It is absorbed by the objects around it, or in outer space it keeps flying away at 186,000 miles a second basically forever.

I don't exactly know if you understand how a light bulb works. An incandescent light bulb works by running 120 volts of electricity through a thin piece of metal (usually tungsten). This makes the metal glow and it emits energy (made up of photons and heat). The light bulb contains argon or another inert gas or a vacuum so that the filament (the metal) doesn't burn away. So, when you turn off a light bulb, no electricity goes through the filament, which means that it doesn't get energised, which means that it doesn't emit photons = no light.

The light is absorbed by its surroundings and all goes dark.
