    Seems like no one actually cares about this thankfully, but what actual, tangible proof is there that it even is what they say it is? Some BS equations or something?

    Oh boy, here comes the Creationists. We can't have a single scientific discussion without SOMEONE coming in to peddle that old tired idea.

    OT: pretty cool. Now we just need to develop an actual camera that takes a visible light photo instead of sensors picking up various infrared and ultraviolet wavelengths to generate an image.

    I can't believe that the first thing that crossed somebody's mind when they saw this piece of science was if taxpayer dolladollaz were spent correctly on it. I'm sorry, but this had to be said.

    Its much harder to peer into the core of a galaxy than to get a bunch in one shot. M87, the galaxy those to view, is about as wide as our but ~4 times as massive. 4x the stuff in the same amount of space. We can barely see the core of our own galaxy. Now try to view the core of a galaxy 53 million light years away with 4x the stars/gas to look through. Then you have to isolate the event horizon the of the black hole in a swirling disc of gas bright than our sun. Scientist had to come up with completly new algorithms just to get a chance of viewing this thing.

    52 million light years is a good distance. I wouldn’t want to get sucked in.

    but idk, i feel like it has to be made of something we don't know the name of yet. some kind of substance, like neutron stars are made of. a teaspoon of neutron star matter weighs like a stupid heavy amount, i can't remember exactly how much(it's been a while since i watched that documentary).

    considering a black hole is a collapsed star, it's probably pretty similar to the stuff a neutron star is made of. or maybe it is the same stuff, just in greater quantity. meaning it would be as big or bigger than our sun.
    Neutron star is already a good guess I'd say. We are waaayyyy beyond fusion in those already, thus I'd be very surprised if any occurs in a BH. It's even more strange. BHs are generally considered to be a singularity - a literal point where all the stuff has collapsed into infinitesimal size. But somehow I'm not 100% on board with this. I would think it's more like just a step further than neutron star - a quark ball maybe.

    The thing to be impressed about is that this is the first 100% direct proof of them being pretty much exactly what decades of theory have predicted them to be. This is the confirmation of hundreds of thousands of hours of work by really many people, and the fact that the expectations of what something THIS extreme would look like are met means that we actually got a lot of stuff rather right so far. Not perfect, still details missing, but we seem to be close enough to even make the math work in the edge cases. This wasn't as certain as it is now, thanks to this project. I find that rather impressive.
    Not to mention the amount of coordination and colaboration that was needed to make this happen. That's also impressive on an entirely different level.

    Actually, yes. See my reply to Ghostpanther.

    The only thing more dense than this black hole is some of the peanut gallery that frequents this forum.

    This is really impressive.

    Can someone explain why it's so significant though? Apart from that it was very difficult to do, or that someone came up with an inventive method for doing it that previously was thought impossible.

    its significant because its hard proof that black holes actually do, in fact, exist
    We cannot go back. That's why it's hard to choose. You have to make the right choice. As long as you don't choose, everything remains possible.

    This YT channel never ceases to amaze me. Dereck Muller does a phenomenal job in taking such a complex subject and explain the basics to a (mostly) understandable video. It highlights how groundbreaking it is that we can capture an image of M87's black hole.

    Actually at that density even the most fundamental particles collapse, and as such fusion as we know it is impossible since there are no atoms to fuse. The density is larger than even electron degeneracy pressure, and we know of no other force that would stop the collapse, meaning that, according to our models all the matter would collapse into an infinitely dense point.
    What we see is the shadow of the event horizon, the region of space where gravity becomes so strong light gets redshifted into oblivion, not the actual object that causes the black hole.

    Of course you will not remember because you just simply do not care.
    Personally i was following the whole EHT news since it was introduced and yesterdays press conference was really, really exciting for me and many other astronomy fans. And yes - i will remember this day untill my end probably.

    They will release collected data and papers really soon so it can be checked.

    Sadly it is probably not going to happen due extinction.

    anyway, it's pretty cool looking. but you know, it's probably just a super tiny little hard rock that weighs a shit ton, right? it's a shame, but i doubt it's a "hole" in space.

    if they are a hole, that's got some interesting implications.
    Make sure not to call the police if you get robbed or carjacked or something, cause you know ... ratting the robber out would make you worse than them .. oi

    Anyways, objects with mass curve spacetime. Black holes are so massive that they curve spacetime to the point physics cannot explain them. The term "black hole" is just something they call it ... like dark energy, or dark matter .. it does nothing to accurately describe what they actually are.

    and yes, it is momentous to finally have visible proof of it. i just wish we could actually do something about it, go to it and come back. touch it. it's probably a substance we don't know anything about, harder than any other know substance. i'd bet there's nothing in the universe that could break it.
    I doubt there will ever be a time where anyone, or anything could interact with a black hole. Whether you're pulled apart from gravity, or incinerated by the accretion disk that's a million+ degrees rotating at millions of miles an hour, or have your dna shredded by gamma rays ... the outcome looks grim for studying black holes up close.

    Black holes have not been directly observed. Being directly observed means that theories that predicted them were correct. Not everything has to be visually stimulating to be important.

    It's an ugly photo but the quality of the photo is not what impresses scientists. Before the photo was taken it was already speculated to look exactly like this, and the fact that it does in a way proves that black holes actually exist, which might sound stupid but until now we didn't have a proof as strong as this one.

    You can't say the big bang was an accident either, we don't know enough about it. For all we know a million big bangs happen every second.

    Surely an object of that size and density must be effecting our solo system... nay our galaxy's orbit around the universe?

    Amazing news though.

    This thing is so far away we are there are literally bigger fish to fry.


    Still a great job!
