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
This is a pop-science problem and not a real science problem. Any astronomy imaging system worth its salt has image stacking algos that remove transients easily enough.
Hi, it’s me. An actual scientist. Did grad school in planetary science. The same techniques we use to spot asteroids are the techniques used to spot satellites. But removing them is even simpler. It’s not algorithmically hard at all.
In fact, it’s so simple that I’ll write it out: take several images (at least three) in quick succession and take the median value across those images.
Oh hey, that was easy. Makes a good despeckle filter too for cosmic ray strikes or whatever else.
I mean, I’m pretty sure you’d be able to see it from everywhere in Australia, so I bet many of them would be like “WTF?” But they’ll be dead soon. Fuckin’ kangaroos.
The light blue part is shallow and when it’s underwater, they call it “continental shelf”.
Tasmania and mainland Australia are connected by the same, shared continental shelf.
If that photo was taken right before impact, none of the continents will remain continents because it’s all about to melt and we might have another moon when everything settles down and we evolve back from scratch over the next several billion years.
