Why does light move?
Does light moves?
What happens when we switch on the light? What happens to the photons when I switch off the light? What happen if we moving with the speed of light? Does gravity affect light? Does vision travel at the speed of light? Will the speed of light ever change? What can move faster than light? Can we see light? Does a moving photon have mass? What would happen if light didn't travel in a straight line? How does gravity affect light? Why does the pupil of our eye contracts in bright light and expands in dim light? When light is absorbed by a solid where does it go? What is this light? Can a photon be at rest or does it have to travel at the speed of light? How are light sails propelled by light, if photons have no mass? Does light affect sound? Light needs a medium to travel, so how does sunlight come from space? Does the Light Side of The Force ever lose? What will happen to us if we move with speed of light? Can the speed of light be increased? How is the wavelength of the light is increased when it is moving away from us(red shift,see description for further details)? Is there anything that moves faster than light? Why does light posses a dual nature of both wave and particle only and nothing else? Speed of Light: How fast can we move? Why do light bulbs blow out if you flip the switch too fast? What happens to molecules of a medium when light passes through it? How does light turn into heat? Can speed of light decrease? Can you travel at the speed of light?
