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.
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!
Red Giants are also very tenuous and combine that with their large volumes it's much easier to strip them of their outer shell.

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!
Wow what a facinating system!
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."
I wonder if the number and motion of stars near black holes could have much effect on the final parsec problem
Very interesting. Thanks for sharing Anton. 🌌✨
Thanks again Anton!
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.

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.

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.

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?
Thanks Anton.
Hello wonderful Anton! This is person
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 🙏
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 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.
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.
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'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?
Nice video.
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
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.

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
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
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.

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.
"3 body problem? Try million body problem."
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?
Every time astronomers see something that shouldn't exist according to theory......COLLISION !!!

What was happening to the star pulsing in left corner looked like a nova
they aren't weird, they're just "built different" (as the kids say)
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?
What is the actual timescale of the animation, weeks/second?
Welcome to the stellar mosh pit that is our galaxy's core.
You didn't mention that there are tens of thousands of stellar blackholes in that region around SgrA* too!
The central region of the galaxy is basically a globular cluster dialed up to the extreme.
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?
It does make sense that a red giant in such a crowded active area would get stripped pretty darn quickly.
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.
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?
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?
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?
@stargazer5784
Ай бұрын
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.
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?
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
One million stars in only four light years? Makes the three body problem look simple.
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
"In a nutshell, a few of theae have been discovered..." Wow they must be tiny!!
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.

Please do not confuse 4 LJ distance with "volume"!
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.
Hi Antoni. where did yesterday’s asteroid go? Did it hit the moon?
Im interested in S2. I can only find scant info on it
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.
Even from our point of view, how much does the Warp of spacetime effect something near the black hole as well?
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….
The Symbols in Shalidor’s insights might have to with the way light interacts with black Whole Gravitational masses 🤔
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.
I noticed EXACTLY the same thing!!!! When I flushed the toilet.
Stars near the black hole are young because time passes by very slowly.
