What Happened When We Tried to Publish a Real Paper Investigating Time Travel

I'd be interested to see what arXiv's Impact Factor was if it was calculated like a standard publisher (if possible). I would guess it might be a top ten, based on my anecdotal encounter rate with arXiv (I may self select) and it seems like we're moving into another encyclopaedia situation (open Wikipedia stomps heavily curated Britannica).

Frankly, can't wait. Despite all the editor conflict, Wikipedia is still one of the best inventions of the new millennia and if we eventually evolve towards having all SOTA research publicly accessible at our fingertips anywhere ... heaven.

I wanted the punch line to be, "The Time Lords showed up and insisted we halt all experimentation."

Imagine: Google itself could find proof of this, given that it's organizing the world's information. In fact, Google is one of the only entities that could actually 'prove' this out.

What would they do if they identified the time traveller? Locate him/her? Use his knowledge to further their plans? The knowledge may be potentially world-changing; whoever finds the traveller will be in a very powerful position.

Script idea: Eccentric googler finds proof of this and the company secretly finds the individual. Wild goose chase ensues. State actors get involved. I'd pay to see that.

If this had already happened, would we even know?

>>seems like playing with fire

well, fusion is playing with fire (plasma) almost by definition.

The biggest issue that I see with publishing this work in a physics journal is that although time travel is certainly a concept in physics, the research involved here is not physics research. I'd describe it as sociological(?) research intended to shed light on a problem of interest to physics. That may seem like splitting hairs, but there's a real question of competence here: as a physicist, I don't feel especially qualified to assess the methods they used or the reliability of the conclusions they draw. If they were instead describing an experiment to look for anomalous travel times of neutrino pulses or something, I'd know where to start: measurement apparatus precision, clock synchronization, etc. But here the observations are based on natural language and the conclusions are based on theories of how information spreads in social networks.

Like most physicists, I have zero formal experience in this. It honestly doesn't feel like a topic for a physics journal even though a reliable positive result would have profound implications for physics. In the same way, I wouldn't expect a technical article reporting measurements of carbon flow in the environment to be published in a political science journal, even though climate change might have profound implications for global politics. [Discussion note: the validity of climate change has nothing to do with my point here.]

All that being said, I also don't find their negative result to be particular compelling. If their two search terms were "Pope Francis" and "Comet ISON" as described, well, Comet ISON was a dud (and thus won't be much of a topic in the future), and it's easy to imagine scenarios in which future time travelers would not have a particular interest in Catholic history. And that's quite apart from the possibility that time travelers would make some modest effort to avoid asking their neighbors about future events. Maybe that's all accounted for in their paper in a compelling way, but I honestly don't see any way they could ever argue for more than a very limited negative result. And I'm not convinced that's publishable in any sort of competitive journal.
