Rowan Brad Quni<p>A key prediction derived from <a href="https://mstdn.science/tags/autaxys" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>autaxys</span></a> is that observations at very large redshifts (early <a href="https://mstdn.science/tags/universe" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>universe</span></a>), may reveal anomalies or deviations from standard cosmological models that are not explicable by <a href="https://mstdn.science/tags/darkmatter" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>darkmatter</span></a> or dark energy but are consistent with the hypothesis of evolving <a href="https://mstdn.science/tags/autaxic" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>autaxic</span></a> laws or large-scale autaxic <a href="https://mstdn.science/tags/spacetime" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>spacetime</span></a> dynamics.

Hi selves! This all takes place in one year. There's the original us, there's us leaving the present, and there's us meeting our past/original selves a year earlier — standard <a href="https://aus.social/tags/boilerplate" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>boilerplate</span></a> <a href="https://aus.social/tags/scifi" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>scifi</span></a> <a href="https://aus.social/tags/movie" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>movie</span></a> <a href="https://aus.social/tags/script" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>script</span></a>. </p><p>Alpha Centauri will have to wait another 3 years before any of this information can get to there.

This doesn't sound quite so much like birthing a twin universe, does it? Now what about the North Star? It will have to wait 433 years for news of our Time Travel event(s). And that's still pretty much in our tiny <a href="https://aus.social/tags/celestial" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>celestial</span></a> neighborhood. </p><p>The point is that the effects of such events are largely localized and rapidly diluted as we move farther away. This still has its paradoxical problems, but it doesn't quite feel like the whole universe dividing into two — maybe part of it (a universelet? a subuniverse?) Possibilities are that in moving further out in space-time, the effects of a Time Travel incident may be 'blurred out', as are anomalous numerical samples in the law of large <a href="https://aus.social/tags/numbers" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>numbers</span></a>. If one pours a cup of coffee into a lake, it doesn't change the color of the lake.
