I want to see a simulation of the “night” sky from a planet where there are a million stars within 3 light years.
Space engine finna overheat at this point.💀
I like this idea
I don't think planets would even form in that environment but I also want to see that.
@@Pillarofcreation1screw it, I wanna see what floating in space surrounded by that many stars so close would look like
@@Auroral_Anomalynah it’s really good at handling all that
Having followed you for years, I am so grateful that you are still "Anton".
That you still find it worthwhile to share with all of us, cite references that only a small percentage actually read(don't stop!), and seem to still enjoy what you do.
Thank you, you beautiful human 💫✌️🤟🤘🤙
It's that big cheesy smile at the end, how relatable is that 🤣
Few
Glad he has evolved through the sandbox shenanigans into him creating his passion videos. I liked those stellar disasters but only for so short a time.
07:30
Additionally, Red Giants are extremely puffy on the outside. In an environment where stars are closely packed, they probably will be stropped of these outer layers more often than here.
Red Giants are also very tenuous and combine that with their large volumes it's much easier to strip them of their outer shell.
If you strip a red giant out of its shell, you get a blue subdwarf.
I want to see a direct-line collision of 2 stars at relativistic speed instead of the usual long slow death dance.
THAT would be something to see!!! Stay Wonderful, Anton!
"They go between a cloud and a star depending on where they are in the orbit."
I'm laughing due to how amazing that is. This is great.
Oh yeah so funny that i'm crying.
..."it seems to form these unusual POOFY objects" Finally a description I can understand.
I need a smart dumb guy to translate anton to me
Those are Lamingtons :P
@@thhseeking Oh I always wondered how Lamingtons are formed.
G objects are stars that, after being stretched by gravitational forces acting on them, are in effect sloshing around as the mass extruded from the core is rebounding back toward the core trying to go back toward equilibrium.
A particularly puffy G object will be one that has had a massive spin imparted upon the core by a pass by A* at some point.
I wonder if the number and motion of stars near black holes could have much effect on the final parsec problem
Oh wow! I read this paper before Anton (or at least his video) for the first time! I was so stoked reading and thinking about this paper as a friend and I had just been discussing the galactic habitity zone and through times, talking about some of these intense dynamics at the galactic core. Everything about S62 is crazy. The lead researcher sounds like an amazing person to geek out over coffee with.
Very excited for future research in this field and area!
I know this isnt related to this video but I think this would make a cool video. There's an article you can find by searching the following quote in google: "In two recent papers, an international team of scientists describes the first known nitrogen-fixing organelle within a eukaryotic cell. The organelle is the fourth example in history of primary endosymbiosis-the process by which a prokaryotic cell is engulfed by a eukaryotic cell and evolves beyond symbiosis into an organelle."
This was a really great one! Super interesting!
always a treat Anton! Thank you and algorithm gods appeased!
These algorithm mentioning comments are old and boring. Why don’t you ask Anton to be your boyfriend instead? ❤🍆😲
over a hundred million km per hour!!! wow, that is the speed of the star traveling 10% the speed of light. Amazing. Thanks, Anton Gr8! Peace ☮💜Love
Light travels at 300,455 kilometers per second. 10% × 300,455 = 30,045 kilometers per second. 30,045 kps × 3,600 seconds in an hour = 108,162,000 kilometers per hour or 67,060,440 miles per hour.
@@douglaswilkinson5700 thank you so much, I had mistyped and forgot a word.. haha, I'd also done it in my head in mph and got confused w/km.. I corrected my statement thanks. Gr8! Peace ☮💜Love
@@BrianFedirko You are welcome.
@@douglaswilkinson5700So it travels roughly the Venus Sun distance in about an hour?
Venus and the sun’s distance is about 108 million kilometers.
@@djchristian82Yes. Venus is 108M km or 67M miles from our Sun. (BTW One very important reason that Venus is so hot is that it receives almost twice the solar radiation as Earth: 67M÷93M=0.72. Venus is 0.72AU from the Sun. Per the inverse square law: 1÷(0.72²) = 1.93 or 93% more than Earth.)
Wonderful as always Anton. Thank you. 🤘😁
Thank you Anton for making this happen !
This was exactly what I said when you first talked about g objects many moons ago.
I love the picture of Sagittarius A. Amazing.
Anton, my wonderful friend....what do stars smell like? What would it smell like near OUR black hole? I'm considering the stars that go zooming by at such crazy speeds. Thank you for being WONDERFUL!!! Your fan from Virginia, USA!🤸🏼♂️🤸🏼♀️🤸🏼
Wow what a facinating system!
Very interesting. Thanks for sharing Anton. 🌌✨
Sag A* is a BEAST... can't even comprehend that monster flinging suns around like swatting at flies
A star with such high mass moving at 10% of the speed of light is crazy.....
Lots of unfathomable "outside forces" there, with the black hole and close passes by similar sized objects.
Thanks again Anton!
Dead superclusters and elliptical galaxies can for younger-looking stars via such mergers as well. I remember a study showing a cluster that was so old it should not have any stars greater than .8 solar masses have some stars at 1.6 and 2.4 solar masses.
Wonderful work! Such an exciting and dynamic environment to study. Just imagine the turmoil!
For once, a carefully planned simulation with outcomes that can actually be checked with careful observations.
There are many carefully planned simulations, verified by observations, that you aren't aware of and haven't seen. Many new discoveries have been made in the past by creating a simulation or model first, and then searching the universe for objects that fit the bill. Same emissions, light spectrum, physical characteristics, etc. If none are found that match, the model or simulation is 'filed', so to speak.
thanks for the amazing video and discussion anton
looking forward to more updates
question 1: no supernovas in that region of space or smaller black holes?
question 2: what, if any, effects of time dilation on stars moving ~10% the speed of light?
As usual, very informative.
Fascinating analysis.
Beautiful, interesting video, thanks👍😊
That paper by Rose and MacLeod is imo the most interesting astrophysical one you've discussed in a long time, and as you said it passes the "inbuilt-cranium-simulator" test as well.
Thank you Anton for your tireless work 🙏
I'm guessing there is actually two (or more) black holes there swirling around each other which is why the stars have such different plains of orbit. Just a guess tho
Our galaxy has only one supermassive: Sgr A*
Not a bad guess actually, as there is said to be a smaller 100K stellar mass object, somewhere in the mix. Deduced through angular momentum calculations and potentially responsible for the mysterious pulses that were detected a few years back.
Tidal stripping however from the larger blackhole likely rendered it mostly devoid of its own accretion, making it almost completely invisible to scans, but the additional scrambling to the rotation patterns in that region still partially give it away.
Thnx Anton!
Has a star collision ever been directly observed with a telescope?
What is a star? How would they know?
Only with LIGO, Neutron stars
Yes. But not the kind of telescope you're thinking of...I think.
@@RH-wg2gr You see the Sun? That's a star. They would know by looking at the star to see if it's hitting another star. Welcome to Earth, by the way.
@@filonin2 so pointing at the sun and saying that’s a star makes it true? Where is your scientific evidence. Oh, that’s right you don’t have any.
This study is awesome!
Hello wonderful Anton! This is person
Great video thxU Anton
I like it, it makes sense and it comports closely reality, the simplest explanations tend to be the correct ones!
Fascinating!
Finest quality production as usual. Thank you very much
"The current magma energy project is assessing the engineering feasibility of extracting thermal energy directly from crustal magma bodies. The estimated size of the U.S. resource (50,000 to 500,000 quads) suggests a considerable potential impact on future power generation. In a previous seven-year study, we concluded that there are no insurmountable barriers that would invalidate the magma energy concept."
Nasa/Sandia Labs, 1982.
Thanks Anton.
anton i love youR CONTENT
G objects similar to shoemaker Levy in degradation before impact with Jupiter. I'd expect the g objects to slowly increase in number imho...expecting quasar environments to be similar in final parsec
So, old stars collide and turn into young stars when they get going really fast.
If the same turns out to work for people, I'm going to get about fifty old guys. We will careen madly around my back yard until we turn onto young guys, or collapse from trying!
Thanks for the idea, Anton!
The kinematics in that area are nuts. So much mass moving so fast. Would be super interesting if we could one day watch a star get ejected or have head on collision. That's sure to create some fireworks.
I also want to know what that star in the top left of the time-lapse is doing, pulsing forcefields like that
So if we.r say you had 100 stars in the last couple light years, you then have a hundred barycenters moving at similar speeds to the stars with changing locations.
I'm curious if a Civilization we're close enough to launch a probe to a Star like Sag 2 which is screamin around Sag A at 10% Speed of light could a gravity assist be utilized from that insane speed? Would that stellar neighborhood be to busy to calculate a trajectory back out in a meaningful time frame?
Could you comment on any implications of tidal forces of the black hole upon stellar hydrodynamics combined with nucleosynthesis, including alterations in convection of heavier elements to more superficial regions within different star types? Also, what may be some impact of tidal forces upon internal energy levels and on fusion processes of heavier elements, which may also affected by loss of mass to, say, the accretion disk with simultaneous interaction of highly dynamic magnetic fields approaching perihelion? Finally, are you aware of any hypotheses considering the fabric of space-time in such gravitationally intense and variable environments at varying distances from the black hole but in conjunction with orbital patterns of different star types and astrophysical fluid dynamics of, say, directional movement of astrophysical jets?
Did I understand that right, that they basically went the Ockham's Razor route?
"You know, we know that there are a ton of starts really close to each other in a very small region of space. What if, nad hear me out, what if they just crash into each other a lot?"
I imagine anything living wouldn't wanna go anywhere near all that.
The radiation must be so intense you would vaporize in a zepto second.
Nice video.
Always wondered about stellar collisions and chaos around sag A*. I want to see a simulation of future events like we can run of our own solar system.
* Srg A*
I've been wondering bout this for a while since I saw the early data. I heard once that there's electron orbital interactions that happen between stars and there gravity. idk if it's refudiated, just a random nugget I picked up that I wish I knew someone in academia who could find out things like that and now I do. Science writers tippy tap in circles to wow and awe people with whatever works, they're way better than discovery channel. But your the best. I love telling people what's happening with stuff and things but they don't seem to be interested, it's like feeding my knowledge and body doubling something that I compulsively enjoy doing some times, feeding cogent information/theory , being a teacher's pet I suppose
I've always wanted to see this and have always believed it's how matter would react around a black hole if there was enough.
Maybe they are only one or two stars but they’re getting reflected multiple times from different directions. Like, as if space is curved it takes longer time for the upper right reflection to reach us. Or something.
Ok, but this requires magic giant space mirrors, which no one has seen nor proposed before your post. Bends in space time do not cause reflections of light but they do cause light to curve so if there was some massive object between us and the black hole it could cause multiple images to show up at DIFFERENT times, not the same time.
@@filonin2 If it looks like 7 stars but only is one it would be at different times. You'd see it from different perspectives, from different times, at the same time.
At 1:45 Can someone tell me if that large bright object that comes in to the screen at the very last second is a normal star? It looks like it has way more objects orbiting it and way faster than Sag A star does in this image.
There may be no red giants because they are so unstable and diffuse that with all the commotion going on around them the outer layers of the star are easily stripped away leaving a remnant something like a brown dwarf.
the stars are telling you something.. if your machines could only read empathic energies, youd know everything.
.. "thr stones cry out"
I wonder if they appear fast because of the effects of being so close to the black hole? But, if you were an observer on a planet around one of those stars, I wonder how fast things appear then in the local group, and if the stars further away in the galaxy appear very slow moving?
4:39 this is so crazy to me man. mind blowing infromations
Infromation
@@As4vo ahahah
Just...imagining the size of that nutshell 🤯
Do all the stars orrbit the bkack hole in the same direction or do some orbit in a counter direction, and what would happen if two stars orbiting in contrary directions collided at a combined speed of 20% of the speed of light? Could any super-bright gamma ray bursts from the early universe be due to such collisions?
With stellar collisions and supernovae happening regularly in this region, can we assume regular-size black holes are also in the mix of objects orbiting the central supermassive black hole?
Do the simulations account for planetary objects? If so, and with so many stars in such a confined space, would planets constantly get slung around from one star to another?
I have heard that there are a large number of stellar mass BHs in the galactic core.
Even from our point of view, how much does the Warp of spacetime effect something near the black hole as well?
This video liked👍
Every time astronomers see something that shouldn't exist according to theory......COLLISION !!!
In the vastness of space🙄
What is the actual timescale of the animation, weeks/second?
You didn't mention that there are tens of thousands of stellar blackholes in that region around SgrA* too!
What was happening to the star pulsing in left corner looked like a nova
Im dead. First he said they answered all of it. Now he just said kind of" so which one is it? I love these time stamps 😊 3:30
This is where he said they solved it all at once. 3:15
Welcome to the stellar mosh pit that is our galaxy's core.
Sagittarius A* Region reminds me of balls on a Pool (Billiards) table, or Marbles when we Shoot them when playing a game of Marbles as kids.
Also like the Autobahn in Germany, while Stationed there early 80's Average Accident was 16 vehicles, Highest 40+
10% of the speed of light must be measured from near the black hole (measured with red or blue shift here), but since the black hole gravity slow time (or the other way around) relative to us, what would be the speed from our point of view if we don’t use red or blue shift?
The Symbols in Shalidor’s insights might have to with the way light interacts with black Whole Gravitational masses 🤔
Heres my expectation of some of the physics at play:..... "These collisions pump kinetic energy into the cluster, causing the cluster to expand or to halt contraction, this is called binary-burning. The interactions between binaries and star acts as a heating source which increases the total pressure of the cluster counteracting gravitational collapse". ....source: NASA ....globular clusters
That first graphic: nice clockwise logarithmic spiral...
haha that smile at the end
Couldnt this explain how black holes got so large, collisions of stars that were too close, until they reach a large enough object to collapse into stellar mass black holes themselves. Eventually combining with the central.
Regardless this is neat, could we perhaps see what the inner core of a star realllly looks like? Because we can crunch the numbers but like Earths core we dont truly know.
Im interested in S2. I can only find scant info on it
would a million stars with ludicrous speeds in a span of a few lightyears share composition due to contamination or are they still far enough apart to remain original?
Maybe the 2 things you need to know about that area are 1) Stars that get too close to the Black Hole are likely damaged 2) Solar systems in the area have a high probability of being destroyed due to random collision.
If any stellar systems formed it would be the gravitational interactions that would rip the systems apart.
"3 body problem?
Try million body problem."
The central region of the galaxy is basically a globular cluster dialed up to the extreme.
Hmmm. Wonder what kind of elemental composition that region of space would have? Surely slamming together stars at 5% the speed of light would cause elements to fuse differently than a more traditional supernova….
I have what may be a silly question, but I'm not a scientist. How can stars merge? I mean- it sounds like a gentle event rather than a violent one. As I understand it, stars that are close enough and whose orbits decay orbit closer and faster until they collide. The animation at 4:46 represents a touching binary...how is that even possible that the stars' upper layers are touching co-mingling plasma but they remain otherwise intact? Is it that the cores need to collide rather than the upper layers? And if so, how do some stars merge this way rather than be destroyed by the collision?
Also, does anyone know the distances involved with the stars around Sagittarius A* ? I know the center 25K +/- light years away but I'm having trouble trying to visualize the distances between the stars from each other as wdll as the black hole. The speeds are amazing...it's one of the many things I wish we had the technology to clearly see.
2:19 actually, things goes slower from our perspective due to the star's relativistic velocity 😁
The kinematic time dilation of stars traveling at 10% light-speed is only 0.5%. (For comparison the time dilation at 90% light-speed is 7 i.e. for every day on a spacecraft going 90%c then 7 days would pass in Earth.)
@@douglaswilkinson5700 exactly. On large time frames, 0.5% means a lot of dilation in terms of human scales
It's the 3 body problem...
Times 1000
Makes sense to me.
6:41 Actual Stars get Surgery too😂
Maybe our sun and second sun collided. The only way I see blue girbts forming by Star collision. The would have started fusion and pushing away more gas other wise
"blue girbts", huh? You're not supposed to drink the bong water.
they aren't weird, they're just "built different" (as the kids say)
So if collisions are so common that there are many 8+ solar mass stars that live 1 million years and then go supernova......where are all the resulting nebulae?
Nebulae can't remain 'cohesive' or stay bound to the star in such an environment as the star's velocity is far too high for the very tenuous nebula to 'keep up' Also, a nebula's appearance is governed by several factors, two of which are expansion velocity and the gravitational force pulling back on the expanding cloud. Sag A* is the 800 lb. gorilla in the room.
Hi Antoni. where did yesterday’s asteroid go? Did it hit the moon?
"In a nutshell, a few of theae have been discovered..."
Wow they must be tiny!!
Nope, its the gravity from dark matter in space surrounding the black hole, counter acting the gravity from the G-star keeping it together. Thats why as it get close to black hole, its the concentrated dark matter in space pulling out on the star which , causes it to start to fall apart, as it moves futher away from black hole, and the amount of dark matter in space is reduced , it comes back together, that why tales follow behind not toward black hole, its the gravity from dark matter in space pulling them apart.
When stars go around the black hole and we have photos of it that have been turned into an animation, why then do we not see then get distorted when getting close or go behind the black hole as we see in simulations, why can't we observe any gravitational lensing from this black hole?
It does make sense that a red giant in such a crowded active area would get stripped pretty darn quickly.
Could planets be "traded" or "captured" by star systems interactions? If so the chance must be absurdly low.
Um... 100's of massive stars, all primed to supernova in a short time... Does anyone know where we can find Beowolf Schaeffer for a quick trip to the centre? Suddenly Niven's 'Core Explosion' seems a lot more possible!
