    Default 0t----the roundest round-------bending Einstein

    authorization to confirm components of einsteinian general relativity
    via zero gravity probing was given green light in 1959

    45 years and 750 million usd later witnessed the physical experiment
    initiation with launch of Delta II rocket--2004-- containing the most perfect spherical
    objects ever dimensioned--niobium coated quartz

    and yes---Einstein theory was again confirmed using physical/mechanical metrology---
    but, radiowave timing analysis proved to be 150 times more accurate

    I thought the new kilogram standard silicon spheres being ground to shape in Australia were more spherical: 8 feet out of round if scaled to Earth's size versus the 12 feet of the gravity probe B gyro spheres.

    When you say, "...being ground to shape in Australia", weren't those done a dozen or so years ago? Is there a new, current effort underway?

    As far as I know, no. And those kilogram reference spheres were what came to my mind too when the gyroscope balls were labeled as "roundest", but perhaps from an actual size, not scaled standpoint, they would have a lower nanometer deviation than the silicon balls.

    What's the point?

    Einstein was wrong.
    The earth is flat.
    Aliens are in Area 51.
    No one was ever on the moon.
    The gov't killed JFK.
    The WTC collapsed by design........

    The articles in the original post scaled the object to Earth's diameter for direct comparison so I stuck with that. We are talking about "roundest" so I think scaling both objects to the same relative size is valid.

    Their work to define the SI unit for Molar weight was ready by 2016 and was voted on as a standard in late 2018. Gravity Probe B finished in 2011, 5 years earlier so that would make the Avogadro Project younger.

    I would much rather those resources be spent on finding a cure for cancer, Alzheimer's, and Epstein barr.

    Understanding general relativity is rather important to our everyday lives. No general relativity, no GPS. If you don't do basic research, you don't get any of the good things that come from it later.

    The Avogadro project is extremely important to chemistry....you know, the stuff medicines are made from.
