Very Large Telescope just gave another big destructive hit to standard science...

3I/ATLAS is bleeding nickel at levels no comet should, defying physics, and dwarfing anything we’ve seen before, including Oumuamua and Borisov.

How about posting the paper instead of a xitter link?

The Dark Forest tossed a fucking rod at us.
They're going to destroy Mars as a lesson to us and hopefully false flag the local tigers into thinking we self-heroed our civilization.

I'm struggling to find where where the paper concludes this?

It doesn't and like usual it destroyed OP
>>
>>16803022
Pretty sure they know it's a rockball and not a snowball. Makes sense it would eject nickel.
Not like they make planets out of that stuff or anything.
>>
>>16803029
Nope other work shows the coma is dominated by CO2, with H2O and water ice.

https://arxiv.org/abs/2508.18209

Also, as you can see from the measurements in that paper, all comets eject some amount of nickel.
>>
>>16803078
Oh dear, a "surprising" amount of nickel. That could mean anything. Thank you scientists for nailing this one down too!

Let's assume it's artificial. Loeb stated that its perihelion (nearest point to the Sun) is exactly opposite to the Earth, and that that is the most efficient point to make a course adjustment. The possibility discussed is that if it were to make such an adjustment it would be in order to circularize its orbit around the Sun. But it seems to me that such an adjustment could achieve another result: to hit the Earth and wipe us out. A civilization some light years away might know we're here from all the radio noise, and have worked out what planets exist in the solar system but not know which planet is producing all the radio signals. 3I/Atlas has to get close enough to determine which planet to hit. Making the appropriate orbital adjustment behind the Sun means that when it emerges into view it will be too late for us to do anything when we see that it coming straight at us.

I recall a paper that showed that all you get by nuking an asteroid is a cloud of small asteroids that coelesce back into a more or less solid ball. Anyway, even if it doesn't coelesce before hitting Earth, you get hit by a shotgun blast instead of a single bullet.
>>
>>16804264
However, further thought makes me aware that if the aliens had an idea of what planets there are and where their orbits around the Sun, and assuming they are seeing the solar system edge on, they would know which planet is producing radio noise because the noise would stop when that planet was behind the Sun from their point of view. If they are not looking at the solar system edge on, and the planets are always visible, then they'd need to measure slight doppler effects on one or two radio signals of the relative motion of the planets.

Clickbait like this is why science is so Reddit and cringe now. Literally kill yourself.

I'm not clicking one of those links ever the fuck again.

why are we still posting this hack?

Stupid question but what does the I mean in FeI and NiI? Are they just Fe+ and Ni+? I take it they are not iodides lol
>>
>>16804355
FeI is just neutral Fe actually. I is neutral, II is singly ionised.

whats the chance of this "bullet" arrives when we are just capable to observe it? this will be new norm soon, weird objects coming and going

Mars already got giga-nuked twice millions of years ago. It is coming to make sure it is still a dead rock.
>>
Of course there’s shit out there that our own understanding of physics can barely follow. We update physics.

Why does this piss scientists off again? Because it’s like admitting magic exists?

There are far more efficient ways to exterminate potential threats, like deploying biological weapons able to make a civilization destroy itself. Methods that releases or involve high amounts of energy attract too much unwanted attention.

>>16804432
Giving power to the unknown is le bad.

There’s unexplainable shit on our planet already and we’re omg’ing at space? I’m in love.

>>16804264
shotgun blast is fine-ish, most stuff would burn up in the atmosphere; the impactors would cause much more damage in terms of blast and thermal effects but you don't run a risk of megatsunamis, mantle cracking or anything wild like that
four years of winter and maybe a few millioin dead from prompt effects. not great, not terrible
>>
Mars Reconnaissance Orbiter photos soon.
>>
>>16804436
NTA, but I would think sending an expedition to an alien civilization and launching a project to understand their much different biology in order to develop a disease which they might be able to counter would be a lot harder than sending a huge rock to home in on radio signals. And what unwanted attention? From the target civilization? Don't give them time to respond. From other civilizations? If they're close enough to detect a chunk of rock hitting a planet in another solar system, they're already in your crosshairs as well.

You fail to account for how big and empty the space is.

Anyone else finds it funny that at this exact moment pic related happens?

This is ridiculous speculation. It's a space rock that will be flying out of our solar system and we'll never see it again.

they obviously nuked it wrong, you detonate below surface at such depth that you vaporize material above explosive and this material weighting hundreds of tones shoots into one direction at above escape velocity, while rest of asteroid goes other way.
