Several folks here have recognized that the spin direction depends on whether you look at the plane of the galaxy from ‘above’ or ‘below’. One thing I didn’t see in the article is how the two types of galaxies are distributed across the 3D spherical coordinates when viewed from the earth (or rather from the JWST).

Im thinking: what if there are a bunch of massive objects like black holes in certain directions that are causing the light to bend in a certain way. So what would normally be light coming from the top of the galaxy plane, is actually light reaching us from the bottom of that plane. Would this slew the distribution of the spin one way - I don’t know.

Thank you. That's a shame, it was a cool-sounding story, just unlikely enough to sound plausible.

Space and time are related, and expanding rapidly since the Big Bang (though there was a time in the early universe when the expansion rate was faster). https://cds.cern.ch/images/CERN-HOMEWEB-PHO-2022-023-1 Observing the edge is effectively looking back in time, to see the conditions of the universe closer to the time of the Big Bang. New telescopes keep expanding that edge, and new particle colliders (such as those…

I thought the expansion of space which is faster towards the event horizon has no impact on the Lorents factor. But I might be wrong.

I think you're right, except for the spelling of Lorentz factor.

The equation is on Wikipedia. https://en.wikipedia.org/wiki/Lorentz_factor

The terms are: v is the relative velocity between inertial reference frames, c is the speed of light in vacuum, β is the ratio of v to c, t is coordinate time, τ is the proper time for an observer (measuring time intervals in the observer's own frame).

If we could compare the time as we know it (based on the SI unit of seconds using an atomic clock) against the time at the singularity at the centre of the universe, we could figure out whether we're in a black hole, whether we're at the event horizon, or whether we're outside.

But we would have to assume space is a vacuum, which isn't entirely true.

Wow and not even 24 hours after Trump takes aim at the Smithsonian.

Some say god is light. maybe it was a high energy photon that met its antiphoton.

I say that god is just the universe

> The observable universe is expanding into the unobservable universe. Is that so? My understanding is that it doesn't expend into something. And that it expend so fast that the edge of it becomes unobservable.

Thats just a distinction between the Observable Universe and the Universe. The observable universe should be labeled "Our" Observable Universe as what is observable depends on where you are. Imagine a sphere growing outward at the speed of light, this is what is observable this region is aka the Hubble Volume. Right beyond the edge there just hasn't been enough time for the light to reach our location. No woowoo requ…

There is only one Entire Universe; it's not a multiverse. And we observe it as a sphere, sized by the speed of light in every direction.

Trying to see beyond the edge would be like trying to peer out of a black hole. It would probably look blue, like Cherenkov radiation. (but I'm biased, due to having blue eyes).

If the Entire Universe is infinite, then it's eternal in time. And then we get philosophical again.

That would be super cool to find out! And then it also begs the question, is there something at the center that unites the two poles? If so then what is it! It would also imply that our whole universe is rotating - the only reason this happens on Earth is because of our planets rotation and the Coriolis effect.

*raises the question

Off-topic, so I hope not to spark too much side discussion here.

While I agree with your correction and this always bugs me, the common usage of the phrase "begs the question" seems to have become synonymous with "raises the question", as opposed to what I understand to be its former — and perhaps original — meaning which was associated with the informal logical fallacy by the same name.

Ok but what is making the universe spin? This kind of theory is turtles all the way down.

Is this getting into questions like "Where did the singularity come from?" and "What came before the singularity?". We don't have a way to answer these kinds of questions.

My point is that it's not much helpful to say, "galaxies spin a certain way because the universe spins", because it shifts the problem without actually answering the "why". "Turtles all the way down" is a saying about such infinite regress. https://en.wikipedia.org/wiki/Turtles_all_the_way_down

And yes, I'm familiar with Dawkins' famous retort when someone asked how magnets repel things.

Is this just word association, or you saying there’s some notable connection here?

The author is also a proponent of tired light theory, which has been thoroughly refuted.
