They might be giving off light so bright we cant even see it. Just a thought. OH and is it true that light is electromagnetic fields and if so how far can one electro magnetic field go for if there is nothing in its way to stop it? Basicaly what im asking is one ray of light enoth to fill a universe full of energy?

Mine is DEFINITELY a BLACK HOLE.

Actually black holes are a combination of things:
The Singularity: The singularity is an object sso dense that it warps spacetime around it and creates a gravity field so massiveThat escape velocity is greater than the speed of light (ALL forms of electromagnetic radiation obey the same speed of light).
The Event Horizon: The distance form the singularity where the escape velocity is equal to the speed of light. Just above the event horizon you often find jets of X-rays which are given off by the material which is about to fall into the singularity.
The Accretion Disk: the only part of the black hole which can be observed, here is where the material which has come under the gravitational influence of the black hole gathers. It's typically called a disk because it spins around the black hole and flattens out into a disk.
Light is electromagnetic radiation, a "field" is more a mathematical way of describing the properties of the radiation. Any radiation can travel forever if nothing gets in it's way. Theoretically the amount of light produced in the universe would illuminate the entire thing IF there weren't a LOT of dust, gas and other matter in the way. But One ray of light wouldn't be sufficient because the current size of the universe is much greater than the energy of even the highest frequency of electromagnetic radiation (gamma rays). The ammount of energy which reaches a location is 1/D*D (D=distance form the source). 1/12billion*12billion is immeasurably small.

ok...yea, it would be great if black holes give off light, but it can't because of the infinite gravity in it. the idea is if you somehow got into a black hole, your head will tear off because the gravity difference is so great between your head and your neck. but no one can test it...light is not electromagnitic field. light is consists of photons that behaves as waves, electroganetic field is an entirely different topic.Photons are really really really light and it's in constant motion. in theory, it won't stop if nothing stops it. the behavior of photon is closely tied to quantum mechanics. energy comes in different form, the universe is full of energy in a way. the question isn't quite valid...i am sorry i don't know how to answer that.....

The definition of a black hole is a point in space where gravity is so strong that even light does not escape. Therefore your premise is wrong by definition.

it's not a light thing as much as it's a gravity thing. light can't escape the pull of the gravity in a black hole, so there is no light coming from it. i don't really know about your last question, but what does any of this have to do with CATS??

A ray of light won't do that becuse light is effected by gravity it ends up in orbit somewere.

how is that a cat question? you lost your cat in a black hole and you hope he went to the light?

My forecast is you're going to be a physics professor.
