Why can't light overcome gravity in a blackhole? What causes light to be light? How can gravity affect energy? Does gravity affect energy? What factors affect gravity? Why is light, sound and smell not affected by gravity? In what way mass affects gravity? If gravitational wave affects light, how does LIGO prevent its lasers from being affected? What is light caused by? Does mass have an affect on gravity? Is space-time-light-mass-gravity related? Does light affect sound? Does light moves? Why does light bend when it comes near a black hole? How does gravity work, and is gravity a matter or something else? Why does light move? Light needs a medium to travel, so how does sunlight come from space? What causes gravity?
