Light does not have mass. Remember, as an object's speed approaches the speed of light, its mass approaches infinity, therefore it will require infinite energy to accelerate something to the speed of light, therefore only massless particles can travel at light speed.

Does venus create its own light?
No.
What planetary bodies create their own light?
Stars.
How do you get the value of the mass and speed of light?
The speed of light is roughly 300,000 kilometers per second. You'll have to get your own mass.
Why is the moon described as a mirror not a light source?
The Moon reflects the Sun's light, it has no energy of its own to create light.
What do you mean by Bioluminescence?
an animal or living being that can create its own 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.
Can fire have its own shadow?
Fire gives off its own light and will not have its own shadow, but the smoke from a fire can create a pretty big shadow.
What happens when a high mass star dies?
It will implode under its own incredible weight and create a blackhole.
Is this a correct definition If it cannot reflect light is it nonluminous. For instance fabric cannot reflect light but it does not emit its own light?
No, that is an incorrect definition. Luminous means creating its own light. Non-luminous just means not creating its own light. For instance the Moon is non-luminous. It *does* reflect light. It just does not create its own. Fabric also reflects light. It does not reflect it the same way a mirror does (mostly the light it reflects is scattered) but the fact that you can see the fabric even though it is not emitting light itself means it is reflecting light emitted from other objects. However, it is still non-luminous because it does not create its own light.
Is a star self-luminous?
Yes, starts create their own light. However, they do not last forever. Once they burn out all of the hydrogen used to create the light, they die.
How did gases create the Sun?
Gravity! Get ENOUGH gas, as light and tenuous as it is, and its own self-gravity will cause the gas to collapse in the center. if there's enough mass, it will get more and more dense, and eventually get hot enough to begin nuclear fusion.
Small bodies revolving around planets which do not produce light?
They're considered moons. If I'm mistaking, no moons create their own light. The Sun's rays reflect off of the "small revolving body" surface and create the light we see.
