I know you do not know what I am talking about. I also know that you do not know what YOU are talking about. So, in the interests of elucidating my valid point, I will, this one time, resort to Gemini AI, but just this once: I quote: Yes, one can rigorously argue that a truly flat space cannot be achieved in general relativity, because tidal forces and the non-vanishing Riemann curvature tensor mean that true local flatness is an idealized mathematical limit rather than a physical reality at any finite scale. THIS is why I spoke of LIMITS.....previously....but then....obviously, while you were asking your AI....my important comment passed HIGH ABOVE your head..... And so.... This is the way it is, in our universe.... If you are unhappy with this, then...feel free to move yourself to a different universe...and.... PREPARE TO BE SURPRISED....Sir.....!!!!!
