  1. If immersed in a bright region, like a disc of glowing gas, we expect a black hole to create a dark region similar to a shadow — something predicted by Einstein’s general relativity that we’ve never seen before, explained chair of the EHT Science Council Heino Falcke of Radboud University, the Netherlands. "This shadow, caused by the gravitational bending and capture of light by the event horizon, reveals a lot about the nature of these fascinating objects and allowed us to measure the enormous mass of M87’s black hole."

    Amazing. Just amazing.

    The EHT observations use a technique called very-long-baseline interferometry (VLBI) which synchronises telescope facilities around the world and exploits the rotation of our planet to form one huge, Earth-size telescope observing at a wavelength of 1.3 mm. VLBI allows the EHT to achieve an angular resolution of 20 micro-arcseconds — enough to read a newspaper in New York from a sidewalk café in Paris [6].

    This is the highest purpose and best use of Humanity's creative potential, as far as I'm concerned. Fuck your Big Beautiful Wall you simpleton.

    1. When the two ALMA prototype antennas were decommissioned at the VLA site, one of them was installed on Kitt Peak AZ to refurbish the old Submillimeter Telescope, and the other was shipped to Greenland, ostensibly to form the N-S Chile/Greenland baseline for the EHT. Not sure what the final configuration was, but that was the plan last I heard.

        1. Aha, thanks! Glad you dialed in on this one. Didn't know the disposition of the prototypes, I just assumed that they were decommissioned or shipped out to the high Atacama desert.

  2. When the stars threw down their spears
    And water'd heaven with their tears:
    Did he smile his work to see?
    Did he who made the Lamb make thee?

      1. The lit textbooks say "stars threw down their spears" means the gods stopped fighting, whereas I always saw it as the "spears" of light that stars throw down upon us. Nobody got more meaning in fewer simple words than ol' Bill Blake.
