This puzzle was more of a mindgame. You have only 24 chances during the puzzlehunt, assuming you make use of every 1 hour window.
We are presented with a standard physics problem, some simple information about Alice, Bob and Charlie from which we (supposedly) must calculate the mass of the sun. Of course, since this is a computer-based exam and the use of Google is always permitted (and encouraged) in the puzzlehunt, we may just google the answer and paste it in. Well, almost -- due to the large number of possible formats, only a few were accepted:
1.989e30 1.989e+30 1.989*10^30 1.989*10^+30 1989000000000000000000000000000
Whitespace in sensible places was also allowed, as were extra zeros, and (most) mathematically correct variants of the above. A tolerance of 1% was also accepted. Unfortunately it seems one team were denied their (correct) solution due to using the form
1.989x10^30 instead. (The use of x or × is now accepted.)
