    Fingerprints of the Dark Universe in Geoscience
    (Springer Nature, 2024) Zioutas, K.; Anastassopoulos, V.; Argiriou, A.; Cantatore, G.; Cetin, S.; Gardikiotis, A.; Guo J.
    Dark matter (DM) dominates our universe, while its nature remains unknown. To unravel its composition is of fundamental importance for all physics. The solid Earth, with its atmosphere, could be the new target and detector of “invisible matter”. Any not well-understood dynamical behavior is of potential interest, e.g., the anomalous annual temperature excursions in the stratosphere and the global electron content of the Ionosphere (with its anomalous behavior around December-January known since 1937) also show planetary relationship, which is the ultimate signature for streaming DM involvement. Because this to happen is not expected within known physics, since a remote planetary tidal force is extremely feeble to cause any noticeable impact. Following this reasoning, here we present novel results combining the dynamical behavior of spatiotemporally occurring atmospheric activity with inner Earth activity like earthquakes. This finding should encourage geoscience to make the Earth the as-yet overlooked observatory for (streaming) DM, even parasitically, because Earth’s dynamic atmosphere and seismic activity are monitored continuously for other reasons. Of note, such an endeavor would be a natural extension of using the Earth to detect conventional cosmic rays. Exotic cosmic particles like anti quark nuggets, magnetic monopoles, and hidden-sector photons are among the most promising candidates. Other as-yet unpredicted DM constituents could make the surprise. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

    Novel Planetary Signatures from the Dark Universe
    (Springer/Plenum Publishers, 2023) Zioutas, K.; Anastassopoulos, V.; Argiriou, A.; Cantatore, G.; Cetin, S.; Gardikiotis, A.; Haralambous, H.
    Dunkle Materie (DM) came from unexpected cosmological observations. Nowadays within our solar system, diverse observations also defy conventional explanations, like the main physical process(es) underlying the heating of the different solar atmospheric layers. Streaming DM offers a viable common scenario following gravitational focusing by the solar system bodies. This fits as the underlying process behind the solar cycle, which was the first signature suggesting a planetary dependency. The challenge, since 1859, is to find a remote planetary impact, beyond the extremely feeble planetary tidal force. We stress the possible involvement of an external impact by some overlooked streaming invisible matter, which reconciles all investigated mysterious observations mimicking a not extant remote planetary force. Unexpected planetary relationships exist for both the dynamic Sun and Earth, reflecting multiple signatures for streaming DM. The local reasoning a la Zwicky is also suggestive for searches including puzzling biomedical phenomena. Favourite DM candidates are anti-quark-nuggets, magnetic monopoles, dark photons, or the composite pearls. Then, anomalies within the solar system are the manifestation of the dark Universe. The tentative streaming DM scenario enhances spatiotemporally the DM flux
