What do you think lies beyond the universe? What is "nothing" but a different "nothing" than the vacuum of space? And why is this nothing attracting space into it?
Does this nothing adhere to thermodynamics? Isn't the pure exsistence of the something expanding into the nothing kinda not thermodynamics like?
Interesting questions! :)
To start, there is nothing such as "attractions", a term which is used within physics only in an informal manner. All forces, even field forces, are "pushing". That's exactly the way "suction" works with air vacuums for example. They don't exert "suction", but push material with their blades to another place, so to generate a void that the atmosphere itself fills due to it's own pressure (entropy!). This is no different from the forces you can exert yourself: think about it, you can only push things, never "attract" them.
So, in your words, "nothing can't attract nothing", which holds true regardless of the many interpretations of the words.
Absolutely everything, even nothing, adheres to the fundamental laws of thermodynamics, an absolute power of our knowledge that never stops to amaze me, which secretly relies in the fact that the laws of thermodynamics can't be defined in an absolute form but are always interpreted for every specific context.
