There are 2 ways to answer this question. A: I could bore you to death with a 20-page essay. B: I could simply say that every point in the universe is lighted by the nearest star. Some parts of space are desolate of stars, and so they are dark and without light.

What is the universe's primary source of light?
Most of the light in the universe comes from the stars. Stars create their own light using nuclear fusion.
How far in light years is the most distant know source in the universe?
I dont know can someone answer it ?
What is a visible object that is not a light source?
A visible object that is not a light source is any other object in the universe. Objects that are not light sources reflect light and are thus made to be visible.Examples include:planetspeoplethe mooncarsdogsflowersbooksrocks, either in daylight, or else illuminated by a flashlighta light bulb or LED with the power switched off
Is speed of light a universal constant?
As best we can tell, yes. If Maxwell's Equations apply in all parts of our Universe, then the vacuum propagation speed of EM radiation (ie, light) will be the same in all parts of our Universe. We have no reason to think that our small portion of our Universe has different physical laws than other parts.
What does the umbra and the penumbra have to with with eclipse?
An umbra is formed when an object blocks all of the light from a light source. A penumbra is formed when light from one source is blocked with light from another source filling in some of the shadow, OR when a large light source is only partially blocked. http://www.learner.org/workshops/sheddinglight/highlights/highlights1.html

Are stars the only source of light in the universe?
no. sometimes planets are bright enough that light reflects off of them

Is the sun the only light source in the universe?
No, the Sun is not the only light source in the univrse. Every star is it's own light source, just as the sun is, but due to there distance they are not very effective. The Moon also creates a light source, because it reflects the light from the Sun back to earth. In the same way, if we where on the Moon, the Earth would be a light source, reflecting the light from the Sun at the moon.
What is the farthest light has traveled?
All across the known Universe.
What is the source of heat and light for all the plants?
The sun is the source of heat and light for plant-life.
What is the difference between light source and an illuminant?
The terms light source and illuminant have precise and different meanings. A light source is a physical emitter of radiation such as a candle, a tungsten bulb, and natural daylight. An illuminant is the specification for a potential light source. All light sources can be specified as an illuminant, but not all illuminants can be physically realized as a light source.
Are there any known fusion reactions in the universe?
Definitely. Nuclear fusion is the source of all the light, heat, and other energy generated and radiated by every star you see, including the sun.

Photons travel outward from a light source in?
the photons travel outward from a light source in all directions.
What is the main source of the universe?
The Main-Source.
