Some time ago I put together some animations for Wikipedia's article on "The Twin Paradox"
https://en.wikipedia.org/wiki/Talk:Twin_paradox/Archive_14#/media/File:Lorentz_Transformations_of_Twin_Paradox_Minkowski_Diagram.gif
Unfortunately, this animation couldn't go into the article on The Twin Paradox, not because the animation had any flaws, but because the animation was based on "Original Research"
I was given the impression that if I could find peer-reviewed journals that would publish a paper that promotes animated space-time diagrams in explaining the Twin Paradox, then Wikipedia could use such diagrams to explain it.
But failing to find peer-reviewed journals, I could write such an article myself. And perhaps find someone to peer-review it and publish it.
I'm now in that phase where I have already written a paper. I have sent copies of it, last August to some of the authors whose papers I was endorsing and/or criticizing.
And just now I uploaded it to ResearchGate as a "Working Paper", so it generated a DOI number. But apparently, now the paper is hidden from everyone unless I "share" it with specific people.
What should I do then? I'd like to make it so that whoever wants to see it can see it. But if I do that, would that make it so I couldn't get it peer reviewed? Because journals do the peer review, and it's not in their financial interests to publish articles that are already freely available on the web, so they would not have any incentive to peer review a paper that's already freely available.
