Very interesting speculation, Slingshot. It seems you're saying that an open system is one in which the most fundamental physical law of the universe has no effect -- that would be the first law of thermodynamics. It is difficult to imagine what such a system would "look like." The first law has been interpreted as representing the basic symmetry of the Universe, and the second law, what facilitates the "symmetry breaking" necessary for things to come into existence. The second law is also that which gives us "the arrow of time": existence, unlike many physical processes, is not reversible in time....
You wrote that an open system would be one in which more energy can come out of the system than was put into it. Which just reminds me: I wonder where virtual particles "come from."
Anyhoot, your speculation or conjecture raises huge issues Slingshot! Will think about it some more.
Thanks so much for writing!
Conservation laws are obeyed whether or not systems are open or closed. An open system can exchange matter and energy with the surroundings, but the amount of matter and energy entering from the surroundings is exactly equal to the amount leaving.
I tried to reply and had a message come up that said I needed to correct a statement. I don't know how to correct it.
Dark energy/matter(DEM).?.. Could be DEM is what space is.. and even more mixed into "Light energy/matter(LEM)".. Is it possible that DEM is all around us.. and is where electricity comes from and goes back to(maybe).?.. Metaphorically LEM is the painting we can see/sense as humans, DEM is the other side of the painting.. i.e. The painting(LEM) appearing to one set of "dimensions" but when viewed front and back(DEM) (so to say) other "dimensions" are apparent/included..
LEM = being everything we know about and are aware of.. DEM = the reciprocal base of LEM.. both being the whole.. The whole of what energy/matter is... a closed system... LEM being an open system and DEM being an open system too.. but both together are closed..
Did I say anything.?. ;^)
