Thank you Konstantin for providing such an engaging, fascinating, and humorous presentation regarding planet 9. I have really enjoyed hearing your interviews about planet 9 via audio, but had not watched a presentation previously and now have an exponentially better grasp on your theories because of the visualizations provided here. Keep at it and I look forward to hearing your name over the coming years and decades and am confident your work will land you in the annals of planetary science history.

One of the best scientific talks I’ve ever seen. (Wipes off cookie crumbs from my t-shirt at 1:00 AM)

I watched this lecture after watching Mike Brown's lecture, Konstantin's project partner. which includes descriptions of a constant language difference struggle. Their partnership and friendship must be joyful. Their project a beautiful example of analyzing the last decade's astronomical data, making predictions, and with existing instrumentation, they are looking for confirmation. I sympathize with the individual having the office which separates these two at Cal Tech.

This guy is a great public speaker. bravo!

This shit sets my mind on fire! If only I were young. I remember sneaking into the university in town to look up peer-reviewed papers, as a junior high schooler, using a card catalogue. If only women of my generation weren't only taught how to keep a cheque book and cook beef stew. What I wouldn't give to be in Dr. Batygin's class. You guys are so blessed beyond belief! I didn't have a choice, but you do. Don't let me down!

Very clear, easy-to-follow presentation that never feels dry thanks to his great way of presenting this stuff. It kept me tight to my screen from start to finish. Magnificent job!

Excellent presentation, really smart people have interesting insights.

Thank you for this very fine, well planned presentation. You are very good at keeping listeners interested.

This is so fascinating to me!! This man explains everything so well!!! Really like this guy, and he looks so young!!

Came here after Lex's interview. I also picked up The Black Cloud based on Konstantin's recommendation. Freaking loving it.

This is probably the most pleasant presentation i have ever seen! Very well done!

Fantastic lecture, and humorous too!

Great presentation! I really enjoyed it.

Thanks for an interesting and thoroughly enjoyable lecture.

One of the most interesting lectures Ive heard in a while.

Awesome presentation.. a nice blend of science and humor.

Wow! That is one of the best presentations I've ever seen! I bet his students love him

very entertaining! i want to see more from this guy.

This guy is actually funny; not just like, _TedX slideshow clipart pun_ funny. Fascinating lecture 👍

After his interview with Lex Freidman this lecture is an amazing revelation.

Fantastic lecture, well delivered.

Excellent Lecture. I must get it to my Astronomy Club members.

Absolutely well done and definitely keep it up!!! 👍👍👍👍👍

Thank you very much and all the best!

We are looking for something like ourselves. Something consistent, yet forever changing.

This was really fascinating.

Somewhere out there Konstantin is still being introduced.

Awesome lecture

Ok, I barely understand anything math and science. Science wasn’t difficult, but in a private homeschool program, I never had science classes; just some text books on basic science, no experimenting or anything hands on. Math though, math was always a challenge...but not challenging. I know, that may not make a lot of sense. Math was a constant struggle because I didn’t have teachers for each subject. Anytime I needed help, I would be told to figure it out. I’m not ignorant about math; I know the basic functions of math, I just never was able to grasp it. I don’t think I’m dyslexic, but the textbooks I had to use would have a page of simple instructions and examples, which got me started out ok, but as soon as that little sample page was done, the following pages exploded into massively complex problems that the previous examples didn’t explain. I simply could not grasp any of it. But looking back on my life, I’ve discovered that I have always been a hands on person. As a kid I would tinker and take things apart and reassemble them. Most jobs were all hands on training. Never attended college or trade schools, but I’ve worked in hospitals, dialysis clinics, surgery centers, diesel mechanic, and ultimately LE where I was medically retired in 2013. Now, I’ve had extensive training for LE, but honestly, I just took a test, was 6th out of 250 applicants, got hired, and then after 8 months working off in house training, I was sent out for classroom and tactical training. I taught myself to play the drums, kind of learned the piano, bass/acoustic guitar, singing, mix sound, and pretty much anything music. Learned how to wrench on cars out of necessity more than desire due to not being able to afford a repair bill. Learned how to fix things around my house for similar reasons. I know I’m not the only one who’s done the exact same thing...but my point to all of this is, had I been taught by people such as Konstantin, I most likely would have been able to grasp math.

Does Planet 9 have any relationship to the comet - C/2019 Y4 (ATLAS) - currently passing through our solar system?

Scientists are entertaining these days :-D Excellent presentation!

1) Does magnetism (gravitational pull) vary with the temperature of the heavier elements? (Also something to do with density). 2) Now I know how sometimes, when I get a bolt cross-threaded, as it heads into the engine block, it has everything to do with Planet 9. I appreciate having made this determination on the basis of planet 9. What are the odds that any other star/planet system are just like ours. It is pretty cool that Planet 9 can be determined to be the reason that our sun has a 6 degree inclination, or whatever those degrees off of Zero. Some one told me that every thing is in the Orion Constellation. AF

Very entertaining and educational. Thank you Konstantin. My high school physics students have enjoyed it. Been playing it since 2016. Hope you find it!! I think of chaos theory and say to myself that it is remarkable that these odd asteroid Kuiper belt orbits showed up in so many of the simulations.

Fantastic presentation 👏

I can accept how the position of a new planet can be found from the perturbations of the orbit of the previous planet - but what were the techniques, so long ago, for _measuring_ the perturbations of the previous planet. It's not as if it did an orbit in the meantime - it only moved a little bit, and in that small distance, they already had determined where it was vs where it should have been. How?

Wow. I am looking at orion right now. Dec 29th 3am. Had my eyes have huge sensitive detectors built in behind them I'd be looking at it! Do find it Doc!

Can kepler-2 observe 20 degrees to look for this objects ?

Excellent presenter. I first noticed him on Lex Fridman. He has a way of humbly delivering knowledge while keeping one's attention with humor. Love it! Adore him!

May I ask if and where I can get a transcript of this video, especially the introduction by "Dave." I would give everything to have a mentor like that, and to be introduced in the way Professor Batygin was.

Great intro

Great lecture on the mystery sorrounding the ninth planet. Wonder of the planet has been found? From a retired physics teacher

Nicely put together

great presentation

just came here after wathcing his interview on russian youtube channel Вдудь and i did not see that coming how really smart and comical he is. Why i havent heard about him before

perfect talk, funny and persuasive, after that I can only believe anything he says....thank you

What happened to the q&a?

That's amazing. How many people have scanned the sky with their naked eyes and observed the belt of Orion, as if it was home.

Awesome. Great dude.

Great Video!

Great Presentation, once again!..... Is there any work being done to actually map Our Local Group Birkeland Electric Field Pathways?

Hello I wanted to ask you a question can Voyager 1 and 2 spot planet nine at its current position

@48:18 did he say "current?" Because if you aren't considering "currents" (as in electrical / Birkeland currents) then You Should Be !!!

You nailed it boss.

Where would it have been about 12500 years ago?

I am so happy to find him on YT, an outstanding speaker, watched all the videos with him. Wish him luck in finding this 9 th planet

Hope to see more of this guy, really good.

Excellent presentation

This kid came so far since slaying that vampire gang in Santa Cruz. Remarkable.

BRILLIANT!!!

Very clear presentation of data. Gifted researcher indeed.

Planet 9 or Planet X or nibiru is out there and it comes around to the near earth elliptical orbit every 3.600 years and is Due to come back in 2036 or 2046 something like that it’s coming from behind the sun but should be able to know for sure that it’s there soon.

Great presentation. Any new developments? :)

If he sings "Pop Goes the Weasel" at the end, or plays a conga drum, I'll bust a gut.

Awesome bro.. Congratulations on the discovery!!! Um, I am just wondering, how fixed is the orbit? Can it be longer like 24 or 25 thousand years?

A great guy !!!

So how do you by part the history of kemetic sciences

Make the Solar System Great Again.... Hysterical!!!

Love this guy he was on Veritasium

Вдудь раскрутил космос круче чем Рогозин!!

So what is the status of the search? Any news?

He is a good speaker, I cant go out When He speaks. He is very good into his interactive process.

If planet nine have aligned the eTNO over billions of years, and then say another star "captured" P9 from the solar system, how long would it take for the eTNO alignment to destabilize? (That could be a reason we've not seen it, if it was lost 10 million years ago for instance.)

Very very good🙏🏻🙏🏻🙏🏻

Great job, best luck finding the planet. Very entertaining and interesting lecture.

How can i get involved in helping with science events because im an event planner this is what il do forever

So nice presentation. It was nice to watch it, enjoyed watching... Thanks. And i am sure, Konstantin is very talented. Please go on investigation. Btw, I am watching you from Russia

One thing I noticed in your simulations, that you kept the orbit of Planet nine constant. it's orbit must be deviated during 4.5 billion years? If Planet nine deviated or affected the orbits of other bodies then other bodies must have had affected the orbit of planet nine because of large solar bodies or planets like Neptune?

Thankyou. Your Wise.

Question: In theory!....Could the eventual proximity of this planet 9 to the sun affect the rotational angle of the Earth?

From the perspective of an interested bystander, (factory laborer) it seems to me that the Orbits of these distant bodies are responding to the entire solar system as a point source of gravity as one of the foci of their orbital elipses. Could there be another field of gravity drawing the many elipses of their orbits to that region of space where their other foci seem to gather?

This could explain the polar reversals every 500,000 to 700,000 years, the magnetic North Pole moving into Siberia & everywhere else, global warming as a result of the loss of our Van Allen Protective Shield. Taking all the planetary & solar angular planes in computer analysis Will indicate where to look for the approach of Planet Nine.

I like the sound of CalTech

Interesting lecture, fun lecture

Could it be a miniature primeval black hole causing the gravity pull instead of a planet?..

so, it's near orion, can I find it with my 8 inch dobsonian ? that's my telescope not my 8 inch dongleonion...

Awesome lecture! "Is DR30 a street drug?" :-)

Right now we found Planet 9. Maybe in year by year ,we have another 90 soon. They are coming to us closer day by day.

Is this going to now explain Vortex math

The greatest “Bad” movie of all time by the great Ed Wood

Good stuff

Hello from Kazan!

Why not call planet 9 Pluto? It will go very well with the explanation of Pluto in Astronomy as well: A mysterious planet that is hard to fathom (like Scorpion it represents). These Characteristics were falsely given to the old Puloto. Now we know that small dwarf planet did not deserve it. So we can call old Pluto: Dwarf Pluto (or maybe Pluto wants to be:), or something else).

Astronomer and stand up comedian 2-in-1. Great work!

The resemblance of his charisma with that of Feynman's is uncanny.

More please

Huh. I missed all the visuals. It came on by accident, through my Bluetooth while I was driving. I almost shut it off. But I couldn't. It was fascinating! Quick hour! I like how they gave credit to those who weren't there that contributed to this finding. "Everything has to do with planet 9"

Awesome

Gravity or frequency?....

I have a question! Assuming planet nine does exist, is it more likely that it's a rogue planet, captured by our sun, or a native planet, that formed with the rest of the solar system?

what about oort cloud?
