You might want to head over to youtube and search for the 2013 Asimov debate. Its about 2 hours of discussion on what nothing is.
Bottom line - not much agreement.
I actually watched it last night. As I interpret it (beware) space can be deformed by gravity and therefore has structure - even if completely empty. Nothingness (absolute) wouldn't even transmit Gravity (or light). There was a lot of debate as to whether nothingness is subject to physical laws of any kind. Again no real conclusions.
