Wow, I found a jackpot here. Self taught astrophysics enthusiast and I've got to say that the popular science news and culture on the internet is garbageeeee. Thankfully, this made me seek out college level lectures and some times these dumbed down Public talks with no math and no big words. In any case, thanks a lot caltech

[@CaltechAstro]

Glad you're enjoying our content! We've got lots of lectures and Astronomy on Tap talks from the last several years to keep you busy. Hopefully more stuff on the way as well. Thanks for the kind words!

[@skel8tor]

(I just watched the 2016 lecture) First I wonder if Planet 9 could be the cause behind Precession of the Equinoxes? I'm reading Hamlet's Mill at the moment and laughed hard when he said that Sedna lived in an Ice cave "beneath the ocean"...and had "5 fingers cut off". Perhaps original Sedna was a star who spent most of its processional cycle below the horizon, and new Sedna is the object described in this lecture. (however this is a very -Hamlet's Mill way of thinking. Second. I wonder if the location of Planet 9 could be predicted through analysis of Myth? en.wikipedia.org/wiki/Hamlet%27s_Mill Thank you I really enjoyed this, sad to find out that Planet 9 hadn't been proven during the 3 years since.

They say the universe is still expanding from that explosion but answer me how do stars sit still

[@jameywc2]

Actually space is expanding and speeding up. Do you know anything about the higgs field? Stars stay still? How to explain to anyone who has no clue except "God did it" is a waste of time.

[@GBFS2011]

Does anyone know whether planet 9, when at its closest distance to the sun (c.5000 years ago), had an impact on the Earth's orbit or environment?

[@GBFS2011]

Or, more unlikely, was recorded by early Mesopotamian astronomers?

[@CaltechAstro]

It didn't. Planet 9 is roughly 6 times the mass of Earth, and about 200 AU from us at closest approach. For comparison, Neptune is 17 Earth masses and 28 AU from us at closest approach. Even Neptune is way too faint to be visible with the naked eye, or to affect the Earth in any way.

[@GBFS2011]

@@CaltechAstro Thank you

[@davidpnewton]

The only way that it would affect Earth is it it somehow gravitationally perturbs a body and sets it on a collision course with Earth. The chances of that happening are vanishingly small. Jupiter is far, far, far more likely to do something like that: it's much bigger and it's much closer. However given how big space is even Jupiter is very unlikely to do something like that. Jupiter's much more likely to suck said body in with a repeat of the Shoemaker-Levy 9 impact from 25 years ago. So to a very good approximation it has absolutely no effect on Earth.

[@jari2018]

@@CaltechAstro So its 6 masses now - it should ? then keep it premordial helium in the athmospere but loose the hydrogen .

[@ivornelsson2238]

I don´t think there is a massive Planet 9 out there. All motions in the Solar System origin from its formation and this formation shall be included in the explanation of the pre-conditions and the factual formation of the Milky Way galaxy, around which the Solar System is an integrated orbiting and formative part. The formation of the Milky Way follows the rules of electric currents and its perpendicular running magnetic field working on the plasmatic stages of cosmic clouds of gas and dust. Such clouds are assembled by the ATTRACTIVE electromagnetic polarity to form stars and planets with orbital planes perpendicularly to the galactic disk plane. A running electric current induces perpendicular magnetic fields which again induces perpendicular electric currents and magnetic fields etc .etc. thus making it difficult to determine the initial cause of the elliptic orbits in the Solar System. My short take on this, is that the initial cause to elliptic orbits derives from the Solar System dispersion from the central galactic formation - a centrifugal effect from the galactic center which additionally and logically explaines the observed galactic rotation curve as well.

48:25 "It [Planet Nine] is about 3X further than Neptune.....Neptune is at 30 [Astronomical Units] and Planet Nine is at 300 [Astronomical Units]" Ok something is not right here, maybe someone can help me to understand the good professors statement.

seems to me,planet 9,niburu,is where we came from,or were engineered.as they are our fathers,comes around every 10 k,or so.in ancient texts,there are 10 planets,not nine.pluto used to orbit jupiter or saturn,long time ago..why dont these dumb brainiacs.find the real truth from the ancients,instead of trying to get grants for being the first.which,they are not..even niel de grasse,wont admit we,ve been here before,have engineered dna,or there are ufo,s,,as he,d lose his station,in life...eh...who cares about unit,???.care about the real truth..we are kept dumb for a reason ..!!..

[@jgottula]

Well, based on the numbers I’ve seen elsewhere about the predicted orbit of Planet Nine, the absolute AU number he gave sounds right, and the relative multiplier he gave just seems to have been a mistake. So I’m pretty sure he just misspoke when he said 3x Neptune; likely he meant to say 10x but was just mentally distracted or something.

Hello Caltech Astro - very interesting presentation, thanks for posting to You-tube! I have not studied Astronomy, but am generally interested with an open mind. Just watched the 2017 Berkeley presentation before this one,and hoped 2019 had been successful. Q: After seeing the P9 cadence of 10k to 20k years, and reading "Isaac Theaker's question below, I was pondering if P9 may be involved in "Divine/Great/Platonic"-Year long cycles; and "Heinrich Events" also come to mind - surely a wild hypothesis, with need for sufficient evidence. Or just a mix of Apophenia, Patternicity and Agenticity :) First, of course, we need to find Planet 9 first - good luck with that for 2020!

[@tanksyber3237]

It's already here Start searching for individual sightings thank me later Prepare b vigilant

[@stevelenores5637]

Planet 9 is hiding behind Pluto. It will stay hidden until Pluto is declared a planet again. - Signed Pluto

[@RaymondPriester-jm5vx]

OK if the big bang created everything from an explosion going outward why do stars stay still while everything orbits around it. Makes no sense admit it.

[@CaltechAstro]

The rate at which the universe is expanding is reasonably small on the kind of timescales and distances that we're most familiar with: year to year and the location of the planets and stars in our own galaxy. It only really gets substantial on longer time scales and larger distances, like the distances separating distant galaxies. In fact, the forces from gravitationally bound systems, like star systems or like galaxies themselves, works to counteract against the expansion of the universe on those scales and inside those systems. But objects separated by large distances that aren't gravitationally bound, like two galaxies separated from each other, cannot have gravity correct for the displacement from an expanding universe, and so the space between those galaxies continues to grow with time. But the stars within a galaxy, like in our own milky way, which are gravitationally bound to the galaxy, can correct for the universe's expansion, at least at this stage of the universe's growth. I hope this helps to explain why the stars do not appear to expand away from us within our own milky way, but why we see distant galaxies moving away from us.

[@RonJohn63]

25:37 That's a really profound statement about all of humanity... And I feel a bit bad for Kathryn Plant getting no questions.

[@CaltechAstro]

Yeah, we tend to get a ton of questions about alien life when we have lectures on exoplanets. At least the public is excited, and they're right to be--the next generation of telescopes might be able to detect signs of life in exoplanet atmospheres.

[@indivestor]

It was a about as profound as a dog barking

[@stephenallen8671]

Y is it some experts say planet 9 exists and some.dont. kinda weird. They can't all be experts as half of them must be wrong. How do we believe a word they say when they say opposite things

[@CaltechAstro]

Scientists are working at the boundary of our knowledge of the Universe. Some scientists have hypothesized that Planet 9 exists, whereas others have hypothesized that it does not, but the evidence is unclear. Just because they disagree on the interpretation of the data doesn't mean that they don't know anything, it just means that the evidence isn't conclusive one way or another. Let me put it another way. You and your friend are inside a house and hear a bang outside. Your friend thinks it is thunder. You think it's a gunshot. Who is right? You need more evidence to conclude on who is ultimately correct, but it doesn't mean that both of you are stupid or uninformed for making different hypotheses.
