    Prof. Dr. Marc Kamionkowski
    (Johns Hopkins University),

    Heinrich Hertz Lecture 2024.

    The past quarter century has been a period of rapid
    progress in our understanding of the origin and
    evolution of the Universe. We now have a simple
    mathematical model that can account for the gross
    features of our Universe as well as detailed informa-
    tion from precise measurements and observations.
    The model requires, though, several ingredients,
    such as dark matter and dark energy, that are not
    to be found within our current understanding of
    the fundamental laws of physics. There has also
    emerged, in the past few years, some inconsistencies
    between various measurements. In this talk, I will
    describe the triumphs of our current cosmological
    model, as well as its shortcomings.
