  1. Dark-Matter or . . . whatever we may call it – it is unclear yet whether the entity that is causing the inexplicable behavior is matter or nor, but . . .

    the other classic case where it showed up is in a careful study of galaxies moving away from us. We KNOW all other galaxies from the red-shift are speeding away from us and each other at a remarkable rate of speed. The further away, the faster they are receding. So, someone thought up a clever study – to carefully measure the speed. They expected that if they measure carefully enough, they should be able to see that the galaxies are slowly – ever so slowly slowing down – due to gravity. Oopppppssss . . . .They saw the opposite. According to the red-shift data, the galaxies are speeding up.

    Speeding up? THAT made no sense at all. They re-checked EVERYTHING because it just did not make sense. What would be ‘pulling’ a galaxy, or all galaxies – away from each other – at an accelerating rate?

    They have not figured this out, and tentatively they have described the phenomenon as due to ‘dark-matter’.

    There may be several phenomenon that are filed as ‘dark-matter’ – kind of a catchall for stuff we still do not know. It’s interesting and encouraging that aspects of dark-matter are being studied by BU students like Sushkov – some closet somewhere.

  2. I sailed to Greece three times looking at “black matter” at night sailing this 73′ gold-platter preparing to determine our position at sea in early morning and evening sights. GPS existed(1974) but only on “Woods Hole vessel the Knorr.Therefore the paper I wrote for BAC in 1976 whereas I consulted with your “Theosophist Society” about the relationship between interstellar gravitational forces and creationist “The DeStijl Movement” Mondrian type building forms could be influenced by ‘Black Matter since the creation of civilization on this planet??
