Eh
Sorry, but the budding physicist in me had to point out a few flaws and/or suggestions in this theory.
One: a hologram CANNOT be projected through a solid, opaque object.
This would mean that either we are not holograms at all, or everything, not just us, is a hologram. The walls, the computers, all of it.
Another thing... light can't radiate light or heat, and I think I remember from one of your posts something about heat. Light IS radiation. Electromagnetic radiation, in fact, along with radio waves and stuff like that. Heat isn't even radiation; the 'sense' of heat is actually just the transfer of thermal energy, which is in fact just kinetic energy. The temperature of an object is really just the amount at which its atoms vibrate, and this vibration can only be transfered to another atom through touch. I have a bunch more things to say about this 'theory', but instead I'll try and add something to it.
Now. In my opinion, the only way for this theory to really and truly work is if the calculations and stuff don't happen inside 'us'. The thought processes and the collision and all that, would not be able to happen inside what we think to be ourselves. There would have to be one massive central computer, or mainframe, or whatever the hell you want to call it, that processes it all in numbers and such, and keeps it running. It would then have to project this as one gigantic, constantly-moving hologram. The holographic people in this world would have no need of the hologram itself - all their life is calculated and processed through the central computer. What they see, is what the computer is saying they're seeing. What they hear is the same. Which leads to my final point, question, or whatever you want to call it; why? Why would there be this gigantic computer set the task of projecting this useless holographic universe? Would it have been built by some monstrously intelligent alien race? Or maybe, it was built by humans far advanced, who wish to play back certain scenes of history, interact with them, and change them? We might be some gigantic video game, really! And you'll notice that almost all these 'why' questions are similar to the why questions of a different topic. This theory, in effect, is a god theory, albeit flawed and presented wrong. Who knows, it might turn into some religion? I mean, who can possibly disprove such a monstrously outlandish claim as that which has been described above?
