I was scanning through the wiki page about neutron stars to follow up the implied consequences of all those numbers. It makes good...

Which is also a crazy thought. I would have thought the force would have been more than enough to "make the golf ball dead" at that...

Yet, the golf ball won't deform very little, during the time it falls. The acceleration of the tidal force is only 400000/0.045 =...

It certainly is. But don't you feel better, having proved it? I should have done it in my head using a 10,000:1 ratio of distances. Plus...

Hmm. Let's see. I believe we can use the following equation for this calculation. ##F = \frac{GmM}{(r+h)^2}## If we assume that the...

You are making the assumption that the acceleration is uniform over the time of the fall. Obvs it works for a 1m drop on Earth but you...

This is much easier to calculate using the potential energy E = GMm/r: The released energy is ##\Delta E = GMm (\frac 1 {r_2} - \frac 1...
