Simulations back up theory that Universe is a hologram
1) What the heck do they mean by a hologram? The analogy here baffles me. Is this just a layman's analogy, or does this actually mean something scientific?<p>2) Anybody have any suggestions on a high-quality layman's explanation? I finished reading Feynman's QED the other week, and loved it, and was wondering what the closest might be for string theory.
