Image of a Black Hole

[flyboy77]

Sorry, I work with a flat Earther and CGI is his response for everything.

Back when, i was a very keen amateur astronomer.....

Without knowing this interferometry game at all well (I had heard the term previously and that's it), I gather in this instance they gather together 8 discreet radio wave signals and by syncing them you somehow amplify the signal.

That amplified signal is then made into an 'image' and hey presto - all with beautiful colour!!

I'm not sure how the radio wave (sine wave?) is converted into an image - but I would suggest there must be a fair dose of CGI in there somewhere!

As for flat eathers, perhaps Matt Kennedy is one?  ;D
