calprime21 Posted March 23, 2012 Posted March 23, 2012 Is the sun hollow? Also this was said to me and was wondering if it was true. " Certain scientist believe that it receives power from "galactic currents" and that is how it is powered. The Sun is relatively cold inside, unlike popular belief from thousands of years."
Ophiolite Posted March 23, 2012 Posted March 23, 2012 There is no evidence at all that the sun is hollow. There is a star sized amount of evidence that it is not hollow. No actual scientist would believe that it got its power from 'galactic currents', whatever they are, because there is no evidence that this is the case. There is evidence that the sun obtains its energy from nuclear fusion deep in its interior, just as other stars do. We have an excellent understanding of how this occurs and this has been validated by a mountain of evidence from observation of the sun, experiments in accellerators, examination of the spectral character of other stars, analysis of supernovae, studies of the chemistry of the planets and comets and meteorites, and so on. Who ever told you this is either having a joke, or is very gullible. Hope that helps. 3
Phi for All Posted March 23, 2012 Posted March 23, 2012 Ophiolite beat me to it, and with a much better explanation. I rather suspected this was some kind of attempt to bring up the old Electric Universe crackpottery again. 1
swansont Posted March 23, 2012 Posted March 23, 2012 It's an eyebrow-raiser when "certain scientists" (or some scientists) are "cited". Funny how they are never named. 2

" Certain scientist believe that it receives power from "galactic currents" and that is how it is powered. The Sun is relatively cold inside, unlike popular belief from thousands of years." Interesting idea. If the sun would be powered by galactic currents, then the view of the sun as a accumulation of hydrogen which produce energy through fusion would drastically change. Our universe would look more like a living organism than a dead clockwork, where stars has a regenerative power, like biological cells which are powered also through electrical currents through the whole body.
ajb Posted May 7, 2012 Posted May 7, 2012 Are we confusing "hollow" with the different layers of structures in stars?
losthermit Posted September 30, 2012 Posted September 30, 2012 As I was reading about weak signal propagation relative to solar cycles, I came across a close up of the 22 June 2004 sunspot group: The grey areas around the sunspots seem to give the spots depth and a strange similarity to when bubbles have broken through your breakfast cream of wheat. Bubbles or crater-like formations on a spherical plasma body? What are the black regions made of? Is it shadow or the revealing depth of the shallow surface layer? Have 90-degree perspectives of sunspots relative to the surface of the Sun been conceived? If the black portions of sunspots were actual breaks in the surface layer of the Sun and what seems just below this layer is, apparently, not the same as the overall surface construct, is the Sun actually hallow and the surface finite in depth (very thin compared to its volume?) What would the interior be made of? Dark matter? What mathematical formulation could support such an armchair theory ?
John Cuthber Posted September 30, 2012 Posted September 30, 2012 A hollow shell would be unstable, it would collapse if anything hit it. We know that the sun gets hit by comets and such from time to time so the sun can not be hollow.
Ronald Hyde Posted September 30, 2012 Posted September 30, 2012 The Sun has several layers. Scientists have even developed a kind of 'solar seismology' purely by observation, and know something about the layers. The Wikipedia article on the Sun gives a very good description of this, it starts with the core and ends with the corona. http://en.wikipedia.org/wiki/Sun You can find several articles on the Wiki about the Sun.

Sunspots are just areas that are lower temperature than the surrounding Sun's surface. They are very bright and only appear dark by extreme filtering in telescopes.
Ophiolite Posted October 1, 2012 Posted October 1, 2012 Have 90-degree perspectives of sunspots relative to the surface of the Sun been conceived? Yes. http://www2.ucar.edu/news/sunspots-3d-multimedia-gallery
