Methane Reservoir

At https://phys.org/news/2019-08-massive-methane-reservoir.html ... link forwarded by Robert (but see also https://tallbloke.wordpress.com/2019/08/21/origin-of-massive-methane-res... ) ... which comes with some useful comments. New findings published in PNAS provide evidence of the formation and abundance of abiotic methane - methane formed by chemical reactions that do not involve organic matter. It shows that methane found on other planets and moons could well have a similar origin. It is no longer a mystery we are told. Abiotic methane exists.

3D Quantum Spin

At https://eurekalert.org/pub_releases/2019-07/ru-pff071519.php ... apparently, there is no way to prove that a three dimensional 'quantum spin liquid' exists. Physicists have come up with another way to persuade their fellows of such a discovery - single crystals of cerium zirconium pyrochlore that contained the right kind of stuff to qualify as the first 3D version of the long sought after state of matter.

Bottomonium Particles

One for the birds. At https://phys.org/news/2019-07-bottomonium-particles-dont.html ... a few millionths of a second after Big Bang the universe was so dense and hot that quarks and gluons (that make up protons, neutrons and other hadrons) existed freely in what is known as the quark-gluon plasma. All hypothetical of course. Apparently, they aim to recreate this situation at the Large Hadron Collider (and some early results are said to be promising) via high energy collisions of heavy ions of lead.

Solar Minimum and Noctilucent Clouds

Two interesting posts on noctilucent clouds and the solar minimum - we are currently at the end of one solar cycle and just entering another. It seems that during solar minimum the atmosphere shrinks and this is why this year, last year, and next year will have lots of noctilucent clouds (just after sunset). In the two links below, 2018 and 2019, there is each a video of the phenomenon, created by meteor smoke and water crystals high in the upper atmosphere.

Atmospheric Physicists

At http://notrickszone.com/2019/01/24/atmospheric-physicists-a-human-signat... ... Greek atmospheric physicists have cast doubt on climate change hysteria in a step by step dissection of the anthropogenic global warming hypothesis. There is a difference in what is hypothesized to occur atmospherically according to the AGW models and what has actually been observed from satellite measurements.

Gravity - Newton and Einstein

At https://phys.org/print456129421.html ... astronomers and physicists have revived a previously debunked theory of gravity, arguing that motion within dwarf galaxies would be slower if they were close to a massive galaxy. This is the Modified Newtonian Dynamics (or MOND as it is usually referred to) - which proved to be a controversial alternative to Einstein's General Relativity model. Modern attempts to keep general relativity alive have resorted to claiming dark matter plays a role - even if it cannot be detected.

Arrhenius

At https://chaamjamal.wordpress.com/2018/06/29/a-theory-of-ice-age-cycles/ ... an intriguing blog post by Chaam Jamal concerning some ideas by Gerald Marsh, a retired laboratory physicist who challenged mainstream views that ice age cycles were initiated by Milankovitch orbital cycles - and driven by the Arrhenius effect on carbon dioxide (co2). One can instantly see a problem - is the Arrhenius effect real (a hypothesis that has been subsumed into the mainstream narrative). The Arrhenius hypothesis goes back to 1896 (and before that we had Tyndal in 1861).

Validating Einstein

In Electric Universe circles we hear a lot about Einstein being wrong about this and that - and the failure of his theories (and the weakness of gravity and all that). At www.scientificamerican.com/article/einsteins-greatest-theory-validated-o... .... which is saying something quite opposite. Astrophysicist Tom Collett set out to disprove Einstein, he assures us, but instead found corroboration. He set up an experiment to test one aspect of Einstein's Theory of General Relativity (first published in 1915).

Misbehaving Neutrinos

Also sent in by Jovan - go to www.scientificamerican.com/article/evidence-builds-for-a-new-kind-of-neu... .... the article itself is available to read at the pre-porint arXiv server but the authors have presented it to an international conference in Heidelberg in Germany. We have muaon neutrinos and electron neutrinos but what are these new ones? However, a word of caution according to one souce. The researchers are not sure the flashes of light seen are really coming from neutrinos. It is possible some unknown process is producing an excess of photons that mimic the neutrino signal.

Standard Model of Particle Physics

At the link here the standard model of particle physics is discussed in an easy to understand manner - go to https://theconversation.com/the-standard-model-of-particle-physics-the-a... ... which begins, more than a quarter of Nobel Prizes in physics of the last century are direct inputs to or direct results of the Standard Model. We are told the standard model has predicted the results of experiment after experimentwhich includes the discovery of quarks and bosuns - as well as more famously, the Higgs Bosun.
