Regarding the 3 Laws of Thermodynamics?
Can these laws be broken? Or to be more precise, is there evidence that forces can fall outside the laws of thermodynamics causing the creation of energy or matter? What are the percentages that energy and/or matter can be "created" or constructed from "nothing*"?
Can entropy be realistically reversed in a perfect vacuum? Can energy or matter exist with zero friction?
(* - nothing being defined as of no matter or no energy)
Blessings

Yes, and it is a bit embarrassing to scientists. According to Newton, the galaxies at the edge of the universe should be slowing down. Instead, they are speeding up. In order to explain this, physicists had to come up with a new force, called "Dark Force." If you ask any of them to explain Dark Force, they begin to stammer and try to change the subject. And, if you really want to have some fun, ask them to explain "Dark Matter."

As far as we can experimentally determine, these laws hold. The first two laws deal with energy and conservation of energy while the third deals with the notion of entropy or randomness. Let's address entropy first.
It is possible to reverse entropy in a local isolated system if you only look at the system and not the system plus its environment. For instance, you and I shoot a game of pool. You break and scatter the balls around the table but unfortunatley for you, noone of them go into the pocket. You did work on the system - the pack of balls - which increased their disorder. Now you and I decide to let you have a "do-over" so we re-rack the balls, again doing work, and they are now in a more ordered state. So you'd argue we decrease the entropy of the pool balls. But in doing the work to re-rack the balls, our bodies inefficiently used energy resulting in waste heat that was transported into the surrounding environment through convection and radiation, thus entropy in the environment increases. If I eliminate the atmosphere, we'd still dump the waste heat via radiation. So having a vacuum, doesn't really help. Of course if the universe were completley empty excpet for the pool balls, there would be nothing to dump the waste heat to but then we d=wouldn't be present to provide energy to order the pool balls. Entropy is a system plus environment concept so it realistically can't be reduced.
Friction is a reuslt of matter interacting with other matter via electromagnetic fields. If you don't have one chunk of matter rubbing against another chunk - no friction - both chunks still exist.

No.
The laws of thermodynamics have seemed to be the most stable if not the best understood for a long time. The 2nd law can be violated locally, temporarily but on the large scale, it holds totally.
Matter can exist with zero friction - look up superfluidity in Helium but it still doesn't violate the laws of physics.
Aha! I was looking for this quote:
"The law that entropy always increases holds, I think, the supreme position among the laws of Nature. If someone points out to you that your pet theory of the universe is in disagreement with Maxwell's equations — then so much the worse for Maxwell's equations. If it is found to be contradicted by observation — well, these experimentalists do bungle things sometimes. But if your theory is found to be against the second law of thermodynamics I can give you no hope; there is nothing for it but to collapse in deepest humiliation." — Sir Arthur Stanley Eddington, The Nature of the Physical World (1927)

check out the video http://www.magniwork.com/?hop=tomeraff
more energy out then in....this should not be possible...and maybe its not...but this video is interesting nonetheless
