So, i was on the plane going for oxford interviews and i was thinking about what i could be asked. While i was thinking i came up with this one. Suppose the Earth and the moon were at a distance α apart at rest, how long would it take for them to crash into each other. I'm only really considering an ideal situation where the system is only comprised of the Earth and the moon. So i tried to solve it in general for two planets of mass M1 and M2 respectively.
If anyone could provide a method or a solution. I was initially going to type in my work but its going to take hours. if anyone wants to see it just pm me. ( mine involves conservation of energy and momentum and len gthy calculus. my solution is not complete as the function i obtained was so complex that i was too lazy to substitute everything in. thanks everyone
