If you are aware of an interesting new academic paper (that has been published in a peer-reviewed journal or has appeared on the arXiv), a conference talk (at an official professional scientific meeting), an external blog post (by a professional scientist) or a news item (in the mainstream news media), which you think might make an interesting topic for an FQXi blog post, then please contact us at forums@fqxi.org with a link to the original source and a sentence about why you think that the work is worthy of discussion. Please note that we receive many such suggestions and while we endeavour to respond to them, we may not be able to reply to all suggestions.

Please also note that we do not accept unsolicited posts and we cannot review, or open new threads for, unsolicited articles or papers. Requests to review or post such materials will not be answered. If you have your own novel physics theory or model, which you would like to post for further discussion among then FQXi community, then please add them directly to the "Alternative Models of Reality" thread, or to the "Alternative Models of Cosmology" thread. Thank you.

"if the input is x, then do y"

Where then, y=f(x) and y is the so-called agent, but it really an action/output undertaken automatically/deterministically from x's.

And so no one is conscious y, but consciousness results from x brain states as emergent y, and another set of x brain states that produce y consciousness “observe” in as much as groups of x brain states produce y's.

If so, there are a lot of resulting consciousnesses, because there are a lot of brain states, but no one is actually conscious in the freewill capacity.

I wonder if an agent, or the act of observation, is kind of like causing a nucleation site to form, thereby allowing the "crystallization", or formation, of the state of affairs (e.g., what is observed) to proceed. What I'm thinking is as follows. Let's say that reality is made of little, jiggling membranes. One might call these strings, loops, or whatever. They have the potential to cause the formation of other membranes around them. This potential is what is called quantum probability. But, while the membranes are jiggling, there's no stable, unmoving surface that can serve as a nucleation site for this potential, or quantum probability, to collapse and cause the formation of the new surrounding membranes. This means, then, that the act of observation by an agent is just the ability to temporarily stop the jiggling of a membrane, thereby allowing a stable surface to be present and act as a nucleation site to allow the surrounding quantum probability to "crystallize", or collapse, and causing the formation of the new surrounding membranes and the appearance of the observer-caused state of affairs.

Just an idea I've been working on based on my own thinking. Thanks.

"Steinberg’s work on measurement, information-storage and erasure is intimately tied to a fundamental theorem of quantum physics that says quantum information can’t be perfectly copied."

In Shannon's Information Theory, any data or state that cannot be perfectly copied, is not information in the first place; When a system contains both "signal" and "noise", only the signal (AKA information) can be perfectly copied - that is the defining property of "information". Quantum states cannot be copied, precisely because they contain a great deal of noise, and not just signal; a single bit of information (like spin-up or spin-down) cannot exist without noise being present, since reducing the noise will necessarily enable more than a single bit to be detected.

Only humanly contrived finite mathematical symbols are functional. It would be physically impossible to add, subtract, multiply or divide any amount of INFINITE VISIBLE surface in order to increase or decrease its visibility. There are no finite fractions of the INFINITE VISIBLE surface. There are no finite decimals of the INFINITE VISIBLE surface.

Regarding the quantum measurement process in ‘interferometer experiments’ where ‘photons are made to travel along different paths’, as I understand it there’s a photon emitter (laser) and a receiver (such as a photosensitive plate), and some measurable distance between them as part of the whole laboratory setup. This is the observer’s lab world and for them there is an actual fact of...

Malcolm,

I live in a community in which every path (street) is a dead-end or cul-de-sac. There is only one way out. Hence, to catch (detect) a burglar trying to flee the community in a vehicle, the police do not have to send police cars to search out every possible path through the community; it is sufficient to simply put one detector at the only exit. All roads lead to that exist,...

@Rob, are you suggesting that photons objectively travel across the lab space as individual physical entities like a thief in a cul-de-sac?

This sort of classical simile for quantum realities is precisely the question isn't it?

Malcolm,

I am not merely suggesting it, I am attempting to point-out that the actual facts demand it. Photons travel like phonemes in a sound wave; a distinct, recognizable entity, but one that is only detectable/recognizable, to another entity that knows, a priori, how to properly detect it, in its entirety - all or nothing - just like identifying and catching an actual...

If thevunivrse is a close or open system this is out of the humanity competence. We cannot say any pros or disprove the possibility of quantum or black hole or other imaginary opportunities that can link the multiverse as a union. But we can take the assumption of the closed universe for the benefit of some theory solving the unknown. What does your respected and solid theory tends to solve as a physical or philosophical task. That is a question that is quite interesting.

Hello,

We have indeed many limitations due to our level of knowledges, we know so few still. What are the foundamental mathematical and physical objects ? what is the real universal philosophy creating these topologies, geometries. matters and fields inside this physicality. How the energy matters transformations act reall ? We have still many unknowns to discover and it is a big puzzle. I have a model , correlated with my theory of spherisation , an optimisation evolution of the universal sphere or future sphere and coded 3D quantum spheres and cosmological spheres , I consider a closed evolutive universe but can we affirm ? no we must accept our limitations and assumptions, we cannot affirm these assumptions respecting a deterministic logic.

Regards
