I'm reading J. Richard Gott's book, The Cosmic Web. Fascinating stuff. He's not a bad lecturer either. He specializes in Dark Energy and what it might mean about the fate of the universe. I'm with him on the Equation of State being greater than -1, which would indicate that the universe will end in a series of Big Crunch singularities. But like him, I am open to other possibilities, such as w being -1 or less, in which case the universe would continually be recycled in bubble universes, or end with a Big Rip (though the idea that all matter in the universe could rip apart is disturbing).
It's funny, I hadn't even known about these Equations of State until reading his book. Yet two of my theories generally describe two of the equations. If w=-1 it describes the Black Hole Hyperspace (my last post). If w > -1 it describes the Multiverse Manifold Theory. Keep in mind that I wasn't as familiar with Dark Energy or the Cosmological Constant when writing these. A critical element absent from these posts is the Cosmological Constant: a measure of the ratio between pressure and density that permeates all of vacuum space. In the Black Hole Hyperspace, the ratio is -1 (negative because we are describing the repelling nature of Dark Energy), and in the MMT Big Crunch scenario it is greater than -1.
Something else I stumbled upon is Quintessence: a proposed fifth fundamental force of physics. It states the value of w changes over time, and is therefore a force of its own, since it has nothing to do with gravity. Even if the Cosmological Constant is changing- in which case we should refer to it as the “Cosmological Variable”- we wouldn't be able to measure it for a very long time. But we are inching closer to pegging the value of w. Right now, the results suggest it's in the range of -.95 to -1, with increasing accuracy the closer it gets to -1.
