Nothing

Posted on: January 16, 2012

Is there such thing as nothing ? I was taught at school that there is nothing in quantum physics (as well as it proves that nothing comes out of nothing). But is nothing in quantum physics same thing we understand as nothing by our intuition ? In quantum physics nothing is just sate of system, so to get nothing at least system has to exist. The good analogy can be found in Stephen Barr book which refers to bank account where someone can get 10usd, or 0usd (state of system is changing). But zero balance on bank account is not the same as not having bank account, right ?

In  quantum nothing (vacuum) where there is nothing but supposedly empty space there are constant quantum fluctuations with particles continually popping (so called pair or matter creation) into and out of existence.
