Where did the Moon come from? A new theory | Sarah T. Stewart


Nobody likes to make a mistake. And I made a whopping one. And figuring out what I did wrong
led to a discovery that completely changes the way
we think about the Earth and Moon. I’m a planetary scientist, and my favorite thing to do
is smash planets together. (Laughter) In my lab, I can shoot at rocks
using cannons like this one. (Cannon shot) (Laughter) In my experiments, I can generate
the extreme conditions during planet formation. And with computer models,
I can collide whole planets together to make them grow, or I can destroy them. (Laughter) I want to understand
how to make the Earth and the Moon and why the Earth is so different
from other planets. The leading idea for the origin
of the Earth and Moon is called the “giant impact theory.” The theory states that a Mars-sized body
struck the young Earth, and the Moon formed from
the debris disk around the planet. The theory can explain
so many things about the Moon, but it has a huge flaw: it predicts that the Moon is mostly made
from the Mars-sized planet, that the Earth and the Moon
are made from different materials. But that’s not what we see. The Earth and the Moon
are actually like identical twins. The genetic code of planets is written
in the isotopes of the elements. The Earth and Moon
have identical isotopes. That means that the Earth and Moon
are made from the same materials. It’s really strange that the Earth
and the Moon are twins. All of the planets are made
from different materials, so they all have different isotopes, they all have their own genetic code. No other planetary bodies
have the same genetic relationship. Only the Earth and Moon are twins. When I started working
on the origin of the Moon, there were scientists that wanted to
reject the whole idea of the giant impact. They didn’t see any way for this theory
to explain the special relationship between the Earth and the Moon. We were all trying to think of new ideas. The problem was,
there weren’t any better ideas. All of the other ideas
had even bigger flaws. So we were trying to rescue
the giant impact theory. A young scientist in my group suggested
that we try changing the spin of the giant impact. Maybe making the Earth spin faster
could mix more material and explain the Moon. The Mars-sized impactor had been chosen because it could make the Moon and make the length of Earth’s day. People really liked
that part of the model. But what if something else determined
the length of Earth’s day? Then there would be many more possible
giant impacts that could make the Moon. I was curious about what could happen, so I tried simulating
faster-spinning giant impacts, and I found that it is possible to make a disk out of the same
mixture of materials as the planet. We were pretty excited. Maybe this was the way
to explain the Moon. The problem is, we also found
that that’s just not very likely. Most of the time, the disk
is different from the planet, and it looked like
making our Moon this way would be an astronomical coincidence, and it was just hard
for everyone to accept the idea that the Moon’s special connection
to Earth was an accident. The giant impact theory
was still in trouble, and we were still trying to figure out
how to make the Moon. Then came the day
when I realized my mistake. My student and I were looking at the data
from these fast-spinning giant impacts. On that day, we weren’t actually
thinking about the Moon, we were looking at the planet. The planet gets super-hot
and partially vaporized from the energy of the impact. But the data didn’t look like a planet. It looked really strange. The planet was weirdly
connected to the disk. I got that super-excited feeling when something really wrong
might be something really interesting. In all of my calculations, I had assumed there was a planet
with a separate disk around it. Calculating what was in the disk
as how we tested whether an impact could make the Moon. But it didn’t look that simple anymore. We were making the mistake of thinking that a planet was always
going to look like a planet. On that day, I knew that a giant impact
was making something completely new. I’ve had eureka moments. This was not one of them. (Laughter) I really didn’t know what was going on. I had this strange, new object
in front of me and the challenge
to try and figure it out. What do you do when faced
with the unknown? How do you even start? We questioned everything: What is a planet? When is a planet no longer
a planet anymore? We played with new ideas. We had to get rid
of our old way of thinking, and by playing, I could
throw away all of the data, all of the rules of the real world, and free my mind to explore. And by making a mental space where I could try out outrageous ideas and then bring them back
into the real world to test them, I could learn. And by playing, we learned so much. I combined my lab experiments
with computer models and discovered that
after most giant impacts, the Earth is so hot, there’s no surface. There’s just a deep layer of gas
that gets denser and denser with depth. The Earth would have been like Jupiter. There’s nothing to stand on. And that was just part of the problem. I wanted to understand the whole problem. I couldn’t let go of the challenge
to figure out what was really going on in giant impacts. It took almost two years of throwing away old ideas and building new ones that we understood the data and knew what it meant for the Moon. I discovered a new type
of astronomical object. It’s not a planet. It’s made from planets. A planet is a body whose self-gravity is strong enough to give it
its rounded shape. It spins around all together. Make it hotter and spin it faster, the equator gets bigger and bigger
until it reaches a tipping point. Push past the tipping point, and the material at the equator
spreads into a disk. It’s now broken all the rules
of being a planet. It can’t spin around together anymore, its shape keeps changing
as it gets bigger and bigger; the planet has become something new. We gave our discovery its name: synestia. We named it after the goddess Hestia, the Greek goddess of the hearth and home, because we think the Earth became one. The prefix means “all together,” to emphasize the connection
between all of the material. A synestia is what a planet becomes when heat and spin push it over the limit
of a spheroidal shape. Would you like to see a synestia? (Cheers) In this visualization
of one of my simulations, the young Earth is already spinning
quickly from a previous giant impact. Its shape is deformed, but our planet
would be recognizable by the water on its surface. The energy from the impact
vaporizes the surface, the water, the atmosphere, and mixes all of the gases together
in just a few hours. We discovered that many
giant impacts make synestias, but these burning, bright objects
don’t live very long. They cool down, shrink
and turn back into planets. While rocky planets
like Earth were growing, they probably turned into synestias
one or more times. A synestia gives us a new way to solve
the problem of the origin of the Moon. We propose that the Moon formed
inside a huge, vaporous synestia. The Moon grew from magma rain that condensed out of the rock vapor. The Moon’s special connection to Earth is because the Moon formed
inside the Earth when Earth was a synestia. The Moon could have orbited
inside the synestia for years, hidden from view. The Moon is revealed by the synestia
cooling and shrinking inside of its orbit. The synestia turns into planet Earth only after cooling
for hundreds of years longer. In our new theory, the giant impact makes a synestia, and the synestia divides
into two new bodies, creating our isotopically
identical Earth and Moon. Synestias have been created
throughout the universe. And we only just realized that
by finding them in our imagination: What else am I missing
in the world around me? What is hidden from my view
by my own assumptions? The next time you look at the Moon, remember: the things you think you know may be the opportunity to discover
something truly amazing. (Applause)

  1. Makes no sense giving the fact that theres processed Metals Like Brass and mica. Even the fact that theres radioactive waste that Only comes from burnt out nuclear power

  2. How many times do you have to toss a dime into the air and let it fall freely to the table before it lands on its edge and remains there on its edge?
    .
    Earth’s moon rotates on its axis at the exact speed to ensure that the same surface is always towards the earth. We never observed the far side of the moon until we orbited it with unmanned or manned space craft.
    .
    I’m not a mathematician, but I expect you could get that dime to land on its edge multiple times in a row sooner than random chance would account for the moons rotational speed.
    .
    Then there’s the effect of the moons gravity on the oceans tides and how indispensable that is to the earths ecosystems and our very survival.
    .
    How many rolls of the evolutionary dice would be necessary before random chance produced the right combination of pre-existent material required to produce a hummingbird, and not just one hummingbird, but two: a male and a female?
    .
    This lady is abandoning science for mythology. She is a scientist devolving into a priestess.

  3. Sssssorry but that lady/hobbit was disssstracting with her lisssssp and hunchback.

  4. love the courage for a very original and novel thought.

    the model seems strong by logic however since there is no detailed description of the underlying processes ( what if there is new physics we still have to learn and what if the computer model doesn't know all the variables it needs to compute on just yet)- we can take this idea as another proof for how much more we still have to learn.

  5. Meh. Maybe. But then again, Nick Pope and those two Russian scientists say it was Manufactured. 😜

  6. 2:00 The earth and Moon have SIMILAR isotopes. This does not bode well for the next few minutes.

  7. == The earth is spinning with 30 kilometers per second on the equator. Right? Why the a flight from Los Angeles to Tokyo take the same time as the flight from Tokyo to Los Angeles. Why the clouds are moving in different directions ?

  8. Do not the Unbelievers see that the heavens and the earth were joined together (as one unit of creation), before we clove them asunder? We made from water every living thing. Will they not then believe?

  9. The moons compesition is very different from that of earth and is much older than the earth by over a billion years and is believed to be almost as old as the universe itself, there are ancient cultures who have distant memories of a time before the moon. Sorry but your simulation software has a bug or bad information entered as the theory your telling us is fact is impossible given the vast age difference between the two bodies, your theory is equivalent to saying a the following… "earlier today a 20 year old english woman gave birth to a 35 year old african man who lives nextdoor to her"

  10. The leading idea for the earth and moon is found in the book of Genesis.

  11. Is this about the moon being made or a disc in earth or just planets forming I can't tell

  12. The Moon came from Irsa Minor about 26,000 years ago. Idk who brought it, probably the Orion Group. . . .

  13. The moon was a large asteroid that impacted earth in the pacific. The explosions allowed earth dust and rocks to cover the moon with the same isotopes. Ganymede which is structurally similar to the earth probably broke off and was captured by Jupiter. The Mariana trench is crescent shaped and fits the dark side of Ganymeade like a jig saw puzzle 😇

  14. This is all hypothetical nonsense! We all know that moon is a giant cheese ball that's been genetically modified to glow in the dark duh! 😏

  15. The Moon is the condition described by the third day in Genesis; only on the forth day was the Earth and Moon separated

  16. What if we hadn't gone lunar and had to fake it with earth (rock)isotopes. Its got to be manufactured by ancient dwellers. Brilliantly portraid

  17. You're an idiot woman, you need to study moon deep inside before you talk not just the dust and rocks on surface

  18. This is hogwash. In just the first few minutes everything she says about the Moon is wrong based on what I've learned in 40 years as an astronomer. My question is who put her up to this and why.

  19. The earth is a planet is the biggest lie ever told, in the history of humanity. The world is waking up knowing the earth is a centre of universe. Is the greatest consciousness shift in the history of humanity. The moon is a luminary in your local sky, and not physical ball in the "vacuum of deep and infinite space"
    A scientist named prof.R.Foster told that the moon is a plasma, not rock, and that landing on it would not be possible. The moon is a plasma then all gravitational theories are out and a new concept of the cosmos and of its lows has to be evolved.
    NASA they are liars they faked the moon landing and are lying to us each and every step.
    So trust your eyes and trust your experience. Trust your feelings and trust your intuition.
    Search for the truth.

  20. I’ve had several eureka moments in my life clicking on this time theft device wasn’t one of them. Smh..

  21. Both China & India have written history going back thousands of years, long ago a second moon came & parked in orbit & it was as big as our Moon, then a smaller Moon showed up & parked in orbit. All 3 Moons were Hollow & have their own means of traveling.

  22. Oh! for crying out-loud….Why?
    are people so stupid? We all ''really'' know that it is impossible to have Planet Earth & The Moon….in such perfect alignment unless it was created. Maths has proven that.

  23. If thats true then why do ancient people say one day it was there.. So that would mean they lived here on earth with no moon…

  24. Please explain how this is science!?!? It's not!!! This is anti science! Science is studying something without a preconceived conclusion and analyzing the actual factual data to reach the real conclusion. These people started with an answer and work backwards trying to make that answer work. The exact opposite of what science is supposed to be.

  25. Just reading the comments because I know watching the video will be a waste of time

  26. The better question is WHO FREAKING CARES WHERE IT CAME FROM! If a DVD fell from the sky showing you exactly how it happened how would it benefit you ? How would it enrich your life?

    What good would it do? Your just pissing you life away wondering about something that you will NEVER know, so stop thinking about it.

  27. Everybody that has watched the disclosure movies Star Wars knows that the moon is really a Death Star in camouflage. Even children know what a Death Star is.

  28. But the moon does not rotate on its own axis. We always see the same side of the moon. It is not spinning. The Earth spins or wobbles on its axis.

  29. Maybe this ? possibly that ? we don't know the truths and we are lied to constantly and we haven't been back to the Moon with a manned ship since 72. Thinking about it no manned moon landing in 50 years. It sounds like somebody's lying either we never been there before or we can't do it again with all the technology we have today !!! I call BS.
    Use your lab to explain 3 buildings falling on 911 and the single hole in the Pentagon and I will gibe some respect to the info if you spent the time to show how. 911 was a LIE on the tv PROGRAMMING SYSTEM.

  30. Why enter a field where none of your theories can be proven? Her impact theory is basically no more valid than if she said the moon was put there by a giant sphagetti monster. There’s no definitive proof for either claim. I think she just likes smashing rocks together in her lab.

  31. The moon is not that old it was placed there as a base which blocks the sun creating night and day also the tides in our oceans were created by the pull of the non spinning object in our sky. Chuckle because of the contrast to the explanation that is given to its existence today. Soon

  32. Damn I guess these mere humans think they're smarter than God now… God said he made the moon and put it in the sky. That's good enough for me and makes waaaay more sense than anything I've heard from any of these theoretical dunces.

  33. This has got to be one of the if not the, most insanely rediculous theories that i have ever heard of. i mean seriously, please tell me that not even one person thinks that this is anything other than another luciferian attempt at trying to deceive the masses of sheeple. To those who actually put any stock in this babbling idiot, i will pray for your souls.

  34. Instead of a solid object being to subjected to a giant impact, it was a synestia which was subjected to a giant impact. The two objects then became thoroughly mixed together, and then we still seem to need to explain how they separated to become twins.

  35. For anyone who believes in aliens.
    Maybe the moon was created by aliens millions of years ago as an observation earth post? Lol just a fun theory.

  36. Another theory of no interest since we can never prove that it is the reality

  37. The mistake you made is Trying to convince us that the moon is a Natural Satellite. The Moon was placed in its position long ago, and is the only tidal lock relationship of Planet to Moon in our galaxy.#Research

  38. What is your opinion about this video , please investigate
    1965 scientist claims the moon is plasma, landing on it won’t be possible
    https://www.youtube.com/watch?v=1oCNGcbwxWg

  39. Yeah, sounds about right 🤔 possibly

    I would've liked it if she explained more about "isotopic twins" though. 😏

  40. Poor people. You don't believe in logical Flat Earth model but believe in this nonsence.

  41. God made it to light the night for us. It’s cratered because the fountains of the deep were opened up during the great flood and it blew chunks of Pangea into the sky and space. That’s what the craters are from on earth and the moon. Also, explains why comets are made of earthly materials. It’s simple really.

    But! If you want to be scratching your head, watch this video! 😂

  42. And didn't the crowd just Love Her!? A new heroine of Science?, well for a day or so! Go U little Beauty!

  43. She reminds me of the ET dubbed "Mona Lisa" that was allegedly discovered by secret apollo 20 mission in a massive craft that crashed on the moon hundreds of thousands of years ago……..funny she's offering a new theory about the moon.
    https://youtu.be/4GBj6mqqaok
    skip to 10:11 for a shot of the humanoid.

  44. The Sumerians cuneiform tablets recorded the the Earth n the Moon coming into being after the collision of two planets…lolz..Tiamat colliding with Nibiru….

  45. I just came up with another theory. The diamagnetic elements present in our primordial planet that lacked a magnetic field were ejected once a magnetic field was established. This mass that was attracted by gravity but repulsed by magnetic forces had it's own gravity and it swept up it own dust. This mass of diamagnetic elements is asymmetricaly distributed in lunar mass causing its locked orbit.. these would be handy elements

  46. Why dont they say to just read the book of Enoch. Its explains everything thing in that very old scriptures.

  47. Lol there’s a new theory for everything when it comes to mans word because mans word isn’t as powerful and true as Gods. Read the bible, it’s not fairytale everything about everything is in there before man discovered it.

  48. Sarah, you got a reason for moon's large size, but no reason for that size to perfectly block the sun during an eclipse. The odds of that happening are astronomical (pun intended). Try using your experimental canons to create a specifically-sized moon. Astronauts had trouble drilling into the moon, because they kept running into processed metals like Titanium.

  49. That's because it was a fragment just like the Earth from Tiamat which the rest of Tiamat is the kuiper belt

  50. Or the isotopes are the same cause the dirt and rocks brought back by the Apollo missions were actually FROM EARTH Lol

  51. She is BS, the moon is made of titanium, one can only dig a little which is dust then hit titanium. That is why no plant life, one can't grow anything from dust and titanium.

  52. Since she has her sighting lost and not focused at the viewers, seems to be blind… or maybe observe her dear Moon, traspassing the top of the room.

  53. Apollo didn't bring moon samples to Earth. The samples tested are from Earth so they of course they're the same. The moon may have been brought here by aliens. Time will tell.

  54. dosent the laws say eqeal and posetive reasction so if a plantary boddy hits earth close to the sise of the moon that amount of matreal would have rised in to the atmospher around the planet as well as a grate deal of steam and other gasses and the planet would spine faster then its speed befor and the steam and vaperized rock would come together and become like a cloude of concreate that would harden from the suns radeation on one side and be vary cold on the other gasses would get traped and the center be holo form thowes gases intel thay are expeled from heat now the moon had to come from the earth as it is gravationly lock to the planet meaning that the hevest side was crated in are gravaty if it in it size was created out side earth ordet its offset waght and size would never had been abel to lock in to the obit the acutal inmpack zone can still be seen it is the crest of chine napa and the relese direction would create the indffrent orbet the moon has if its impact was when the earth was on its origel axse not the curent 30 some digress

  55. This theory is the best I’ve heard. Planetary bodies have gone through many changes in the billions of years since their formations. Apart from all the conspiracy theories this seems like a possible scenario. Remember the moon has and still is today been instrumental in influencing tides and animal behavior on our planet.

  56. as far as I know – there's a giant impact theory about almost every single body in our solar system… ;-P

  57. The Moon was purpose built at a specific size in a specific orbit by an ancient advanced civilisation . The materials quarried from mother Earth. Evidence of huge Quarry's and ancient machining all around the globe . Also evidence that it is hollow ,impacts cause it to ring like a bell .

  58. lot of shade being thrown in the comments, but I commend her for at least producing an original thought and publishing work on the matter that can be reviewed by both her peers and the public. Science!

  59. No its not. Earth is a closed system, we never went to the moon. Fake moon rocks donated by NASA turned out to be putrefied wood in the Netherlands.

  60. So what are all the moons around other planets made from why is this such a conspiracy and shenanigans I keep hearing on this it's Hollow it's fake it's brought there by aliens I think you people are all f**** crazy the more I see stuff like this the more I feel closer to God and our lord Jesus everything is so mythical just like how powerful water is and how much of it we are made of should almost tell you this is a miracle and it didn't just happen it had to have been created it's too well put together there's too many questions put all you people in one room about a topic of the Moon and not one of you will agree it's shenanigans close your eyes and pray to the Lord

  61. No, the origin of the Moon is that it originated from the planet Jupiter outside the orbit of Callisto and was moved here about 15,000 years ago. Yes indeed, there was a period when the Earth did not have a Moon. We are all under the scrutiny and beady eyes of a far higher intelligence. 👽 And they are just some of the weird species.

  62. so why don't we see any young planets with equators at the tipping point anywhere in our galaxy?
