Is Einstein always right?
after reading the topic i expected something else o.O

Einstein is not always right!
But in this case, seems he has been quite on point.

You're right, but since he tends to be right far more often than I do... It's enough for me :P

I really like the image. I have to take some time next week to read the scientific papers.

I'm excited for this (even if a little less than I was for gravitational waves).
It's huge, so I will take some times too to read papers, in order to better understand what I'm seeing, the work behind it, and the possible future! :D

Do you have any backgroup in radio interferometry? If not observational procedure and processing might be a little difficult to understand.
Just in case, a short version: You observe along small paths (due to Earth's rotation) on a Earth-size plane. You have to Fourier transform these observations to get the image. The less holes are in the plane, the better the image. As you will have hole, you need models to "fill them" (=filter the artifacts in the image domain, after the FT).

Nope, no experience at all to be honest, I'm going in a completely direction of the physics world, but I like to keep an eye on astrophysics. I think I understood the main points of your explanation... Thank you! :D
Now I'll have to find time to study the details... Or I'll try to ask to some astro-friends! :P

In case you (or someone else) don't want to search yourself, the open access papers:

It looks like the Darksign from Dark Souls, which probably means the universe is an undead or something like that.

If the image would be taken at typical security camera distances (a few meters), you could see the scale of individual molecules (if my math is not wrong).
Comment has been collapsed.
Cool! :D
Pixels are a thing these days, so why not xD
Comment has been collapsed.
You could not see the molecules, due to limitations in the diffraction limited (the wavelength of visible light is too large) though.

Damn. I see from your answers that you are very knowledgable in this field! Kudos to you, Oppenh4imer! :)

Well, that's something to be excited about for a scientist and for people interested in space related stuff, but certainly not that much for the general public, at least not with that low quality photo. Maybe when James Webb will be finally in space, that will change.
Comment has been collapsed.
I'm not really sure, but I think that the James Webb telescope has different targets.
BTW it's exciting for one thing: NEVER before we had a real image of a BH. All the images, till now, were just pc simulations. So, until yesterday, BHs could be "fake" - but now we have really seen one. :D
Comment has been collapsed.
Indeed I wasn't really clear. I meant to say that after Webb's launch we will have clearer info, images included, about what's out there and then the general public's perception will change.
Comment has been collapsed.
I was firmly convinced of the existence of BHs (like everyone, I suppose), but after all... Until you don't see something, you can't really be sure that it's real. Even if it's the (extremely) most likely option.

Even if you "see" something, you can only say that your current theory describes your observation, not that it is exactly like your theory says.
E.g. low energies -> protons have no substructure. Neutrons are unstable? -> I have some pion exchange theory (if I remember correctly). Only higher energies will break your reality.
Comment has been collapsed.
Right. Then better say - a new point of view, that further confirms our present theories. :D
Until we see a new breakthrough, or we find the theory of everything.

"Low quality" is relative. Today's image was observed with telescopes that achieved an angular resolution in the sky that is about 1000 times better than what JWT will have (50 micro-arcseconds compared to 34 milli-arcseconds).
As JWT will work in the infrared and EHT works in the radio (mm wavelength) domain, they observe different targets.
I am not sure, how much JWT's images will change the general public's view, as they will be false colour too. The nice thing about Hubble was, that many images were in the visible spectrum, so one could imagine to see the same for oneself, if only one would be there. I don't think there will be that kind of public impact.

I've already found rule 34 pictures of the black hole...

Its quit spectacular to be honest. I dont think many realize that this is first EVER picture of black hole.. Up until now it has been theorized only. Only computer generated simulations.
Even if the picture is low quality its a scientific step. And I hope towards bigger understanding of universe and how its built.
Black holes have always fascinated me.. I just hope ttheres going to be some major scientific breakthrough inn my lifetime

Event Horizon, eh? Not sure you'd want to re-enact that.

Congrats to Einstein and other astrophysicists for creating a theoretical model so accurate that the actual photographic evidence is a bit of a letdown for how predictable its appearance is. :)

That's where we should send the Epic Games Store 😏

thats it ? thats the photo ? where is the focus ? black hole ate it ?
Comment has been collapsed.
You try adjusting the focus knob for precisely 55 million light years.

hold my pinacolada
and have you seen interstellar ? they had quite good pics of black hole

It's size, from this distance, is 40 micro arc seconds. The image was taken by linking measurements from observatories across the globe, creating a virtual telescope the size of the earth. If you want better resolution, you need to have a larger telescope than that.

ive seen i fair share of black holes photos in my life

nope, you saw artworks, illustrations, not photos.

So... Today the photograph of the century was revealed. The Event Horizon Telescope shot the first ever photo of a Black Hole!
The subject: the Bh at the heart of the Messier 87 galaxy, 55 million light years from Earth!
The technique: a network of eight radio telescopes spanning locations from Antarctica to Spain and Chile, whose data was interpolated through the interferometric technique, becoming - from a certain point of view - a singular telescope of the dimension of the Earth!
This is a great period for experimental astrophysics.

A couple of Space-themed GAs, here. Not as Epic as the BH... But that's what I found in the sofa. Maybe something better will come.
