coordinated with atomic clocks to synchronize and all that data is combined after the fact into what s called a correlator and that correlate or ultimately produces data that can be constructed into an image. astronomers want to explore how matter can disappear from our world for ever and to take a deeper look into einstein s theory of relativity and its initial theory on black holes. this fascinating stuff and it s easy to see how this is kind of a dream come true for the scientists involved explain to us if you can in layman s terms i mean how were they able to capture this extraordinary image into it it s quite tricky because a black hole is massive and this specific black hole is six point five billion times the mass of our a sun it s really really huge but it s small in size i mean it s massive it s small
