An idea worth spreading
If we classify our world to 1) metaphysics 2) laws of physics & 3) physical part of the world, where consists of mass and energy, SPACE and TIME are parametrs of part 2, i.e. laws. Simply, these are not physical entities. So questions like : "Where is the end of SPACE? Is it finite? Is there any end to the TIME?" are not valid questions! Time and space do not exist independent of existing masses and energies. So the (reltivistic explanation of gravity by) curvature of space is just mathematical, not a physical phenomena anroud masses. This idea leads to this point: the distance between two imaginary singular objects is not a basic/independent parameter. The distance is equal to the delay of information transfer at speed C.
