The Gravitational-Wave "Revolution" Is Underway - Scientific American


Was there recent talk of Einstein's "general relativity"?

Yes, there was.
It all dropped on us, as it were, as if by gravity -- at the speed of light.
Read on....

At the Scientific American, Jonathan O'Callaghan tells us that:

The Gravitational-Wave “Revolution” Is Underway

writing in this regard as follows:
"The first neutron star merger observed by LIGO and Virgo [...] has helped researchers probe some fundamental aspects of the universe itself. Christopher Berry from Northwestern University notes that gamma rays from the event were detected by other telescopes 1.6 seconds after the gravitational waves, which allowed for an unprecedented test of the speed of gravity versus the speed of light. “We’d expect a little difference in their arrival time because they weren’t necessarily created at the same time,” he says. “But the fact that it was 1.6 seconds allowed us to test that the speed of light and the speed of gravity really are the same thing, as predicted in general relativity.”
As the fourth anniversary of the first detection approaches, the field continues to mature—with a bright future ahead.""

    Both book volumes contain the following basic book description:
    "Alice Cunningham Fletcher observed in her 1902 publication in the American Anthropologist
    that there is ample evidence that some ancient cultures in Native America,
    e.g. the Pawnee in Nebraska,
    geographically located their villages according to patterns seen in stars of the heavens.
    See Alice C. Fletcher, Star Cult Among the Pawnee--A Preliminary Report,
    American Anthropologist, 4, 730-736, 1902.
    Ralph N. Buckstaff wrote:
    "These Indians recognized the constellations as we do, also the important stars,
    drawing them according to their magnitude.
    The groups were placed with a great deal of thought and care and show long study.
    ... They were keen observers....
    The Pawnee Indians must have had a knowledge of astronomy
    comparable to that of the early white men."
    See Ralph N. Buckstaff, Stars and Constellations of a Pawnee Sky Map,
    American Anthropologist, Vol. 29, Nr. 2, April-June 1927, pp. 279-285, 1927.
    In our book, we take these observations one level further
    and show that megalithic sites and petroglyphic rock carving
    and pictographic rock art in Native America,
    together with mounds and earthworks, were made to represent territorial geographic landmarks
    placed according to the stars of the sky using the ready map of the starry sky
    in the hermetic tradition, "as above, so below".
    That mirror image of the heavens on terrestrial land is the "Sky Earth" of Native America,
    whose "rock stars" are the real stars of the heavens,
    "immortalized" by rock art petroglyphs, pictographs,
    cave paintings, earthworks and mounds of various kinds (stone, earth, shells) on our Earth.
    These landmarks were placed systematically
    in North America, Central America (Meso-America) and South America
    and can to a large degree be reconstructed as the Sky Earth of Native America."
