- Earth's thick crust might one of the reasons our planet can support life. But scientists are looking for something a little more brittle.

On Venus, You're Walking on Eggshells" On the Sun, you're walking on sunshine (Whoa!) And don't it feel good?
OW OW OW HOT HOT PFOO PFOO PFOO IT BURNS!!!!!!!!!
THIS DON'T FEEL GOOD AT ALL!!!!!
Bbvv
@@johnknott5639 well said
And Giant steps are what you take
Walking on the moon
"You might as well be walkin' on the sun"
This is why we bigfoots don't go to Venus, I'm too heavy to walk on eggshells
Human space suits are too small for us anyway. BTW, have you seen Wendigo? He borrowed my 10mm socket, and hasn't returned it.
Earth may have been an eggshell planet early on since modern plate tectonics started only recently, geologically speaking, when the interior became cool and thick enough for the edges of plates to start sinking. I read it could have been the reason behind "The Boring Billion".
Interesting insight! didnt even know plate tectonics were geologically recent lol. can you please give the link of what you read? or say where you found it? :)))
Scishow eon had taught you well :).
@@ingegaugerlarranaga4210 Search for a scientific paper by the AGU titled "Enigmatic Mid-Proterozoic Orogens: Hot, Thin, and Low".
@@ingegaugerlarranaga4210 The timing of the origin of plate tectonics on Earth is a bit more controversial as while it is pretty clear that tectonics were different prior to the Neoproterozoic based on the types of minerals formed and chemical isotopes etc. what those differences actually looked like is a much more difficult question to answer. There does seem to be evidence for something like plate tectonics but if it was plate tectonics it was a much more shallow process so it does lend support for Earth's crust being far more shallow/thin than it is today. In fact prior to 3 billion years ago there is some evidence to suggest Earth didn't have any terrestrial continents though given the ongoing processes in the mantle related to mineral hydrate formation and the relationship with temperature this may have been due to Earth's oceans having been far deeper back then.
Their are interesting implications on the sea levels and state of tectonics towards the development of life on Earth and the evidence is scarce since it was so long ago in time so naturally this will likely remain a hotly debated subject for a while as that is typically how these issues go short of a clear evidence in one way or another.
On Mother Venus, you don’t crush pebbles. Pebbles crush you.
“Call before you dig” hits different when in an eggshell planet.
Not horrific Hawaiian pronunciation! Nice work.
Yeah, he did pretty well. Maybe next time they'll use ʻokina instead of apostrophes.
@@KeithKessler If it's anything like the graphics I sometimes do, the Hawaiian alphabet isn't an install option. 😕
Very interesting take on Venus and could potentially help to explain its relatively young surface.
"Older, cooler, smaller rocky planets are likely to have very thick lithospheres."
So...Mars?
Mars tried to be cooler.
And it froze all the way through.
Now it's a dead cold rock.
Never try to be cooler.
You're perfect the way you are.
@@askani21 I know this was just meant as humor but...the Insight lander has definitively proven that Mars does still have a hot molten iron core, but its crust and mantle are too thick and rigid to let much volcanic activity occur on the surface (though there are signs a few volcanoes on Mars COULD erupt again at some point), and the core is too saturated with impurities like sulfur and oxygen to be able to generate a dynamo.
@@AceSpadeThePikachu Oh really? That's interesting. So our lovely neighbor isn't completely dead after all :) Thanks!
The phrase "space potato" is awesome and descriptive.
We are already walking on lot of eggshells here on earth.
家語は世界、それです。
"I'm walking on EGGSHELLS, YEAHEAHEAH"
i like that they put the whole script in words to shows so that you can understand the video with turning off the sound
"walking on eggshells"
Sounds like my house
Do what I did, and take up tap dancing in wooden clogs. Walking on eggshells is much more enjoyable once you've reduced them to a fine, powdery dust.
@@SkunkApe407 this analogy is getting deep
@@BigyetiTechnologies don't worry, I have an extra pair of bib waders for ya! I wasn't a Scout, but I'm always prepared for anything. Adapt and survive, bud.
RIP Arecibo you will be missed.
I actually shed tears over hearing its accidental destruction.
I think this episode was worth watching, just to hear Hank say "space potato" multiple times. ;-)
It's the cutest little space stalker.
I've been wanting a model done of how the moon effects plate tectonics. For example does just having a thicker crust guarantee plate tectonics or do you need that gravitational tug, like in tides.
Tectonics move with the movement of magma, in geological scales the moons tug is basically uniform so I don't think it affects it
Pretty cool info! LOL @ space potato, too! 😄 Thanks for what you do, Scissors!
I love Fridays… and Tuesdays, but Fridays are the best.
A goddess on a mountain top

Do we know how old the "quasi-moon" is yet? Is there any chance it's a remanent from the clash that created Luna?
This doesn’t have anything to do with this episode but I have a question and hoping one of you might have an answer for me or somewhere to get info. So with rising oceans, how much can be contributed to draining underground water reserves and adding that to the environment? I get it probably wouldn’t be much but still curious on that since so many countries are using up there underground water. Thx have a great thanksgiving
Just going from memory (so take it with a grain of salt), but aquifers already dump water into the oceans as part of their normal flow, so pulling that water to the surface is going to have a miniscule effect on the whole sea level issue, if any. Overuse of aquifers is a serious issue, but not to rising sea levels.
Hope this helps.
Probably not much. It's a good question. It's true that humans in dry areas have tapped aquifers faster than they're replenished by rain, which comes from the oceans. But it's also true that the warmer the planet, the more other areas on the planet get rain. It's probably more of a relocation issue: Some aquifers get depleted while other bodies and reservoirs of liquid water grow. Still, the whole world's liquid fresh water is small compared to the solid cap on the south pole. That will be the main contributor to sea level rise by far. The ice atop Greenland would be next down somewhere. A small drift of True North and the spin axis of our planet has already been attributed to the mass redistribution from Greenland.
Not that much. Fresh water is a minuscule part of earth's water.
Of more relevant concern would be the subsidence of the land over the aquifers and the intrusion of brackish water into them.
Compared to what others might say to you, I would say the opposite, It have a huge Impact but because of different reason.
Our Land "Floats" above the aquifer for example the island of Java, or more spesifically Jakarta city.
They used up a lot of ground water aquifer and cause the land to sink, and with increasing sea level this create a compounding problem.
The land keep sinking and the ocean keep rising(which create a suction that cause ground water to move towards the ocean because salinity, also make the ground water contaminated with sea water.)
They shoulda named the quasi satellite Quasimoono.
Space Potato is my new favorite term for space objects
03:45 Whoa! You've nailed the pronunciation of Kamoʻoalewa! I'm impressed, I live in Hawai'i and am used to both the proper pronunciation and the mispronunciation of various Hawaiian names and words! Kudos to ye, brah!
LOL, I spoke a bit soon, towards the end of this section, ye started to slide towards the haole style of pronunciation, but at least ye manage to largely retain the ʻokina in yer pronunciation. Still, good job, I realize yer started moving closer to yer normal speech cadence towards the end and it IS rather dificult to say Hawaiian at that speed, LOL! 😆
The 'okina - that's the ' that means there's a brief stop in the pronunciation?
@@PyroDesu Yup, basically the glottal stop sound in between the syllables of "uhʻoh."
@@TheGhostGuitars Cool. I'm nowhere near Hawaiian but it's always bugged me when that's omitted. Seems disrespectful to the original language. Accent marks I can kinda understand - those aren't "normal" symbols on keyboards (though they ought to be used in professionally-made texts) - but the 'okina is just a single quote mark, perfectly normal.
(I'm in a field where we occasionally talk about stuff like 'a'a lava.)
@@PyroDesu The ʻokina is actually a ʻ and not a ' (it curves down, not to left). Fortunately, I have the Hawaiian keyboard downloaded into my virtual keys. TBH, I have no idea how to get it on a hard keys, LOL! What I did was make a Google keep note document that contained all of the special characters I use often and make it available to myself when on desk/laptop. Alternatively I just write the document on my phone then save it onto the Google Keep Note pad then access it on desktop/laptop and finish up the job as needed. 😉😁👍
@@PyroDesu ʻaʻa vs pahoehoe lava, eh? Sounds like yer in the geology or vulcanology related field. Cool and kudos to ye then!
LOL, I know what ye mean, tis annoying that Google search writes ʻaʻa as aa. Even worse when Translates says it as aaaah, instead of a-a (with a sharp stop before each short "a" sound).
I'm looking forward to Astronomer's developing more and better ways of sensing different aspects of exoplanets so we can learn more about these other worlds. It's a very interesting field of study and discovery. Back in the day, I took a planetary geology course one summer that was taught by a professor who was part of the NASA team studying the lunar rock samples brought back by the Apollo missions of the 70's.
I have a hunch about this quasi-satellite.
As it turns out, we have our very own Minmus!
Space potato 😂
Edit: I'm in tears. I'm Puerto Rican and my fondest memories are in the Arecibo Observatory. Thanks for immortalizing it with a pin.
Today has been such a beautiful day. An eclipse in a clear night sky, my first sighting of a shooting star and now this.
To all who get it, thanks for buying it. 🤗 I'm so incredibly emotional rn 😭
Grácias!
You always have GoldenEye.
@@SkunkApe407 For England James?
@@Johnny-rx4hs for England.
I like to think that Earth has some Stuffed Crust goin on.
No one:
Scientist: Lets find all the THICKKK planets
How did I just discover SciShow Space!
It might have been a while since I've watched a video. The new intro looks great.
Wow.. i've never been here so soon before.
Omg same. What an honor
Kamo'oalewa may be a leftover from the moon's formation.
New name for new astronomical object - "Space potato"
Venus: The real life Nether
Lol
Be careful with that pin, because it might break!
the Earth's dark twin
"but you have to hurry, the pin is only available in november..."
People in november 2022: sweet!
Gimme space potato. I hungry.
Hank has nice hair, I'm jealous
I noticed that. Has he had a haircut? Or does SciShow now have an off set makeup and hairdressing department? Or both?
We gotta find that Space Chicken then.
0:46 wow, imagine identifying _planets_ in the _world_
That quasi satellite is going to be the first thing that humans mine in space for resources....
Imagine all planets are just massive eggs, hatching into some cosmic beast when the sun bloats.
telescopes not really able to get surface features from our planets too, hence the missions
A great S³ video! Love your work! I'd love a deep-dive on current evidence for 'earth-like' exoplanets and 'sol-like' star systems please.
Check out Crash Course, a sister channel to SciShow (done by the same overall company). They have Crash Course Astronomy, and it might go into this.
Decent Hawai'ian pronunciation, man! Aloha!! 🤙🏽
They should've named the quasimoon spudnik
All hail the space potato.
Get it together, Venus.. sheesh.
Orbit the Earth like an "actual moon"? Not only does the Moon's orbit never cross itself, it is also always curved towards the Sun. This asteroid seems to share similar characteristics at a greater distance.
Dang, thought you were going to reveal that Venus is actually a giant space whale egg.
I’d still be on the lookout for Voidspawns.
'New Moon, Quasi Moon, Half Moon, Full Moon.' (Pretty sure that's how it goes....maybe the other way round.)
I vouch for classifying all quasi moons space potatoes from here on out.
"Earth has had other quasi-satellites before, but they tend to come and go."
And they never call, they never write... is it too much to ask for a lousy postcard?!
The intergalactic postal service sucks. I've been waiting on a package from Alpha Centauri for millenia.
Aaayy, kudos for pronouncing kamo'oalewa correctly
Reminder: we are also living on an "eggshell" because average Earth crust thickness is only 40km, while it takes another 6.370 km to reach the center of Earth
(PSA for us Murican's, swap the role of the decimal and comma, so "6,370km" or just "6370km")
*edit:* also 6370km≈3960mi and 40km≈25mi. Basically, they are saying: Earth thick, crust thin :P
“You might as well be walking on the sun.”
I read recently that the Moon has it's own quasi-moon.
I wonder if would be easier to peel Venus's eggshell than the last of boiled eggs I made. Why are some so difficult to shell, and other easier?
WE FIND THE ANSWER TO THIS, AND WE FIND THE ANSWER TO LIFE ITSELF, MY FRIEND.
Cooked too long, did not cool off long enough
Older eggs are easier to peel than fresh eggs. Also, don't overcook them and cooling them quickly will help. Tap the pointy end so it cracks and put back into the cold water and wait a few minutes for them to cool. Change the water when it gets warm. Cool for twenty minuets or longer for best results. Personally I don't boil my eggs anymore. I steam them in a steamer for 7 minuets and cool them in an ice bath in the sink. I like my yolks still runny and the whites barely cooked. 8 minuets of steaming makes the yolk more solid and 9 the yolk is solid but still soft. At 10 the yolk is hard and uninviting to eat. The yolk will get a green crust if cooled too slowly. This is just sulfur and is okay to eat.
Sorry to write a book, I just really like eggs.
@@cillyhoney1892 in my experience, fresh eggs from my own chickens are way easier to peel then the supermarket eggs. I would also say that 20 minutes of cooling is very unnecessary. Just put it half a minute in cold water, and peel it while it's in the cold water. Never have problems with it doing it that way.
Quick cooling to "shrink' inner part quickly (overcome attachment... works for relationships too - cold water on ex guarantee result) - cold water two-three times (1st time it might feel cold-ish but there is still good amount of heat inside egg that will minimize shrinking) and mostly are easy to peel.
On Venus, you're not walking.
Space spuds!
I think on venus YOU are the eggshell lol
Venus is the best plant change my mind
it do eat flies
It's native only to a 60 mile meteor crater. Pretty sus.
Plant? Lol
Te he! Planets "leaking gas"! Planet Sized farts!
On Venus, you're not walking at all. You are, however, being instantly crushed and vaporized.
WE HAVE TWO F*****G MOONS!
Wasn't there at least one icy moon or so that fit the picture of an eggshell planet pretty closely, except with a "lithosphere" made from water?
I thought a Quasi-Moon lived in a bell tower and played drums.
Should we start calling "the Moon" Luna?
"Luna" ticks all my boxes
I'm thinking only people who speak English call it the moon, also pretty sure that goes for the word earth as well.
Man wouldnt it be wild if the quasi moon was a left over chunk of thea or smth
Is next month's pin gonna be Arecebo, but crashed? That would be lols.
A potato flew around my moon before you came-
I didn’t even realize there were eggs on Venus? 🤔
Hi
Suo
Maybe that quasi-moon came from Earth.
Ding ding ding
How did eggs even get on Venus!?
Act fast! The Arecibo Radio Telescope won't last forever!
Any one else thinking outerwilds and brittle hollow?
Who designed that pin?
How does this research apply to eyeball planets?
Based on its name I’m guessing the space potato comes from Hawaii.
Could Kamo'Oalewa be a Thea remnant?
Did somebody say... space potato?
I have some idea's of how yea might be able to get some probes on Venus surface long enough to learn something. It's by far one of the most hostile places in the solar system
Identified planets "in the real world"? Maybe in the real galaxy or universe.
Could the space potato be a piece of Theia?
QUASI
Hank
So Minmus DOES exist! Now we need a Venusian/Cytherean quasi-moon and heat up Europa a bit, and you’ve got a bigger Kerbol system.
Venus has mountains! It's not an eggshell world.
What if it hatched ?
Cthulhu will come
Hey Hank! GREAT job pronouncing Ka-moʻo-a-lewa (the [temporarily] oscillating fragment of the heavens); now it's time to work on writing it correctly. I noticed that in this episode an apostrophe (U+0027) was used to represent the Hawaiian alphabet consonant letter ʻokina (U+02BB). This is technically incorrect and is jarring to someone with knowledge of proper orthography in ʻŌlelo Hawaiʻi.
Your work is always of the very highest quality. In particular, I have noted the care you and your team always take to acknowledge words and place names used by indigenous peoples everywhere, and to say and write them correctly wherever this is possible.
An apostrophe is incorrect where an ʻokina is called for. I feel confident that you'll get it right in future productions now that you have been made aware of this fact.
Thanks again for all the excellent work that comes out of your studios.
It's entirely possible an ʻokina character wasn't available in the font they used, in which case, ` ‘ and ' are considered acceptable substitutions. Hopefully that can be rectified soon enough, though
I suggest you look into the history of "æ" for some perspective on how precious you want to be with the written form of a language whose users borrow an alphabet from their colonizers.
I wonder how critical you would be of pronunciation if the presenter weren't a native white American? Say, a Filipino with a Tagalog accent?
How do you know they have an accent? Because they use English phonemes "wrong."
If native English speakers aren't allowed to be bothered by non-native speakers who pronounce "th" as "t", or "f" as "p", maybe native Polynesian speakers can relax on the glottal stop thing?
Why should speaking Hawaiian with an American accent be any more of an affront that speaking English with a Filipino accent?
Brittle hollow
haven't watched the video, but I hate walking on eggshells, and this is exactly why I don't visit venus.
Can't we give our new celestial neighbour a more simpler name than Kamo'oalewa, like Peter for example? How do you even pronounce Kamo'oalewa?
"Peter" from "petra" ... "rock" 👍
The nice thing about using Latin in science is that there aren't any native Latin speakers to get bent out of shape when people with other phoneme traditions approximate pronunciation
Is Kamoʻoalewa an Alien probe? Hmm? X•D
Lets hope it's not after whales because we are running out of those :S
@@EVG_Channel that's okay, I speak whale. No need for any time traveling Vulcans. X•D
Why aren't there more "moons" at the lagrange points of planets?
Possibly because they are unstable in the long term, since they are essentially a balance point.
