- Saturday 20th July 2019 is the 50th anniversary of the Apollo 11 Moon landing #apollo50 #apollo50th #apollo11. Whilst this was one giant leap for mankind, for me it's the scientific legacy of the Apollo missions that are so impressive. So here are 5 things we now know because of the experiments done by the Apollo missions:
00:00 0 Introduction
01:54 - the distance to the Moon
04:08 - the structure inside the Moon
05:51 - what the solar wind is made of
08:43 - what the Moon is made of
12:33 - how the Moon was formed
In particular, all the results from Apollo built up to overhaul our thinking of how the Moon formed.

“Learnt” is British English 😂 I don’t think I’ve ever said it as “learned”.
We always hear about the achievement of the Apollo missions but hardly ever the scientific results that were made possible because of them. How much of the science in this video have you heard before?
none

Learnt is the past perfect tense, used with "have" e g . Have learnt. "Learned" is the past tense, e g "we learned that yesterday."
@@skiptrace1888 when someone tells you that they have used the correct variation for their version of English, please believe them. Read this page from the BBC that explains www.bbc.co.uk/worldservice/learningenglish/radio/specials/1535_questionanswer/page50.shtml
yeah, we americans(or english 2.0 people ;) ) get stupid about those things..like color/colour, tire/tyre etc...who cares...as long as it does not change the extrapolation of the meaning to others...
Your enthusiasm is infectious, well done as always doc
Yeah. All scientist are this charming and marketable. Hello actress!!

Dubay? _Seriously?_ The guy is an idiot, with less than a grade school understanding of how the world works, flerfs have moon rocks in their _heads,_ it's why they're so "spaced out". Give it up flerf boi, you'll not be able to convince any of us "brainwashed sheep" on _these_ videos, we actually _have_ "brains".
@@bryantaylor4071 You take the self-avowed nazi's word for anything?
I always thought of ‘doc’ as applying to ones with a stethoscope, and not the ones with the telescope-I was wrong apparently.
No human ever landed on the Moon.
Congratulations on the award. Well deserved.

She should cunningly fashion a brooch from pure green.
No, wait - she'd look like she'd sneezed.

HAHAHA , love the Adder comment ;)- she is a wise woman!..... 2 things must you know of the wise woman.....1, she is a woman!!!... 2......
How is it that I can watch lots of educational videos about apollo, and Dr. Becky manages to give me more interesting information than the others combined??? Becky, you are a master at selecting the information to be covered at just the right depth!
I don't know, most of us had no problem, education is what you make it.
Always a pleasure listening to you tell us about science stuff's (I'm usually working so you're on a window behind the windows I'm working) .. Keep up the good work, great stuff Dr. Becky .. Lots of Apollo stuff going on, this one was very enjoyable to listen to ..
You got an award for your CZcams Channel. Congratulations!!! Well Deserved.
This may well be the most information-dense and informative science video I've watched on CZcams in the past 12 months (and I watch a lot). Ever since I was enthralled and inspired by the Apollo lunar missions as a boy of 10 (Apollo 8) to 14 (Apollo 17), I've been avidly following developments in manned and unmanned space exploration, astronomy, planetary science, astrophysics and cosmology. This video is great because it pulls different threads together and neatly ties them up into a grand conclusion, and it's all so clearly and compellingly explained.
Dr Becky -- you are a consummate science educator and communicator ... and you're adorable into the bargain. ;-)
Apollo missions also proved beyond a shadow of a doubt that the moon is not made out of cheese.
Cheese!!!
lies, LIES
Yes, but the jury is still out on the 'man in the moon'. He wasn't found but could've just been away on a holiday.
moon is flat
Apollo missions also proved beyond a shadow of a doubt that people will believe anything their media tells them.
Thank you for your channel, Dr. Becky. As someone who was pinned to the TV during the Apollo 11 mission, I can remember how exciting it was. It is good to see you carrying on that enthusiasm for science.
Are we just going to ignore the awesome dinosaur in the background!? Man...poor guy is just sitting there waiting to be acknowledged. I vote for more dinosaur in this space series. Dinosaurs and space are two very cool things and smashing them together will make one totally awesome thing.
Dear Dr Becky I am truly proud of you being British. How good to see such enthusiasm and knowledge on display from one so young . You are truly inspirational. This video is very interesting in that it shows so much that my brother in law as a NASA engineer and scientist was involved in. I always send him your videos and he is very impressed. He came from Hull originally and eventually went to NASA. He was involved in all the Apollo missions and knew the astronauts personally. The moonquake probe was one of his projects. Once the Apollo missions were over he went to work for Lockheed Space for some 35 years . There is a series to be aired by the BBC before Christmas in which he will play a part. Keep up the good work.
Just heard you on LBC this evening talking about the moon landings. You're everywhere right now. Congrats, it's well deserved. Love the channel
Nice! Was hoping someone would catch that 👍
Congratulations on your award. I was surprised to learn the impact theory was conceived as far back as 1946. I thought it was much more recent. It amazes me how much we knew way back when. Makes me wonder how much more we know now but aren't sharing.
I went to college with Dr. Marc Norman who worked for NASA on moon rocks. We just caught up though the internet after 40 years. I was originally a chemical engineering major but Marc got his PhD in geology. So we have discussed isotopic dating at length the technology we have now is so inspiring. To contemplate that there are people so ignorant that they thing the earth is flat and the moon landings were fake. It is as if we are de-evolving. Neanderthals live among us. I enjoy this channel so much. Thankls
Book or no book, you are inspiring!!!! I show your videos to my 8 year old daughter, you make a wonderful role model. Thank you 🤗🥰🤘
You said so many interesting things, the entire video was awesome.

Congratulations on the award. It's great to watch a channel where the enthusiasm shines through and I get a bit of time learn about the stuff that I stare up at during a clear night, the stuff that ultimately made us.
Dr. Becky, as nice as it is for you to thank us, we also thank YOU, if you were not as good as you are we would not keep coming back for more, your enthusiasm and knowledge is wonderful, so again THANK YOU 😁
Please be the next 'sky at night' presenter.
Dr. Becky, you may be the perfect teacher. Intelligent, enthusiastic, engaging, and beautiful. Your passion for the subjects you discuss shines through every time. If every teacher were like you, the world would be a better place! Keep up the excellent work, and congratulations on your award.
Congrats on your award! Thoroughly deserved. Loved this vid (and all your others).
Hi Dr.Becky
Amazing information shared by you...
You explained in simple way....
I like your videos so much...
Thanks for the video...🙏👍😊
A gold star for excellence! Like Adric!
Wonderful video, lots of great information, lots of brilliant enthusiasm!
Was the moon always tidally locked? If not, when did it sync up?
KUDOS for the Dr Who reference!
Great video, Becky. A field trip, history, current events, an award - good stuff. Thanks much.
Dr. Becky, this was incredibly well done. Your ability to share some
Of the results of the Apollo missions was insightful. I learned so much from this. Thanks.
Just popped in for my regular dose of Dr Becky stuff - not disappointing. Well done and good work. I know you thanked viewers for tuning in, but they wouldn't if the content (and your enthusiasm) didn't make it worthwhile
It's a team effort with our lovely astrophysicist Dr. Becky leading the baand..tried to spell band as she'd say it! Over & over agn l am amazed at how intellectually facile she is and is able to make it so interesting. I felt pulled in slong with my brain being taken over for the duration of the tutorial.
@@herblapp Hats off to the team, and their 'slong'. Does it get more intellectually rigorous than that?
Same nail polish when underwater or when talking about moon missions... consistency!! ;-)
Congratulations for the award!!
It’s my favourite 😂
Apollo 11 landed on my 12th birthday. It's great seeing history in the making
Dr. B, you are a wonderful ambassador for the sciences. Keep doing what you do. ❤️
Imagine the future Moon colonised, commercialised, bult over and an enormous Big Space Mac Mall with a little plaque on the ground saying "This is thought to be the location of the First Human Moon Landing approximately 250-300 years ago. As he took his first step, Caption Buzz Armstone famously said _"I claim this land for the Federation of Google Solar. Long live the Federation!!"_ 😎
It's so important to preserve all this original material and documents, thank God we have the original recordings of the landing... oh wait!! 😱
Caption Buzz Armstone then drove the very first Moon car, a Model A TESLA, the first solar powered car, previously launched to the Moon sitting on top of the Shuttle Rocket!
Upvote for Buzz Armstone.
@blob darkass yes, very rude indeed! But just 50 years later, around 10 - 20% of Americans and 20% of Britons still believe the landings were fake! Add to that a highly controlled digital media, Govts and Corporation with more and more power to control information... just about any history can eventually be invented!! (I wasn't making a serious point originally, but, you know, it's scary what people still believe despite evidence! 😱)
@@JohnDoe-tx8lq That 10-20% of Americans are all Millennial's btw. They can keep believing the landings were faked and I'll keep dismissing them out of hand as always.
"thank God we have the original recordings of the landing... oh wait!!"
Actually, it looks like we *do* have them. Surprised the heck out of me as well.

Ha! I've been to that green sand beach in the Big Island boonies. I stayed in Kona for 6 months. I came for vacation and didn't want to leave :-)
You could do "5 questions we could answer after returning to the Moon" upload. I'm really curious what you'd come up with.
Thanks for the upload,

Your enthusiasm for the subject is fantastic and entertaining. Thanks for the videos Dr. Smethurst.
Thank you for doing what you do.
Keep making videos and I’ll keep watching, liking and sharing.
I always assumed that anything from Mars would be made mainly of chocolate.
It's mostly cinnamon dust. I hear Cinnabon is planning a mission for 2030.
because the chocolate bar is called mars and the chocolate bar is from chocolate therefore everything what is called mars is from chocolate, too but mars is not from chocolate but from dust, rocks etc. so following the path chocolate - mars, mars should be named chocolate and its inhabitants, chocolatians
Can I eat the milky way and still have room for my tea?
Well done (containing yourself) Dr. B. Overall I'm reminded the breadth and depth of space research. It can be overwhelming.
I really enjoy and appreciate your videos. Can't wait to get the book ! Your love of what you do shines through
That was super interesting and informative. I was geeking out with you watching this
I've got one up on Dr. Becky, Dustin, and Brady. I've actually touched (without gloves) a moon rock... along with a couple of hundred thousand other people. Back in 1976, when the Smithsonian's Air and Space museum first opened, (the one on the Mall people now know, there was an earlier one a block away) they had a display just inside the Mall entrance with a small moon rock sample. If I remember correctly, it was about the size and thickness of a US silver dollar (or maybe a quarter) where people lined up and were able to actually touch it. I'm guessing it probably wore away from so many rubs. My father was a photographer for the Smithsonian back then. One of his responsibilities was to shoot photos of the Air and Space museum as it was being built and the displays as they were put in place.
Amazing story!
I was living in D.C. myself at that time. You've brought back some great memories of the new discoveries going on display then. Having had an interest in astronomy and space since the 6th grade, the new Air & Space Museum was easily my favorite building to visit there.
YOU TOUCHED A PIECE OF PETRIFIED WOOD YOU DUMBASS , JUST LIKE THE ONE NASA GAVE THE DUTCH GOVERNMENT AND THEY ANALYZED IT , PROVED TO BE PETRIFIED WOOD . MOONLANDINGS MY ASS !!!!!!!!!!!!!!!
@@levelplanet3841 , chill dude.
I was there (the Mall location) in 2017 and they had a piece of the Chelyabinsk meteor on display on much the same way. It was back off in a wing and not at the main entrance. But was about an inch across and could be touched.
Very cool. Also love the book by Robert Hazen, The Origin and Evolution of Earth.
Your channel is quite lovely.
Read Our mathematical Universe by Max tagmark if u haven't. I think u ll enjoy it.
@@everythingfictional777 read that a couple years ago... Lovely book, yes!
Love your work Dr. Becky. I can never get too much of these types of videos.
Great stories delivered in an entertaining way, well worth the award. Fantastic.
Congratulations on your award. You're really good at explaining complex, science-type stuff to people with less of a background in such things.
No human ever landed on the Moon.
Your video’s have been improving with leaps and bounds. Loved this moon episode
No human ever landed on the Moon.
I love your videos. I watch and listen to a lot of channels and podcasts on astrophysics and astronomy but I CONSISTENTLY get little tidbits of information from your videos that are either interesting and I wonder why they were mentioned before, or completely blow my mind (like how we are in the largest super void we know of, as in that video I was wondering how the night sky might differ for people living in those voids and then BAM... F me... we are those people). Anyway I feel like I hear a lot of the things repeated over and over again (I am looking at you Mr. Tyson) whereas you are constantly teaching me new things. Thanks a lot and keep up the great channel! Also you are adorable and there is nothing not to like about you. :)
Your enthusiasm if so infectious. Wonderful.
Aside from the science content, which I'm sure a lot of us come here for, it's just so inspiring to watch someone do and talk about something they clearly love. Thanks Dr. Becky!
Not only liked your reaction, l second it!!
No human ever landed on the Moon.
loving your knowledge breakdowns and enthusiasm, thank you
Knowledge? No human ever landed on the Moon.
An absolutely joy.
I enjoyed this so much.I'm quite new to your channel and it's class.
Loved this video, Dr Becky. Congratulations on your award: thoroughly deserved.
Congrats on your award Dr Becky, richly deserved. BTW, the views of the Luna eclipse last night were spectacular, kind of symbolic given what happened 50 years ago to the day - cheers.
No human ever landed on the Moon.
You awaken the child like wonder I felt watching Gemini space walks and docking mannuvers as a preschooler. I came into the world the day Vostock one was launched. I saw Apollo eleven lift off to the Moon and return. An Apollo astronaut that had walked on the Moon came to my school and shook my hand. Now I have to deal with an upcoming generation that thinks that the Apollo missions are fake, Earth is flat and yet still believes we are being visited by aliens. My children and grandchildren are dumbfounded by this deliberately ignorant attitude. It is a conscious decision to reject successful human endeavour. Needless to say my family members are aware of the facts. Thanks for the good work you do.
Congratulations on the Award! I was trying to read what it said during the video and was hoping you would tell us what it was for. Well deserved!
I am delighted with all your videos! Please keep making them. I will keep showing them to my students. :)
It's a shame I can only like this once. It's so incredibly interesting Becky, thank you. :D
No human ever landed on the Moon.
Watched this with my two year old tonight. She said, "We go moon?"
for god sake, correct that falsety --NOW, before she is made subject to falshoods for the whole of her life.
for god sake @@MrDaiseymay please don't breed - there is enough stupidity in the world as it is.
That reminds me of one of my dearest memories of my own daughter when she was three, asked me if I could please get the pretty moon from the sky for our Christmas tree.
Yes! And the great thing is - moon AND mars in your and your kids life.
@@MrDaiseymay aww Phil whars wrong can't take the fact that children are learned the truth ? That we've been to the moon.
The "first watch on the moon" commercial that played in the middle of this video for me couldn't be more on point to the content!
Great video and contagious excitement, keep going \o/
Formed in less than a hundred years is much shorter than I was expecting. Amazing
The laser retroreflector shows that cats were in charge of the Moon program.
thats crap---if they were, there would be no disputing it happened
That explains it then
They thought there be mice eating the cheese
@@MrDaiseymay Did I miss your humor, or did you miss mine?
Laser reflector on the moon is hearsay. No evidence of the astroNOTS in the LEM as it apparently landed on the moon. NONE!
Dr Becky , the Moon Rocks are still cool ! I was 8 when they landed , we got our first color T.V that week . The Moon Landing was my Wizard of OZ Moment . I can still Feel the Excitement when I remember from seeing the New Moon rocks Displayed in our Planetarium as a Youngster . Anorthasite From Beneath Adk Mtns on the Moon ? Great Video
Damn sir amazing story
Congratulations! Love your videos. Thank you.
Love you, Dr.Becky!! Thank you for your awesome videos and congratulations on your award!!
I just love your videos. I'm a space nerd myself. I've always been fascinated with Astronomy. Its the physics part that I always can't wrap my head around. The way you explain things makes it less confusing. Thanks Dr Becky!!! Oh and speaking of the Apollo mission. A few years ago I had the awesome opportunity to meet Buzz Aldrin in person!!! I was totally geeking out!! It was amazing to meet with one of my childhood heroes.
Lucky you! 😃
physics is easy if you read or study it from right source . you can find it on youtube too .

Great video!!! We started watching the Tom Hank’s mini series “From the Earth to the Moon” last week. My son who is 8, is running around in a homemade spacesuit. I have been teaching him about the moon landing and what it took to get there. My favorite episode is “Spider and Apollo One. Apollo One was instrumental in my aviation BS accident investigation course. Thank you for being engaging and personable in your videos!!!

9:45 No, no carbon dating... but uranium can be useful.
And if the Moon moving away at present speed has been going on since 4.5 billion years ago then it started out at half of today's distance. Soo, it was probably a bit quicker in the past...
Qi
Incredibly informative, and we'll explained, and so much I didn't know, thanks so much for that 🤗
Well made video, kept me interested all the way to the end!
Damn, Dr. Becky looking good, son...
To understand what happened 50 years ago to end the space program.... watch as I predict there will be decreasing coverage of the 50th anniversaries of Apollo 12, 14, 15, 16 and 17. I would not be surprised if there is next to no coverage of the Apollo 16 anniversary. Apollo 17 may receive some since that was the final moon launch. The decrease in coverage will mirror what happened 50 years ago. Fewer and fewer people cared... and money is not spent on things that people don't care about. This was also coupled with the belief that the money could (and fallaciously believed would) be spent here on Earth to solve other more pressing problems.
That and they obviously didn't land on the moon.
@@nealswanson8684 Of course they didn't. The moon is a relatively tiny sphere a few thousand miles above our flat Earth.
@@laurendoe168 Except that radar, laser, and moon bounce provides incontrovertible proof that it isn't.
I think there's a bit of a false equivalence there. Apollo 11 was a first. Nobody cares about the second - of anything. Human nature.
I doubt there'll be much of anything commemorating Apollo 12. Whatever there is, it'll be almost exclusively limited to NASA and a few other organizations. Might rate a "oh by the way" paragraph in the "this day in history" part of the entertainment section.
@@fromagefrizzbizz9377 Mine was a sarcastic reply to Neal's reply to my original post. Neal apparently is one of those "moon landing hoax" people. I just responded with an equally ridiculous Flat Earth perspective.
Wow..i hv learned so much new from this video!! Thank you for sharing!!
This is on my top lost of all astrophysical bids, thanks and mindblowing!
Hi Dr Becky. How are scientists able to tell that the rock you were holding is actually from Mars??
From its composition.
Because there is a plaque on the bottom with the inscription "Made on Mars" ;-)
Joke aside, it's from the trapped bits of Martian atmosphere in the rock matching measurements done by our landers on Mars.
Carbon dating for moon rocks that are billions of years old? I think you misspoke @9:45. Great video, anyway! I look forward to the next one and grats on the award.
They way you were nerding out about holding a piece of the moon is how I am inside when I remember listening to Armstrong stepping onto the moon in real time. I was a school boy and this was before there was television in every classroom. The principal made an announcement about how quiet we needed to be because of the importance of what was about to happen, then he held a radio up to the intercom microphone and we listened. The principal didn’t need to say anything, the class, the school, and the street outside went quiet, and everyone listened to it happening live. It was a magical moment that anyone who heard it will never forget.
If you are ever in Sydney, Becky, you must go to the Powerhouse Museum. They have a piece of moon rock with a photo of the astronaut picking it up at the edge of a crater. But you might not guess where it and the photo is located. It is directly under the throat of a Saturn 5 engine. It is the only one outside of the US. Australia was given some very special treasures by NASA because of the Australian role in the moon landing. That footage of Armstrong coming down the ladder was relayed to the rest of the world from the big radio telescope dishes in Australia at Honeysuckle Creek, and the 64 meter dish at Parkes. Even today, the only radio dish in the NASA network sensitive enough to receive transmissions from the Voyager space craft are the same dishes that pulled in the signals from Apollo 11.
BTW, a movie was made about the drama surrounding the telescope receiving the lunar landing is an excellent Sam Neill movie called “The Dish”. It is a drama/comedy that exaggerates the country yokels side of things (the big Dish at Parkes is extremely rural) but balances that with the drama of the moment. I get tears whenever they show the huge gears of the telescope moving. The big drama was the weather ultimately. They operated the telescope beyond design limitations in gale force winds to get that signal from the moon. Highly recommend that movie. One of the rare times science and a telescope is the subject of a movie. en.wikipedia.org/wiki/The_Dish
Dr. Becky, your "crescent moon" necklace looks more like an "annular solar eclipse" necklace since spherical bodies (particularly airless ones like the Moon) never exhibit a crescent spanning significantly more than 180 degrees (although admittedly in this epoch our Sun, visually from Earth, is never that much larger than the Moon). Love your podcast and the award was well deserved.
3:30 Answers in Genesis ... wtf ?
What a strange origin for an accurate scientific image.
@@Morbacounet My brief scan of their web site seems to indicate that they have a somewhat schizophrenic view of science/religion. For example: They don't seem to have a problem with observational science, gravity and so on (eg that diagram), yet at the same time dismiss its (largely proven) consequences for the age of the earth et. al.
Everything goes well until the word "evolution" comes up, and then they lose their collective minds.
This is the sort of logical self-contradiction you can only hide by shovelling on mountains of religious bafflegab and the usual "muh buk sez so, so it must bee".
@@fromagefrizzbizz9377 You know what they do... They pull verses from the Bible and see how much they can bend the interpretation to match current scientific knowledge just so they can say "SEE? the Bible knew it all along and science only now has caught up!". And regarding scientific knowledge that directly contradicts the Bible and cannot be interpreted away, they will just say "well obviously science is wrong on this one, but it will eventually figure it out".
Probably just a google image result for the proper tidal forces she wanted, and pulled it from the originating site; which happened to be answers in genesis; she might be naive of the rest of the stuff they have.
Since the earth is floating through space, isn't every rock technically a space rock?
In space no one can hear you rock. \m/
We and earth are in the atmosphere so not in space, cos if we were all our blood would literally be boiling
@@dominicbriggs1182 Yes, but where is the system that includes us, the Earth and the Earth's atmosphere located?
Thank you for sharing as usual, and congratulations on the award!
Excellent, Professor. Always wonderful to watch your presentations
9:45 Please don't give the young-earth folks ammunition with a clip of an astrophysicist telling everyone we can "carbon date" 4-billion-year-old rocks, and igneous ones at that!
Also, the oxygen (16, 17, 18) isotopes measured are stable not radiogenic. There are no radioactive isotopes of oxygen with half-lives longer than a few minutes.
@Carlos Saraiva To be fair, she just used oxygen isotope ratios as a composition comparison with Earth rocks. But, as Jason pointed out, her explanation of using oxygen isotope decay was incorrect. So both points were wrong in their own ways.
wow... this is pretty disturbing to me that she doesn't understand the difference between radioactive isotopes and stable isotopes. This, in combination with her having used an illustration from Answers in Genesis in this presentation makes me very suspicious about her underlying ideology.
just so you're aware, Creationism routinely impugns the legitimacy of radiometric age dating. I don't know if dr. Becky's answers are "honest" mistakes or not.
just so you know, at the time I was working on my PhD in geology at Penn State, there was a Creationist "mole" who was awarded a PhD in geology while keeping his Creationist beliefs completely secret. he went on to work at The Institute for Creation Research, where to the best of my knowledge he still works today. Thus, as amazing as it may seem, this _can_ be accomplished through clever manipulation of terminology and language.
There's a bigger problem with the rocks, particularly the rocks in the Apollo photos. They all have solid evidence of being subject to WEATHER.

1. How can an object land on a soft dusty surface yet make no mark?
2. How can an object become buried in dust yet remain free of dust?
3. How can an object have it's corners worn away?
This of course is only possible on earth.
@@MendTheWorld I'll cut her some slack. This topic is a bit outside her primary studies and it's easy to make a minor technical mistake when you're trying to assemble this type of content for general consumption. She frequently subtitles corrections over mistakes.
Hollywood... Area 51 is a perfect place to record the man's journey to the moon!!??
Congrats on the award. Thanks for sharing knowledge with us.
Couldn't think of anyone better for that award! Congratulations!
9:45 carbon dating?
oops! someone heard it before me. You often hear people say carbon dating when they mean radiometric dating.
nice
Why would you use a *wrong* diagram from Answers in Genesis?
Perhaps because Genesis isn't the correct diagram.
CorwynGC - yeah, the tidal bulges need to be on the earth-moon center line. And, “pro tip”: there are no answered in Genesis :-)
@@-johnny-deep- Nope. The tidal bulges lead the Moon. The Earth rotates faster than the Moon's orbit revolves. That's how the Moon gets pulled along and gradually bleeds off Earth's rotational momentum.

And the earth orbits the earth/moon barycenter. Which causes the opposite high tide.
@@Markle2k - Hmm. Thanks for the correction. I guess I never really did understand tides. I'll have to read up on it again. So then what's wrong with the diagram? Wrong side of the moon facing the earth? Earth doesn't rotate about a line through south africa? The earth / moon size difference is shown to correct scale, though obviously their distance isn't.
The moon moving away is consistent with things like the continents africa and south america slowly moving apart. So cool when peope bring pieces together little by little like that.
Leave aside scientific content of this video I'm absolutely blown away by Dr Becky enthusiasm which is nothing but infectious. She is living proof that you can be scientist and be not boring in the same time. World of science desperately need people like Dr Becky.
Ps. Number of subscribers still rocketing ;-)
Just a "heads up" Dr. Becky - that graphic you put up for the tides & tidal forces between Earth and the Moon is used by Answers in Genesis to make the case that the Earth CANNOT be as old as "evolutionists" (whatever the Hell they are supposed to be) say it is because the rate of recession of the Moon away from the Earth would have caused us to lose it by now.
Not really a pool of ideology that a legitimate scientist such as yourself would want to be associated with (jus' sayin').
Please don't say "carbon dating" when referring to 4-billion year old rocks.
@Carlos Saraiva Those carbons never dated. Just fucked once.
I completely love how much you LOVE your job!
That was a good video, so much new knowledge for me. I remember my father waking me to watch the landing.
I love your videos and your work but please don't use images from answers in genesis, that image is not even correct!
I was kinda disappointed to see an image from AiG too, surely there had to be another source. Especially since they try to use the Moon's recession to prove the Universe can't be millions of years old.
Ha, ha! Using a graphic from Answers in Genesis for an actual science video. Good joke!
All I could think of was "Ham and eggs" from Paulogia. Lol
I was just gonna post about this. I'm wondering (hoping!) that it was a joke, and that our Dr. Becky has not fallen sway to the Answers in Genesis crowd.
I noticed it as well... I was a bit startled by it.
Thank you for making great videos!!! love your content 👍👍😁
You should soon have a silver YT button! Well deserved too. Thanks for your content.
