The light from this merger came in the form of gamma rays that followed two seconds after the gravitational waves, then X-ray, ultraviolet, optical, infrared, and radio waves emissions followed for days and weeks after the merger. This allowed scientists to track this event back to its home...
If light contained particles or simple straight-line rays, he reasoned, light not blocked by the opaque card would pass through the slits and travel in a straight line to the screen, where it would form two bright spots. This isn't what Young observed. Instead, he saw a bar code ...
