Murdoc, 8 miesięcy temu do astronomy w Huge star explosion to appear in sky in once-in-a-lifetime event

I wonder if there’s a way to get an alert or something so I don’t miss it. I tried searching for one but so far no luck.

I don’t think there are many black holes in Rome. But I suppose they really want to make sure.

Does that exactly the same sentence in the first two paragraphs indicate an AI writer?

I stopped reading at that point.

btaf45, 5 miesięcy temu do astronomy w Astronomers discover two new Milky Way satellite galaxy candidates

If the distribution of those nine satellite galaxies across the entire Milky Way is similar to what was found in the footprint captured by the HSC-SSP, the research team calculates that there actually may be closer to 500 satellite galaxies

WTF? I was thinking there were around a dozen or so.

They solved one conundrum just to find another. Too few dwarfs then too many.

Is dark matter just dwarf galaxies?

ekZepp, 4 miesiące temu do astronomy w Scientist performs the first nonlinear study of black hole mimickers

A nonlinear study refers to an approach that does not follow a straight, sequential path in analyzing or modeling phenomena. Instead, it allows for complex relationships where changes in one variable do not directly correspond to changes in another, often leading to unpredictable outcomes. In the article, a Princeton scientist explored the nonlinear dynamics of boson stars, a type of black hole mimicker. His research revealed unique gravitational wave signals during mergers, distinct from those of traditional black holes, which could aid in identifying these mimickers in future gravitational wave observation

And we found the MVP. Cheers to you, mate, and your explanation, thanks!

This works here but maybe also in shitjustworks/c/spaceflight too. Or lemmy.world/c/space. Those are both pretty active space communities.

foofiepie, 3 miesiące temu do astronomy w Astronomers discover biggest ever seen black hole jets, which blast hot plasma well beyond their own host galaxy

Ok. Permission to ask a mad question. Apologies in advance.

If black holes ‘suck’ everything in… could there be the equivalent of the ‘other side’ of one, that’s mysteriously ejecting a tonne of plasma?

Not saying that’s what this is, just prompted the thought.

Mathematically, it’s possible, but scientists are still skeptical about whether or not they are real. They’re called white holes and you can actually create a model of one in your kitchen sink. If you let the water just hit the bottom and spread out evenly in all directions, you can kind of visualize the way it’s supposed to work. Action Lab on YouTube actually has a pretty good video about it which I suggest watching if you’re interested. youtu.be/p3P4iKb24Ng?si=b3_RHuj0J3F_7DC1

Tangent, but you don’t need to include the question mark or anything after in most urls. Definitely not YouTube links. It’s just YouTube telling itself who shared the info (you) and they use that to track shit. But the link works just as well without it, and you’re not voluntary spying on yourself.

Neat! I didn’t know that. I just copied and pasted. Thanks for the info.

If it can be infinitely dense inside a black hole, doesn’t that mean the scale doesn’t matter and that the ‘inside’ is pretty much it’s own whole universe with different physics rules?
