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.

FQXi Member T. P. Singh of the Tata Institute in Mumbai, India, kindly provided us with slides from a talk he delivered last summer in Trieste, Italy. The topic was his team's research into Quantum Mechanics without time and the measurement problem.

We'd like to share the slides here so that interested parties can discuss Dr. Singh's work.

You can find another interesting article from Dr. Singh and collaborators on the topic of foundations of quantum mechanics, on the arxiv here. This article is coauthored by another FQXi Member, Hendrik Ulbricht of Southampton University.

Dr Singh states in the abstract of his arxiv paper, in relation to quantum mechanics:"The theory is not contradicted by any experiment."

You may be interested in a set of experiments that do clearly contradict quantum mechanics. It is in the 2012 FQXI essay contest:

A Challenge to Quantized Absorption by Experiment and Theory

A singly emitted quanta of light should go one way or another at a beam splitter. There should not be coincident detections in a pair of detectors past a beam splitter except by chance. Using singly emitted gamma-rays, I show coincident detection rates greatly exceeding chance. I explain why gamma-rays are necessary to see through the photon-model illusion. A similar set of experiments were also performed with alpha-rays, greatly exceeding chance. A convincing version of the experiment is simple enough for a student of physics to re-enact with a single gamma detector and pulse height analyzer. I explain it with the Loading Theory, and seems to resolve the measurement problem. Hope you like the essay. Eric Reiter, 8/2012

This is just the area of physics that interests me: resolving the long standing problems presented by Quantum Mechanics, i.e. the measurement problem. I shall have to keep an eye on Dr Singh's work and any research that it prompts; it does look very promising.

Although it is unlikely to compete with the well thought out theories of mainstream academics, I, myself, have put forward a new interpretation of quantum mechanics which does solve the measurement problem and the actual time asymmetry of wavefunction collapse.

Currently the concept is in its early stages and will certainly need a much more rigorous mathematical description (unfortunately, I am not noteworthy enough to have my pre-prints on arXiv so it is on viXra instead): Quantum Theory in the context of a block universe model

In my interpretation, as in Hugh Everett's "many worlds", all outcomes of wavefunction collapse are realised however, since there is no 'present moment'; each event is casually disconnected from all others - in this way instead of space-time being thought of as one continuous Lorentz manifold, it is thought of as each event constituting individual, separate manifolds much like fibres of a bundle.

Brendan thank you for this. I do appreciate all of the helpful resources, articles and food for thought provided by this site and the FQXi members and community.

It is interesting to see what other people have been working on and how it is presented. Rather than discussing Dr.Singhs work right now I'd like to wait until after the competition closing. He may also have another entry to this years competition to share, which may include what he has been working on.

Dear Tejinder,

You are on the right path to understanding the quantum nature of our being.

There is only one absoulte individual quantum entity (singularity) and the entire universe is in it. There is no space unless one chooses to measure and there is no time until one chooses to count. There is no space-time besides one absolute self. I have put forth the universal truth in the following topic

Conscience is the cosmological constant.

Love,

Sridattadev.

I have read the PPP carefully and think it is a little bit funny; I explain.

The goal is to describe QM without time and the measurement problem. What means the description of reality without phenomena.

Reality without phenomena is "the unknown universe" of the absolute time and absolute space of Isaac Newton. And that in contrast of the commen time and commen space: the "empiric world" of Albert Einstein. Whithout phenomena no curved spacetime.

A universe without phenomena consist of flat fields. So everywhere, there is een flat scarlar field and there is a flat vector field and they don't interchange: the abstract world of the MUH (mathematical universe hypothesis). Theoretical physicist manage applied mathematics to describe the relations between the phenomena, so the team have to make up there mind. Will they remain theoretical physicist or will they become philosophers/mathematicians?

Suppose they make the right decision...

They will soon realize that science = phenomena. Even ontology is for the most part a description of the relations between - classification of - phenomena. Despite this they have to describe static space (flat fields) and have to orientate themselves in this ERH (external reality hypothesis).

Suppose the group succeed. They describe the elements of the set (space), recognize the topological attribute, discover the mechanism that take charge of the separation of one field (the infinity set) into a vectorfield and a scarlar field, realize themselves that the universe is “analog” but interchanges “digital” and... (we are now near page 12 of the PPP) they want to keep on with fulfilling the dreams of a “lousy” physicist: stumbling within common space and common time. That’s funny.

Quantum mechanics rest on our understanding of the wave function. Mathematician recently produced a proof which proved wave functions are not just mathematical tools but real structures. About eleven months before that proof, the Indian Journal of Science and Technology published my research which successfully isolated wave functions within the motion of binary stars. Anne Astronomy News reported the findings.

In layman's terms, a space wave is a wave function.

As scientists edge closer to breakage of the Standard Model

https://www.nature.com/articles/nature21721

the ultimate identification of what we actually are as a physical and metaphysical unit creeps closer to reality.

"Conscience is the cosmological constant." Nice.

I viewed this thread with interest as Tata is the company to take over Corus Steel where I delivered my first programme based on quantum mechanics to a written-off workforce who subsequently broke performance records. Week 1 looked at The Singularity, defining its (our) place in the social matrix. Quantum mechanics and its principles are not 'out there', they are part of our own mechanism, and we can happily await the time when physics acknowledges this duality on an open basis. Then we can move forward in progressing the understanding of not only the Universe, but the truth of our place within it.
