Shall give you some clue..you can see it everywhere, it has only one colour, you can even see it with your eyes closed.. get it??? its darkness.. or u can say BLACK.
why do i think it's infinite??? well there are alot of reasons which supports my answer..
- It is everywhere. as in if there is light there is dark but if there is no light there is still dark!!!
- Our universe is BLACK.. only lid up by Sunsssss similar as our own Sun. without those suns... we still get "black".. haha
- You can never escape dark/blackness.. ( if u can live without blinking then this reason is invalid)
- Ever heard of the Black Hole?? even light cannot exist there..
- it does not need a source, if it can exist without a source then there is no end to it??.. ( light needs a source such as fire or elec)
- err.. lazy type so many.. but u get my point..
So now, do you agree that the only thing that is infinite is Darkness/black??
you cannot escape it u cant even live in it.. one day.. darkness will consume everything..
