Who can say?

What happens if you wish for your wish not to come true?
If your wish is that it will not come true, what happens?
Does your wish come true, thus making your wish not come true? Or does your wish not happen, therefore allowing your wish to come true? Either way, your wish does not come true, and you end up disappointed and slightly confused as to why you wished that in the first place.
You probably shouldn't even try to wish that.
The universe might explode, or implode.
Speaking of...
Are we simultaneously exploding and imploding? Is that what holds us together, pressure inside and out? Is every object like this?
Ponder this, and weep for your sanity, as I do.
