Electromagnetism news

comets, asteroids, and the solar wind

Comet Pan-STARRS is still out there. It flared up in May and has since gone rather quiet - see latest update http://phys.org/print323672928.html ... so we have something else in August, when it is due to go round the Sun, that might prove interesting from an EU point of view. Mind you, Thunderbolts are getting excited already as they have posted us details of a new model developed by NASA with a view in mind of protecting astronauts - visiting asteroids.

Palaeolithic Plasma Images

Rens Van Der Sluijs has two posts at Thunderbolts this week. At www.thunderbolts.info/wp/2014/06/19/plasma-in-the-ice-age/ ... he refers to two engraved pendants fashioned out of reindeer bone which were discovered at a prehistoric site in France. The Magdalenian culture people followed and lived off reindeer herds much like the Lapps of northern Scandinavia in the modern world.

Electromagnetism and the Earth

Go to http://malagabay.wordpress.com/2014/06/13/the-carnegie-curve/ ... it seems scientists were looking at electricity in the atmosphere and on the Earth a hundred years ago - and an electric field between negative Earth and the net positive charge in the air. Experiments showed the intensity of the electric field is greater in the middle of the day than it is at night or in the morning - but conversely, is greater during the winter than it is in the summer.

Magnetic pulses

Very low frequency magnetic pulses have been observed in the run-up to earthquakes since the 1960s. Now, geophysicists claim they have discovered how rocks produce magnetic pulses - go to https://medium.com/the-physics-arxiv-blog/geophysicists-reveal-how-earth... ... the new model, it is hoped, will target regions of the crust at immanent risk. However, it is acknowledged it is not entirely certain if rocks produce magnetic pulses when there is no earthquake. It is a developing theory.

Magnetic fields and black holes

This story is at http://phys.org/print321105310.html ... a new study of supermassive black holes has found magnetic fields play a prominent role in proceedings. This was actually predicted and amounts to a confirmation of theory. It goes on to say that in the dozens of black holes so far surveyed (what are thought to be black holes to be more correct) the magnetic field strength matched the force produced by the black hole gravitational pull.

Miles Mathis on Gerald Pollack

At http://malagabay.wordpress.com/2014/04/20/miles-mathis-the-fourth-phase-... ... was provoked by Geral Pollack's book of the same name. The latter has produced in its wake a very hostile reception in some quarters of mainstream opinion but Mathis comes down on the side of Pollack after reading his tome. He points out that if you put the phrase, 'Gerald Pollack Quack' into your search engine you get pages of negative response.

Expanding Universe updatre

Thunderbolts have made their response to the claim that evidence has been found of an expanding universe - B mode polarisation (thought to be evidence of gravitational waves) - see www.thunderbolts.info/wp/2014/03/25/guths-goof/

At the Thunderbolts forum there is a general discussion and it is suggested that what has been seen is a slight shimmering of polarised light from a plasma discharge. Another poster said they might have been looking at light from magnetic fields.

Solar flares and magnetic loops

An international team led by University of Cambridge researchers has show how entangled magnetic field lines looping from the Sun's surface slop around each other and lead to an eruption of energy into space - go to http://phys.org/print315136097.html. The paper, published in The Astrophysical Journal, claims the mechanism has only been seen, as yet, in an X Class flare - but is probably also the case with other kinds of flare activity.

Big Coup

Guess who is speaking at the Electric Universe conference - Piers Corbyn. That should make it a bit exciting - I wonder what he will make of it all. Mind you, he must have researched EU before agreeing to speak, and some of his ideas do appear to correspond - but an electric Sun?

Many Moons Ago, Big Chill

This is not a reference to the Big Chill in the winter of 2013/4 but to a period of very cold weather that is recorded in the myths of different people around the world. Whether the big chill occurred contemporary in all those different places is another question, or whether it was cold in one place at one time and in another place at another time is an unknown. Anyway, Rens Van Der Sluijs can be read at www.thunderbolts.info/wp/2014/03/11/muddy-memories-2/ ... looks at different accounts by people from around the world.
