[amsat-bb] Event Horizon Telescope

[Robert McGwier]

During his career developing techniques with his team to do Very Long
Baseline Interferometry using widely separated but not connected radio
telescopes, Tom Clark, K3IO  made major contributions to Radio Astronomy
Science and Engineering.

Today, we saw another outcome. NSF, EU, and many others announced the VLBI
generated image of the 4 billion solar mass Black Hole at the center of the
Galaxy Messier object 87 (M87 for shorthand). You could literally see all
the way down to the event horizon.  The used telescopes all over the world
and made the signals coherent even though they were recorded using a record
and timing process developed by Tom and his team at NASA Goddard and
extended into the modern era with better toys than Tom had when he was the
world's most accurate geodicist.

And once again, Einstein's theory of relativity was proven right in the
most violent laboratory ever "seen".
