To explore opposing alternatives and to make the scene/event seem more vivid and realistic in the reader's minds.
It makes it not dark, or less dark, depending on the exact amount of light (lumens) used in the space.
The amount of light doesn't effect the force of gravity.
Glow in the dark stickers contain phosphorescent pigments that absorb and store light energy when exposed to light. When in a dark environment, these pigments slowly release the stored energy as visible light, creating the glowing effect.
Yes they do---the light has no effect on their growth
Light text on a dark background.
Since dark matter has mass, it is able to warp time and space, which also makes it able to bend light. The effect of dark matter on space-time (and, therefore, light) is the same as that of regular matter.
they have a chemical in them
Dark imagery is the use of darker, and colder words as opposed to brighter more friendly ones. For example Dark imagery could be like 'The castle had a frozen feel to it, within the corridors lurked the most vicious of creatures, as if to reflect the owner of the castle, this place is more of a cage to me than anything, the my fingers tremble in the merciless cold, No one is coming, no one ever was, and until then I will tremble, pathetic, dirty, repulsive, creatures that roam the atrociously ugly creatures dying from the inside out, creatures that cannot ever blend in, join the group, always to stand out and be forever looked over, creatures like myself' the ending provides a terrible and hopeless image to forever bathe in the darkness and brings darker and lonelier feelings into the mind of the reader.
By definiton, "dark" matter neither emits or absorbs light. Thus, it does not effect the brightness of galaxies.
It gets dark and cold(because there isn't any light or heat from the sun)
Do you mean chiaroscoro? which means light-dark. Mostly for dramatic effect
No, glow-in-the-dark items, including splat glob, need to be charged under direct light to emit a glowing effect in the dark. The glow will fade over time as the stored light energy diminishes.
