I Most Ridiculous Papers You've Ever Read

AI Thread Summary
The discussion centers on a retracted 1998 paper proposing a design for a quantum time machine based on a non-causal interpretation of Quantum Mechanics. The author claims that this theory allows for the possibility of seeing into the future without causing time paradoxes. Participants note that many similar papers often reflect a disconnect between theory and experimental validation or present overly confident interpretations of results. The thread emphasizes the importance of adhering to mainstream scientific discourse, as speculative theories can lead to confusion and misinformation. Ultimately, the conversation highlights the challenges of distinguishing credible scientific work from less rigorous claims.

A Design for a Quantum Time Machine

Andrew Gray, submitted 2 Apr 1998

ABSTRACT
"In the new ``History Selection'' formulation of Quantum Mechanics an entire cosmic history is selected over all space and time, with a probability for selection assigned to each possible history. As this probability depends on the whole history, and is not merely composed of the product of probabilities for each step in the history, the theory is not a causal theory. It shall be shown that this violation of causality is usually completely unobservable and confined to the microscopic world, occurring inbetween ``observations''. However it shall also be shown that in certain special circumstances it is possible to exploit the intrinsic non-causal nature of the theory to violate causality at the macroscopic level. A practical design for a device which can exploit this effect is shown. Such a device would effectively enable one to see into the future, and is thus a kind of time machine. Finally it shall be shown that, according to this new formulation of Quantum Mechanics, this does not give rise to any unpleasant time paradoxes."

I came across this while I was browsing through arXiv.org, submitted back in 1998 and funnily enough removed in 2004 with an amusing note: "This paper has been retracted, for obvious reasons."

Initial submission link: https://arxiv.org/abs/quant-ph/9804008v1
Retracted version: https://arxiv.org/abs/quant-ph/9804008

If you came across similar, or even more ridiculous papers please do share. Hopefully the links work, if not let me know.

Most were read as a peer-reviewer and never made it into print.

It would be a violation of the referee terms to say much about anyone of them.

Usually, there is a big disconnect between theory and experiment or an overly broad or confident interpretation of experimental results.

Sometimes, it is just a bad experiment that had no chance of testing the hypothesis that it was designed to test.

I do recall a published paper saying that the force (between bullet and tissue) is in no way related to the local rate of change of the bullet's kinetic energy. In other words, it directly contradicted F = dE/dx.
 
Thread closed pending moderation
 
Due to the nature of these kinds of papers, we feel its best to close this thread. PF focuses on mainstream science and doesn't discuss personal theories or speculative science. Posting paper references like these would lead to a host of problematic posts.

In closing, I'd like to offer this Sciam article:

and its reference to the book:

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
