I don't understand why we are able to see and measure curvature / warping of space at all.
Space as I understand it determines distances between objects, so if space were "compressed" or warped, shouldn't distances be compressed or warped the same way (like crumpling up a sheet of paper) ?
Then, however, our units of measure and frames of reference should be compressed likewise so that there should not be any visible changes to our cognition.
This would also rule out warp drives unless they form some wormhole in hyper-space (analogous to two points touching each other on the crumpled sheet of paper)...
What am I missing ?
