I would call it a satisfying consequence of General Relativity. GR explains the mysterious reason behind ##M_i=M_g##, not the other way... -

No. But the current understanding explains why the exact same mass is appropriate in both equations. That is one of the strong points of... -
MMike_bb replied to the thread Undergrad Why is gravity a fictitious force?.From ##M_i=M_g## we can conclude that gravity is fictitious force. Right?

MMike_bb replied to the thread Undergrad Why is gravity a fictitious force?.Ok. If gravity was force then mass of object (gravity mass) in elevator on the surface of the Earth differs from inertia mass of object...

We don't. Newtonian gravity respects the equivalence principle, and that models gravity as a real force. However, if gravity (in... -
MMike_bb posted the thread Undergrad Why is gravity a fictitious force? in Special and General Relativity.I read about equivalence principle. I tried to understand Einstein's thought experiment with elevator and I can't understand why we...
