Another Dark Galaxy!

Unread post by BeAChooser » Fri Feb 10, 2023 11:41 pm

According to https://www.sciencealert.com/mysterious ... ntists-say , a
newly discovered dwarf galaxy located a mere 94 million light-years away is defying expectations. It's named FAST J0139+4328, and it's not emitting any optical light. In fact, it's barely emitting any light at all. FAST J0139+4328 appears to be what is known as a dark galaxy. Aside from a small smattering of stars, the galaxy seems to be made up almost entirely of dark matter.
Here’s the paper on it … out of Communist China …

https://arxiv.org/pdf/2302.02646.pdf

The article states that the "dark matter theory isn't perfect … snip … One problems is a discrepancy between simulations of the dark matter distribution in the Universe and the number of dwarf galaxies we see out there orbiting larger galaxies. There are way fewer dwarf galaxies than the simulations suggest there ought to be.” Then is suggests that maybe the missing dwarf galaxies have very few stars and consist primarily of gas and dark matter, and
[t]o search for such a galaxy, Xu and his colleagues used the Five-hundred-meter Aperture Spherical radio Telescope (FAST) in China. They used the telescope during gaps in its observation schedule as a ‘filler’ project to conduct a search for the radio emission of large clouds of neutral atomic hydrogen (HI) gas in intergalactic space, looking for features consistent with a galaxy. And they got a hit: the radio waves emitted by a cloud of HI 94 million light-years away were consistent with a rotating disk galaxy, without the optical light expected of one. Follow-up observations in infrared and ultraviolet revealed a faint smattering of stars. … snip … According to the team's calculations, the galaxy has an upper limit of 690,000 solar masses' worth of stars – and it contains 83 million solar masses' worth of HI. The total baryonic mass of the galaxy clocks in at around 110 million solar masses. This, however, is just a drop in the bucket of the galaxy's total mass. The team was able to calculate FAST J0139+4328's rotation speed, and from that its total mass, which came in at 5.1 billion solar masses. That would mean that the galaxy is made up of around 98 percent dark matter.
Then the article mentions the previous case of a galaxy called Dragonfly 44 which in 2016 was found to be consistent with 99.99 percent dark matter. “Four years later, however, astronomers determined that Dragonfly 44 wasn't so abnormal.” So take this new *dark galaxy* with a grain of 盐.

I have another theory: God created the Universe.
Searching for him would of course be useless, because he can do anything and explain anything, resolve any observed "anomalies", just because he can do it, "by magic".

We are not content with such explanations like "by magic", except in the case of "Nothing existed then it exploded, by magic.".
We seek real answers! So instead of searching for God we search for things like "dark matter" and "dark energy", and we know that these are things with all the properties needed to explain everything...
We know everything else perfectly, and it perfectly makes sense. What does not make sense can only be explained by magic stuff with exactly the needed properties.

By this "reductio ad absurdum", I showed what happens when you give up science. "There are so many things to figure out, we are bored, we will suppose that this magic dark stuff does exist, (it's not God, nothing religious or imaginary here) and it will have all the needed properties to explain everything". Simple, now everything is explained, all that's left is to search for the stuff, but that's a minor detail. Anyone who tries to do real science will be ridiculed, because we already explained everything.
