa=t&rct=j&q=solar+radar+stanford&source=web&cd=12&ved=0CCQQFjABOAo&url=http%3A%2F%2Fwww.space.irfu.se%2Fseminars%2F20051108_khotyaintsev.pdf&ei=w4XRTrTeBI64hAfuyN3EAw&usg=AFQjCNGH7k-GOqlDuKegE1L_urVFC-67MQ&sig2=iS-aQVJnw3P5xeX1xJjDOw** However I think I remember reading that some bigbang models predict many mini blackholes which may be common, wooo scary ! So Alan may have been correct after all. Link to comment Share on other sites More sharing options...
x6gas Posted November 27, 2011 Share Posted November 27, 2011 OK, so the sun is a real "blackbody radiator" IIRC (long time since I studied this stuff) but I believe that the definition that "every thing else in the solar system reflects light" therefore the sun is a blackbody must surely be wrong!?
