theory's on black matter?

Robin Mulholland your idea is not a theory, and it is obviously false.

A scientific theory is a well-substantiated explanation of some aspect of the natural world that is acquired through the scientific method and repeatedly tested and confirmed through observation and experimentation. What you are calling a theory is really just a conjecture that you made up. Even for your idea to be a scientific hypothesis, the scientific method requires that you can actually test to see if it is false or not. Your Idea cannot be tested - so it is pretty much useless.

Light is not "consumed" -- consider things like light bulbs. They produce light when they are connected to electricity and stop when disconnected, but they are not consumed, they stop working only if the tiny filament inside them is broken - but it is not consumed when light is emitted.

You are obviously confused or misinformed about the nature of light. Light does not burn or otherwise combust matter when it passes through it, this is observable if you examine windows and glass which allow light to pass through them.

If you want to understand physics why don't you try reading a book on the subject or visit the sites in the links below;

It is a theory and if you do not know light is absorbed and consumes then maybe you need to look up what happens to a light wave inspace it never stops unless absorbed .so in space there is no matter to absorb the light.d.Which black matter expands so it has to be the elements that have been burnt up like the ash of a fire you can no longer light them because they have been consumed .You need to study light waves if you think they are not absorbed and they consume energy that is why things fade and decompose when exposed to light.it was created by fire.so,a light wave like fire consumse or is absorbed by matter. So when black matter has be consumed to the point that it no longer contains enough matter to absorb light .It is simply a burnt out element and since space black matter expands. then something has to be producing it and since in space all tha is occuring is the consumption of matter then what issblack matterLets hear you theory.sorry trying to speak english I said like fire

Compost? Ash? You gave exactly no concept of what you are saying.
