The major feature of a hologram is that you can't destroy one part of it individually, all such an attempt does is degrade the entire hologram on a percentage basis. Sort of like an insurance company if you think about it.
Physical reality doesn't behave like that. Individual structures can in fact be destroyed.

Is the Universe a Hologram? Maybe the tiny part we can see is, the visible matter, about 4% of everything in the Universe. The vast majority of the stuff in the Universe isn't stuff, it's either dark matter (about 22%) or dark energy (74%).
You guys are misunderstanding what they mean by "hologram". They are not referring to the shiny images you might find on a credit card. They only mean that we live in a flat two-dimensional universe that maintains the illusion of having three dimensions.
as a 2D world, wed always face the same way.
Maybe we do. We don't really perceive our 2-D existence. We only perceive the illusion of a 3-D reality.
But maybe in those 2-D processes behind the 3-D illusion, we are not coherent organisms that could be said to be facing anything at all.
I like theories that help us understand some of the big questions in cosmology, like "what exactly is Dark Energy", and "what exactly is Dark Matter made up of"?
I wish people would stop naming stuff "dark something".
"Dark matter" made a bit of sense as a label. "Dark energy", not so much. Subsequent attempts at "dark something" haven't really taken off (thankfully), but now it seems like every time someone identifies a new issue in cosmology, they try to name it "dark something".
Unfortunately, String Theory and Hologram Universes don't really do much more than make the math look more neat and tidy.
"Having the math work well" is a very important part of a theory.
