Is the universe a hologram?

Well, this idea has resurfaced again, it would seem. Two Japanese physicists (Nature News, November 2013) claim an obscure bit of physics theory was the clearest evidence yet that our universe could be just one big projection (see www.arxiv.org/abs/1311.5607 and http://phys.org/print306152303.html). In string theory certain types of unverses might actually be holograms of real two dimensional universes.

The Expanding Universe theory ... without a squib to set it off

You have heard of the expanding earth theory - which gives Plate Tectonics a run for its money. Now we have the expanding universe theory - see http://phys.org/print305887548.html. It's all down to heat. It also doesn't require a squib - or Big Bang.

Liquid like plasma

The Large Hadron Collider at CERN in Switzerland is said to have found the Higgs boson, formed during collisions between bunches of protons travelling close to the speed of light. However, CERN scientists have also been smashing protons into ions of lead to generate clouds of quarks and gluons - the fundamental particles inside the protons and neutrons of the atomic nucleus. This has found that the emerging quark-gluon plasma is more liquid than expected. See http://phys.org/print305544262.html

Blue Light

At http://malagabay.wordpress.com/2013/12/02/cosmic-ray-blues-hadronic-shower/ .... Tim Cullen is surpassing himself this week as he sifts through a variety of sources on cosmic rays and hadronic showers, a process somewhat more complex than electromagnetic showers although both involve ionisation as they enter the atmosphere. Hadronic showers take longer to develop than electromagnetic showers - and they are also associated with Cherenkov Light, which is an intense shade of blue.

ECAT ... update

At http://phys.org/print304868667.html ... it seems we have a post by somebody not entirely convinced of cold fusion. However, it seems that ECAT portable cold fusion plants, as developed under Andrea Rossi, are on sale - orders are being taken. The acid test is therefore coming shortly - will they work? Within three months we shall know if the first buyers are happy - or unhappy with their new toys.

Picking at Bones

Consensus theories are often kept on board long after their sell by date. People become attached to them - a sort of comfort zone. Should that apply to science - does that apply to science?

Methane, methanogens, and ice cores (again).

At http://malagabay.wordpress.com/2013/11/22/methane-myopia-7-miles-mathis/ ... we have a link to somebody also criticising mainstream's treatment of methane - go to http://milesmathis.com/meth.pdf

Tim Cullen notes that within ice cores the methanogens have a plentiful supply of water from which they could liberate hydrogen. This suggests methanogens (in ice cores) reduces co2 levels while increasing the levels of CH4 and O2 which suggests the 'settled science' of extracting climate data and atmospheric gas levels from ice cores is basically, poppycock.

The problem on the Sun

One of physics biggest unsolved problems is described at http://phys.org/print303981706.html ... where two astrophysicists claim they have 'almost' solved why the Sun's corona is much hotter than the surface of the Sun. The corona is the source of the solar wind and solar flares are a potential problem to the inhabitants of the Earth, affecting power grids and telecommunications technology (such as satellites).

Oxygen, the atmosphere, and black smokers

This is the third link that is reminiscent of Malaga Bay (remember the black smokers on the ocean bottom) - see http://phys.org/print303899664.html ... a paper in Nature Geoscience by a team from the Norwegian Geological Survey claims oxygenation of the atmosphere and oceans came about two billion years ago. This also produced phosphorous - and phosphorus was the clue to the findings. Phosphorous is an important ingredient of life and all this popped out when the team were looking at rocks in Karelia (next door to Finland but in Russia) reputed to be two billion years of age.

Methane producing microbes

Malaga Bay also came to mind when I read the headline here too - see http://phys.org/print304016779.html ... microbiologists have found that methanogen microbes can reduce carbon dioxide to methane by a mechanism in which they make 'electrical connections' with other micro organisms, something not recognised in methanogens before. Bacteria anaerobically digest biomass to produce methane gas, an important piece of bio-energy. In nature these methanogens are active in bogs, swamps, and wetland zones, and their productivity is a source of angst to climate alarmists.
