NASAs Space Engine Tested

Spaceflight is difficult. Blasting heavy cargoes and spacecraft to respectable speeds over interplanetary distances requires so much propellant to sent rockets to far away places - unless you have an engine that can generate thrust without fuel. Scientists at NASA have been building and testing the EmDrive - which is said to produce thrust simply by bouncing microwaves around inside a closed cone shaped cavity. Sounds wonderful. No fuel is required.

Landscape Evolution

Scientists have struggled with a lingering question in geology. Why do the structures and elevations of some mountains continue to evolve long after the tectonic activity that formed them have ceased - see https://phys.org/print446805209.html ... and modelling has come to the rescue (or sort of). Sean Gallen from Colorado State University combined modelling with field research in a quite clever way to record the ebb and flow of activity in mountains in two national parks in the US. Activity clearly continued even after it was tectonically quiet.

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.

Flares on an inactive Sun

This is a cracker NASA images of massive flares unleashed by the Sun. There is currently a lack of sunspots but the Sun is highly active at the moment - via coronal holes. Go to www.dailymail.co.uk/sciencetech/article-5784685/NASA-spacecraft-spots-ma... ... and we are told that while the Sun can influence atsmospheric activities and the climate on Earth only certain wavelengths of radiation are able to make it to the surface to actually heat it up.

Uluru

The geology of Ayers Rock is interesting - see for example www.ayersrockresort.com.au/uluru-and-kata-tjuta/ ... and https://en.wikipedia.org/wiki/Uluru ... but to get some really good pictures by a geologist go to https://earthly-musings.blogspot.com/2015/11/ayers-rock-uluru-and-olga-m... ... which has some fabulous views. This site also has a whole range of geological expeditions by the author and his friends, also with many pictures.

Peering Under the Ice and Assessing the Reef

Ice penetrating radar data in central Antartica has revealed valleys and mountains near the South Pole - see https://phys.org/print446450328.html .... and it seems the mountains prevent ice flowing from the main ice sheet towards the West Antarctic peninsular (and the sea).

Mantle Rocks

At https://phys.org/print446447917.html ... first seismic evidence for mantle exhumation at an ultra lsow spreading centre. Note the words ultra slow - which means barely negligible (or as we later find out, 2cm a year). The area referred to is the Canyon Trough off Grand Cayman island in the Caribbean. Exhumation is a reference to the regurgitation of mantle crust - a major plank of mainstream Plate Tectonics. Through gaps at plate boundaries material from the Earth's interior is thought to emerge, forming new sea floor.

A Tale of Two Stratospheres

At http://spaceweather.com (clink link to 24th May 2018) we have a tale of two stratospheres. Lunar eclipses are brief but they allow scientists to see the upper atmosphere clearly. At the Global Monitoring annual conference in Boulder, Colorado, two new results were announed after analysis of two decades of lunar eclipse monitoring. The stratsophere is as clear as it has been for decades - there are very few aerosols up there. This is important, we are informed, as it is the stratosphere that allows sunlight in to warm the Earth at the surface.

Brian J Ford

Sent in by Robert - an article by Brian J Ford in the magazine Spaceflight from way back in the 1960s when it cost just 4 shillings a copy - go to http://brianjford.com/wbib65.htm .... and remember the article pre-dated the EU theory or anything by mainstream on plasma. Ford foresaw the craters on the moon as having an electrical origin - but invoked static electricity. He also said there were two outstanding features which cannot be accounted for by meteorites or volcanic activity, namely the occurrence of a central peak in many of the craters (but not all of them).

Valles Marineris

Valles Marineris on Mars (see image below sent in by Michael) is 2500 miles long yet it is claimed it was carved out by water - but appears to be a straight line, or nearly so, along a good deal of its length. The Grand Canyon on Earth has a river running through it - but the canyon is 10 miles wide and the river flows which way it wants, back and forth. Electric Universe enthusiasts think both have an electric origin rather than water flow.
