CROSSING THE LINE. “Dubinski et al. the evolution of underdense regions, which expand and lead to large “voids” that occupy the largest fraction of our universe, could be described as the evolution of negative mass particles violating “maximally” the equivalence principle.” https://lnkd.in/daA2SgMy View in LinkedIn

REANALYSIS. “Motivated by the fact that our universe shares several aspects with a coasting universe, we have studied structure formation in universes involving equal amounts of negative and positive mass, with a particular emphasis on the Dirac-Milne cosmology.” https://lnkd.in/daA2SgMy View in LinkedIn

“One of the Milky Way’s premier star factories is the Carina Nebula (NGC 3372), which came to life about 3 million years ago when stars first ignited in a cloud of molecular hydrogen. In this view, jets of gas erupt from infant stars emerging from their birthplaces.”" " https://lnkd.in/dVvuFFPY View in LinkedIn

A Caganer (Catalan pronunciation: [kəɣəˈne]) is a figurine depicted in the act of defecation appearing in nativity scenes in Catalonia and neighbouring areas with Catalan culture such as Andorra, Valencia, and Northern Catalonia (in southern France). It is most popular and widespread in these areas, but can also be found in other areas of Spain (Murcia), Portugal, and southern Italy (Naples)." " https://lnkd.in/dkEcYBAS View in LinkedIn

CALL FOR CORROBORATION. “The authors document the methodological and statistical criteria for these determinations and recommend that analogous investigations be conducted elsewhere.” https://www.sciencedirect.com/science/article/pii/S0012825219302636?via=ihub View in LinkedIn

EXPECTATIONS. “Whatever the experimental results, they will have important repercussions on our understanding of the evolution of our universe.” (The end of this exciting paper). https://lnkd.in/daA2SgMy View in LinkedIn

TANTALIZING DATA. “The Phanerozoic polar-wander curve for stable Europe is well established. Strikingly, Bazhenov et al. demonstrated that nearly all paleomagnetic poles for Precambrian rocks 600 to 1700 m.y. old from the Fennoscandian and Ukrainian shields and the western Urals lie so close to that curve as to make random overlaps of independent “Precambrian” and Phanerozoic curves unlikely (Fig. 32c).” https://www.sciencedirect.com/science/article/pii/S0012825219302636?via=ihub View in LinkedIn

FRAGMENT FROM NATURE continues from last weekend and concludes this weekend on the extraordinary efforts of Professor Warren to change a geology paradigm that probably helped explain the Cambrian explosion 600 million years ago, and how entrenched dogmas resisted his work. https://www.sciencedirect.com/science/article/pii/S0012825219302636?via=ihub View in LinkedIn

SHAPE OF THINGS TO COME. “Images of the Eagle Nebula show the Hubble Space Telescope's ability to capture pictures in both visible (left) and infrared (right) light. NASA is celebrating the successful restart of the telescope's payload computer, opening the door to more observations.”" " https://lnkd.in/ddZZNyaT View in LinkedIn
