Incredible Discovery About The 1000 Light Year Local Bubble

[@dbirch001]

We live in a great time. Not too late that we can still see far enough into the past, and early enough that enough interesting stuff is happening to observe and form hypothesis.

This bubble is yet another factor of our Fermi paradox. The right time and the right place!

[@nitrostudy9049]

I guess it is too simplistic to suggest that - if the bubble has reduced hydrogen, it might imply that that wavefront has a zone of increased hydrogen density. The increased hydrogen density, and pressure wave, would then facilitate new star formation where it reaches other bubble fronts (or pockets of more dense hydrogen)?

[@jmgilsinger]

...by agitation of the materials present. That's what I was thinking. But I was also thinking "nature abhors a vacuum", and wondering why the bubble of low density continues to expand as far as it has, for as long as it has, with no "holes" in the shockwave front where matter is being pulled into the region. Or perhaps they (incoming streams of higher density) are there, and just not identified yet.

[@jmgilsinger]

Also, a volume of interstellar gas has gravity. It doesn't collapse to that gravity because of heat pressure. If the heat pressure reduces enough by shedding radiation, gravity collapses the gas. So, that agitation might release more radiation, and it may also be adding more gravity by rolling a wave of material through an existing gas cloud. This would make it more likely to collapse the gas cloud into a star.

[@ichigo_nyanko]

@@jmgilsinger I thought the heat of interstellar hydrogen was super low? where is the heat pressure coming from?

[@stefanr8232]

@@jmgilsinger In airburst nuclear tests on Earth the shockwave hits the ground and bounces. The reflected wave catches up to the front shock wave because it travels inside a moving gas. In some photos you see something like a skirt around the expanding fireball sphere. In space you see the Torus molecular clouds on one side and Corona Australis molecular cloud with Pipe nebula. These are obvious dents/holes in the bubble. Barnard 68 is a little pocket left behind and is collapsing on itself. The vertical height of the bubble/void is close to the scale height of the Milky way's thin disk.

Oddest comment.

[@MaryAnnNytowl]

These are some freaking awesome maps, and this is a fascinating discovery! As for them interacting, they'd surely have to, wouldn't they? They're not made of neutrinos, after all! I'd hypothesize they would interact much like any other waves would, and what visible results would be found from the interaction would be determined by what the waves are doing as they meet. Are they one on an "upswing" and one on its "downswing" as they meet, or each on their up and/or each on their down. I hope that makes sense to others - it sounds good in my head, LOL, but I don't think I'm explaining it very well. 😄😄😄 I'm thinking of constructive interference vs destructive interference where the waves meet. Anyway, yet another great video, Anton - we aren't ever disappointed with them! Well, at least _I'm_ not... I'm sure there's party poopers out there that are, but to heck with them, right? 😄😁 Stay wonderful, man!

[@jacobkeller29]

I think the principles that apply to the theory that all these little bubbles from stars exploding merged to create the large bubble we are in would have to apply to what happens when larger bubbles collide. But along the lines of what you said, how waves can merge to form larger waves, would probably have to occur so that enough matter can accumulate on the outside of the bubble to get to the point where gravity can take over and something can form. If the bubbles didn’t merge and grow, the theory doesn’t really work out in my mind, because they would dissipate and cancel each other out. Gotta go blow some bubbles

[@MaryAnnNytowl]

@@jacobkeller29 yes, that's my thought, that the ripples would have to shove the dust together close enough to start gravitational interaction with each other, or there wouldn't be this obvious formation of new stars along the leading edges. (Edited my stupid typo)

[@johnpayne7873]

You always get me thinking, Anton Specifically, the effect of “lensing” by a surface of different dielectric susceptibility. I think that the density of a nonreactive gas is linearly proportional to the electrical susceptibility. Since the sun is in a low optical density “local bubble”, light would diffract divergently from a “large” source (like a spiral arm or a large nebula) making resolving objects more difficult. As a side note, “point” sources like stars or very distant objects would be minimally distorted owing to the light rays would be perpendicular to the Local Bubble surface. Moreover, the effects of multiple local bubbles within the Milky Way would compound its “milky-ness”. Thoughts?

My thoughts: you're right, we should analyze every space data with light distortion taking place, but we mostly ignore it even if dust is everywhere in different densities. Imagine i.e. the red shift distances calculations 🤦‍♂️

[@NorseGraphic]

Wouldn't the gravitational effects by suns and black holes be a lot stronger than the lensing-effect? (I envision your take in the original post as the same effect as when light goes from air into water)

Well done, one must remember that solar bodies are energetically windy, and create some pressure that would help exclude dust from the outside, although of course not excluding such completely. Especially given they also have a large effect on local space curvatures, {iow, gravity}

@@Barbreck1 That would only be true if the expansion was, a. faster than any possible movement by the stuff within, and b. if the expansion was directional, if it was just the solar winds driving it we would have precise calculations that match predictions, we don't.

[@Barbreck1]

@@brianstevens3858 Why faster, why directional? Stellar winds emanate outwards in all directions simultaneously from every star. They interact with opposing forces from other stars. Basic Newtonian mechanics dictates that those objects will exert an equal and opposing force upon one another, driving them apart. Add a dozen other local stars to the mix and you have a rather complex picture of forces interacting with one another. Collectively (as a galaxy) their forces upon one another are somewhat countered by the effects of gravity, such that they collectively orbit a common center of mass and fall into a pattern which is complimentary to the velocity and mean mass of the collective. However, although the stars within are trapped in this gravitational (and mutually-repellant) waltz, the galaxies themselves are not. They are, in effect,“weightless” and yet, from them is outwardly emanating the vast collective wind of the stars burning within. This galaxial wind then interacts with similar oppositionary forces, driving the galaxies apart and sending them into a vast three-dimensional game of billiards. Since their exists a vast array of galaxy masses, the forces are unevenly and chaotically distributed, resulting in an equally chaotic movement of the galaxies, this is evident in the fact that the galaxies are moving in random directions and not toward or away from a common point. Nonetheless, since every galaxy we can detect is doing the same thing, there results the wild and chaotic cosmos that is evident. No need for a prime mover or trigger force, this is nature doing what nature does.

Fascinating! I imagine the model as grains of magnetic sand scattered across a cement floor. None of the grains individually have sufficient attractive force to draw others in its area towards it. Then, a push broom (a supernova) comes along and sweeps a bunch of the sand into a small area, where they all start bunching up. Together, their magnetic attraction is enough to start pulling other grains of sand into the main mass, making it ever larger and more attractive!

Great one Anton! Moving bubble surfaces "sweep-up" dust as they expand. In this way they act as a means of mass entrainment. Mass then concentrated locally on the bubble surface by gravitational forces. Two shock-wave bubbles interacting might merge or even break up into smaller ones. There must also be a slow dissipation process. It might be worthwhile to set-up a population balance description (I have multivariate solvers) considering bubble size and surface mass concentration.

[@davidh.4944]

There are indeed several other bubbles known to be adjacent to our own. The boundary with the neighboring Loop I bubble (home to the star Antares) even has an opening (actually multiple) called the Lupus Tunnel connecting the two voids. It is also thought that the Local Interstellar Cloud formed from the interaction between the two loops. You can actually see it in the graphic a @2:15 in the video. Although not clearly labeled, the larger lobe around Antares is obviously loop I. I'm guessing the third lobe is likely Loop II, but I haven't been able to find any confirmation of that. I believe the large clusters of star formation in the graphic @4:30 are also on the Loop I boundary.

[@spindoctor6385]

Just from the graphic it seems to me that the conclusion could be backwards. With all the star forming regions on the "surface" of the bubble it looks as if the star forming regions stop the bubble from expanding rather than the bubble causing the right conditions for the stars to form. This would also explain the shape not being spherical, otherwise you would need to explain why the expansion of the bubble is not consistent.

And your understanding of probabilities seems to have gone off the rails, too; and not exactly by accident, but rather under a familiar dark dynamic where conclusions come first. Your last argument is like dropping 100 quarters on the floor and then wandering aloud _"What were _*_the chances_*_ that _*_by coincidence_*_ they would all end up exactly the way they did? _*_0.0000...0001%?

To me it reminds almost of a cell. Its not at all functionally similiar but the pressure difference makes so many different things about galaxy formation make more intuitive sense for me. The pressure pushes everything away collecting all the matter along the edge that eventually coalesces back together into almost a ring just like planets, only stars are formed, and since nothing is ever perfect the matter will eventually clump and start another super nova starting the process over again. The missing piece i never considered was how everything got pushed away in such a manner to keep it all relatively clumped together, but to think about it like an ocean, but opposite because of the pressure makes so much sense to me. Love your videos, i have so many theories and ideas about the nature of reality and the shape of the universe and time itself, but being poor and working all the time i dont exactly have the time to go to uni, your videos always covering the newest discoveries and confirming ideas ive come to myself makes me feel like im just as smart as these scientists.

all it takes for gravitational coalescing of an otherwise static hydrogen+ cloud would be physical interaction with an expanding ionized shockwave. space doesn't provide many free electrons since it is an insulating vacuum. so the H+ gas cloud sits and waits in a static fog of mutual repulsion till something tips the balance. a solar wind filled with charged particles seems to me the most logical way to disrupt the peace. this process would be akin to molecular precipitation, the hydrogen finally having the field energy to convert to h2 and gain the mass needed to draw together. as the clumps grow, the molecular complexity grows. the electrical discharge within the cloud as the negativity is trapped would provide the spark for fusion, i expect, at least for a range of lighter elements. all of which are heavier than H+, and these would hasten the collapse. pure conjecture from my basement, of course. i love how you make me think, Anton :)

The Earth passes out of a dust cloud which, unbeknownst to everyone, was the cause of man’s inability to use 100% of the brain (unknown type of radiation in the cloud). Suddenly animals’ intelligence surges and they demonstrate behaviors previously thought to be impossible. The story is told from the perspective of a young man with limited mental faculties. He now sees and understands things like never before. The average person gains all types of abilities and Man leaves the earth for the stars en-masse. Those whose limitations make them the perfect stewards for the planet are left behind and monitored for their, and the planet’s well being. There’s a lot more detail in the story and unfortunately I can’t remember it’s name but this discovery is spot on with the main story plot.

we probably just figured this bubble dynamic and, as Anton mentioned, and if thats statistically very common then is it possible that the very interactions betwen various bubbles can be what is pushing together the material into itself creating higher density regions where stars can swallow and form? that could explain the unusual shape, like a interference wave on a pond but spherical and squished by other similar structures but maybe they can push and squish each other as well as pass right through or permeate, whilst colliding and creating complex matter

Thanks for another great video. I have a question though: Could it not be the other way around, and that the places where stars are being formed have a lot of mass and therefore suck the hydrogen out of nearby places? That way it's not pressure, but just gravity.

[@stefanr8232]

Gravity is obviously involved. A rock rolls down a hill. That happens "because of gravity". An observer looking at it might say "that rock is rolling down the hill because Simon Gross kicked it". Neither statement/model is wrong. The dust grains formed billions of years ago. Why are they just now accumulating with gas in Taurus and Corona Australis?

[@paavobergmann4920]

I think both. If everything was absolutely evenly distributed, nothing would move. Blow out a cavity and kick it´s content into the surrounding space, you form a wall of slightly denser material. There, gravity can take over, because the density is higher than in the surrounding volume, and stuff starts flowing along the gradient into the density --> star formation starts. Kind of like a condensating fog or rain droplet sucks water vapor from it´s surrounding as it grows.

[@kombatkarl44]

It would be cool to see the Voyger info plugged into these models specifically the info about the Heilopause region....and how these bubbles may have affected it....

0:55 @Anton Petrov This map has two problems 1. Why is Barnard´s star on the right (5.96 ly) visually further from Sol than Luyten´s star (12.2 ly) 2 on the left. Why is there no single designation system on your video? I tried and failed to Google names on this map. In Wikipedia Luyten is GCTP1755, BD +05°1668, GJ 273, G 089-019, LHS 33, LTT 12021, LFT 527, Vys 17, HIP 36208 or G 272-61A and B on this map. Not even the 272 is the same in Wikipedia 273. You don´t have to change astronomy, just name these stars in a single way for this picture. Edit the gruze org galaxy map photo.

thankyou wonderful , Auton

[@stephenbrickwood1602]

Wonderful work.

[@harrywhite7287]

Cool. Thanks Anton.

The fact that there are clouds in space is pretty cool

[@evasartorius9528]

Another great job.

[@dougselby7592]

This is very beautiful. I like topological ideas. I suppose that bubbles might form large strands, were their surfaces to meet?

[@jeromewalton5553]

So does that make our sun still near or traveling with the gas cloud edge that could have created it? Then that means “our” cloud is interacting as well, sounds plausible and could also play into the theory of the edges being star formation areas. Very cool. I suppose that makes the galaxy as a whole like a giant mixer and all of the little component pieces like ingredients.

Like a dropping oil in water. It makes many bubbles, doesn't mix, and maybe that's the environment our type of life needs to exist within a lighter density. Expanded by explosion, hold in place by heavier stars at the edges? and the sun being caught right in the middle. Precise as mixing fluids under a microscope but randomly as one lucky egg in the ovulation process.

[@mrbyzantine0528]

Perhaps it played a role in human evolution, perhaps its just a coincidence.

Maybe the stars on the edge of the bubble are forming BECAUSE the bubble is currently touching the neighbouring bubbles. It seems logical to me that pressure because of bubble collision is more likely to be the reason these stars form as opposed to just being on the edge

[@MichaelHarrisIreland]

You do a great job, so interesting. ....from Ireland.

[@robotaholic]

Dear wonderful scientist: I wish you'd take one video to list all of your favorite celestial mysteries or new things you've learned..it would be so interesting- thank you -John

[@ancient_history]

Really interesting, thank you for the highlight!

[@irtehpwn09]

Seems kinda intuitive, pressure wave pushes material into other material, which raises temperature and clumps matter more closely, that then warps the space-time around it, causing the clump to feel the effects of gravity more, pulling the material together, which increases pressure/heat and boom you have ignition.
