Reality is relativeThat's an interesting observation fam but let me ask you do you believe everything is real? and if not what method do you use to determine what is real and what is not.

+rep to anyone who breaks down the op article into about 4 or 5 sentences so us simpletons can better grasp this theory
One paragraph I think everyone who has seen this headline should read:
Neither of the model universes explored by the Japanese team resembles our own, Maldacena notes. The cosmos with a black hole has ten dimensions, with eight of them forming an eight-dimensional sphere. The lower-dimensional, gravity-free one has but a single dimension, and its menagerie of quantum particles resembles a group of idealized springs, or harmonic oscillators, attached to one another.
So... a proof-of-principle that a universe with gravity in many dimensions can be modelled by interactions in a universe without gravity in fewer dimensions. Well, great, I suppose: the holographic principle can be used to make calculations, but no predictions have been made about our actual known universe despite the first sentence saying:
A team of physicists has provided some of the clearest evidence yet that our Universe could be just one big projection.
This might be technically true, but looks to me like pure sensationalism.
First off:
Then, what does (roughly) means:
- Don't mistakenly associate the word hologram with the Matrix or a StarTrek holodeck. It's a mathematical representation of something inside something else. It's like a video playing on your screen: it's there, but it doesn't take place on your actual screen. It also hold more or different "dimensions" than your screen is (you're watching a 3d videorecording on a 2d screen).
- Dimensions are a though concept. It's not just about left right up down "and time being the fourth dimension" - it's a mathematical system that goes over the head of many. For now, consider them as "variables of a calculation", where the calculation is the system.
- Stringtheory is a (albeit debated) theoretic framework that explains all the different particles and behaviour.
- Strings are 1-dimensional objects.
- They run into a lot of problems explaining all the stuff happening in the universe, what happens in black holes (look up black hole entropy for example) and gravity and such.
- In order to explain part of the stuff happening they need 10 dimensions to make the math work.
- In order to explain a different part of the stuff happening and work with string theory, they have 1 dimension to make the math work
- They have managed to make the math between these two systems correspond to eachother. So they can now use the 10 dimensional calculations and place these "inside" the 1 dimensional calculations.
- This gets them a step closer to making the stringtheory as a whole "work".
- Concluding: it doesn't mean we are living a lie or that we're in some sort of fictional world that doesn't exist. It means they have managed to put a 10-dimensional framework inside a 1-dimensional framework, like putting a video on your screen.
A 2D object is a square. Cut it out of the paper. Rotate it so you only see the edge of the paper. That is a 1D representation of the square. It's not very interesting; however, if you rotate the paper back and forth (still keeping it flat - spin by sticking a pencil through it or something, then rotating the pencil), the line will grow and shrink (because the line that goes between diagonal corners is longer than the line which goes down the sides).
So given a constant speed of rotation, you could work out what shape you were looking at. If you add a different colour to each side, then it'd be a lot clearer, as the colours would come and go. Shine a light source and make the sides brighter if they are in the beam, and you get another way to tell how much of each side is showing - and the direction of rotation.
You could then tell the difference between a square, a triangle, an octogon, and so forth.
You'd have to have it moving (or move around it yourself), but that's no different to your 3D world. Is that a cube? I can only see a square. You have to see it from all sides to be sure there's not a different shape on one of the others.
If you want real fun with this, read "Flatland" which is a book about a 2D world inhabited by 2D objects. Then some 3D guy comes and lifts up one of the squares out of his 2D world. His perspective of that world is what you'd see if you got pulled out of our universe and into a 4D universe.
Just as the square can see the insides of all the Flatland houses, you'd see the insides of everyone else's house. If your eye and brain could interpret the images (and light could get up into the 4D universe).
There's a nice moment when a sphere passes through Flatland, and all the inhabitants see is a circle which mysteriously grows larger, then smaller, then fades away.
50% of the participants of this thread understood that when it was described as a hologram it wasn't meant as a projection.Usually when articles like this come out I try to go to the comments and see what the flaws are cause most times this shyt is just link-bait like every new "we cured cancer!" paper that comes out...and doesn't really mean what the headline says.
I'll just grab some of the most salient comments I saw from the reddit on this.
@Uncle Kingpin was right about the reference to the book he suggested in the HL post as being relevant...but all that other shyt about quantum entanglement being inherently present in cognition is just straight conjecture.

basically...they did some theoretical math where they removed the influence of gravity to try and make this SIMULATION try and reach the conclusions they had set out for themselves.
This is cool and all...but its not really getting where people think it is. The word "projection" is screwing people up.
or maybe you could learn to actually not waste your time saying things devoid of actual content.@Napoleon that's exactly your problem. You want everything black or white, numeric, proven and defined by substantiated-- whatever.
Spirituality in a simple definition is a state of being. Thoughts, emotions, feeling are all aspects thereof.
It is abstract concept that is not definable, only understood. Parallel to how I can spend here to years beyond explaining [murderous-hate] to you, and you will never grasp it's true [spirit] until your self is being enveloped by [murderous-hate].
Stop being so confrontational and just discuss with nikkas, we ain't trying to push and shove all the time
and you're in the other 50% that wanna bring in your spiritual bullshyt.50% of the participants of this thread understood that when it was described as a hologram it wasn't meant as a projection.
if its not tangible but a relative emotional concept then stop trying to make it more than what it is.Not even that, a lot of people are confused on the word "spiritual" because, for so long, it's been attached to the word "religion". But anything that affects you can be spiritual and people go through spiritual change all the time both religious and non-religious.
And yet none of them, including us, can see all of the dimensions and all the spectrums.
I never said it was tangible nor more than what it is and if I did, I didn't mean to. I actually stated it's the exact opposite of tangible if I'm not mistakenif its not tangible but a relative emotional concept then stop trying to make it more than what it is.
and you're the nikka who thinks that if we can't measure something it doesn't exist.and you're in the other 50% that wanna bring in your spiritual bullshyt.
Great. So its a result of perception as a result of neurological stimuli.
