Earth-Sized Telescope Just Took The First-Ever Photo Of A Black Hole: How It Will Test Theory Of Relativity
Ten nights of staunch observation may have led astronomers to successfully peer inside a black hole and take an image of its event horizon, or its point of no return.
Einstein’s theory notes that all the information crossing a black hole’s event horizon gets lost forever. Yet according to quantum mechanics, information can never be lost.
Despite the long wait and other external factors, the team remains optimistic. Falcke said that even if the images emerge as “crappy and washed out,” they can help test basic predictions of Einstein’s theory in the extreme-physics environment of a black hole.

Made my brain hurt.
I read that one too. Hard to wrap your mind around it all.
“Earth-Sized Telescope”?
it would take up the whole earth, or be the size of the earth but hanging off one spot of the earth - it doesn’t make sense to me.
Look up VLBI, very long baseline interferometry. While the image made from a few distant apertures (say, spanning a circle of 7000 miles diameter, e.g. the Earth) will have large diffraction artifacts that would be absent in the image of an image taken with an actual 7000 mile diameter telescope, the former image will nevertheless have features that are comparable sharp to those in the latter image. These sharp features can be extracted from the image, with the result that a sharp image can be constructed as if an actual 7,000 mile diameter telescope had been used.
Einstein has not EVER been proven wrong; theoretical physics shalt NEVER be the same...
Einstein ping!

Funny, that’s exactly how I imagined it would look.
It will be 2018 before any type of image is available.
I read it. I just really struggled with it, and didn’t retain much.
Seen “Contact”, the movie? Array of dishes spread out on a plain that gathers much more information than a single small dish. Same principal, although the “small” single collection “dishes” are on different continents, and their information is combined into a whole.

Lost as far as we are concerned, but the ensuing Universe the data winds up in will just do it again. Get to know Jack...

That is an old photo of a black cat in a coal bin at midnight.
Sleeping with eyes closed.
What’s all the fuss? We’ve been staring at a Black Hole for 8 years.

Just like high school....
so the telescope is to really earth sized, but the images it can see are?
I’ll look it up more tomorrow. thanks.
I thought it would be pink on the inside at least
Where is the pic?
Yeah, the “eyepiece” portion of the telescope is sort of Earth sized, but missing a lot of information that is interpolated and added in by computers. Even then, because the Earth is so tiny relative to other celestial bodies, the image gleaned is not much better than what we already see. It’s better, but not by much. I think it’s going to be centuries before we get a good idea of what a Black Hole really looks like. By then, we may have a telescope array as large as our solar system.
Premature adjudication.
The VLA out in the plains of San Agustin in New Mexico. Beautiful area! I used to hunt around the town of Datil just west of there, and in the mountains to the north.
