SemanticStrength&amp;#x27;s reply to you also implies this was written in the 90s. The PDF has the 1997 date on the clickable link back to the arxiv, so there is some time-travel going on that I do not understand. The date of the preprint is important context, for reasons I&amp;#x27;ll return to at the end, wrt your point about the CMB. &amp;gt; huge red flags Are there? I&amp;#x27;m not sure I agree. &amp;gt;…&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/gr-qc_0104013/"&gt;Paper and discussion history&lt;/a&gt;.
