Re: Blue Sun Bristling (APOD 2009 November 4)
Now you made me hungry! Blue suns are too hot.
There used to be a lot of talk about using fusion for generating electricity. Containment seemed to be an overwhelming problem then. I haven't seen much about it for quite a while.
JET seems to be still working on it. http://en.wikipedia.org/wiki/Fusion_power

The energy source of our Sun is the nuclear fusion of hydrogen into helium deep within its core.

I like images like this becuase it gives texture to something I can't otherwise see with my own eyes. I get the same sensation about this image as I did when I first saw an scanning electron microscope image of a molecule of iron.

- Texture, n. [L. textura, fr. texere, textum, to weave: cf. F. texture.]
1. The act or art of weaving. [R.] Sir T. Browne.
2. That which woven; a woven fabric; a web. Milton.
Others, apart far in the grassy dale, Or
roughening waste, their humble texture weave. - Thomson.
3. The disposition or connection of threads, filaments, or other slender
bodies, interwoven; as, the texture of cloth or of a spider's web.
4. The disposition of the several parts of any body in connection with each other, or the manner in which the constituent parts are united; structure; as, the texture of earthy substances or minerals; the texture of a plant or a bone; the texture of paper; a loose or compact texture.

<<In cosmology, a texture is a type of topological defect in the structure of spacetime that forms when larger, more complicated symmetry groups are completely broken. They are not as localized as the other defects, and are unstable. No textures have been definitively confirmed as having been detected, but their existence is compatible with current theories and observations of the universe.
In late 2007 a cold spot in the cosmic microwave background detected by the Wilkinson Microwave Anisotropy Probe was interpreted as possibly being a sign of a texture lying in that direction.>>

In the UK, a lot of work is done on fusion at Culham, part of Britain's Atomic Energy Authority.orin stepanek wrote:Now you made me hungry! Blue suns are too hot.The energy source of our Sun is the nuclear fusion of hydrogen into helium deep within its core.

Might I point you to this https://lasers.llnl.gov/. This facility was build to investigate this possible source of power along with pure science in high energy physics. There is also the hugh facility in France http://public.web.cern.ch/public/.orin stepanek wrote:There used to be a lot of talk about using fusion for generating electricity.

Just after I posted this I saw on the Science channel the end of a video about 'making a sun on Earth' in reference to fusion power for generating electricity. I didn't see enough of it to see the progress made on the project. Back in the 50's; when I graduated, it was hoped for a replacement to fission power because it would create it's own fuel. http://www-ferp.ucsd.edu/LIB/MEETINGS/0 ... _brief.pdf I lost track of it until recently. Seems as there is still a lot of problems to be worked out.http://library.thinkquest.org/20331/typ ... blems.htmlDonAVP wrote:Might I point you to this https://lasers.llnl.gov/.

Poor Mainstream Science, they've really lost their way in thinking that hydrogen is being converted into helium deep within the Sun's core. Will the high priests of the BBT ever be able to unravel the religious mystery of how many neutrinos can dance on the head of a proton ? It's about that silly, Mainstream's assumptions of how our Sun operates.
H to He fusion only happens in the solar atmosphere where the temperature is high enough, and it only amounts to a small percentage of the total energy events our Sun experiences.
When we look 'down' into the eye of a sunspot, it's the coldest place we can measure on the Sun. It should be the hottest !, if the solar interior gets hotter the further down one goes.
Absolutely stunningly beautiful photo of our Sun !!!
And being in blue, for my eyes the details are easier to look at than being in red/orange.
Thanks again APOD for a wonderful visual experience !!

This bit of nonsense should be removed by a moderator before it confuses somebody coming to this forum to actually learn something about astronomy.kovil wrote:Poor Mainstream Science, they've really lost their way in thinking that hydrogen is being converted into helium deep within the Sun's core.
