TOXIC COMBINATION. “We have stone age emotions, medieval institutions and god-like technology.” (The late Professor EO Wilson, a giant among men). https://www.theguardian.com/environment/2021/dec/27/edward-o-wilson-naturalist-modern-day-darwin-dies?CMP=Share_iOSApp_Other View in LinkedIn

REMAINING OBSTACLES. “Very strong theorems seemed to exclude any possibility of negative mass particles or objects, or more generally violating the positivity of energy.” https://lnkd.in/daA2SgMy View in LinkedIn

NEW BRIDGES. “By the 1950s, Bondi had built negative mass solutions that respected the equivalence principle.” https://lnkd.in/daA2SgMy View in LinkedIn

LATER CONCLUSIONS. “But rather obviously, these studies had assumed that matter and antimatter had both a positive gravitational mass. Today, the discovery of a repulsive gravity through observations of SN1a supernovae luminosity distance, called Dark Energy, leads us to be more cautious: indeed, what seemed previously impossible, repulsive gravity, is the major topic of interest in cosmology.” https://lnkd.in/daA2SgMy View in LinkedIn

WARREN HAMILTON. “Warren B. Hamilton, PhD, Geology, is Distinguished Senior Scientist, Department of Geophysics, Colorado School of Mines. For 43 years he worked at the U.S. Geological Survey. He was an author in over 100 refereed articles from the 1950s to the present, and in 1989 he received the Penrose Medal, the Geological Society of America's highest award.” https://lnkd.in/d8kyQ4xj View in LinkedIn

ONE SAMPLED DATA SOURCE. “Testing, which I do not attempt, is desirable to confirm or reject that hypothesis. Purported Archean paleomagnetic data are so sparse in time and space, the dating of remnant magnetization so ambiguous and orientations so scattered, as to presently add little to the debate. There are, however, many hundreds of purported determinations of magnetic orientations of Proterozoic rocks.” https://www.sciencedirect.com/science/article/pii/S0012825219302636?via=ihub View in LinkedIn

MAGNETIC SHIELDING AND CAMBRIAN EXPLOSION. “The Phanerozoic has been the era of plate tectonics. Lithosphere motions documented by paleomagnetism suggest Earth’s dipole magnetic field may have developed at ~600 Ma. The Cambrian explosion in which most modern phyla evolved may have required its shielding against radiation.” https://lnkd.in/d8AxQ-kU View in LinkedIn

ORIGIN OF MAGNETIC SHIELD. “Earth's internal strong dipolar magnetic field may have developed in its present form only about 600 m.y. ago after a long hiatus without such a field or with one that was much weaker or more complicated.” https://www.sciencedirect.com/science/article/pii/S0012825219302636?via=ihub View in LinkedIn

FRAGMENT FROM NATURE features the work of the geologist, the late Professor Warren Hamilton, who undertook a new and radical explanation for the Cambrian explosion some 600 million years ago, in an attempt to overturn dogmatic ideas prevalent at the time. The Cambrian explosion has always lacked a convincing story and this may be a compelling part of it, combined with global flooding wiping the older fossil record clean. View in LinkedIn
