QI Compilation | Alan VS The Moon(s)

[@theinternetshavecome1640]

I will never tire of Stephen's laboured, adamant delivery of 'Because it was discovered in 199-****ing-4!'

[@AdmiralBonetoPick]

It was actually discovered in 1986. What they discovered in 1997 was its orbit: and what the QI researchers misunderstood is that it orbits the Sun, not the Earth, so it's not a moon.

Justice for Alan!

[@sorlag110]

Asteroids can be moons no problem. Cruthne _does_ orbit the Earth but is something called a quasi-satellite because it's outside Earth's hill sphere, still technically an orbit. As of writing this we have 2020 CD3 too.

[@thebonesaw..4634]

@@sorlag110 -- *Cruithne does NOT orbit the Earth...* it orbits the sun, and is in a co-orbital pattern with Earth. It crosses only a small segment of Earth's orbit (about three month's worth)... and it comes nowhere near the remaining nine month's worth of Earth's travel around the sun. As such, it's preposterous and utterly disingenuous to even attempt to imply that it "orbits Earth". You might as well also state that Mars, Jupiter, Saturn, Uranus, Neptune and even puny Pluto... also *"orbit Earth".* In fact, it's even more plausible that those bodies orbit Earth because each and every one of them circles Earth's entire orbit of the sun, which is three quarters *MORE* than Cruithne circles.

[@sorlag110]

@@thebonesaw..4634 It's indeed co-orbital, which is a type of orbital relationship. It's not a classical orbit like the moon, but I said it's *technically* an orbit. It's not preposterous or disingenuous, you're being arrogant and incautious in saying that. In fact orbits come in many configurations. The gist of co-orbital ones is that bodies share the configuration. The planets and Pluto is not in co-orbit with Earth. Cruithne's orbit however is *dependent* on Earth. When you think about quarters and months, do know orbits are not defined by quantities but the qualitative relationship of the involved bodies.

[@carson0myers]

@@sorlag110 Cruinthe does not orbit the earth in any sense. A moon is a natural true satellite. The fact that the earth influences Cruinthe's orbit once every few hundred years doesn't make it a true satellite. Quasi-satellites are not moons, and "co-orbital" isn't a type of orbit, it's a relationship between two or more indepenent orbits. Cruinthe traces a neat pattern on the sky over the course of the year; it's cool, but that's not an orbit at all. Cruinthe has a straight-forward elliptical orbit around the sun.

1. Cruithne and its ilk aren't really moons; they're asteroids orbiting the Sun whose orbits are stabilized by Earth's gravity. 2. The current IAU definition of "planet" doesn't require the planet to have evicted every other body in its orbit; it's just that the stuff still stickin around needs to be "controlled" by the planet's gravity, like the Moon or Cruithne.

[@waynehanley72]

BINGO!!!

[@57thorns]

A reasonable definition of a double planet would be that the common center of mass is outside the more massive planet. Jupiter I believe have that distinction relative to the Sun, and Charon relative to the Pluto. So if Pluto were to be reinstated as a planet, there would be 10 planets, as the Moon-Earth system orbits around a point beneath the surface of the Earth.

[@AdmiralBonetoPick]

@@eolsunder Like that Christmas episode where they claimed all sorts of similarities between Jesus and Mithras. In fact their only source was a book by a conspiracy theorist who had misinterpreted a bunch of things to try and prove her theory that a Roman Emperor had invented Jesus in the third century. They claimed "Like Jesus, Mithras was born in a cave of a virgin" - in fact Mithras emerged fully grown from a lump of rock in the myth (which the conspiracy theorist twisted as "the rock that Mithras emerged from would have left behind a crevass or cave"), and the ancient temple in Anatolia which the conspiracy theorist had claimed was dedicated to Mithras's "virgin mother" was actually to his consort. QI claimed Mithras had 12 disciples "like Jesus" - when in fact he had 5 (who were animals, not people) - but the conspiracy theorist author had misinterpreted a sculpture of Mithras surrounded by the zodiac as being disciples... Indeed, in the second edition of her book, the author even admitted she had been mistaken about this zodiac point, and the temple in Anatolia - but QI's researchers were using the first edition even though the second edition had been in print for years. And so on. The author/QI claimed that like Jesus, "Mithras sacrificed himself" (which is wrong: Mithras never died: Mithras famously fought and killed a bull, and the conspiracy theorist argues with no evidence at all that the bull somehow also represented Mithras...).

Not sure how your logics work here, but the whole point is that both celestial bodies had (has) parts of both :p So the Moon has some Earth and the Earth has some Moon. Which means The Earth has two The Moons, which are not moons but binary planets.

[@LEO_M1]

SebSk The logic is that until the second planet collided with the first, there was no “Earth”. The Earth is a byproduct of the collision. Take salt for example. If you have either sodium, or you have chlorine you don’t have salt. Therefor the moon has one Earth.

[@sternis1]

What fascinates me is the fact that someone at Nasa at some point in the 80s went "Well, here's some old tapes, I wonder what's on them? Nah, probably nothing important, we can tape over them". I mean, someone decided to tape over what is arguably the single most important piece of film recorded up until that point (possibly still is). you can literally take any other piece of film in the world, and it would be a smaller loss than that. This is probably the instance of the worst possible decision someone could ever make.

[@Wustenfuchs109]

Well, not really when you think about it. First of all, those were originals, footage has been copied countless times on better mediums since then. It's like with other historical photos - we don't have negatives being kept, we just copy the pictures over and over again in different mediums. The other thing is, those tapes were the ones in the camera on the moon - things shown on the TV were signals received and were copies themselves. And it is quite possible that in the 80's when the ORIGINAL tapes were overwritten that people had a choice - to commission tapes for specialized cameras used on the moon 20 years ago, or simply rewrite over the existing ones that have no scientific value. There was absolutely no reason to keep the original tapes as the footage was copied on better mediums that allowed us to make the whole thing of much better quality (various filters and montages etc.), it didn't have any scientific value in the first place and finding a tape that would fit a 20 year old specialized camera was simply way too expensive. People who use old style film for ordinary cameras know how expensive it is in the day of modern digital cameras, let alone some very special limiter series tapes that work on a single model of camera.

Regarding the "no moon, it's actually a planet" and "the earth orbits the moon too", the center of mass that they both orbit is below the surface of the earth always, so no, it's definitely the moon orbiting the earth and not the other way around.

[@Jasmixd]

Well, technically speaking, isn't saying one body orbits another a simplification? In the end they are both always inside each other's gravitational spheres, moving arround the mutual center of their mass, so what if it happens to be inside one of them?

[@BruceNJeffAreMyFlies]

Everything orbits everything else. It's just simpler to say the earth orbits the sun, and the moon orbits the earth, than saying anything else. The sun does, technically, orbit the earth, but the orbital paths of the rest of the solar system are so much harder to conceptualise as orbiting earth.

[@AnnaAnna-uc2ff]

Sandi's story about the moon landing is priceless.

[@capt.samvimes768]

🤣 Sandi at the end 🤣 I think if the question ever comes up again then answer needs to be "We have no bloody idea!"

[@SeerWalker]

aww that last story was cute

[@CFMichael]

You've missed out my favourite one: How many Earths does the moon have? Rich Hall: Which moon are we talking about?!

[@alastairbrand5821]

So can we ask any conspiracy theorists, "OK, which moon didn't we land on?"

[@asusmctablet9180]

Cruithne isn't a moon. It's a co-orbital asteroid.

Qi is all about r/technicallycorrect. Everything is technical with Qi.

@@stephengnb But it *isn't* "technically correct" to call it a moon of Earth. (Anyway, first they'd have to supply a definition of "Moon" to be "technically (in)correct")

[@sirandrelefaedelinoge]

You're actually QB ... QUITE BORING.

[@Ward1706]

Whoa, Nelly Frutado. This bloke's got a word for everything!

[@hamburgerhelperflick]

Love that story by Sandi at the end

[@momsterzz]

That is so cool to find out where Sandi was during the first moon landing🌛💛

Alan is adorbs 🥰

There is no TH sound in Irish. When you see a H, it means that the letter in front of it is silent. In fact, there used to be no Hs in Irish, right up to the invention of the typewriter. I silent letter used to be indicated by a dot above it but typewriters couldn't print the dot. So, they started indicating a silent letter by putting a H after it.

[@aredbee]

Thanks, that's going to be helpful from here out!

[@floatingstarfish932]

My God, I love QI!

[@Alcagaur1]

At "The Earth orbits the Moon as well" you basically see Alan's brain break.

[@smnio5619]

3 more moons between seasons. Alan was absolutely trolled

[@confectortyrannis275]

that last story was awesome

[@nigeldenning5810]

The actual answer is ONE. The reason for this is as follows: if you draw a line between the (gravitational) centres of the two bodies, if the barycentre (point around which the two bodies rotate) lies in a point in space BETWEEN the two objects, it is considered to be a BINARY PLANET relationship. If however the barycentre is WITHIN either of the two bodies, it is considered an (EXO)PLANET/MOON relationship. In the case of our relationship with the moon, the barycentre is about 1,000 miles beneath our feet, ergo our moon is just that: a moon. Pretty damn conclusive QI - you need better researchers!

[@jelmerterburg3588]

The thing that makes the situation with our Moon rather unique is that it has no retrograde motion: from the Sun's perspective, our Moon orbits the Sun (albeit in a rather wobbly fashion) and not the Earth. I assume that this is the reason why QI mentioned the "binary planet" thing, although they did not bother to explain _why_ the Earth/Moon might possibly fail one of the criteria to be considered planet and moon. For the Pluto/Charon/etc. system, it is much more obvious why one would consider them a binary (dwarf) planet: its barycenter lies in space. But if you look at the relationship between the Sun and Jupiter, the barycenter is not necessarily a deciding factor. (Fortunately, the Sun has that nice distinctive feature of being a star...) That said, the barycenter of the Earth/Moon system lies well beneath the surface of the Earth and the Moon is tidally locked with the Earth (but not vice versa). On top of that, _it's called THE MOON_ :P. That's 3-1 for maintaining the status quo. (I very much doubt that the official classification by the IAU will ever change.)

[@LughSummerson]

Of course, this means they've got a new answer coming soon. Something about the Moon not being formed from ejecta after all.

Alan has a dispute with The Moon(s), Rich has a war with it.

Blue moon, YOU saw ME standing alone. ;)
