I understand this is a chain of dubious assumptions, but I'm not sure exactly where I go wrong with this line of thought. Thanks to Hawking, we understand that black holes radiate particles. Howev...

Suppose we have a gravitational wave which obeys the equation: $[G_{tt}-c^{2}G_{xx}]h_{\mu\nu}=0$ Lets take the case where $h_{\mu\nu}\ne0$ so we are left with the classical wave equation.Suppose...

Would a colony on earth's moon need to be deeply underground to ensure more natural gravity (by getting closer to its core)?
