It certainly makes a whole new meaning of post processing. -- Regards, Savageduck |

I think today the best telescopes may be able to image over 4 pixels 1/50th of an arc second, but I'm not sure. In any case, there is too much interposed dust between us and the galactic centre to allow an optical image. The 'Dehaze" slider in LR works real well. -- Regards, Eric Stevens |

It's not the "image" that is too big. It's the collection of data that is eventually processed to make the image that is too big to transmit. The array is not recording "images". It's recording information that describes the signal at a particular time. (VLBI). -- "2/3 of Donald Trump's wives were immigrants.

snip Yes, I got interested for nothing. Even so, a black hole surrounded by matter in-falling into the singularity (which don't really exist since string theory is true) would likely only show as a glowing sphere (the matter in-falling) and would not show some black abyss. Please cite your authority, and/or calculations to prove that the string theory is true. We await with bated breath. If what you say is true, why is it still called a "theory." Just asking. -- PeterN |
