It is well-known and discovered by both Euler and that sane madman Ramanujan that if you were to add up all the numbers: 1+2+3+4+5+6...etc then they would add up to -1/12:

I told him that the sum of an infinite number of terms in the series 1 + 2 + 3 + 4 + ... = -1/12 under my theory. If I tell you this you will at once point out to me the lunatic asylum as my goal.- Srinivasa Ramanujan, second letter to G. H. Hardy
Now, If we let E stand for Everything, we can see that then E=-1/12: 1=-12E
-12 (E+E+E...)=E
-12E (1+1+1..)=E
-12 (1+1+1..)=1
(1+1+1..)=-1/12=E
Now subtract this from the original equation and you get:
(0+1+2+3...)=0
or,
E=0
ergo, Everything is Nothing.
