Matt Yglesias circa 1964, Dems should drop civil rights. circa 2005, Dems should drop gay marriage.

Sometimes in politics you have to do unpopular things that are nevertheless right.

It should do. Seeing as you are claiming to have a picture from the future. Or from before it was discovered.

I really wouldn't choose red.

They will. Especially if you are willing to call out the source of the nonsense.

3I/ATLAS: Does it Really Have 40% Chance It's Alien?
YouTube video by Mark Norris 3I/ATLAS: Does it Really Have 40% Chance It's Alien?

I made a (relatively) short video looking at the 8 reasons Avi Loeb thinks 3I/ATLAS has a 40% chance of being aliens.

I’m not impressed.

Offering a referendum on rejoining the EU seems like the obvious hail mary.

It’s also less reflective than tarmac/asphalt, probably formed when something the size of Mars hit the Earth, and is moving away from the Earth at a few centimetres per year.

That’s most of the basics.

I doubt it. Oumuamua is moving much slower than 3I but it is almost 50 AU away already. You'd need a massive amount of delta V just to reach it, a long time from now, and when you got there you'd be in complete darkness, and so far from Earth it would be challenging to send any data back.

I don't know what the deal is in his case. But it's definitely true that some very successful scientists go very cranky later in their careers.

Any actual astronomers who study comets on the "its aliens" side yet?

Not just selling a book. Pushing for the UN to make him director of an organisation with a budget of $100 million a year, and give him absolute control over the all the world's telescopes.

Not for this thing. It's already too late.

There is already a mission funded, Comet Interceptor. It is planned to intercept an unknown-at-launch solar system comet, but if the right ISO comes along it could go to that instead.

Also just noticed the poster guy has five fingers, when Futurama characters (like the Simpsons) generally only have 4.

Morale in some areas of UK academia might be a bit low right now, but some people still have a (good) sense of humour.

What are the odds that the plans for this look xeroxed with Falcon 9 crudely crossed out and Zhuque-3 written in the corner in biro?

The things you think of as sinister, out of simple ignorance, are fascinating insights into how solar systems vary.

You literally don’t understand the first thing.

Most of the things you list have been observed in other comets.

Others are flat out false.

Its reflection spectrum is completely consistent with D type asteroids and is less red than Pholus.

I’m not attacking you. I’m just pointing out you are wrong.

You haven’t presented any evidence that anything has been withheld. For all you know most mars probes didn’t try to observe 3I/ATLAS because it wasn’t possible or would risk their core mission.

25.10.2025 14:18 β€” πŸ‘ 1    πŸ” 0    πŸ’¬ 0    πŸ“Œ 0

You keep using terms you don’t understand. It isn’t accelerating. It has no measurable non gravitational acceleration yet. You are thinking of Oumuamua.

They haven’t been withheld. Most can’t obtain usable pictures. They are made to look down at a very bright surface of mars not up at a faint fast moving object in space. They have small apertures and short exposures.

If you don’t understand a topic don’t blindly trust ai slop to give you facts.

Who exactly are you claiming hasn’t released anything? Name names.

There is a huge amount of data freely available.

Loeb latest: β€œIf 3I/ATLAS is a massive mothership, it will likely continue along its original gravitational path and ultimately exit the Solar system.”

Getting his excuses in early. Even if moves like a comet and leaves the solar system it’s still aliens.

If/when the next recession comes how do you think Trump by his own admission being focussed on his gold plated monstrosity vanity project will be viewed?

You'll be shocked to know it already has a crank comment which has nothing to do with the topic.

Just imagine how this will look if there is a recession.

Can’t help but feel that Trump focussing on his golden monstrosity will not be a great look politically if there is a recession, or a stock market crash…

What does non-cometary motion even mean? That’s word salad.

Its β€œorbit” is completely described by its initial trajectory and the gravity of the Sun.

Lol. So you have nothing. Im shocked.

I explicitly did read the peer reviewed papers, that is what the video is about. None of them describe anything that isn’t explained by this being a comet.
