This is an interesting linguistic deviation, as the definition of nothing in the English language refers to a universal negation, but it seems that Krauss’s ‘nothing’ is a label for something. Although his research claims that ‘nothing’ is the absence of time, space and particles, he misleads the untrained reader and fails to confirm (explicitly) that there is still some physical stuff. Even if, as Krauss claims, there is no matter, there must be physical fields. This is because it is impossible to have a region where there are no fields because gravity cannot be blocked.
