Can something become nothing? In an absolute sense. It seems impossible intuitively speaking, but I have hard time figuring out a logically strict arguments. Thanks!

Merriam-Webster defines the relevant senses of the verb "become" as "come into existence"; "come to be"; and "undergo change or development." Given that definition, how about this argument?

(1) Necessarily, whatever comes into existence, comes to be, or undergoes (qualitative) change or development exists at the end of the process of coming into existence, coming to be, or undergoing (qualitative) change or development.
(2) Necessarily, whatever exists is not nothing.
(3) Therefore: It is impossible for something to become nothing.

If that argument is sound, then it's only in a figurative sense (rather than a literal sense) that something becomes nothing when it goes out of existence.
