Robert sent in some interesting links, such as https://phys.org/news/2021-12-millipedes-big-cars-roamed-northern.html ... millipedes as big as cars roamed northern England. The link has an image which shows a sandstone boulder with a fossilised section of a giant millipede within it - caught up in sand during a catastrophic event [or the discarded casing of a millipede that was later fossilised, as in the interpretation given]. He dates the millipede to the Carboniferous period, famous for its coal measures, around 326 million years ago on the geological column.

Thunderbolts posted their piece a couple of days ago - see yesterday's post on astronomy,, and here we are on Wednesday with a brilliant view of Comet Leonard with a sensational tail - knots and swirls of debris flowing the comets tail. A small telescope reveals a very complex and dynamic tail who photographed the comet from the Atacama Desert in Chile. Long exposure is uselss says another photographer of the comet - the comet's tail is moving so rapidly. The shapes are sensational. The image below was taken from a farm in Namibia.

At https://phys.org/news/2021-12-astronomers-spy-quartet-cavities-giant.html ... astronomers have found four enormous cavities, or bubbles, at the centre of a galaxy cluster, using NASA s Chandra X-ray Observatory. It is speculated this may have been caused by eruptions from two supermassive black holes - closely orbiting each other.

You may wonder why black holes are a favourite topic on this site. The big question though is - are astronomers misinterpreting what they see in their telescopes? Are their models as whacky as the Covid 19 models?

Gary sent in this link www.yahoo.com/news/why-sand-mafias-forming-science-124003906.html .... William actually sent the link to Gary who forwarded it on to SIS. The mainstream theory is that weathering creates sand. Rocks break apart from frost and heat and continue to break down piece by piece until they are the size of sand granules. Wind and water play a role in this process. There is, or there should be, an unlimited supply of sand on earth. The gradualist models virtually guarantee it. Facts, however, are sometimes stranger than fiction.
