I cast set theory?

Adalast,

I was thinking the same thing.

768,

Thanks.

Pluto and Charon are double planets. Change my mind.

Animated_beans,

Pluto is smaller than Earth’s moon. Should our moon be a planet too?

andthenthreemore,

Gaia and Selene are double planets. Change my mind.

Does our moon independently orbit the sun?

Pegajace, (edited )

No, because absolute size is not what makes a moon a moon. Our Moon is a moon because it directly orbits a planet, not a star. Charon is massive enough relative to Pluto that the former does not directly orbit the latter, but instead they both orbit a common barycenter located between them, making them a binary planetary system.

DroneRights,

A binary dwarf planetary system

Frozengyro,

I mean the earth and moon do the same thing, just on a much smaller scale.

Zellith, (edited )

The barycenter between earth and the moon is within the earths crust. The barycenter between charon and pluto is outside of plutos surface. For those who dont understand, this means that the center of gravity between the earth and moon is INSIDE the earth. So the moon orbits a point within the earth. Not so with the charon pluto system. Both worlds orbit a point in space.

If the moon was to have its own orbital path around the sun, then sure. It would be a planet imo. It's rounded by its own gravity... and it would orbit the sun.

But I guess if we want to the meat of the subject about what defines a planet in the most basic sense, it would be things that make Earth a planet, since we pretty much all agree Earth is a planet. So.. rounded... Orbits the sun... What else would you say describes the Earth?

I thought it was Euler that did this. But I can imagine Gauss doing it too.

mexicancartel,

Ahh because Euler did everything

Yes, this is how I relate to bees.

“I can’t survive above 38.0 C for very long as well.”

OP must be weak. I had a fever above 38.0 °C for over a week once. Finally went to the hospital and my fever was gone by the time I arrived. Our bodies do some weird sh*t sometimes.

This comment section is better than the post itself.

The best use of this meme format in years.

Thats some high quality shit here.

Understood from that post even more than from my biology class.

jol, to science_memes in aLiEnS!!1

Actually I was listening to a podcast that explains this. They didn’t have levers yet. They did have other devices but no lever.

nohaybanda,

I think the lever here is a stand-in for mechanical advantage. I don’t believe anyone is seriously proposing they lifted the blocks with a very long stick.

GreenTeaRedFlag,

you can’t just not have levers.

intensely_human,

It was before levers

jol,

Lol of course you can. They were invented at one point. And before that point… You didn’t have them. I recommend: Let’s Learn Everything episode 49: Goosebumps, (Not) Alien Pyramids, and Nessie & Cryptids.

What’s wrong with that? The yeasts are being baked after all…

I find the H option (from the float package iirc) to work much better than h! for my needs. The picture will still end up on the next page if it doesn’t fit in the current one, but it won’t fill the rest of the page with the text I wanted after the picture and mess everything up

GBU_28, to science_memes in aLiEnS!!1

It’s fair to imagine the challenges a building team would face 2k plus years ago.

Like in this example, building levers that are strong enough to lift the load. I bet they broke a bunch of stuff.

But eventually they figured it out, via trial and error. Levers, ramps, etc. They probably couldn’t describe why those things were inherently the best way, but more approached from the “we tried 9 other ways and they suck. This is the best way.”

Next, the phrase “any sufficiently advanced technology is indistinguishable from magic” is relevant here, but in a backwards way.

Since we struggle to imagine what it would take for an ancient society to master the techniques to build these things, we therefore begin to grasp for unrealistic conclusions (magic…read…aliens).

Same goes for Europeans building cathedrals and stuff, the trick is the history, the methods and the results were more documented and understood.

There are some racism concerns that I think go beyond and around what I’ve discussed, which is more abstract. I’m not discounting the other topics, just not covering them here.

IHadTwoCows,

One thing is for sure: you can’t leverage those stones with a primed FJ 1x6 from Lowe’s. I’ll bet they went through quite a few of those!

NattyNatty2x4,

Lowe’s definitely made lots of USD getting the pharaohs to think the pyramids were a good idea

intensely_human,

Now what were you thinking about a backsplash here?

li10, to science_memes in aLiEnS!!1

For some reason people seem to think they’re fundamentally smarter than people were back then.

Yeah, you may have technically had a better education, but you’re not inherently more intelligent than the average person back then, and a genius from that time is still miles ahead of you.

intensely_human,

I don’t know about that. Intelligence is attractive and it’s a predictor of lifetime success.

charlytune,

I probably didn’t have as good an education as the highest educated classes in most ancient Egyptian dynasties.

Yeah, it’s been linked to systemic racist thought patterns (which are often unintentional but should be acknowledged). I explain it to people like this: take a handful of sand and turn your fist so that your palm faces perpendicular to the ground. Now release the sand slowly… What shape does it form? It isn’t rocket science.

CaptnNMorgan,

So you’re saying the pyramids are just giant rocks piled on top of each other?

If so, then what was dropping them and how could the intricacies inside the pyramids be possible if they were just dropped on top of each other?

fossilesque, (edited )
@fossilesque@mander.xyz avatar

Pyramids = basic engineering shape for a sturdy structure. Wide base, tapered top. A lot of early monumental structures were constructed with that basic concept in mind.

CaptnNMorgan, (edited )

I don’t think people have ever been blown away from the shape of them.

Edit: and it’s actually really silly to think about someone who would be… “Woah! How are those things triangles???” Like what?

teichflamme,

Mind blown

I was thinking “three ridges” first 😅 (I imagined the sand running between the four fingers of my semi-closed fist)
