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.

Essay Abstract

We introduce notions of classical and quantum predictability. We argue that it is possible that the merging of gravity and quantum theory imposes limitations to quantum mechanics and a weakening of predictability. Possible consequences for physics, mathematics and computer science are discussed.

Author Bio

I have completed my PhD in the University of Geneva in 2016, under the supervision of Nicolas Gisin. After a brief post-doc at the same institution, I have moved to PUC-Rio, to start a laboratory aimed at quantum optomechanics experiments applied to fundamental physics.

"It is known beyond reasonable doubt that the universe is undergoing a period of accelerated expansion due to what is effectively described as a cosmological constant [5]. The further things are from us, the faster they recede. . . [5]  Perlmutter, S., "Measuring the acceleration of the cosmic expansion using supernovae", Nobel Prize Lecture, December 2011 ...:

According to Perlmutter, "Hubble's observations indicated that we don't live in a Universe that is standing still ..." — is Perlmutter correct? Is Milgrom the Kepler of contemporary cosmology? Has Perlmutter underestimated Milgrom? I conjecture that Riofrio, Sanejouand, and Pipino are geniuses who are not appreciated by the majority of cosmologists.

Dear Thiago,

I greatly appreciated your work. I am very glad that you are not thinking in abstract patterns.

While the discussion lasted, I wrote an article: “Practical guidance on calculating resonant frequencies at four levels of diagnosis and inactivation of COVID-19 coronavirus”, due to the high relevance of this topic. The work is based on the practical solution of problems in quantum mechanics, presented in the essay FQXi 2019-2020 “Universal quantum laws of the universe to solve the problems of unsolvability, computability and unpredictability”.

I hope that my modest results of work will provide you with information for thought.

Warm Regards, `

Vladimir
