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

KEY OBSERVATION. “The discovery in 1998 of a mysterious repulsive energy, dubbed Dark Energy, and representing more than two thirds of the energy content of the universe, provided the first massive evidence for repulsive gravity.” https://lnkd.in/daA2SgMy View in LinkedIn

THE HOYLE AND NARLIKAR PROPOSAL. “For Hawking, it clearly meant that the theory was wrong, but today, with the knowledge that negative mass solutions are allowed, and the observation of repulsive gravity, it is fascinating to see that the initial Machian perspective of Einstein could effectively be realized in the Dirac-Milne universe.” https://lnkd.in/daA2SgMy View in LinkedIn

A SYMMETRICAL UNIVERSE. “Hawking had noted that the Machian formulation of general relativity proposed by Hoyle and Narlikar only works if there exists equal amounts of negative mass and positive mass particles in the universe.” https://lnkd.in/daA2SgMy View in LinkedIn

SO ENDS this first of two weekends considering Warren Hamilton’s magnetic shield hypothesis of the Cambrian explosion. It is a contribution to tectonics and fossil record ablation that together might start to add up. This period remains one if biology’s most unconvincing stories and has certainly been influenced by cherry-picking geological data. https://www.sciencedirect.com/science/article/pii/S0012825219302636?via=ihub View in LinkedIn
