Up or down several dozen orders of magnitude. Time and space exist for the cells in our bodies, and for mountains, moons and most stars. Time and space only break down substantially for things smaller than molicules or large enough to twist spacetime back in itself (black holes). A mouse is no further away from the moon than a dog or elephant.
Time and space does not exist for a mountain. Time and space are first and foremost concepts (ideas, opinions, "facts") Have you tried asking a mountain whether it ascribes the state "exist" to the concepts of time and space? It is true that time and space exists for humans thinking about the mountain however.
> Time and space does not exist for a mountain.
Time exists for the mountain. The mountain moves through time and is effected by time. The mountain is incapable of perceiving time. Neither can bacteria perceive dimensions, but they are still controlled by them.

Perhaps a bit of a tangent, but another way I have always perceived relative distances measurements is with the following analogy: You are awake, walking around a basketball gymnasium, it's 100x100x100ft. A nice, large room. All other details preserved as well. Surely, our little brains can't contain a 100x100x100ft gymnasium; our little heads would explode trying to fit something so large into it. Yet, when we dream…
There is just so much more to discuss on this subject, including the intricacies of how all events are stored in the brain with cross-connections/relations to other events. Basically, every memory-dimension (time, temperature, happiness, anger, feelings) are all stored in nice gradients with connections to other memories. i.e. The only thing making you think that some past event, yields to some "next" event, is a ser…
This reminds me of Kurzweil's explanation of dreaming, as offered in "How to create a mind" book. He claims that during dreaming we experience random, uncoordinated activation of synaptic links and some small portion is recorded in memories. It is only when we recall our dreams that we infuse meaning into them, building a structured and sequential narrative around random stimulus so that our mind can make sense of these memories.

Freedom of will is completely compatible with fully deterministic world. Just consider that there are many fully deterministic worlds but the one one perceives themselves in depends on freedom of choice.
Who chooses the world to perceive? How is the choice made?
That are implementation details. The point is that apparent determinism of the physical world has no implications for free will considerations and cannot be used as an argument against it.

#175Possibly dumb question, but I know my niece is going to ask me about this, and I'd like to be able to give her a solid response: does this mean that most distances within our universe are illusory? If not, why not? To expand on that thought a little bit, with a hologram, the projected object is an illusion, and can be made to appear to move at arbitrary speed by e.g. rotating the projection apparatus. On a larger sca…
> If this theory models the universe as a 3D (or more) projection from a 2D surface Further, would such a projection suggest a possible mechanism for entangled particles to interact at distance (e.g. the particles are separated in 3D-space, but are co-located in 2D-space)?
No. Entangled particles don't interact at a distance.

Could be a dimensional thing too, what if you're like an exhibit in someone's living room like a hologram and you just live your life for someone's amusement. You'd never know but can you prove that it's happening?
Reminds me of The Thirteenth Floor .
Oh I like that movie, man haven't seen that in a while. I don't know, what makes something "real" or "more genuine"? I heard this podcast that mentioned this same concept regarding your brain acting like a computer perceiving sound as binary input through the little hairs in your ears... I don't know. What's real is this fear I feel from debt collectors haha.

This is falsified by people who have had interactions with waking people while asleep, conducting conversations and interactions, even if nonsensical. So there is online processing during dreams, not just a "ghost" memory left behind afterwards.

Calling it "holographic" was probably a bad idea because it generally makes people think about Star Trek. You're not quite as far off when you think about lasers shining through a photograph of an interference pattern in order to reproduce a light field that a human observer will perceive as a 3D object.
If you look a that photograph in normal light it just looks like a lot of black and white lines and blotches smeared out over the surface instead of the original object that was photographed. In a holographic model of the laws of physics, the entire content of the universe is encoded somehow onto a 2D surface. If you could somehow see that surface, it would not be obvious that it encoded anything in particular. Where the analogy falls down is that there is no laser that projects a 3D image from this surface. There's just a set of 2D laws operating on the 2D information. To anyone on the "inside", as it were, the universe still appears to be fully 3D with 3D laws of physics.

> there is substantial evidence supporting a holographic explanation of the universe—in fact, as much as there is for the traditional explanation of these irregularities using the theory of cosmic inflation.
This is a bit misleading, especially the phrase "substantial evidence". I bet that the authors of the paper would not have used this phrasing. From the paper:
> We emphasise that the application of holography to cosmology is conjectural, the theoretical validity of such dualities is still open and different authors approach the topic in different ways.
Essentially, their paper shows that a holographic model cannot be ruled out simply by comparing the predictions it makes for the CMB to observation. It also gives some intuition for why a holographic model might make sense - at sufficiently early times in the Universe quantum and gravitational effects begin to coincide, and in other contexts people have modeled quantum gravity using "a quantum field theory with no gravity in one dimension less". The paper finds, however, that there is no empirical case to be made for discarding the standard model of inflation:
> We see that the difference between evidence for [the standard model] and HC predictions is insignifcant, with marginal preference for HC, depending on the choice of priors.
Re: Study reveals substantial evidence of holographic universe
#180I've recently been thinking on how our human definition of intelligence might relate to holographic principles, particularly in regards to information theory. We are small creatures, but our networks -- our brains and societies -- represent the most complex information-encoding geometries we've yet seen in the universe. And I see the way that our curiosity reaches upward in scale, documenting the far corners and fold…
If you haven't read it already, I suspect you would greatly enjoy "The Beginning of Infinity" by David Deutsch (a quantum computation-focused physicist). It's a surprisingly optimistic take humanity's nearly-unlimited potential (or so he posits) for discovery and creation, and a great companion for any armchair philosophizer.
I suspect that many of the replies to this comment who cynically cite variations of "the principle of mediocrity" would also do well to read it.
He makes the point that the single coldest place in the known universe is not anywhere in the depths of space (which is gets down to about 3 kelvin), it's in a lab designed by humans and used for quantum mechanics research (200 nano kelvin).
Our capacity for information gathering and creativity has allowed us to create physical realities that cannot otherwise exist outside the influence of intelligent beings. Incredible to think about.
