Imho, they should concentrate on the basics for now, say....lets start with the electron, what is it in reality made of?
What you don't know can't hurt them.

Real as in not just a mental conceptualization, be it in words or mathematics, but an unveiling of the whatever it is that the concept 'electron' stands for.freemason9 wrote:Let's start with what "in reality" means, though.Ben D wrote:Imho, they should concentrate on the basics for now, say....lets start with the electron, what is it in reality made of?
Firstly, the question wasn't what an electron stood for, but what is the reality represented by the concept 'electron'?justdrew wrote:electrons don't stand for anything anymore, all they do is spin.
anyway, its just a few quarks init?
well, you can make them out of photons, if the photons have enough energy. so I guess the same thing "light" is made of. it may even be they're all little complex standing waves in the space manifold. so what's that? It's axiomatic. might as well ask what a number is made out ofBen D wrote:Firstly, the question wasn't what an electron stood for, but what is the reality represented by the concept 'electron'?justdrew wrote:electrons don't stand for anything anymore, all they do is spin.

And if you are saying an electron is constituted of a few quarks, it then raises the question of what is a quark in reality,..what is it constituted of for example?
No, my understanding of the reality represented by the concept of 'one' is clear, not so the true reality represented by the concept 'electron'. That it is composed of energy, spherical, spins, has an electric charge, has a magnetic moment, etc., describes it like the blind men and the elephant, but what is missing is the wholeness, the oneness of it in and of its environment.justdrew wrote:well, you can make them out of photons, if the photons have enough energy. so I guess the same thing "light" is made of. it may even be they're all little complex standing waves in the space manifold. so what's that?

Is 'reality' unreal? Scientists work on a way to find out
Physicists propose cosmic-ray experiment to test idea that we're living in a simulation
What if everything — all of us, the world, the universe — was not real? What if everything we are, know and do was really just someone's computer simulation?
The notion that our reality was some kid on a couch in the far future playing with a computer game like a gigantic Sim City, or Civilization, and we are the player's characters, isn't new. But some physicists now think they know of a way to test the concept. Three of them propose to test reality by simulating the simulators.
Martin Savage, professor of physics at the University of Washington, Zohreh Davoudi, one of his graduate students, and Silas Beane of the University of New Hampshire would like to see whether they can find traces of simulation in cosmic rays. The work was uploaded in arXiv, an online archive for drafts of academic research papers.
The notion that reality is something other than we think it is goes far back in philosophy, including Plato and his Parable of the Cave, which claimed reality was merely shadows of real objects on a cave wall. Sixteenth-century philosopher-mathematician René Descartes thought he proved reality with his famous "I think, therefore I am," which proposed that he was real and his thoughts had a reality.
Then, in 2003, a British philosopher, Nick Bostrom of the University of Oxford, published a paper that had the philosophy and computer science departments buzzing.
The Matrix hypothesis
Bostrom suggested three possibilities: "The chances that a species at our current level of development can avoid going extinct before becoming technologically mature is negligibly small," "almost no technologically mature civilizations are interested in running computer simulations of minds like ours,” or we are "almost certainly" a simulation.
All three could be equally possible, he wrote, but if the first two are false, the third must be true. "There will be an astronomically huge number of simulated minds like ours," Bostrom wrote.
His suggestion was that our descendants, far in the future, would have the computer capacity to run simulations that complex, and that there might be millions of simulations, and millions of virtual universes with billions of simulated brains in them.
Bostrom's paper came out four years after the popular film, "The Matrix," in which humans discover they were simulations run by malevolent machines. The popularity of the film possibly contributed to the attention to Bostrom’s paper received at the time, but nothing came of it.
"He put it together in clear terms and came out with probabilities of what is likely and what is not," Savage said. "He crystallized it, at least in my mind."
Looking for anomalies
In the movie and in Savage's proposal, the discovery that reality was virtual came when unexpected errors showed up in life, demonstrating imperfections in the simulation.
