Empty Set doesn't exist

If you cant sense it, then it doesnt exist.

You cant see emptiness, therefore emptiness doesnt exist.

>>1 but you can sense space? space can be empty, but there is still space... (ever noticed how the walls don't cave in, in an empty room? ^^)

so how many empty spaces does an empty set have?

btw wouldn't the definition of set be Two or more items? A set of one isn't much of a set, a set of none even less so...
