    Time Dilation: Discussion with Grok (Elon Musk's AI Device)

    At the rate humans are declining, I expect the machines to take over probably next Thursday, which is bad because that's my bowling night and they might ban bowling as "inhumane to the pin setting device".

    The site appears to be alive but unused. Without a moderator it would be a free for all.

    Space.com Forums Closure

    Way back in "the olden days" of SDC (2002-2012), moderation was very strict about "against the mainstream" stuff in the regular forums. If you made a claim you were expected to provide a reference. ATM stuff was in a separate forum which was easy to ignore if you wanted to. Such a high level of...

    Space Compression Theory of Gravity

    This condundrum is part of the reason Einstein came up with Special Relativity. He knew from Maxwell's equations that the magnetic field arose only when a charge was moving relative to the observer. If you ride down the street in a car with an electron driving, you cannot measure a magnetic...

    I am sorry to hear of the forums closing down, I've enjoyed my time here at the SDC forums and look forward to them returning some day.

    Question Earth Moon Origin

    With vastly increased computing power "just around the corner" perhaps we can model every conceivable combination of solar nebula elements, etc etc and see just how often life arises. I think life is ubiquitous where there is water. I don't go with other solvents, water is just too unique in so...

    Keeping The ISS In Orbit

    The elasticity measuring apparatus would certainly have been immersed in the liquid helium along with the sample. Everything would have to be at the same temperature to prevent movements. It takes a very tough material to withstand the thermal shock of immersion. Stainless steel works OK. Teflon...

    Keeping The ISS In Orbit

    Six years ago this was published, showing a flexible graphene foam for use in space, flexible in liquid helium at -269°C. https://www.sciencenews.org/article/new-graphene-foam-squishy-coldest-temperatures

    EML‑Core Mk I

    This is a possible method. One thing not taken into consideration is the conservation of momentum. If large masses are sent to Mars, other large masses must be sent in the other direction. The rings would move backwards by an equal amount of momentum.

    Keeping The ISS In Orbit

    Steel has no good use in space in strength structures. Too many far lighter alloys with similar strength.

    Hubble Tension explained (including its value) by the two phase cosmology

    I will defer to the principle of conservation of mass/energy. Stuff can't just "go away". There would be evidence, like a giant flash of light for example.

    New scientific calculator

    360 has 24 divisors. This is very handy for navigation purposes, for dividing round things up. The ancients probably knew this. From Wiki: "360 is the 13th highly composite number, and one of only seven numbers such that no number less than twice as much has more divisors; the others are 1, 2...

    Question Earth Moon Origin

    In essence, this reports on the weather at the core/mantle boundary, complete with mountains.
