    wait wait wait . . . isn't our supermassive blackhole THE heart / anchor point of milky way ??? supermasive black holes DO control the structure of galaxies to some extent . and the 2 are connected in more that one way . . so doesn't that make supermassive black holes the central "cores" of galaxies in a way ???

    Correct me if I misunderstood what you said, but surfshark hacks databases to search for my passwords and other info right? Again correct me if I'm wrong, but isn't hacking considered a crime? Even if it's hacking criminal computers, it's still unauthorized access, if you kill a murderer, the fact that they are a murderer doesn't change the fact that you committed a crime, if you are going around hacking looking for info, you are just as bad as the criminals with the info to begin with

    Black holes are the result of a misapprehension by astronomers about the nature of gasses. mainly that they can NOT self compress under their own gravitation the math that claims that gases can self compress produces an infinite result from a finite set PERIOD! you can class this failure how ever you wish call it a violation of thermodynamics or a failure to adhere to proper unit rules the fact remains that you are producing something from nothing at some point in that model and it is BULLSHIT and you damn well know it.

    One of the most interesting things about studying black holes is finding out just how much we DON'T know about the universe. There are things in space that simply defy the laws of physics & reality as we understand it - LIKE dark matter & where black holes really come from. More alarming is the fact that rogue black holes exist, not tied to any 1 position, but roaming freely through space, grazing on stars, planets, whole galaxies, & anything else they come upon. And we're still not really sure how physics works, or even if it DOES, inside a black hole. Who knows what else is out there that we can't even conceive of?

    The main reason why physics breaks down is because singularities don’t make sense. They defy the Pauli Exclusion Principle which is a quantum mechanical theory, due to relativity. Singularities have no dimensions, just points of mass. Quantum physics hates this. Which is why relativity and quantum mechanics do not work together.

    Exceptional except for the errors I suppose. Simon states that the Sag A* has a radius of 22 million km and then states that Sag A* would extend to Mercury in our solar system…. Sun to earth is 1.5 million km so the distance to mercury is way less than that. Also nothing except research papers are a product of physics. Physics describes nature so things are a product of nature such as Sag A*. Also all black hole leak and the leaking stuff is Hawking Radiation and overtime they can leak away completely if no new matter is accreted. So given that what Simon is describing is jets of matter shot out the poles of the black hole because of magnetic fields and charged particles. Anyway he’s just listing facts and reading a script with absolutely no understanding of the topic. So that makes it a crap delivery.

I love it!

    At the risk of sounding super pedantic(sorry lol) the black hole isn't so much in the constellation as in the _direction of_ the Sagittarius constellation. Though one thing I find super cool is that our solar system is located in the Sagittarius arm of the Milky Way. I don't put any stock in zodiac signs, but I've always liked that I'm a Sagittarius so when I learned the name of our supermassive black hole and our solar system's location I was pretty stoked. Sagittarius is by far the coolest constellation. Also, most large galaxies do sometimes "hit" other, smaller galaxies and often even cannibalize them, taking in their stars and gas; the Milky Way is no exception. Some of these galactic remnants around our galaxy appear as sort of little smudges in the outskirts of the Milky Way. We've also got a few small satellite galaxies like the small and large Magellanic Clouds which are super fascinating in their own right.

    While I'm not 100% and could be very wrong, I think the JWST won't do great on this because of the sheer amount of light between us and the center. Its also more tuned for redshifted waves that no other telescope was able to see, meaning its better at super far stuff rather than visible light.

    1.) S-2 would not orbit "clouds of dark-matter" in any way similar to its observed behavior. 2.) When we are able to calculate initial collapse phenomena, we will also be then able to back-fill/map most of the history to find its long-lost intervened progress as CMB-projection. 3.) Watch for "amazing" & "never-guessed" (etc.) 'excessive' lensing 'fairly centered along gallactic-arm (expansion-) filaments.., which we actually orbit. 4.) 'Betcha' a quid...

    Using Gravitational Waves to study black holes has a limitation - size of hole to be studied is proportional to length of detector, so LIGO & GEO can only study black holes a few tens of the size of the sun. We will need massive solar system sized space based detectors to study the largest black holes. Great video on this by Dr. Becky

    Just wanted to point out a few things. When we are looking through space we are also looking back through time. The quasars that are seen are black holes that were active because their galaxies were still in their early days of formation, therefore the gas and dust in its proximity had yet to be corralled into the disk shaped spiral galaxies we see today. When a galaxy is forming most begin as just dense pockets of gas and dust but thanks to inertia and the conservation of energy most objects in space (... okay probably all objects in space) begin to rotate. In a galaxies infancy it’s elliptical and many spiral galaxies that collide also tend to form an elliptical galaxy as well (mainly due to the effects of those two galaxies and their gravitational stress they exert on one another). Elliptical galaxies are where there is small amounts of rotation but since they are generally primitive (again elliptical galaxies are very far away, the further we can see, the longer ago that structure existed) the galaxy we see very red light, hence why they look orange (and redshift). In a spiral galaxy that central black hole blasts those super heated x-ray beams and matter at its poles, further compressing the gas in the galaxy into a disk spaced spiral galaxy, starting a swath of new stars to be created, making the spiral look blue and bright because it’s creating very massive stars that have very short lives but emitting very bright blue light and of course many sun like stars but primarily red dwarfs (which is why spirals have so many colors compared to elliptical galaxies). Elliptical galaxies are often called "red and dead" because they lack that star forming pressure those polar jets centralized supermassive black holes create. No jets, no centrally compressed spiral, few new stars, few huge blue super giant stars (they live for a very short amount of time; millions of years instead of billions like our sun, and then of course the trillions of years red-dwarfs will fuse for), more lower mass red-dwarf stars that will exist far longer than their larger siblings... hence why elliptical galaxies are aptly called red-and-dead.

I've watched just about all the space related content there is, especially How the Universe Works. I've never come across them claiming to have taken a picture of a black hole, before they actually took it. Maybe some channel that believes the world is flat and run by lizards made a video about this. Not one that actually tries to be up to date and also be as correct as possible.
