Our Universe:
Posted on 01/29/2018 10:20:15 AM PST by Gamecock
A team of physicists has provided some of the clearest evidence yet that our Universe could be just one big projection.
In 1997, theoretical physicist Juan Maldacena proposed1 that an audacious model of the Universe in which gravity arises from infinitesimally thin, vibrating strings could be reinterpreted in terms of well-established physics. The mathematically intricate world of strings, which exist in nine dimensions of space plus one of time, would be merely a hologram: the real action would play out in a simpler, flatter cosmos where there is no gravity.
Maldacena's idea thrilled physicists because it offered a way to put the popular but still unproven theory of strings on solid footing — and because it solved apparent inconsistencies between quantum physics and Einstein's theory of gravity. It provided physicists with a mathematical Rosetta stone, a 'duality', that allowed them to translate back and forth between the two languages, and solve problems in one model that seemed intractable in the other and vice versa (see

Kind of like Plato’s reality is a projection on cave wall theory.
Physical Sciences will one day prove that the Universe is a created thing!? Ha Hah
Why come?
Why come you got no tattoo?
Our Universe:
Insanity masquerading as science. Not worth even discussing. Someone wants a few minutes of fame.
Well, nuclear power (and nuclear weapons) had their origins in a bunch of esoteric equations at one point, too.
One possible outcome of explaining gravity and a string universe is coming up with unlimited energy or faster than light travel...
Or it could be a dead end, meaning nothing like the fruitless search for a “Northwest Passage” in the 1600’s. Still need to explore and try to push physics... The old adage is “today’s theory, tomorrow’s engineering project.”
Nothing in there saying that God is not the maker of the projection, sir.
Everything is a dream of a superior being? OK, that’s Buddhist and Hindu theology ...
If it’s a hologram then nobody needs money. Send it all to me.
Put these eggheads in an orbital vehicle, get them up to speed and then have them dive their space ship into the Earth. Then ask them how they liked the hologram of Earth.
"Can I buy some pot from you?"
Science fiction writer Phillip K. Dick is the first to propose this theory. Unfotunately, Phillip had a lot of mental problems.
Go way. Batin’.

By this logic, any arbitrary set of mathematical equations is worth pursuing since it might end up producing nuclear power.
Those of us who can actually do the math understand that the number of potential equations is infinite, and that any one of them may yield fruitful results is infinitely small.
The thing about those theories that amount to something... they all have physical ties to reality. Not one was a purely mathematic construct without any such tie, the way string theory is. There is not a single thing in nature that can be shown to behave according to string theory or according to any set of rules like it.
Hmmm. The heart bypass surgery I had a month ago felt real. Makes me have serious doubts about the hologram theory
I am a big fan of PKD—it is totally amazing that he wrote “Time Out of Joint” back in 1959—way ahead of his time.
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.Observations of the real universe don't support the hologram model either.Nevertheless, says Maldacena, the numerical proof that these two seemingly disparate worlds are actually identical gives hope that the gravitational properties of our Universe can one day be explained by a simpler cosmos purely in terms of quantum theory.
