with respect to bertrand russell & raimon popper

is it possible to post nothing from Lorentz center in Leiden university which is in Leiden , Holland ?
is this question meaningful ?
is n`t that a sign of being nonsense ?
is it possible to deny one self ?
let`s make it more clear, is there exist the term "nothing" .
logically , the answers are no ,
but it is obvious that i did this !
