Is our universe trapped inside a black hole? This JWS Telescope discovery

An alternate hypothesis which seems equally interesting, albeit for different reasons, is at the end of the article:<p>&gt; Another explanation for why the JWST may have seen an overrepresentation of galaxies rotating in one direction is that the Milky Way&#x27;s own rotation could have caused it.<p>&gt; Previously, scientists had considered the speed of our galaxy&#x27;s rotation to be too slow to have a non-negligible impact on observations made by the JWST.<p>&gt; “If that is indeed the case, we will need to re-calibrate our distance measurements for the deep universe,&quot; Shamir concluded. &quot;The re-calibration of distance measurements can also explain several other unsolved questions in cosmology such as the differences in the expansion rates of the universe and the large galaxies that according to the existing distance measurements are expected to be older than the universe itself.&quot;

This newsblog takes one piece of the paper [1] and blows it up like it&#x27;s the most obvious thing ever and completely hand-waves away the alternative, while the paper itself actually provides some compelling evidence for the alternative explanation: This asymmetry is because of our own galaxy&#x27;s rotation. It would be an insane coincidence to have the large scale structure of our universe be more asymmetric towards the poles of our galactic plane and the further you go away from our galaxy (especially when velocity blue shifts would obviously make one type of rotation for galaxies more visible in the high-z regime where JWST primarily looked). Forget black hole cosmology, if you believe what this article suggests, then special relativity itself may be wrong. The data is pretty sound and perfectly in line with earlier observations that found no asymmetry if you believe our own galaxy&#x27;s rotation is the culprit. So if I had to bet, I&#x27;d say we misunderstood galaxies and not the universe as a whole. Mostly because galactic physics is incredibly complicated and has very whimsical empirics, whereas we have some really solid theories and data on the universe as a whole.<p>[1] <a href="https:&#x2F;&#x2F;academic.oup.com&#x2F;mnras&#x2F;article&#x2F;538&#x2F;1&#x2F;76&#x2F;8019798" rel="nofollow">https:&#x2F;&#x2F;academic.oup.com&#x2F;mnras&#x2F;article&#x2F;538&#x2F;1&#x2F;76&#x2F;8019798</a>

&gt; These [baby] universes would be unobservable to us because they are also behind an event horizon, a one-way light-trapping point of no return from which light cannot escape, meaning information can never travel from the interior of a black hole to an external observer.<p>Also meaning that “our” blackhole (the one containing us) is unobservable from the parent universe for the same reason. So where is all this extra light&#x2F;energy going in our universe? Should we not have detected an increase of energy in our universe?

It&#x27;d be neat if the universe were essentially a nested Russian doll of black holes. Our universe is a black hole with black holes inside and black holes inside them and so on, and the larger universe outside ours is also an even bigger black hole. Some of the <i>really huge</i> black holes in our universe might be big enough to host interesting things within, but the smaller ones probably just contain &quot;toy&quot; universes without much happening.<p>I recall reading about our universe as a black hole once -- one thing posited is that everything that is happening and what we think of as <i>space</i> is really information processing occurring just at the surface of the event horizon. There was some possible way of explaining non-local phenomena like entanglement that way, but I forget the details.<p>It&#x27;s fascinating to think about how the <i>actual</i> universe might be something quite alien from our ordinary perception. It&#x27;s not that our ordinary perception is wrong. What we&#x27;re perceiving is just one <i>perspective</i> on something much larger and weirder. In this case our perspective would be from <i>within</i> this information substrate. It&#x27;s almost universe-as-simulation, except that the simulation does not have a builder. It&#x27;s a naturally occurring phenomenon. The Matrix has no architect, or if it does it&#x27;s something fully outside the event horizon of this object and thus un-observable.<p>Of course at this point we&#x27;re well into physicists smoking pot territory.

at the bottom of the article the mundane hypothesis is presented that the measurement seen by JWST might be a calibration error caused by the rotation of the Milky Way making it appear that other galaxies have a preferred rotation.<p>sadly, this is likely the real explanation, but that&#x27;s not very exciting

How does this work with matter falling into &#x27;our&#x27; black hole and hawkins-radiation leaving our black hole? Heck, Hawkins radiation means black holes can evaporate. Does that correspond to a universa collapsing?<p>Would matter falling into our black hole come shooting out of the white-hole we see?<p>Would time on either side of the event horizon even be related?

&gt; &quot;The discovery by the JWST that galaxies rotate in a preferred direction would support the theory of black holes creating new universes, and I would be extremely excited if these findings are confirmed.<p>Its an interesting theory but to be honest, given the conditions of the event horizon, I don’t see HOW it could be proven.. That said I do feel this will turn out to be a nuance of the measurement itself but maybe that’s just my mind not comprehending the scales of what’s being measured here.

Does this mean we could look at deep space for clues about the physical rules that govern what happens beyond a black hole&#x27;s event horizon?

This result is a big deal, and actually seems under-hyped. None of the explanations make any sense.

i have always been wondering if the added up velocities of a series of rotating sub-systems has a relativistic effect that impacts what we observe and measure. the moon is rotating itself, around the earth, which is rotating around the sun, which is rotating ...

Some confusion in this thread. I think it would help folks to know that in addition to conservation of energy, our universe has conservation of angular momentum, aka mass spin.<p>Hope that helps!

Ok but then the theory of black holes are wrong because this isn’t dense at all.
