Hello everyone. I am new to the physics forum so bare with me. Thanks in advance.
I would like to create a compelling argument for or against the title of this thread. To this end I would like to start with some questions about distance.
How does the curve of space-time relate to the distance from the 'bottom' of the gravity well to the 'top'? Do we measure the curve itself? Do we draw a straight line underneath the curve, from the bottom of the well to the top? Or Do we start at the top and measure horizontally across till we are directly above the center of the well?
Or, and I fear this is the most probable, is there a far more complicated method?
(I am well aware that a gravity well's space-time curvature is more analogous to a Density, with the object of mass at the most dense center point. But I'm am using the common 'bowling ball depression' description to make the question's language more accessible.)
I ask these questions to get an answer to weather space-time grows or stretches when bending. Considering the bowling ball on the bed, the bend that occurs pulls the sides of the bed inward resulting, in a topographical sense, with more area of bed existing around the bowling ball. Considering space does not have an 'edge of the bed' one could say then that space 'grows' around bodies of mass. The statement 'Mass creates space' does not fall easily on the ears of most knowledgeable physicists.
I must restrain myself from asking anything more until the first few are underway. Please feel free to get technical.
