Thank you Moderator Evan for being understanding.but permit me to post correct different title, re- :"Why speed of light is constant at 186,000 miles/sec., forward, backward, sideward" It is like this: all space, outer space and space on earth, is completely filled/occupied by the frame of spacetime which is electromagnetic. That is why, source of light, together with the orbit of earth of 100,000 miles per hour, such light travels at 186,000 miles/sec. forward, sideward, or backward. This is what Michelson-Morley , with the use of interferometer, found out. Point the interferometer forward and the speed if light is 186,000 miles sec.., point the interferometer at the rear, and the speed of light is same 186000 mile/sec. Thus, the scientific community, including Dr. Einstein, concluded, light is independent from source. But the real explanation why the speed of light is constant is because t the whole outer space is electro-magnetic medium. thus, wherever the source of light is, where ever its direction, it is always on the all encompassing electro-magnetic medium of spacetime. jsa 43.4.19. .
