Base on a true incident.
I was Treking in a Star Ship and made it to a check stop planet trillions of miles from earth here it is to detect and to destroy infiltrators from earth who may have slip their hold due to outer place. I signaled my satellite laser sentry's on frogman and spiderman which where in earths orbit. The lasers fired one blue one red I could see it come from the far galaxy two laser beams the blue taking more of a curved it took almost two hours to arrive the frogman hit and clip but the spiderman sentry hit dead on and killed the two infiltrators. Meanwhile I could see the shock wave of a star ship I was on over tweenty five years ago pull threw the galaxy when I first set up the laser sentry's I sigh a sign of relief that I used the spider man sentrys it was beautiful in color and relief to terminate this awful foe.
So I could see the lasers coming at me at the speed of light my vision saw them two hours out coming from earths orbit. Which is faster?
