- Move over Pluto - Is there a 9th planet in our Solar System? Dr. Malhotra and other planetary scientists have discovered the theory of Planet 9 after noticing that something was exerting a gravitational force on objects in the Kuiper Belt - an area of comets, the dwarf planet Pluto and huge icy objects beyond Neptune that encircles the whole solar system.

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
An esteemed professor of physics, member of the National Academy of Sciences and of the American Academy of Arts and Sciences, Dr. Malhotra is an esteemed astrophysicist. She has examined a wide variety of topics, spanning from extrasolar planets to the meteoric bombardment history of the planets. She has revolutionized our understanding of the formation of “Plutinos” and other small planets, as well as the orbital migration of giant planets. She cannot help us understand why man-buns are in style.

The humour of "It will make horoscopes more accurate" that line alone made this talk worth watching :)
what do you honestly know about astrology ... nothing.
I didnt get that joke
Will it help if i google horoscopes?
@@omarthedeadaziz6756 Horoscopes are essentially a reading of the position of the planets and stars in order to predict the future. They're like crystal balls or tea leaves. Not a real thing, but the last time I received a print newspaper (middle 2000's) they were still printed in the entertainment section near the back.
delveling why? Tauris is the only sign missing its planet.
Strykenine thats not astrology you’re reffering to.
I love the science of planets and cosmos. Beautiful presentation.
My imagination runs wild with a theory like this. I also loved the way she described how the discovery or rediscovery of Neptune changed the way people relate to the cosmos. I believe a discovery of this magnitude would push humans to a type one civilization.
No One ever mentions the Sumerians had a heliocentric solar system modeled with all the known planets. 6K years ago
But did the Sumerians gave any clue to where the 9th planet is?
@@freenational perhaps they did, but if they did, how did they know ? 🤔
@@GrimJerr , to the best of my understanding, it was the Gods that told them that.
@@freenational You Mean Aliens right, there are no Gods
@@GrimJerr , that depends on what your definition of Gods is. If those beings have power over human fortunes, you would consider them as Gods whether they come from an alien world or not. However, to make sense of that, you need a scientific approach. I think Lloyd Pye gives the most cohesive argument on the subject.
If there is truly a planet 9 out there somewhere I hope I live long enough to witness its discovery... I am going to have so many questions for our creator when my time comes :)
This was an amazing talk, she was hilarious!
Thank you, Dr. Malhotra for this talk! It will give me more to think about when I stargaze, finding Jupiter, its moons, Mars, Venus, Saturn. But THIS. . . . . .
I love her planetary dynamicism as it's was so good just so good nobody does it better.
It blows my mind that there may be another planet out there. We've been finding planets in distant star systems for decades, but there might be more planets within our own that our current technology and mathematics haven't been able to find is just fascinating.
Keep up the good work!
Planet NINE wow that was amazing that I share thank you very much for your content with TED
I found it exciting to see the transitions of several planetary bodies look like sound waves. Wow that is a conformation.
I love the science and the sleuthing of it all!
I love the geometry!!! 😊
*They want to call it "planet 9" but many people have been expecting to find Planet X/Nibiru a lot longer than these johnny-come-latelies.*
Or what about the CMEs at night? ISWA Magnetosphere goes 13 and 14
Haven't even finished half the video and I am deeply satisfied with this. Definitely leaving a like
Wow, I'm early for a great TEDx Talk! At least comment section wise. lol
Newton and Kepler saw clockwork in what they knew on the scale of human history. 400+ years later, IMO they're still great for the changes they brought about we couldn't be where we are without.
This reminds me about a 1950s movie when worlds collide. How a rogue planet may be captured by our solar system and cause chaos.
translating from english to english ...awesome ^^
Fascinating! Love this!
5:00 she gets to talking about planet nine.
Thanks!
Yes thank you. Ted talks are usually pretty lame, but I am interested in the subject.
As I was listening to this talk, I kept imagining Einstein's model of gravity as a sheet suspended with the Sun at the center and the planets circling the dimpled sheet only to be ultimately drawn to the center. Then I though of all the planets with their own gravitation "sheets." If the Sun and all the planets are not on a linear sheet then there are sheets bunched up all over the place until it is a big ball of infinite sheets...then I remembered the drier needed to be checked.
🤣🤣🤣
What a brilliant speaker
It's fascinating!
Can't wait for the accurate horoscopes! :D
BaldingClamydia not really, the outer planets are slow moving, affect generational trends.
The Summerians who lived about 6000-8000 years ago already knew about this.
Her calculations predict an orbital period of 17,000 years. How does that tie in with 1 sar?
Blinded me with science...clap clap clap
Tres bien expliqué, merci
We demand to have Pluto back.
Who was elected by an international democratic vote to demote Pluto? Nobody - no single person or group - can demote what wasn't theirs to start with.
When you end the CZcams Conspiracy theory spree at 4am, and it was Nibiru the whole time.... :P
Presented in a very lucid, no non sense manner. Can have huge impact on understanding of our solar system if Planet 9 is found.
Thank you Dr. M
It seems to me that the more recently talked about "Planet 10" would be more of the sheperder of most classical KBOS; it's estimated to be located between 45-60 AU, and currently in the Plane of the Milky Way, where we can't easily see it. Sedna and other Sednoids are NOT Kuiper Belt objects, they're more "scattered", with the most distant objects like Sedna probably being influenced more from a body other than Planet 10.
Also, the most direct evidence of a roughly Mars sized object at the edge of the Kuiper Belt is the Kuiper Ciff; an area where few bodies are known.
It would also be a triumph for the Sumerians, the Annunake and us.
Now this was facsinating talk!
Excellent talk.
Ancient civilizations kad more knowledge then we are willing or able of accepting ...
That shout-out to Pluto was beautiful, she didn't have to do that
amazing..........pluto and neptune resonance orbit
amazing how we are narrowing in on finding it slowly but relentlessly. if its at the odd off kilter orbit. so distant and so dark it seems its no wonder we cannot yet locate it.
Great lecture!!!... now back to cat vs balloon videos...
Ah, the essence of the internet xD
😂😂😂
lmao
Send me the link send me the link !
And that is how a scientist handles the "are there other planets in the solar system" question.
And don't you dare start calling one of these objects Nibiru, you'll only forget which one it is and then there will be several Nibirus and that's just unscientific.
One of the more intelligent discussion on the planet~9 @ Nibiru @ Woodworm ... Thank You So Much for letting us know that >>> There is Something really Out there & We were not being Superstitious! 🕯

I am fascinated by the pricision of her deductive research. Yet, I have to say my own planet already completely occupies me and I don't really care how many more planets there are. I hope they give Planet 9 a memeworthy name though, like Planet Xenu.
"Ancient civilizations had a very simple concept of the universe"???
Sumerians made detail descriptions of the planets, they knew about a large extra planet and made equations that are thought to be planetary distance calculations. Egyptian, Hindu, and Mayan civilizations, among others, aligned buildings to the Pleiades.
Is that "simple" to you?
yes also they knew it comes to closer to earth in every 5000 year. (as our scientists suggest the path of planet 9)
yes also they knew it comes to closer to earth in every 5000 year. (as our scientists suggest the path of planet 9)
It's a bit sad that she doesn't know better, but this just shows how this narrative of ancient civilizations being primitive is something that is so deeply engraved in our overall knowledge of the past. But with the new discoveries regarding the Younger Dryas, much older megalithic sites, soon enough we will have more and more evidence of some ancient civilizations being far more advanced than we have been giving them credit for.
@@theSUBVERSIVE Amen! I suspect the largest ancient civilizations to be upwards of 30,000 years old.
@@theSUBVERSIVE
I just finished Graham Hancock's Magician of the Gods and would have to agree that scientists have a very orthodox position in regards to the low and unsophisticated technological development of the ancients. His theory about a subset of them having a sophisticated understanding of the our solar system and physics seems to explain much. The Younger Dryas Boundary problem is very exciting.
I don't know about west but I bet ancient Indian Civilization knew far more about Planets , Sun , Moon and Stars. They studied Astronomy and used Geometry Maths to Calculate various distances and constellations and also studied the effect of planetary motions , stars and moons on earth and on humans . It is far complex and in-depth subject to be explained in a comment section. Lastly there are many temples of Navagraha ( Nine Planets ) in india
Awesome lecture
Beautiful
I love her sense of humour xD
Chow Tom funnier than Jay Leno!!!
yes nigel
She is quite witty with her humour
And now with our most sophisticated spy-1 radar, we can constantly track these vehicles, performing 27000 miles per hour speeds, changing direction on a dime, coming from space to 80,000 ft then dropping at 27000 miles an hour to 50 feet above the water, able to maintain, I'm surprised the Navy told us and then showed us the footage, we have extraterrestrial visitors hello
I think she had Artie Lange punch them up for her.
The oldest language most likely the first account of the older oral tradition mentions 9 planets and their epic tales of the travel of Marduk with 4 winds, like 4 satellites. How could they see 9 planets without having invented the lens? Suggesting a twin star system lighting up the sky, one of the inner planets was later revealed to be currently moved to the outer system. The way early humans saw the heavens passed down in oral tradition then recorded on clay tablets we found in large numbers
1. They DID have telescopic lenses, but none have survived, or been found. (Glass may be WAY older than we think.)
- or -
2. The sky THEY saw was WAY different than the sky we see now. Publicly, we still teach the universe as a "clockwork" but, increasingly, evidence points to long periods of stability, interrupted by periods of chaos. Mount St. Helens (Washington State, USA) was quiet for more than 100 years before the 1980 eruption. Fortunately, the direction of the blast was away from larger population centers. If "unexpected" things can happen here, they can happen "there" (in the larger cosmos), too. "As above, so below" works both ways, I believe.
Just because we think we "know" something, doesn't mean we understand it fully. 🖖
Great job what a lovely lady !
I have a small problem with the suggestion of those orbital resonances... they don't divide into each other very well. The divisors aren't properly in agreement. However with a slight twiddle it might work that they could all sort-of divide into 6, which may be enough, though that may still suggest that the shepherd planet is orbiting relatively close-in vs the outermost ones pointing towards its existence?
Sumerians knew about the 9th planet, ✌🏻
Thank you for clearing this up. The intro about the ancient way of thinking about our solar system was off and condescending.

It’s really strange you can type and yet have a single digit IQ...
@Macio Luko What was pathetic was how those Portlanders instantly laughed at the mere mention of our ancestors limited knowledge.
Somehow it didn't surprise me, seeing how petulant people in that city have been acting...
I know, Carl Sagan suggested that some tourist visited the Dogon and told them about Sirius B .... sure, must have been an astronomer with the latest findings and the Dogan developed rapidly their whole culture within a few years.
I really hope Planet Nine and Planet X are found in my lifetime.
_ Spedwards if they are real
Yeah, but planet's that pass by based on some unknown, compound, transience could exist and we would have little means of detection if positioned juuuuust right. That being said, it probably doesn't exist because of the irregular orbit, we probably "lost it" at some point if it ever existed in the first place.
Well it was obviously Galactus....Destroyer of Worlds. Planet X was sited by the Silver Surfer many decades ago then was consumed by Galactus. The evidence is in the Wakanda public library. ;)
What they will call Planet 9 after they find it is probably what people call Planet X right now. I'm not sure that it will be a planet when we find it. I would imagine that if it gravitationally dominated its orbit, we probably would've seen it by now, unless it's inside the Oort Cloud.
we dont even know if we exist..this could all be a simulation. And if it is found could that also be some made up story to fit some paradigm ?
Planet 9 is very interesting to me. It seems impossible that there is another planet we have never seen. But numbers don't lie
What a packed Portland crowd!
Excellent discussion but how about Pluto. The more they discover the more it fits the definition of a planet.
pluto is and have always been a planet.. no matter what they say..
and finally they'll catch up with planet Nibiru
I thought it was Nemesis?
I think they should stick with Roman/Greek gods for consistency
I am not nibiru
@@shawnh8498 nemesis is the hypothetical binary star of our sun
I didn't understand a thing but still loved it
I’m in love
She mentioned how Pluto circulate (in a ellipse movement) around the Sun never really hitting Neptune, but she never mentioned if Planet 9 which moves in the same fashion ever hitting earth. What you think guys?
It would have to cross right into the inner solar system to even come close..
The computer simulations on which Planet Nine is based all indicate that at its closest position to the inner solar system the distance is several times that of Pluto - about 200 AU. The most distant point is supposed to be about 1200 AU. All hypothetical of course. ''Hitting the Earth'' is just a fantasy by people who have seen too many silly Nibiru CZcams Videos.
They found an anomaly near Uranus. It's a nee moon named dingleberry
Right 👍👍
Pluto will always be my ninth planet and no one can take that away! We lover, Pluto!!
Interesting that her orbital pattern for Planet 9, 2012, VP 113, looks like an old Sumerian depiction, what a coincidence?
Wow, your right! I hadn't even noticed. I don't believe the sumarian myths but that is pretty interesting.
@@shanewilliams5326 my I ask why you don't believe the Sumerian myths? I don't believe them either
Spirograph
there is a part of Sumerian mythology that basically describes the creation of the solar system, so if instead of looking at it as just deities and mythology and you start looking as a narrative, a way to convey astronomy through a story and explain how the solar system was created, you'll see that the issue is not the mythology, but how most of us have been interpreting what it meant for them.
when we make a cartoon for kids and use characters to explain how the cells inside our body, does it really mean we believe we have cartoon characters inside our bodies? so maybe whoever created it was not a primitive being that actually believed the planets were gods and deities, but he was simply packing astronomical knowledge through a myth because some of the things of the Sumerian mythology are too accurate to be just by chance.
Not conincidence,but scientist will never recognises old scriptures and knowledge.
Ancient india had vedic knowledge documents navgrah (9 planets) since more than 5k years.
Buddy the sun and the moon were the nine planets.
@@agrimchaudhary6703 no don’t tell him the truth , he wants to think ancient indians knew everything and westerners stole it
ancien civilisation had a great knowledge about astronomy, they even new the speed of light and mathematics and many other things!
nice pyramid and horns in the intro :)
Ted talks are like episodes of law and order every single one is written with the exact formula lol
Predicted decades ago by rocket surgeon & astro-ilogical genius Ed Wood in his masterpiece “Plan-et 9 From Outer Space.” Tor, Vampira, Bela Lugosi gave their all for drugs, science and art.
I still have my "It ain't rocket surgery." T shirt.
Nice..talk
My proposal to the IAU is to name this new planet 'Renu' when it is found!
Galileo didn't discover the heliocentric solar system! It was Nicolaus Copernicus!
Abie U K it seems that in order to be brief she gives a very truncated history of the model of the solar system. Copernicus can't even be credited with "discovering" or creating the concept of a sun centered solar system, Aristarchus is known to predate Copernicus's model by quite a lot of time (over 1000 years) and it is doubtful Aristarchus created the concept.
Galileo was a known proponent of heliocentrism and is credited with discovering the first objects to orbit other planets and provide some of the first empirical support of heliocentrism.
Kepler almost always seems neglected, and imo he is as just as important to the heliocentric model as any of the others mentioned above.
Basically, what I am saying is that you can't hang too much on this very truncated history and it is only really mentioned to support the rest of her points. Also, heliocentrism is an incredibly outdated model superseded by far more complicated cosmological models and hasn't been considered "correct" for over 100 years
gumbilicious1 yes it is true that Aristarcus, and even Aristotle had a philosophical doctrine appertaining to the heliocentric model, but Copernicus was the first person to mathematically find the positions of the planetary bodies in the model. As for the philosophers, though they were in part correct it was, in essence, a guess.
And yes, now I get that she only mentioned Galileo for simplicity.
Abie U K I am not trying to be argumentative, but only to make a valid point. Your stating that Copernicus's contributions are a defining point of heliocentrism is as arbitrary as this speakers attributions to Galileo.
It is only a statement of popularity that makes these names mentioned. There has been plenty of instances in the Indian and Muslim worlds of heliocentric advocacy
Copernicus's himself was influenced by a philosopher of recent time advocating heliocentric views
Let us not also forget Copernicus's models were highly flawed and not taken in by popular consensus in his lifetime. Contributions from Kepler and Galileo were required to even make Copernicus's model a contender
So for these reasons, I feel heliocentrism being attributed to Copernicus is just as flawed as most of the abbreviated history she states
Galileo was the first to look up at the sky and confirmed what Copernicus predicted. :)
I believe the Sumerians and other ancient civilizations had theses models too. It took us a while to figure it out tho, not just one man
"what does it mean to find a distant large planet? Well, it may make horoscopes more accurate, finally" 😁
Use Google to look up what a horoscope is and then you will understand the joke.
Sounds good
This woman is the strength
Narrow annulus 😀
nice
We have a planet 9! Long live Pluto! 😂
No me
It’s all over my head.
Hopefully if its there its something new entirely with a different composition that contains rare matter or explain missing gravity. A piece of the puzzle , its ok to hope
"The planet earth nourished you, Developed you in every existent way and then received you in her arms when you die, that is why it's called Mother Earth."
Explains why nature can be so moody.
Ah, now I know how all these TED speakers remember what to say :-)
Nice
we need more space telescope measurement and orbiting measurements of the planets to precicely predict their paths and quantify the other objects in the solarsystem.
we need to know the planets positions with high acciracy..
They heard we have taxes so changed orbit....
I wonder if the orbits follow the golden ratio and fibonacci sequence?
I have wondered about Fibonacci in the cosmos for a while.... Looking at spiral galaxies I think you are correct.
we have been so fixated on the solar ecliptic for so many years that we have made the mistake of thinking that all such encounters and objects must be found in or near it. The idea that the sun came from a large molecular cloud, with many other nascent G types, suggests that any captures then or for some period after the cloud dispersed or was left, would seem homogeneous with our own native material and could come from any vector at all, align itself any way physics thinks looks best, and confound us with its eccentricity. Not all material we find need have originated in our singular stellar womb.
There is more knowledge and research and theories in the comment section than there is in this video … cool stuff all round
On The Horizon a Terrifying New Star.
The Crickets Have Stopped Their Singing...
We can't even spot a planet in our solar system but we find a lot of planets outside of our solar system everyday....lol
The Buss we do not see the planets in other solar systems, we measure their effects on their star and estimate their characteristics....
finding the star is the easy part... it's that shinny thing...
space is huge, even within the solar system, it is quite easy to not see something by just not looking in the right spot at the right time...
@Phil What I love about this process is (1) that we know nothing about sun spots on these other stars and if THEY cause the dimming and (2) just what are the odds that a planet's orbit will occult that star? That the plane of orbit is exactly lined up with our solar system? I think it VERY unlikely they are seeing planets with that method.
I'm with you The Buss.
It's completely laughable that science continues to drop finding of "planet blah blah that's 4000000000000000000009990 light years away, could be the right temperature to make ice cubes" yet they can't figure out what comets are or even how gravity works.
@@ronrothrock7116 We can observe a pattern when a planet passes in front of a star. It would be quite unscientific to observe a star that dims a little bit and assume it was a planet without seeing it happen over and over again and analysing the data very carefully. Also, it would be a bit difficult to have a star perfectly aligned with ours in a way such that we can't see the orbiting planets. Most of the time they would dim the light of the star from our perspective. And even if they don't, if the planet has enough mass, we can "see" it by observing the gravitational effect of the planet on the star.
It all boils down to ignorance. Don't make assumptions if you don't understand how something works. Try to answer your own questions with facts. If you can't, ask an expert.
Same way we know more about the surface of the moon then the depths of our own ocean.
Methodology and limits of technology.
Science, my friend.
I don’t believe she knows how funny she is. Excellent presentation. Thank you.
Namaste have a beautiful Journey
heather hill you also, peace, out.
You too
The Sumerians then, had it right 5,000 years ago?
yes they did! everything they said is being proven by current science.
If they couldnt see it, and couldnt see other planets, then they had no basis for the belief and it was a lucky guess, which is not the same as correct.
@@TazPessle Lucky guess? read the ancient history buddy and learn something.
@@JJ33438 the problem is there is no evidence for the Sumerians tracking these as yet undiscovered planet(s). And no technology for them to have seen these objects. So how is it not guesswork? Or is it actually a half-fiction of their religion mixed with observation? You'll have to point me to some credible sources to rehabilitate the assertion that they actually knew about nine actual planets.
@@TazPessle Read the various translations of the Sumerian Tablets. Sitchin did a great job of translating but there are other translators and they are all quite consistent in translation. and Brandon.....these tablets discuss advanced technology that we do not have today. We treat all ancient writings as "religion" whereas they are in fact historical writing...just like the Bible which I have read cover to cover. The Bible is in agreement with the historical facts of the Sumerians.
I can see Pluto coming in and smashing into us like a big F U
Can't wait for that
Maybe they could just do some sort of planetary radio radar and scan for objects with a low energy level and signature? I think the speed of light is fast enough that a reasonable sized object would remain in line for the period.
Nice speaker
Ancient Indians know about NAVGRAH (nine planets)
