It's not an actual hole...just a super dense object. Everything it gobbles gets compacted and added to it.

send a probe thru it? May get a quick glimpse before it is destroyed.

The gravity tears apart entire stars before they even get close to the horizon...

Things like this really make wonder what the purpose of all this truly is! I have to say the theory of 'intelligent design' seems correct with each new discovery.

No. Even if a probe could survive (which it couldn't) and go through the event horizon, it could not send any information back through the event horizon. The event horizon is the point beyond which nothing, not even light, can escape.

Indeed, evidence. Something that stands out visually.

The image aligns with expectations of what a black hole should look like based on Einstein’s general theory of relativity, which predicts how spacetime is warped by the extreme mass of a black hole. The picture is “one more strong piece of evidence supporting the existence of black holes. And that, of course, helps verify general relativity,” Will says.
It's a cool picture, but still no hard proof, so no one is really sure exactly what it is, never mind replicating it under controlled conditions time and time again and getting the same result each time.

Either way, continues to make nice fodder for philosophical speculation.

Good explanation for the fuzzy image.

Black "hole" is such a weird name for the singularity because it makes people think that the disc is empty (see the previous comments), but as others already indicated the center is actually a dense object that feeds on anything that's caught within the event horizon and grow and grow and grow. It should be renamed to Black Mass or Black Ball of Doom instead.

Correct, here is a great video visualizing the mass of black holes.

This is what makes people skeptical about scientists these days. That's not an actual image although they are leading you to believe it is. The telescope arrays used don't take pictures they are radio telescopes. That is a computer generated image with the code to generate it written by humans so it's actually a human interpretation of the radio wave data. I find it quite ironic that the generated image looks pretty much exactly like the theoretical drawings and what you see on the science channel. If you go back and look at all other theoretical drawings and then the real actual photo, take Pluto for example, the drawings were close but wrong. That leads me to believe that this is wrong also. Close, absolutely but this is NOT a real photograph. Everywhere on the internet today you are seeing articles saying this is an actual photograph. It's not. The article in the OP says the same thing. No mention that it is radio wave data that was transformed into an image with a computer algorithm which ultimately is a human interpretation and not an actual real image. It's really cool but it's not all that groundbreaking. The data has been available that tells the story of black holes for a while now, the only new thing is the image generated, which again is most likely not 100% accurate and just a human interpretation of the data that was made to look like the theoretical images. It would be really groundbreaking if it actually WAS a real photograph.
