Consider for a moment the classic question "Why is there something rather than nothing?"
My favorite answer is a terribly funny statement by a stand up comedian in Hebrew: "eem ein ein, az yesh yesh!" which is an impossible to translate word play of meanings, that means something like "existence exists since nothing does not"
From that point of view, existence is infinite and inevitable, and nothingness is just a concept which cannot be.
I think that it is because of our own mortality, that we tend to intuitively picture reality as a finite speck of existence in an infinite sea of nothingness.
Rather, it is us who are a finite interval of phenomenal existence, and as a consequence it is quite surprising that we exist at all.
Indeed, possibly the only example of nothing that we can imagine is that eternal lack of consciousness which is death.
But then I ask, if nothing is the end of consciousness, then in what sense does anything exist once we die?
If this question ain't too silly, an answer with pointers and references will be appreciated; and to save you time, I would add that I don't believe the world is an illusion, nor that I am the only consciousness around.
EDIT - what a crop, one SPAM answer, and a comment suggesting this question belongs in Reddit's stoner-philosophy page.
Luckily I found a Nobel Prize winner to (sort of) back me up; in a paper called Two Kinds of Realities, Eugene Wigner wrote:
one would expect that my consciousness, the only absolute reality, should be permanent. It should have existed always and remain in existence forever. Again, this is clearly not so. On the contrary, there are realities of the second kind of which we think as permanent - electric charges, heavy particles. Surely the permanence of these objects after my death is meaningless
and:
my consciousness would dissolve into nothing some day. Then, there will be no absolute reality-and indeed there will be nothing
