The Paradox of a "Straight Line"

 Here is something fun, draw a strait line on a sheet of paper slowly over a few seconds time. You can even use a ruler to get it as strait as possible. 

You think you drew a strait line, but the earth was rotating while moving around the sun, the sun is rotating around the galaxy, the galaxy is rotating in a local group whose size we don't know and the entire universe is moving and spinning in ways we can't even imaging.  That strait line you drew from an observer from outside the universe was wildly distorted, stretch for   tens of thousands  of miles and curving and rotating  in multiple ways.
