i am doing a astronomy class project if light ends ... and i think it does , no one really knows what is ur opinion?

how could it end? do you mean dispersion or some other form of diffraction? I could see it appearing to end when traveling through cosmic dust or other debris, but not otherwise. Theoretically possible, but not probable.
GENE:
Actually it doesn't even end there. Our eyes reflect a great deal of light...hence, the color of our eyes. SO that light that is reflected is not ended.
REMEBER PEOPLE:
Light acts as a wave as well as a particle....It CANNOT just be absorbed. It is also reflected, refracted, and diffused when it is "absorbed". EVERYONE is saying that light is absorbed by our eyes and our cameras and plants and everything else....If ALL light was absorbed by something, we couldnt see anything, there would be no color, because the only way we see these objects is because THEY reflect light as well...

You could say that when light enters a black hole, time ceases to exist and all matter becomes a singularity(infinitely massive, infinitely small point).
But you'll probably have to look into Stephen Hawkings theories about that if you are unfamiliar with black holes.
Other than that, you could say that light ends when it is absorbed by a object. For example, light has a beginning. When an electron drops an energy level, a photon is released(light emitted). An on the other hand, when an object absorbs a photon, it excites an electron up an energy level, which most likely will heat the object. So yea, light can end by transferring its energy to an object.

With my basic understanding of science and astronomy (am I smarter than a 5th grader?) I do know that nothing ever ends, in those exact terms. Things only change form and become other energies. Light is energy so when our eyes don't see it anymore that only means that it has been absorbed into other masses or has been transformed into another form of energy. Not being too technical I would say no it doesn't end.

Can you give more detail by what you mean "does light end?"
Light is an electromagnetic form of energy. It is emitted by all kinds of processes where energy is radiated. The same matter that emits lightwaves can also absorb lightwaves. A specific process that emits a photon of a particular wavelength (e.g., an electron 'dropping' from one orbit to another closer to the nucleus) will also absorb a photon of the same wavelength (the electron moves 'back up' to its original orbit).
So, as long as there exists 'something' to emit light, then there will exist (the same) something to absorb light.

Another interesting viewpoint is this: Because the photon travels at the speed of light (while it is in a vacuum), then all distances are zero for that photon. Therefore, as far as the photon is concerned, there is no time.

Yes, we DO know the answer to that. Although you weren't very specific in asking it.
By 'end', I assume you mean stopped, absorbed. Yes, light is absorbed - by our eyes so we can see, by our cameras so we can take pictures, by plants to make energy through photosynthesis, by anything else to heat it.
If you mean light that is never absorbed, then no. It doesn't end, it just goes on forever. It doesn't lose energy or momentum if it never encounters anything, and it can be redshifted to lower wavelegths depending on how you look at it, but it won't be gone.

A photon (light) travels continuously until it interacts with matter. If there is no matter, the photon continues without end.
Light does not end.

The photons of light can be absorbed, refracted or bent but they do not end

you need to in all hazard take down your mild approximately by potential of January 10, you could think of thats somewhat previous due yet some each and every person is extremely busy and dont take them down till the tip of the subsequent month.(i could of exaggerated in elementary terms somewhat)

It ends when it gets absorbed by something like our eyes or a shirt or a planet

well we don,t know that yet ? but maybe some day .as it is now light years go on and on ,on,on,on,on far as we can see or go, so keep looking up and look in to the light years
