On the other hand, if you were to drop the same distance onto solid ground, you might break a leg. What is the difference in terms of Newton's Laws?In every derivation of the Schwarzschild solution I found, at some point the "weak-field" approximation is made. Nevertheless, the same solution is used to describe black holes, down to r=0. Why is this?In thrill machine rides at amusement parks, there can be an acceleration of 3gram or more.
