Semantics, look who's arguing semantics. Yes, pressure requires energy, I know, that is what arguing semantics is. And pressure has to have a barrier to contain the energy. You know energy really is mass, right? Particles exerting forces against other particles. There is a barrier of other particles to contain the energy of particles. There always has to be a barrier to keep in pressure. If that is not a law, then it is a law in my book, I will make it my own law. Mass is the container of energy. To have mass is to contain energy. It is somewhat related to my law of opposites. If one doesn't exist, there is no purpose for the other to exist. This is not thought experiments, this is well known knowledge which is collaborated. Vibration/movement=force=mass. Energy has to be contained. Even if it is contained in a seeming unforseeable barrier. Take nitroglycerin, for instance, it needs no pressurized container to reach the pressure it needs to explode because it explodes so fast, with such force, that the thinner air molecules around it contain it well enough to explode. We may see no barrier, or no container, but there is. It is air. Just as the universe is exploding so fast, we may not see or sense a container, but it's there, it contains the forces of the universe. And I will not stop replying until my theories can be rebuked by you or anyone else using known physics. I stand for the truth and won't let the truth be put down unless I feel I'm proved wrong, then I will put it down myself.
