Question

As you know, Mayans predicted a catastrophic event for 21 December 2012.While the nature of this event and the reason for this date were a subject of many speculations, the hierogliphs in the most recently discovered tomb of the Mayan warrior queen Lady K'abel [http://www.livescience.com/23680-tomb-mayan-queen.html ] answer some of these questions.

Apparently, on a day certain law of gravity will change so that the Earth will leave its orbit (assumed for simplicity to be perfectly circular) heading toward the Sun due to an 1/r^5 force as derived by Wilson.

The Earth is to hit the Sun on 21 December 2012.

On which day (precisely) the law of gravity would have to change so that this collision will indeed occur on 21 December 2012?

You will be close to the correct answer, if you prove that the change would have to happen around the 2012 U.S. Election Day.Your proof has to be purely based on physics which you learned.

Explanation / Answer

F=k/r5

a=k/r5M

r=0.5at2

t=(2Mr6/k)

r=earth-sun distance

k=force proportionality constant

M=mass of earth
