Do Planet Nine and Planet X Exist? With Amir Siraj

[@animistchannel]

I like that Amir can shift between hard/defensible data and speculative possibilities without having to make a hundred excuses and disclaimers first. He can just have a perfectly normal conversation and dip into various realms of thought with the appropriate degrees of rigor for each kind of consideration, and this is SO important for the future of science. Yes, we need super-tight discipline on what is calculable and determined to be "real" confirmed science/technology, but we need people who can put the marginal possibilities and potentials into a casual, accessible frame of reference and simply say "Yah, it would be cool if..." or "It could be this or that, and I would love some of these..." without building a siege wall of exclusionary rhetoric. It IS okay to wonder and dream and contemplate beyond what is already established, so long as you can still tell the difference in the end. That's who ends up finding ways to advance the boundaries of science to whole new realms and levels after all. BTW: I'm a little annoyed that you didn't ask him what music he's been working on lately, who his favorite composers are, or how "the art of the frequency" drifts into or influences his contemplation of the cosmos. There is a relevance to such things. This universe is made of waves... force waves, gravity waves, EM waves, acoustic waves, even time waves. One thing resounds with or harmonizes from another, and so all the cosmos is fulfilled with these musics, from the tiniest scales to the longest :)

While 4k/8k is mostly useless for regular PC work/TVs, due to our visions physical limits; astronomy is the epitome of showcasing where pixel count/resolution matters 100%; and consequently were some of the most advantages would come from for significant advantages. Take hubble ST, Sedna was only 1 pixel in it. Newer space telescopes, other dwarf planets/TNOs are only 10-50 or so pixels...including the atmosphere/moons. A resolution increase of say 50x would mean that MUCH MORE detail can be observed from the same size picture. When you get that, you can start to get more precise details about atmosphere, structures etc.

[@andyoates8392]

@@djdrack4681 great information 🤓💚♾️

[@GreySectoid]

Excellent interview, thank you guys!

[@cykkm]

Up to 4:20: Amir's objections are totally valid, but there is another possible origin of a massive planet in the Batygin and Brown model that needs to be explored/rejected: a planet half-ejected from the late early Solar System (v. the Oligarch Planets hypothesis). This may be perhaps the most likely explanation of its origin. But an alternative theory is a boon in any case! We'll find the shucker sooner or later, it won't hide from us! :-) ~25:00: I'd rather sent a truck-sized autonomous robot with an on-board lab using an electric propulsion drive. We can surely kick pieces of foil with a laser there to arrive in two weeks, but what and how are they going to send back? 34:00: An excellent idea! An apple-sized BH has extreme tidal forces above its horizon, and will atomize just anything, from a grain of sand to a comet-nucleus, in the literal sense-into individual, atoms, probably, albeit within a small volume (but much larger than a stellar-mass BH relative to its size, maybe 10³ to 10⁵ apple radii). If there's enough free dust supply out there of just any size, it will capture, disrupt it and constantly accrete. It's very unlikely a primordial BH, but if it is, that would be just what Amir said, a discovery of the century, and on a low budget. I'd certainly try to work out a more precise model of what exactly we would be looking for. P.S. John, you have a bandpass-limited white noise in background, the source is probably the mic. My to-go sound restoration program for such mishaps is Adobe Audition, but many other sound editors have this function.

The thing with planet 9 that makes it even more fascinating for me, is that 10 years ago, scientists were saying with absolute certainity that the mere existence of a 9th planet was ridiculous and in the realm of conspiracy theorists. That we would have detected it by now with certainity. Now, for the past couple of years, it seems like more and more scientists believe on its existence... Makes me wonder what other things are "ridiculous" nowadays and will be proven true in the future.

[@manachromeYT]

[@ApocalypseofMichael]

Have you heard about the "Sagittarius arm" of the view of the milky way? It isn't an arm of the milky way. It is an arm of another galaxy that is colliding with the milky way. It's also an Infrared galaxy. It looks out from the core, down under the galaxy and then comes up through the milky way where we are. We may be from the galaxy Sagittarius. It also helps me with Velokovsky, planet 9, the local bubble, the myths of different star systems, our obsession with precession, stellar motions and planetary motions in history. Perhaps even shows why we didn't have "Blue" at some point. I could go on with this. Please look into it. Mind blowing!

[@amangogna68]

Great video and information !

[@pauljs75]

I think it would be neat to send out some kind of daisy-chain system of deep space probes where the next in the series also functions as a relay node for the one ahead of it. That would allow for an interesting amount of data to get passed along, without having some kind of ridiculous power requirements. To do some deep space exploration in the solar system, it seems like it'd make for a neat approach in finding stuff like possible extra planets or something like a brown dwarf.

[@EinsteinsHair]

NASA recently tested laser communications in space. That might have a tighter beam and need less power. I don't know any numbers on that. You will not just need one line of probes to find things. If you send out 600 lines, like spokes on a wheel, just to investigate the plane of the solar system, not the entire sphere, the spokes will be 1 AU apart at 100 AU, and 10 AU apart at 1000. An object between two spokes will be at most half the distance from one of them. Still, 5 AU is the distance from the sun to Jupiter. Could they detect a Mars at a Jupiter distance in the dark outer solar system? You probably need more probes.

[@EnneaIsInterested]

So, there's one topic I haven't heard of - If we could send out Breakthrough Starshot-type probes in all directions, we could 'quickly' categorize the Oort Cloud.

If this is the case then expansion out has many more possibilities.

the very idea that a planet is ''an object that clears its orbit of debris'' I find to be quite preposterous when you get to distances so far out that orbits are hundreds of years long a planet the size of Jupiter with a 300 year orbit would never clear its orbit of debris, the distances are just far too vast

ARGUMENT: 'Primordial Black Hole'....Is NOT a black hole. Its a singularity to be sure, but current stellar mass BHs are post-stellar remnants: IE they HAVE TO come from a star. Primordial (AKA from very early universe)...would not have been 1 star = 1 BH. interstellar gas densities point to direct collapse models. If it doesn't go through an 'stable' star phases, and becomes a singularity...then I'd call it a Primordial Singularity. We haven't observed 'micro black holes', they're still theoretical; and I'm not sure they fit into current cosmology. I don't expect sub-stellar mass black holes to really exist outside the most exotic of origins...So, it seems to be a non-serious talking point to think there could be one nearby. Its like the idea of an 'inactive' Black Hole...where after X mass, it stops consuming material: this also doesn't add up to being a real thing based on current models and physics. For one to 'turn off' it would imply ANOTHER FORCE at work; one within the event horizon, that mediated how much the BH could consume/how massive it could get... ^^^This is directly contradictory to the very notion that a stellar-mass BH can 'evolve' into a intermediate mass BH (via BH mergers mostly), or consuming A LOT of material over billions of years. IF they could 'turn off', then many would...but since their gravity well is still very much a thing, that'd be 100% impossible. IF nothing could pass the event horizon (cuz it was 'full') It'd basically 'pile up' around that boundary...creating some stellar amalgamation of a star & BH at same time...Which would have very distinct characteristics: and which we haven't observed yet: giving evidence they don't turn off.

[@djdrack4681]

Why would a low incl. matter? Most stars fall on nearly same incl. cuz of accretionary physics of protoplanetary discs. that says nothing about how a star's gravity well is spherical, not football shaped. I can see low periapsis/closest approach for a captured exoplanet/rouge, IF it was very low, then it'd either disrupt the native planet's orbits Or get kicked out cuz of the strength of N-body affects on its highly parabolic trajectory, preventing it from being permanently being captured. Still. that would imply, even with a low periapsis, that it doesn't get affected much by the gas giant's own gravity...Which is fairly improbable. Odder STILL, I haven't seen any modeling that strongly disproves current theories that the number of rogues is 5-10x+ the galaxies star population. Some support lower numbers like maybe only a 1:1 ratio, but the ones I've seen have issues arguing exo-oort cloud interactions, and how an exoplanetary config could be maintained in the denser parts of the galaxy or during very close star passes (0.1-0.5ly).

[@djdrack4681]

I PREDICT: Another type of 'capture'...Accretion disc capture. Rather than capture an exo/proto/dwarf planet: If a older star passes close by a newer system, it could steal enough debris from the accretion disc (of the 2nd 'new' star), which would be at kuiper-belt distances (in the 1st system)...THEN over 10s of millions, maybe 100s, that debris accretes on its own in the older star's system...forming a planet. Pulling from an accretion disc, on its outer edge...is tantalizing, bcuz of the makeup of it. You have a high % chance of capturing a lot of comets, water/other ices, Methane, etc....while still getting a lot of rocky material (from the lighter meteors/small rocks). SO the chance of getting a Earth/superearth sized, oxygen/water ice rich planet is not insignificant %. COMBINE THIS: With the debris/dwarf planets the older star's own kuiper belt/oort cloud had...and you can see how you could acquire not just 1, but maybe even 2 or 3 Earth/Mars sized planets far from the star (even compared to Sedna). For it to be remotely habitable, it'd need a lot of lanthanide/actinide elements, and iron/lead to keep its core/mantle hot. Iron and Lead are both important cuz of their place as 'the most stable' transition metals...Which helps to ensure they don't decay to lighter materials (and migrate to surface permanently, cooling the planet).
