27 Mar 2021 Even Big Bang is Changing This piece is sort of accusatory, critical of the reader, shall we say. If you thought the bang in the big bang was a bang and then you have misrepresented the Big Bang lobby. It is not them that have changed their view of the bang but we folk who thought the bang was an explosion. Mainstream revise their consensus theories all the time - and now it is the turn of the astrophysists. However, instead of telling us there was a mystery all the time, one they didn't bother telling the audience about, we have a different kind of approach. It is our misconception that is at fault. |
22 Mar 2021 Coppersmiths in ancient Wisconsin Hunter gatherers living beside Eagle Lake in Wisconsin manufactured 10cm long projectile points [otherwise known as arrow heads] out of pure copper. They were probably hammered into shape after heating the metal but this illustrates that copper was used by different people, fairly early in the Holocene. In this case, over 8000 years ago.

22 Mar 2021 A Cave Beneath the Waves William sent in this fascinating linke - www.yahoo.com/news/man-discovered-worlds-only-prehistoric-170923922.html ... a French diver, back in 1991, found a submerged entrance into a cave near Marseille. He claimed it had prehistoric paintings of penguins and seals, something never recorded from previous cave art. It seems that so called experts based in Paris dismissed the idea of marine life depicted on cave walls, considering it provincial fancy. However, the metropolitan specialists now have egg on their face as the diver was speaking the truth. |
22 Mar 2021 Upending Vertebrate Origins At https://phys.org/news/2021-03-long-accepted-theory-vertebrate-upended-fo... ... the long accepted theory of mainstream vertebrate origins is taking a bashing by some paleontologists it would seem. This comes after the discovery of fossilised fish larvae - rather, lamprey larvae. It is dated 360 million years ago - even a long time in geological time scales. The research is published in the journal Nature - see https://doi.org/10.1038/s41586-021-03305-9 .. |
21 Mar 2021 crater is not a crater At https://phys.org/news/2021-03-world-oldest-crater-meteorite-isnt.html ... in 2012 University of Waterloo scientists claimed to have discovered an impact crater. Zircon crystals in rocks are thought to preserve ancient damage done by shock waves, we were told. There was also evidence of rock melt - rocks that recrystalised. This is known as metamorphism. Since then, the region has been investgated for minerals, under close examination. It is now thought a meteor impact was not involved - but see also https://doi.org/10.1016/j.epsl.2020.116730 |
21 Mar 2021 Curious Cloud Robert sent in the link ... www.esa.int/Science_Exploration/Space_Science/Mars_Express/Mars_Express_... ... and the full paper is at https://arxiv.org/abs/2103.03919 [which is the abstract but when there click on the pdf] ... the discovery of a curious cloud formation which forms around a Martian Vlocano. The explanation given is moist air, on the dry planet. Robert suggests an electrical cause, reminiscent of Martian Dust Devils. |

13 Mar 2021 Antarctic Magnetic Link to Gondwanaland Robert sent in the link to https://phys.org/news/2021-03-antarctica-magnetic-link-ancient-neighbors... ... researchers have magnetically linked Antarctica to its former status as part of Gondwanaland. The eivdence is derived, in part, from ESAs Swarm satellite mission -as well as aeromagnetic data from geological sources. The idea is to reveal the mysteries beneath the massive and thick Antarctic ice sheet. We may note that Gondwana was composed of South America, Africa, Madagascar, the Antarctic, Australia and New Zealand, as well as India. |
