Is nothing something?

Martin Heidegger claimed that the most fundamental question of philosophy was why is there something rather than nothing.  But perhaps nothing is something too.  Nothing has properties: length, width, depth, duration, permeability, permittivity, etc. and these properties can be measured by our senses or by instruments.  If one then asks why a particular thing has the properties that it has the answer may be that we define the properties we define exactly so as to be able to distinguish things, one from the other.  i.e., to categorize and organize, to describe. (And there is no need for everyone to define the same properties and the same categories. Reality can have alternate descriptions. And we are all free to create categories like unicorns that aren't really observed.) Again, "nothing" would be just another "something."
