Were that the case, it would have been the iceberg that sank, not the Titanic. Ice floats in water because it has a lower density than water... It is more solid, but has a lower densityOriginally Posted by bobf279

The full force formula applied to all 3 pairs of bodies gives a net acceleration of the Earth (in 1/r^2) biased towards the heavy ball. The force between the balls give a component to each of them in the direction of Earth (in 1/r^4), biased to the light ball.
Without more detailed analysis (and detail on the setup) seems to me the 1/r^2 would trump the 1/r^4 and the heavy ball would touch down first![/quote]
You and every other scientist. The pheonmonon was forst recorded by the ancient greeks and has remained a mystery ever since.
Here's another.

The Reimann Hypothesis. Simple question, prove whether it is true or False.
The Prize: At least $1m, Probably the Nobel Prize for Mathematics plus many more accolades.
OK hands up all those who understood The Reimann Hypothesis :-? :-? :P
