I understand the principle of holograms. I understand holographic technology as we have developed it. But to apply them to the universe as a whole sounds far fetched. Am I understanding it correctly? A projected 3 dimensional image? onto what? Or is it a 2 dimensional image that gives the illusion of 3d like those things you tilt from side to side? It sounds like a movie to me. The light from the projector encodes the data of the movie onto the screen and the screen acts like the event horizon "boundary" they talk about.
I'm a literalist mostly. This is what attracted me to the Electric theory. Its grounded in reality and so far can be backed up with experiment.
When I read about this holographic idea the first thing to come to mind is what is the information? Where is it coming from? Is it a projection? What is it being projected onto, our eyes?
To me reality is real. It is physical and I can touch and interact with it. Ideas like this destroy that reality and suggest its all fake which to me starts to delve into philosophy and not science. Its like the question of if a tree falls and no one is around to hear it does it make a sound? I say yes. Why? Because that is how it works. Because to say it does not suggests there is some entity or conscious in the world we live in that will detect if another living being is around and then generate an appropriate sound, like a computer program. This theory seems to suggest that we are living in a computer program. They use terms like bits and pixels to describe parts of the theory.
From the wikipedia article
The holographic principle states that the entropy of ordinary mass (not just black holes) is also proportional to surface area and not volume; that volume itself is illusory and the universe is really a hologram which is isomorphic to the information "inscribed" on the surface of its boundary [6].
This hologram "inscribes" information on the surface/boundary of the universe, I assume hes talking about. Would this not break one of the laws of physics that what was it...energy or matter... cannot be created or destroyed? The way I perceive reality is that its always changing. Each day is new. How does this 'hologram' know whats new and whats not in order to create these new states (days)? Each new state, if understand using their terminology, is new information, and thus new energy. Am I reading this correctly? I think I have it wrong.
What is the surface of its boundary? The edge of the universe?
If this hologram finally does reach the end of the universe does that mean we'll finally be able to see what the edge of the universe looks like when the light finally comes to us in God knows how many years from now? It would have to bounce back in order to keep the hologram real and so we can perceive it.
To put it basically, how I understand this theory, if the universe is a hologram, then so must everything in it be. Then that means the food I ate earlier wasn't real. So where did the information come from for that food? How was it projected into space right where I placed it and manipulated it?
Oi, no wonder people never bother to question any of this. I'm sure no one aside from the people who created all this even knows what it all means.
But the holographic principle and the fractal principle are in operation from small to universal.
So if you can understand that, then you get the holographic pricture.
Could you explain that? How would it relate to the physical world we live and interact in?
The article I linked is all based on black holes, string theory and maths etc.
