It's all 'bout da bass, no interplanetary travel. (Meghan Trainor – All about that bass – a song about planetary accretion discs and coming of age for planets.)

Anton, your video on the updates of your planetary science is really interesting and refreshing! Thank you.
And we are constantly told to "trust" the "experts" and the "science is settled". We don't know half as much as is claimed.
8:33 "…but never something similar to the solar system.."
Why do we assume that there should be something similar to the solar system?
It would be rather like finding two people with identical DNA. Wouldn't it?
O fabric's 😃😄😁😆😅 5 Smile's.
I believe planets form in a super nova..not from dust
Is it possible to rule out the possibility that this is a wandering planet — ejected from another system where it originally formed — that has been captured by this star and has simply accreted "primordial" material from this star's accretion disk during the inbound journey after which it was captured?
Bro, when are you jyst going to come out and say 'yes! Its aliens!' 😅
They can't rule out it was captured?
God created the heaven's and the earth.
Never forget that.
It could have been a rogue Planet just hanging around and got caught up in the gravitational pull of a Sun.
Your not intelligent. And what you do helps stupidiafie the general public. Hope its monitaraly worth it for you friend.
When we look feom a other position toward our solarsystem and interacting in a way that we mistace the inerhelio as totoydal coronal we olso see onley gass planets
And so i so without plasmoidal orbitals there are no tangebiletys to hold the discks togheter
Than if debiation risses long inoff the plasmoidal orbitals can manivest planets way bevore the plasma philemental graventaitional countering in to the container behind the toroidal coronal layer as the metakontainer where the filts behavieures tat becomes tangeble as the son is witing in bilding stages
If i lower thention disks disappear do to a lagg of diamagneticle pressures towart positioning of the population of the solarsystem around thos stars
Plus diamagneticle sun container opens up inehelionova whay you see onley gass giands in som stares there solarsystems 👀
And onn and onn and onn.
Go look for solarsystems without stars for a chaince onley don't play when you see thame "nobody expected this nobady know our wat ever
Just place the ice rings above the opserver tool(telescoop and radia scoop around the disck as the opserver tool not around the top around the bothem where the translations are in to/towart the readings information
🎁
And than youl find planetary systems where there suns still needs to be born🌹
The end of the fallacies at the beginning god created light🤣🤣🤣😍
Our it means the light of understanding the behavieures of existance itself as the behavieures of existance itself where and when ever is the creation
As experiencing light is a interstallar senaspic padway dibiation translated in to experiencing light
Our own cosmetic lobido desides the light we experience (the space inbetween within and around oll and at the same time is oll🖤
Like in ansesterial jogy the used for the same conseptual dimentional understanding the word braman😍🌹😍

I have a question about light. It has its origin. Is there light has ended that can never be seen?
Captured rogue planet?
Due to the possibility of planetary migration, the upper limit of the age of the parent star can not be valid for all cases. Any idea how the age of an exoplanet determined? Has there been any observation on the direction of rotation of the exoplanets? Is this similar to what we see in our solar system? Why or why not?
How do they know the planet is young? How do they know it wasn't drifting through interstellar space and was captured in the gravitational field.
Wow it’s almost as if physicists are full of shit and have no idea what they’re talking about 😂
Keep it Tidy! Planet style.
Seems to me that this may have been an interstellar capture to begin with and now is growing again. Probably was a rocky planet to start but after “feeding” for a few million years it’s gotten much larger.
They are called theories for a reason.😂
A new gassy planet. Probably loaded with Sour Kraut & Beans.
That's a lot of beautiful artistic interpretations of what really only is what shows on 5:03 .There's an awfull lot of artistic fantasy involved in that. So a 'mature' planet signal is spinning around an 'infant' star signal, but even that is part assumption. A story based on hot air, about a story based on hot air, in a video that's still fun to watch. That's impressive.
Thx for not using the strange thumbnail pics anymore. 🤗
Another interesting one, thanks.
And is your graphics editing getting a little more…flashy? More sophisticated? I thought this one was really engaging.
The quickest way to form an object is by a stellar-mass gravitational instability (GI), and shifting the center of freefall away from a growing prestellar/protostellar core while the core still has a diminutive planetary mass would arrest the growth of the core at a planetary mass, resulting in its inertial flip-flop into a planetary satellite orbit around its new, much-more-massive offset center of freefall, forming a planetary and a stellar mass with a single stellar-mass gravitational instability.
Dust and ice grains freefall faster than gas, since gas experiences partial pressure support, such that prestellar cores may form mini-Neptune-mass rocky/icy centers even before the gas in a prestellar core becomes opaque to infrared radiation (where the opacity forms a first hydrostatic core).
The magnetic field lines in nebulae become concentrated in a Jeans instability, forming an hourglass-shaped structure with a rotating 'pseudodisk' at the center constriction. Magnetic braking in pseudodisks shifts angular momentum outward, creating a magnetically-truncated rotationally-supported (Keplerian) accretion disk interior to the pseudodisk, where the accretion disk in turn surrounds the growing prestellar/protostellar core. The angular momentum in the infalling dust and gas twists the magnetic field lines in the pseudodisk, which may result in a magnetic reconnection. And if the gas and dust liberated from a magnetic reconnection is much greater than the combined mass of the prestellar/protostellar core + the mass of the truncated accretion disk, then the center of freefall will shift to the liberated knot of gas, ending accretion onto the planetary-mass prestellar/protostellar core, resulting in its inertial flip-flop into a satellite orbit around the new center of mass which becomes the star.
Thus, gaseous planets formed by this flip-flop mechanism are older than their stellar hosts, and therefore should be apparent in even the very youngest protoplanetary disks. The flip-flop mechanism forms gaseous planets in the mass range from mini-Neptunes to super-Jupiters, and maybe low-mass brown dwarfs.
(Super-Earths presumably form otherwise by a hybrid mechanism, by hierarchical accretion of ~ 100 km objects formed by streaming instability, hence hybrid. And stellar systems with multiple super-Earths form sequentially from the inside out.)
I get gas planets forming like they say but I don't think they have a good model for rocky planets yet. Seems like they'd just constantly smash each other to smitherines….All they ever find are gas planets in the ecreasion discs.
