We know how things can be created from quantum mechanics, but can nothing be created as well?
How much nothing would you like? (Sorry...but this looks like word salad)
Meaning VACUUM or VOID. What mean nothing?
Right. It all depends on what one defines as "nothing"
If a vacuum will do, then yes, there are techniques to create the conditions for very high vacuums.
But I don't think that's what your questioning.
