my knowledge of time-space is limited, so my question might be poorly/wrongly constructed/verbalized:
Do we have two sets of co-ordinate systems when space-time is bent (by say, mass)?
in one system the circle becomes, say, an ellipsoid
while in other it remains a circle?
in one system the photon continues to move in a straight line
while in other photon takes a non-straight path?
I mean there must be a "reference" system to compare and say the other one is bent
can such co-ordinate systems be called as frames of references?
