Our friends at MinuteEarth just released a new book! To check out “How Did Whales Get So Big?” head to: www.minuteearth.com/books/
why do I find it so amusing that minute earth, a RUclips channel, is sponsoring scishow, another youtube channel lol. BOTH channels that ive been watching for YEARs (well the original channels)
It's likely not minute earth buying the commercial but their book publisher.
@@swedmiroswedmiro1352 Hank literally said, "Thanks to our friends at minute earth for supporting this episode of Scishow!" Nothing about the publisher, bro.
Science channels helping each other out
@@recklessrecluse9123 Trust me...That is how it works. The publisher does the distribution and the marketing. Same as in the music industry and in the video game shows industry. I have worked in the creative industry sphere with marketing.
@@swedmiroswedmiro1352 Scishow videos in the past have been sponsored by minute earth, even before this book was released. Explain to me that...
And we always thought that Regolith was just the younger brother of Siriuth.
Oh no you didn't
I don’t understand
Is this book also available in Dutch?
You can't be siriuth...
@@uhohhotdog Check your Harry Potter, specifically The Half Blood Prince.
I love the thumbnail: "8 months, 5 weeks, 6 days." Or, in metric, 9 months 13 days.
I just think it's crazy they were able to keep the cheese samples from spoiling all this time.
Short answer I learned today from a big data scientist: "raw data is sexy" 😂
But for real what he meant by that is propably the best answer you can give: it's always best to have a sample where you can start from scratch and didn't yet scrap anything or affected future measurements.
also first principles.
…not to be crass but…isn’t that basically what happened to some of the moon samples? An intern… 👉🏼👌🏼 on them for the sake of “cool story bro.”
Which. I’m not even in NASA but I’m still mad about that. (Or if that story’s false I’m mad at the person who referenced it on my feed ‘cause they were feeling horny.)
perfect timing, George Jetson will be being born soon (Aug 27th 2022), excellent time to review moon rocks!
It’s weird going from being young enough about dreaming about going to the moon to being old enough to buy moon topic merch for a kid that I have.
Old bosses gran moved to dubbo by bullock train from sydney she watched the moon landing on TV in her lounge room.
I worked with man who dated a girl on the farm that was where my childhood townhouse was, 10kms from 2 Oz Satellite cities.
I taped songs off the radio, ran home to watch star trek before VCR was a thing as a kid, this is youtube.
Two credits to Gene Cernan in this video (don't get me wrong, he's a great astronaut), but with him was Harrison Schmidt, an actual GEOLOGIST! He was selecting sample sites and specimens. Apollo 17 was fantastically productive and successful, but by BOTH astronauts on the surface.
(not forgetting Ron Evans up in the CSM)
Smiles
Unfortunately, Schmitt turned out to be a nutjob who doesn't believe in planetary science when it contradicts his political views, preferring conspiracy theories instead. He may have done an excellent job on the Moon, but he has permanently ruined his reputation as a geologist.
If only we could have sent Eugene Shoemaker. Well... we did, but not as an astronaut. He was such a large part of lunar research, including training Apollo astronauts and even being a candidate himself until he was diagnosed with Addison's disease, that NASA honored him by placing a specially-designed capsule containing a portion of his ashes onto the Lunar Prospector probe, which was directed to impact in Shoemaker crater (primarily for scientific purposes - it's near the lunar south pole, with permanent shadow where there may have been deposits of water ice - but I wouldn't be surprised if it was also chosen partly for sentimental reasons). He is the *only human being to have his remains resting on another celestial body.*
A better alternative to animal testing is sick people dying. Mad science experiments are far worse than any disease.
@@louisfalcone5494 wrong thread.
We're discussing Harrison Schmidt.
If you have a hobby horse, start your own thread...
@@BMrider75 Science is about torturing animals.

'Dumbest comment on the Internet' prize! "
Well done!

Minute Earth Sci show crossover?
"The moon is way dryer than Earth, but the picture is muddier than it used to be." Because there's more water in the soil, and the soil would therefore be muddier. I see what you did there. Well played.

Hello mr funniest at the party
Wait wait wait! Someone stole Moonrocks? I think that is a story you should have delved in deeper :D
Some hippies in the 70s probably mistook them for drugs, lmfao
@@JohnGardnerAlhadis i'm smokin on some moon rocks right now
@@JohnGardnerAlhadis Man now I want to smoke moon rock
@@mrnice4434 We all want to smoke moon rocks.
No… if this version has any validity… an intern or scientist stole them then had sex on them
Also, I expect that at some point more samples will be brought back, so there's no point in holding onto the current samples forever... the moon isn't going to disappear on us tomorrow.
Don't jinx it.
No one imagined 50 years ago that we'd go this long without going back to the moon. Assumptions are dangerous.
Yes there is a point in keeping them. It costs 100’s of millions of dollars to get new ones
@@cutthroat795 If you did a moon mission with the sole purpose of getting samples, yes.
You can be assured that the next time someone goes to the moon and back, they'll have a long list of things to do and bring up or back - and then we'll have fresh samples.
Samples that are never used are aforementioned hundreds of millions wasted.
@@Steamrick that’s not true. Didn’t you pay attention to anything in the video? New techniques and technology can allow us to learn things we can’t right now. Just like the tomographic x-ray imaging they used as an example, which was not available in the 60s. It’s not a waste of money if they get new information out of it, is it now? And there’s no way of getting more samples without the hundreds of millions being spent, is there? Every space mission has dozens of tasks and that would be one of them. Just because it isn’t the only thing they do, doesn’t mean it costs any less.
>2021
>keeping your sealed moon rock samples in the fridge
A better alternative to animal testing is sick people dying. Its better for sick people to die.
We're also probably closer to getting fresh samples anyway -- it's not like the moon is gone now
It's interesting to think that we're going to do this with Mars too.
the ear is 2085 and we're finally crackin open the mars tube
I was SO confused for the first second. Didn't think I clicked a MinuteEarth video
Hank should had said, things are getting more frosty instead of muddy.
"why open it now?" knowing as much as possible about the moon could possibly change how we do things up there, **and** because if we're going back to the moon, we can just get another sample.
So excited to recommend the book to my students/parents :)

Thanks SciShow… once again you’ve mooned me! 😛
Assuming the constituents of Theia are somewhat proportionally different from that of the proto-earth, I’m wondering if the remnants of Theia can be localized, or were they absorbed and distributed in the earth to the point that they cannot be identified?
Gotta keep 'em mint in package, right?
it really blows my mind that we could have space fairing colonies withing my lifetime
This mans voice
Surely makes me wanna learn an have my full on attention
2:15 - "Lunar Prosepector"? :P Yoo knead a nyoo pruf reeder XD
So cool 👀
Good question
I love minuteearth as much as I do scishow
So interesting
Everybody seems to forget about the nitrogen in "breatheble air". It is as hard or even harder to find it outside of earth compared to oxygen.
@Dan Nguyen breathing pure oxygen damages the lung cells and promotes new vessel formation in the retina. Also there would be some metabolic changes of a too high oxygen concentration (in healthy individualas).
I agree with you that it could be recirculated, even thought no system is 100% efficient, that would greatly reduce the need for new nitrogen. Still, they would have to find a way to top it up eventually for a long term solution.
@Dan Nguyen it would be a nice discussion or a good topic for a science video :)
Some of the samples have been lost?!! How do you just "lose" samples brought back from the moon?
Bureocratic incompetence, accidents(like fires), thieves, etc. Its not something very special - just a water/airtight tube/packet with some moon rocks inside. And its not like gov-ments cares enough about space to guard some space dirt these days.
So have those examples explained why when one of the moon missions launched the launch part of the vehicle after they left the moon and it hit the moon the seismometers they put on the moon heard the moon ring sorta like a bell for hours?
so if this regolith was kept back for future scientists, it seems likely they knew we weren't likely to bring samples back in future?
What I find funny, is that I could have bought pieces of the moon when JFK Space Center was selling them back in the 90's. Now I may never get the chance.
MINT IN BOX!!!!
🤔 the fact that the thumbnail for the video has 5 weeks in the middle with 8 months next to it was more intriguing than the topic of the video to me
A more interesting question to me is how do those 50 year old samples compare to moon samples taken today. We didnt take any samples today (or even recently), but that is a different issue.
wrong. the chinese did last year.
@@NoSTs123 OK, so someone else went. Still could be helpful if they share some of the samples or the research that comes out of it. (the Chinese don't have a great track record in that area, but they are getting better about it when its not weapons)
Considering how long thr moon has been around, 50 years is only a boink in time by geological standards. So not much, since it would have had to be a major event which we would have detected.
@@toomanyopinions8353 The moon is not homogenous. Every new sample is a contribution to science. new discoveries have been made almost every year since the americans landed there.
2:47 Ah yes. When a goose becomes an astronaut.
(Angsa means goose in Indonesian)
I wonder what we are collecting now for future scientists to look at.
Continuous daily logs of what attitude to life was like at the beginning of the climate crisis. "Hey Dave, these guys really had no clue lol"
Also helium-3 is on the moon which is apparently could be user in fusion tech. A moon base should be the next step.
after figuring out how to actually use fusion reactors to generate power.
@@DWal32 and after figuring out how to turn those tiny traces of helium-3 into enough fuel for a reactor. Seems like a bigger task than running a reactor.
You guys need to get involved with #Teamseas!
No they don't, as literally everything team seas is trying is provably ineffective.
@@georgeparkins777 glad you are an expert mr. Nobody
@@georgeparkins777 ya u r right, lets just not do anything at all
.
Hypotheses:
Element 115….
Bob Lazars element 115….
Likely in huge abundance in the form of space junks floating about in low earth orbit like asteroids of the Lynette belt…
Gets collected by the Canadarm and stored in cargo hole of ISS then transferred to space shuttle which plays the part of 18 wheeler in space, gets trucked back to earth, skunk works, then turned into sports models for Bob Lazar to see when he gets to hanger S-4…
As for the navy, I bet have an independent program its own. They are into submersibles and things call tic tac’s.
Your choice. A sports model that resembles a Lamborghini or a boring model that resembles a British mini. They are both equally cool.

Hank the human Segway lol.
I don't have a child but I wish to get them the book anyway xD
Six minutes without a single intake of breath? Is that what it’s like in the vacuum of space? I feel exhausted
Found glass rocks in Sierra Nev Mts, near a small lake. State Ranger said came from lightning. Very cool or should I say hot. 🥵
Could it have been Trinitite from a nuclear test??? It is Nevada.
@@indylockheart3082 though possible, The vast majority of the Sierra Navada mountains are in California
@@Piemasta9000 ahhh. Geography. My mortal enemy. Thanks for clarifying.😁
Flashing time-lapse at 3:37.
Please do a crossover episode with minute Earth!!!!
You misspelled prospector at 2:11.
2:33 Am I just hungry or does that look like a basket of chicken fingers coming out of the fryer?
0:33 Hol' up.
Did they try smoking these *Moon Rocks* tho 🤔🧐???
Just saying what if humidity was introduced into the rocks when they took them out to study 🤔
How many moon samples do we have sealed?
Si las muestras contenían hidrógeno 2 o deuterio creo, con estar en este planeta, atmósfera, tipo de luz, etc creo que se pierde o contamina muestra, no me extrañaría fuera otra de las razones para lo que está haciendo científicos en esta labor, sugerencia.
My question is why dont we just go back?? Or even send a Mars Ranger type thing??
They are going back. Pretty soon too.
Yeah, that was implied but not stated explicitly: they did say we might as well open them now and learn what we can because we're going back soon, leaving off "and can get more".
The biggest thing stopping us from going back sooner has been a combination of a lack of funding, and more modern technology and equipment being more sensitive and needing more protection.
The Chinese have had Yutu-2 on the Moon since 2019
If you consider how everything is from here even if it was a meteorite that landed at one point, human-extracted moon rock is literally the rarest thing on Earth.
They knew nobody will care enough to send new moon missions in they future. But how?
Ya know if you combined the moon and Mars mass and accounted for loss, you'd get a planet almost as large as earth...
Yall heard a guy here found a meteorite and washed it with detergent?
*one of the gasses in breathable air
Damn I knew they grabed samples from the moon but over 800 pounds? There would have been strict limits to how much weight they could add for the return trip, seems higher that I'd guess.
the latter missions had quite a lot higher weight allowances, so most of that weight is from those missions.
Is it Minute Earth as in time (minutes), or is it Minute Earth as in size (minute, miniscule or minutiae)?
Time.
A minute or so of talking about the earth.
The size adjective has the emphasis on the second syllable (my-NOOT).
@@michaelmicek thanks you for clarifying. It almost seemed like it was a book explaining the minute (my-noot) details of everything happening on Earth. Enunciation is just as important as is pronunciation.
We will be able to get more samples soon anyways.
Have they tried soaking o e rock in water?
I actually have a few grams of that moon soil
Any news on how many scientists suicided with two shots to the back of the head after studying first sample in 2019?
Uhh... we never went to the moon.. wake up
Whales got so big because they invested early and then accumulated.
was really hoping he'd say, "... and that's when they sneezed on it." lol
"Way drier than Earth" isn't a very high bar! :)
So America wanted to beat China in their findings about the Moon??? 😂
It's not Wensleydale, Gromit, sorry :P
Still sealed under moon vacuum.
MinuteEarth as an Advertiser? what, okay.
Shame you didn't also include the findings of these studies.
Clearly the studies are ongoing given the video wording.
Wouldn't hydrogen just leak out after awhile? So 20+ years there shouldn't be any trace amounts of hydrogen unless bonded to something else.
are you referring to hydrogen inside water which also might be inside moon rock?
*reads title*"because we want moon samples, not degraded elements that used to be moon samples? "
how do they expect to get usable quantities of water from moon rocks when its many times dryer than the dryest desert on earth and we cant pull usable amounts of water out of that?
How the hell do you STEAL MOONROCKS EXCUSE ME?
you pick it up and go away
Why dont we go back to the moon?
Plot twist: Covid-19 was from these samples
I wonder if it's real
If the ISS orbit at a very fast speed, why isn't gravity simulated with that speed?
I feel a G force when I accelerate my car, but why not people in the ISS?
They're not accelerating, they're moving at a more or less constant angular velocity. Hence it's more like a car going a constant speed down the highway. There's no forwards or backwards force acting on them along the direction of travel... Or indeed on any other direction.
Earth's gravity (and the gravity of every mass in and around the space capsule) is still detectable but fairly negligible, hence we call this condition more properly "microgravity."
And at that radius so called centrifugal force is neglible as well.
@@georgeparkins777 Ah, Thanks You!
I confused centrifugal force with angular velocity. Physic is hard to me. It's now obvious to me that gravity can't be simulated by using velocity.
@@georgeparkins777 They definitely are accelerating. And on the ISS Earth's gravity would still be quite noticable. (~90% of Earth's) The reason it seems like those are both false is because it's basically "falling" endlessly around the earth.
@@Ascend777 George's comment is incorrect. A better analogy would be a falling. As you're falling you feel like you're weightless, even though you're very much accelerating due to gravity.
@@Ascend777 acceleration is change of velocity, not speed
velocity is vector, so it can change its direction, and in an orbit the satellite is always changing it while in rotation, but the orbit is just too big to be felt
so speed is the same, velocity isnt

Well it's self-explanatory why "Moon" is dry.... How can they fake a landing in a wet desert if we have only dry deserts on earth? So director just used a typical desert which is dry........

So you're telling me the documentary "For All Mankind," brought to us by the totally not evil Apple Inc, has lied to me?!
in what way?
Why on Earth would Apple, one of the most powerful companies on the planet, have the incentive to lie to its consumers?
@@thekingoffailure9967 Teehee.
@@NoSTs123 I just realized that there was a documentary about the Apollo missions in addition to the alternate history drama sprinkled with moon intercourse and terrestrial intercourse available on Apple TV that my sarcastic comment was referencing I guess it didn't "land."
We never went so how do we get the samples is the real question here
Because people are stupid and think it will be worth a $1,000,000,000, but it's worth $0
Why on earth do you think its we? Like they would ever include us in the knowledge they find. Its them and then theres us.. but no we
Why did one of the moon rocks that was given to the Netherlands turn out to be a piece of petrified wood?
It's unclear exactly why this happened. But apparently, reading Wikipedia, our (US) ambassador to the Netherlands gave a Dutch politician of his acquaintance a piece of petrified wood that he claimed was a moon rock, on the occasion of three astronauts making a diplomatic visit to the Dutch government.
It was by all accounts a personal gift from one man to another, accompanied with what seems to be a bald-faced lie, and only later did the Dutch government acquire the rock and make something of it. The rock, being a rather large fossil, has been valued at about $70USD, and at one time it was insured for something like $500,000
Hey, what's Minute Earth up to these days?
I kinda stopped watching after their inteligence-insulting video about nuclear bombs. Not that the content was bad, but:
I have "vertical" screen usually filled with two horizontal browser windows (I like to watch in one and read in the other), into which RUclips puts a vertical stripe with, in that case a horizontal video (because #short, which quickly became undistinguishable from #unsubcribe), and then they put a vertical "nuclear strike video" into that. Made me remember that scary day when RUclips introduced 144p. Never thought there could be a lower resolution thing on my monitor than that...
Samples? From the moon we never landed on?
:30 "moon soil, also known as regolith." Technically soil is something we only find on earth and is a mixture of dirt and decayed biomaterial. If you dig below the soil, or are in an area low in soil, then you hit the regolith aka normal dirt. So he should've said moon dirt aka regolith
So...is the moon creepy, or is it wet?
Fine yes seal all foreign particles rocks etc. They can contain viruses .and yes be activated with the right frequencies.
Creating an artificial moon doesn't to hard just gather some material in orbit and help gravity take it's course that would restart marshes core better then a reactor
Did...did you just had a stroke typing this?
We all know where most of those samples went. You know. Those rocks make great portal surfaces.
It all became public knowledge, what, 11 years ago?
You get it?

Fine. Go play Portal 2.
