This question is, once again, open to all.
Some time ago, I read this book on space being curved by gravity. The stronger the gravitation, the greater the degree of curvature. No problem with grasping this. Big question is...................am I supposed to abandon my previous understanding that a spacecraft or planet's orbit is a balance between gravity and centrifugal force? Or the freefall thing where the spacecraft is always falling to earth but the curvature of the earth always recedes?
