    Summary:
    Nuclear clocks would measure time based on changes inside an atom's nucleus,
    which would make them less sensitive to external disturbances and potentially
    more accurate than atomic clocks.
    These clocks could lead to improved timekeeping and navigation,
    faster internet speeds, and advances in fundamental physics research.
    Scientists have demonstrated key components of a nuclear clock,
    such as precise frequency measurements of an energy jump in a thorium-229
    nucleus.

    future babble?
    Paper is 25 dollars measured at today's nuclear inflation time, eh speed
    I would have thought that NIST, financed by public money,
    would publish their papers for free for thee.

    You already mentioned this back in May. This is the follow-up we all
    expected.

    When you come to s^Hthink of it, 'time' is a very interesting thing.

    If we (well 'I') look at clock speed variations in a different gravitational field
    one can wonder if there may be a better way to 'define' time,
    one that does not depend on the present gravitational field. (Le Sage compression in my view).
    Then if we look 'elsewhere' at for example the repeating radio burst or gamma ray bursts from
    stars / space, and possibly from stars / places outside our 'universe..
    Or in a total different way..
    Any ideas?

    Nature is an expensive journal to run and publish. They charge for
    access. This is getting less common many are now free access.

    The paper you want here isn't on arxiv that I can see but this one is:

    https://arxiv.org/abs/2404.13023

    Any university or copyright library will subscribe to Nature - you
    shouldn't have to travel far to find a copy. My UK local library
    provides digital access to many journals, magazines and newspapers.

    It was a side effect of Covid that for health reasons they no longer
    take paper copies of such transient material.

    Cool! got the paper, reading it.
