Double-A Einstein also told us if you went at "c" you would be every
where at once. Wheeler and Feynman even wrote a tongue and cheek paper
on one electron traveling at "c" and being every where at once so that
one electron was all the universe needed.That is playing around with far
out thinking. I myself have had thoughts that the universe only needed
one "graviton" that was instantaneous and was the source of gravitation.
Just bouncing thoughts around,and gave it up because it did not fit
