Universe from Nothing

Abstract

The book "Universe from Nothing: Why There Is Something Rather than Nothing" by Lawrence Krauss has stimulated a lot of aggressive debate between philosophers and physicists and gained mediate attention. The basic criticism of philosophers is directed to the identification of "nothing" as vacuum state and it is easy to agree with the criticism. In this essay the purpose is not to consider this issue but go one level deeper and ask what existence could mean - an issue  not often discussed in physics circles dominated by materialistic philosophy.
