A photon can not be if it did not move at 186,242 mps. An electron could
not be if it did not spin at 186,242 mps Spin is curved motion,and it
creates curved space. Nature uses this curving to create inertia,and
gravity. They are the dog chasing its own tail. Inertia and
gravity are the same force. All this fits nicely with my "Spin is in
theory" I also can show how nature can use spin "up" or spin "down" in
her balancing act. That is my "concave & convex theory" If I had only
two words to describe the universe,those two words would be "Curved
motion" Bert
