He was talking about seed oils and sugar and their prevalence in our grocery stores, and the verifiable damage they do and the reason for the subsidies. No pizza mentioned.

How about the U.S. stealing Madura's Airplane and taking it to Florida! Did our new president sign off on this or did the old one who's still president? Or was it the edict of one of many spy organizations that aren't accountable and have no allegiance to any cause? Watch it become a non-story:

Sure enough. This unprecedented act of aggression towards Venezuela has been avoided by the msm.
It's nothing. Imagine if they had taken our President's plane. This is bullying. The term "sanctions" is a broad excuse for anti-social behavior.

As Harris keeps leaning rightward, Trump is making left-sounding gestures, like more abortion time frame; legal pot; environmental sympathy via his embrace of 'Bobby', whom believes in climate change and science in general.

We have all seen these. I hate them just because of the click-bait nature:


Nasa issues alert for stadium-sized asteroid approaching Earth tomorrow


I won't bother reading the article, because I'm sure we all know the general outline of the contents. "A really big rock is going to come somwwhere within a million miles of Earth tomorrow. Nasa knows exactly where it is and where it's going, and there is zero percent chance it will hit anything, now or in the next thousand years."

But since you're herr.....could you clock on this ad for Lithuanian women looking for husbands?

What bugs me about these articles is the use of "alert". Nasa hasn't issued any alert, by any meaningful definition of the term, for whaterver this object is. They have it in their database. That's it. Maybe they have some list where they say "Big rock passing Earth today", so that amateur telescope enthusiats can point in the hopes of catching it in their 'scopes/

Disappointing The Independent has exactly that headline - they're often pretty reliable.

Much more interesting piece hidden away:

Later in the month, a smaller asteroid will become a temporary “mini moon” as it is pulled into orbit around Earth for two months.

The 2024 PT5 asteroid measures only 10 metres across, according to a new study published in the scientific journal Research Notes of the AAS, and once formed part of the Moon.

It will remain within Earth’s orbit from 29 September until 25 November, according to the study.

Now, that's cool.

"Later in the month, a smaller asteroid will become a temporary “mini moon” as it is pulled into orbit around Earth for two months."

Just wondering if that is an exact quote?

If so, it's at best poorly written. It deserves far more explanation as to how something that starts orbiting the Earth can, after two months suddenly de-orbit.

It gets bored?

It's actually not wrong, though - it's how the subbie of that piece put it and it works for me.

I wouldn't be able to repeat the mathematis today, but a few years ago I took an oline class from Coursera in spacecraft operations, that included orbital mechanics. Basically, there are eliptical orbits, and there are hyperbolic "orbits". I put the "orbits" in quotes, because they don't usually involve multiple revolutions around the planet/moon/object or whatever larger rock has captured them. An elliptical orbit is stable. Once it's there, it's there for good, barring interference from a third body. However, hyperbolic orbits are not. They go around the planet and then get flung into space again.

It's the same principle that's used when you hear about a "gravitational slingshot", where a space probe might travel to Venus and go around it to pick up speed so it can head out to Jupiter. It "goes into orbit" at Venus, but it's not a stable orbit. It flings it out toward Jupiter. They way it is usually described is a bit misleading, because it implies that the spacecraft picks up speed as it goes around Venus. It doesn't. However, its velocity changes, so that some of the kinetic energy that was carrying it around the sun at a certain speed, will now be sending it out into space. Of course this is all quite predictable so the folks at NASA or JPL or whoever figure out exactly where to approach Venus so that the spacecraft's orbit around the sun becomes a trajectory toward Jupiter or wherever the probe is aimed at.

In the case of the asteroid, it's just doing that naturally. It's being captured, but in a hyperbolic orbit that will fling it away naturally.

fine explanation.

(if not hyperbolic)

The headline i'm waiting for:

Did Diddy did it, or did Diddy didn't did it?
