Large accounts were published on this debate [10, 12–14]. Two sort of claims are recurring. Ignoring previous literature, there is a long list of scholars who pretend having discovered repulsion. They are listed in [10, 12–14]. The other concerns…&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/1708.00799/"&gt;Paper and discussion history&lt;/a&gt;.
