Accurate to one second in ten million years?   A watchmaker's dream.

One of the scientists did say though that they weren't going to wait 10 million years to test it LOL.

Hi,

Kinda strange for me to see these images ... because the physics behind it would suggest that if you can see it, you ARE under its influence, and before you can write it down and tell your friend, it would have already swallowed you up!

Thus, if seeing is believing, then it's over!

The thing is that you probably couldn't see it. These images are compiled from using transpectral analyses. In other words, compilers of these images use wavelengths of energy far beyond the miniscule spectrum of visible light. What you say might be true if you were actually near it (as far as we know, much of science is theoretical) but imagery can be obtained by energetic differentials that paint a picture.

^ Oh you can't see it - that's why it's called a black hole. The Human League can explain it - sort of LOL.

Here's a (relatively) recent article about black holes. Really good and interesting.

Well, now they have. The black hole at the center of the Milky Way, know as Sagattarius A*, or Sag A Star for short, has been imaged. https://eventhorizontelescope.org/blog/astronomers-reveal-first-image-black-hole-heart-our-galaxy
