EARLY CONCLUSIONS. “Glashow et al. “concluded again that even if the primordial universe had succeeded in creating a symmetrical world between matter and antimatter, diffusion of matter and antimatter at their domain boundaries would lead, as soon as the Universe becomes transparent, to an annihilation between matter and antimatter in conflict with observational limits, unless the domains of matter and antimatter had a size exceeding several billion light-years, which seems unrealistic.” https://lnkd.in/daA2SgMy View in LinkedIn

INCONSISTENCY. “Indeed, if matter and antimatter have both positive gravitational masses and respect the equivalence principle, matter-antimatter annihilation continues to occur after the Universe has become transparent, leading to a diffuse high energy gamma-ray background, already difficult to justify in the early 1970s, at the epoch of the SAS-2 satellite, and clearly inconsistent with the much more sensitive contemporary satellites, such as the Fermi satellite.” https://lnkd.in/daA2SgMy View in LinkedIn

SEARCH FOR SYMMETRICAL UNIVERSE. “The conclusion of their study, after several years of effort, was that the primordial Universe, at least in the standard cosmological model, does not provide enough time for a matter-antimatter universe to create structures large enough to evade the constraints of the diffuse gamma-ray flux.” https://lnkd.in/daA2SgMy View in LinkedIn

THE DOMINANT PLANT SPECIES. “It has become traditional to open a discussion of angiosperm origins by quoting Charles Darwin who described the problem as an abominable mystery. But what is so mysterious and so abominable about angiosperm origins is that, after 140 years of research and profuse publication, there still is no light at the end of the tunnel?” https://lnkd.in/dq9cE6j2 View in LinkedIn

EO Wilson. “Ants are possibly as close as we will ever see to what higher social organization might look like on another planet. They communicate almost entirely by smell and taste. They have extremely complicated societies.” https://youtu.be/RcGeewpiCr4 View in LinkedIn

PATCHY DATA. “The database of geomagnetic paleopoles thought to be of Precambrian age is ambiguous and undersampled. Age of magnetization is the most critical and least known parameter and only selectivity of data has enabled consistency with popular conclusions.” https://www.sciencedirect.com/science/article/pii/S0012825219302636?via=ihub View in LinkedIn

TECTONIC SUPERCONTINENTS. “Illustrations have been devised of analogous plate-tectonic activity in the form of disruption and reassembly of hypothetical successive but similar Precambrian supercontinents Columbia and Rodinia.” https://www.sciencedirect.com/science/article/pii/S0012825219302636?via=ihub View in LinkedIn

THE ORIGINS OF THE MYTH. “Because 1970s conjectures that whole-mantle convection and plate tectonics operated throughout most of Earth history dominate paleodynamic literature, studies of the magnetization of Precambrian rocks have mostly interpreted data in these terms.” https://www.sciencedirect.com/science/article/pii/S0012825219302636?via=ihub View in LinkedIn
