I climbed out and walked away thinking a two dimensional holographic universe was silly.
Humans often go wrong in our theorizing about the universe because of the way we experience time. Personally, I don't believe in time; time itself is an aspect of energy; the perception of time was a useful shortcut in the evolution of life. If you want to see how that might be, consider the odds of this: Every one of your ancestors from the beginning of life on earth managed to survive and reproduce. And here you are. Your time is now. (And hell no, I'm not being metaphysical here. I'm quite comfortable with "perception" as a physical process. A chemical process. A yeast cell can have a basic sort of perception.)
From the imaginary perspective of a photon there is no time. And then you've got Einstein's infamous equation E=mc2. That doesn't mean mass can be turned into energy, or vice versa, it means mass *is* energy and energy *is* mass.
With that mental model I see there's only one speed in the universe, and that is the speed of light. Everything else is an interference pattern written upon that light.
That's how you end up with a holographic universe. It's not two dimensions and then this funny third dimension time. It's three identical dimensions. If, mathematically, you lock one of these dimensions down and transform the entire 3D universe across the other two dimensions, then you are not seeing the entire picture.
