What do you think about the holographic universe theory?

In Physics, the question whether reality is a "Phantasm" does not have any meaning. Physics is taking data, and putting it into a formal framework that has descriptive and predictive power. Keeping that in mind, one needs also to understand the two issues here, neither of which are as new as this article would make them appear. One is the violation of Einstein's locality, which was inferred from the famous EPR paper, then shown by Bell's Theorem, and experimentally verified since then. This is called entanglement. It is completely non-intuitive, but works mathematically. No physicist pretends that there is any signal going between the entangled particles, since Einstein's tenet that no communication travels faster than the speed of light still holds good. The second issue here is the holographic theory, that says that if there is a theory describing an n-dimensional space which has a border, then there is a theory that describes the same things in the n-1 dimensions of the border. This works pretty well for black holes, but the theory is still a little uncertain about other things, such as the observable universe. But it seems to work for a number of current theories. This does not mean that our space is 2-dimensional rather than 3-dimensional, it just means that you can describe it in either system. Now, here comes the jump. Using the holographic principle to explain entanglement is a very tempting undertaking, and is worth the very serious research going on in that direction. However, there is a lot of hairy mathematics involved, and this connection has not yet been finalized. Until it is, Bohm's ideas remain speculation.
