Everything we know about Sagittarius A Seems to be Wrong

So, Sagittarius A* might not be a black hole at all …
Whereas some data observed in the center of our galaxy is explainable by proposing the existence of a supermassive black hole (which we all know as Sagittarius A*), there are some observable facts which are not explained by this hypothesis. Now a very recent paper proposes something completely...

Hint: Do not use MSN (or any other popular presentation) as a reliable source on current science.
I could relate to that, but this link is a bit more serious? https://arxiv.org/pdf/2105.06301.pdf
Popular Science/Mechanics has a history of resorting to sensationalism in their articles, going back multiple decades. I wouldn't consider them a "source", especially when linked to a clickbaity thumbnail on MSN.
So, another classic scientific: "we don't really know".
Very amusing.
Very amusing.
If it's dark matter, what's the galaxy revolving around? I didn't think dark matter had a gravitational effect?
Indeed, it takes mastery to comprehend true depth of most fields of knowledge. As a wise old greek man once said: "I know that I know nothing".
My understanding is that gravity is the only force through which dark matter interacts. Or at least all other interactions are hypothesized to be very week in comparison.
That's a great white paper. Thanks for sharing. Got some reading material while i'm shuttleing around with Apex.
The galaxy isn't "revolving around Sag A", at least not in the same sense that the planets revolve around the Sun. Sag A only comprises a tiny percentage of the galaxy's mass. If you could magically take away Sag A, most of the galaxy would continue happily revolving around itself, just as it does now.
Of course it does, that's the whole thing about dark matter. There is gravitational pull, but there is nothing there.
Or I may be totally wrong here..

You can always tell when somebody/something doesn't understand the Scientific Principle when they say "Aha! The scientists might be wrong!!!"
Yes.
That's the whole point of the Scientific Principle.
You form a hypothesis, you keep testing it and the results will either conform to your hypothesis or you'll modify your hypothesis.
Learning is not failure.
It's only stupid people who can't seem to grasp that.
It's phlogiston.
