As a thought experiment, I have attempted to calculate the time it takes two point masses to collide solely due to the force of gravity. The final answer I got was this:
[tex]t=\frac{R^\frac{5}{2}2\sqrt{2}}{5\sqrt{G}\sqrt{m_1+m_2}}[/tex]
Where G is the gravitational constant, R is the distance (at the beginning) and the m's are the two masses. It is assumed they begin from rest. (relative to each other).
Is this correct? If not, I can post my steps when I'm done with work. How sad is it that I've spent my lunch break doing this?
