Hi.. If anyone could answer a quick question.
I have a very basic understanding of black holes which goes as follows. A massive star collapses in on itself creating a black hole. This black hole is so powerful that its gravity sucks everything, all matter and even light into its centre past its event horizon and onto a singularity.
Now what i dont understand is that if a black hole sucks everything into it does this mean that the universe being eaten by these black holes, so that eventually, all matter in the entire universe is eaten, leaving nothing?
Or is it that a black hole can only eat a certain amount and has a limited lifespan... if this is the case, then what happens to the black hole and all the matter it has eaten?
Or is it the case that the Universe is expanding quicker than the black holes can eat it? So there is always more universe being created to counter the universe being eaten?
As you can see, my understanding of these things is very limited... but any help would be appreciated!!
