Is there any case where the ratio of gravitational mass to inertial mass is not or could not be 1?
Is there a gauge theory for gravity? If so, what deductions can be made on the known models of gravity using it?

A place for physics students of any level to discuss the intricate profoundness of the universe.
I though you guys might appreciate part of this project I did at university, identifying all main sequence stars within Pleiades. Each red dot is a star! There are thousands!
For those inquiring about astrophotos that are always the Pleiades, also known as the Seven Sisters or Messier 45. It's made up of several hundred stars, including six or seven that are visible to the naked eye. The Pleiades is located about 400 light years from our solar system and is about 35 light years in diameter.

In the case of the Kerr metric, for a high enough angular velocity such that on transformation to Boyer-Lindquist coordinates yields complex coordinates for the event horizon, why is it assumed then that the coordinates "disappear"? are complex coordinates completely outlawed in physics?

If the acceleration caused by gravity is what causes the curvature of spacetime, isn't the fact then that the convergence of geodesics due to curved space is responsible for gravity circular logic?
