Same here. Astronomy and astrophysics is one of my passions, but I'm not smart enough to understand the formulae and difficult details. Luckily there are channels like this and pbs spacetime, to at least keep informed on the subjects.
I would think that the most likely outcome would be that the black hole would capture one star while it's binary twin was ejected. This happens frequently and it's likely that SgrA* would be no exception
Antonio ,thank you for your easy-to-understand and to-the-point posts that contain great material w/out the lengthy fluff contained in the posts of certain other presenters. I love watching your videos because I learn better when I don't need to wade through bits of knowledge that come as a stampede. Thank you for saying what needs to be said, without the: "Look at how smart I am!" effect. Your videos have helped me to be able to understand what many other videos try to say in volumnous words, but have too much crammed into them. I love space (and nearly everything about it.) You make my journey through more enjoyable.
Ever since I was a kid, "fusion energy" (cold or not) has always been described as "Just twenty years away!!!" Tip: Don't hold your breath until that happens.
Reminds me of my favorite thing to do in US2, shoot stars through the Solar System at various velocities and angles, just something that became interesting after hearing about these 500+ kps stars in our actual Galaxy. Generally the faster it's going, the less alterations to Solar System object orbits, relative to the star's mass
If you are talking about hypervelocity stars mentioned here I doubt it. I suspect a supernova kicking the star out would strip planets from them as well.

This would make a great graphic image on a new shirt in your web store, yep, a young binary system orbiting close to SgrA*. I'll definitely order a few Anton.
That is called a black hole merger. What LIGO was built for! (The "disruption" comes out in the form of a few Solar Masses worth of gravitational wave energy!)
220km/s... but a galactic year is about 250m years. Galactically speaking, the solar system isn't old enough to drink yet. The size of the universe is quite mind boggling.
1:06 Is the galactic escape velocity everywhere the same or is f.i. smaller at the edge of the galaxy compared to inner region? What are 520 to 580 km/s referring to?
It varies with distance from the center of the gravitational well. I'd expect it to also be a function of the direction of travel, and the amount of mass in front of you. (None of it, hopefully, being _directly_ in front.)
At 7:43 there’s a graphic showing North at the top and East on the left. I know things get weird near a black hole but East and West actually change direction?
I imagine the perception of relativistic time for someone living in a star system orbiting the central black hole. If one left a nearby star and lived ther for a few years and then went back there, would decades have passed? What if the orbits changed and it then it became the other way around..
I wonder what orbiting near a central black hole might do to the internals of a star? Does orbiting a black hole "stir the star's guts" mixing and remixing the internal layers of the star, and does that change the way it burns and its appearance?
Why you asking us? You made him/ it up. So, whatever you want? It’s your imagination. You tell us. Go wild! I like to imagine god as sphere of runny excrement, the result of an “accident” in zero-g.

It's always sad when binaries can't get along. Sometimes one of the pair gets kicked out of the house to be melded into the bright lights or fly off to Heaven knows where. Should we set up Go Fund Me accounts for the rejected one? Lost, alone, running from its past must be a terrible struggle.
You say stars around the blackhole look too young. What about time dilation, like Cooper in interstellar, he also looks too young at the end of the movie.
Could it be possible that new stars are forming from the stars that turn into a cloud like object when approaching Sagittarius A*. Or something along those lines Where the stars look young because they get ripped apart and form over and over again. Effectively making them new or disrupting the "length" of it life
might it be possible that the observed star(s) originate and are ejected from the black hole itself? (I've always found it rather curious that there are supermassive black holes at the center of every/most galaxies.)
Imagine a civilization spots a red/brown dwarf heading out of its parent galaxy. They could encase it in a Dyson swarm and go live in the country for possibly a trillion years and not have to worry about other civilizations coming along.
❤❤star s29 was close, huh? The thing is, they said it went 8% the speed of light as a result of gravitational slingshot at closest to Sag A, but they forgot to mention time is also gravitationally lenses, and it's possible it went MUCH MUCH faster. Would be great to know that math problem.. it is very possible that your 2.7 million year old star has been a time traveller by result of close proximity!❤❤❤
Maybe this is ignoring Occam's Razor...IF the star systems are hypervelocity, and will eventually escape the galaxy: WHY ASSUME they didn't originate from outside the galaxy (in intergalactic medium)? SURE the interstellar space is mostly empty (seems to be) in our galaxy, so the rogue star could get pulled into the galaxy, NOT INTERACT w/ any stars and escape out the other side w/ or w/o making an 'approach of the SMBH. BUT the rogue star could also transit through our galaxy, interact gravitationally with a few dozen stars along its path (so zig-zag along its 'galactic transit' path), then escape back outside the galaxy. ALL this makes more sense, and would seem to be way more probable.
Because if they were from outside, there'd generally be a similar number of star velocity vectors going inwards towards the core and outwards. But what we see is all of the hypervelocity stars coming out of the nucleus. It's statistically very unlikely we just randomly have a case where they are all coming out of the nucleus in your idea that the hyper speed stars are just everywhere
Numbers aren't on your side. There isn't much matter in "intergalactic medium" by both definition and observation. While there are small gas clouds, few stars would be able to form out there. A tiny number. An even tinier percentage of that tiny number would be be accelerated to the high speeds seen-by the exact same mechanisms suggested here. So there may be a few! But far too many hypervelocity rogue stars have already been seen for that to be the usual case. Occam frowns at your idea being "the simplest."
Unary = having 1, Binary = having 2, Trinary = having 3, Quaternary = having 4. Nothing to do with binary numbers or binary logic. Just another way of counting something in English.
@@andrewleccese8974 Great suggestion! One more question though. In Arithmetic, 0 is the absence of something. If 0 is the absence of something. Then what would that something be?
Getting close to Sag A* would be like a huge centrifuge. I could imagine the heavier elements being stripped out of stars. Would this just collapse the star or allow Hydrogen fusion to re-start therefore rejuvenating the stars?

Cold fusion is like the ultimate bad first date-it promises endless energy but never shows up, leaving scientists ghosted for decades.

On the other hand, normal fusion is actually close
But it's nowhere near as useful
Thank you Anton.

Hello wonderful G-Object!
It is also possible that old stars when they near Sgr A* pick up material from the accretion disc and that makes them look way younger.
Fascinating!
Beyond current understanding.
Fair Enough.

They may have solved the mystery but we have an Anton.

We should call stars that are ejected by SgrA* from the galaxy as "bounced" stars.

How much of a factor would time dilation play that close to the central black hole?
I'm curious about the distance between these stars and sag A. How long each orbit takes. I'd like to know these answers.
That sounds like Hawking Radiation writ large, the binary systems parting ways at the center of the galaxy.

I am curious what 1000 kilometers per second would look like if something passed by within sight of you at that speed.
You say stars around the blackhole look too young. What about time dilation, like Cooper in interstellar, he also looks too young at the end of the movie.
Plot twist, Sag A* is a white hole and we are witnessing the birth of spacetime.
has any high-speed stars that came from outside our galaxy or from intergalactic space?
Could it be possible that new stars are forming from the stars that turn into a cloud like object when approaching Sagittarius A*. Or something along those lines
Where the stars look young because they get ripped apart and form over and over again. Effectively making them new or disrupting the "length" of it life

Those stars like Romeo and Juliet, are not both likely to survive the coming disruption event.

There is no hope if a star gets ejected and heads towards earth!!
