586 Million Year Cycle in Geology Matches Galactic Super-Cluster Spacings

submitted by: RayTomes
The longest geological cycle identified is described as about 600 million years in "Megacycles", the proceedings of a geological conference, Edited by G Williams. However Prof S Afanasiev of Moscow has determined the cycle very accurately to be 586.24 million years using his Nanocycles Method. It so happens that cosmologists, Broadhurst, T.J., Ellis, R.S., Koo, D.C. & Szalay (Nature 343, p 726) have observed regular mega-walls of galaxies at spacings that they describe as 128 Mpc/h,...

Hubblecast 01: Hubble sees 'Comet Galaxy' being ripped apart by galaxy cluster

The NASA/ESA Hubble Space Telescope, in collaboration with several other ground- and space-based telescopes, has captured a galaxy being ripped apart by a galaxy cluster's gravitational field and harsh environment. The finding sheds light on the mysterious process by which gas-rich spiral-shaped galaxies might evolve into gas-poor irregular- or elliptical-shaped galaxies over billions of years.
