Are sunspots dark matter?

Question

It seems that the sun is trying to fight against the dark matter again. Here is a saga of heroic proportions; the sun versus dark matter! See the Goliahs and Bohemoths fight the eternal struggle for supremacy! Why are we so unaware of this battle of the millenium? All other galaxies watching this wrestling match! At least we will have front row seats! Also, lets hope we are not entering the asteroid belt anytime soon. Would anyone let me know if we were headed into the asteroid belt? Also, do you think that the sun and planets have opposite elements that keep them neg/positively charged so that the planets do not fall into the sun by magnetic attraction principles (which should have happened years ago). And that the dark matter which is heavier than matter is the soup which makes up the space and keeps us afloat in the universe? Otherwise we would either a) fall into the sun or b)have no logical pattern of movement or position in the galaxy, i.e. we would be like Nubulas.

Answer 1

A sunspot is a region on the Sun's surface (photosphere) that is marked by a lower temperature than its surroundings and intense magnetic activity, which inhibits convection, forming areas of low surface temperature. Although they are blindingly bright, at temperatures of roughly 4000-4500 K, the contrast with the surrounding material at some 5700 K leaves them clearly visible as dark spots. If they were isolated from the surrounding photosphere they would be brighter than an electric arc. As of 2006, we are near a minimum (predicted for 2007) in the sunspot cycle [1].

Similar phenomenon observed on stars other than the Sun is commonly called a starspot.

In astrophysics, dark matter refers to matter that does not emit or reflect enough electromagnetic radiation (such as light, X-rays and so on) to be detected directly, but whose presence may be inferred from its gravitational effects on visible matter. Among the observed phenomena consistent with the existence of dark matter are the rotational speeds of galaxies and orbital velocities of galaxies in clusters, gravitational lensing of background objects by galaxy clusters such as the Bullet cluster, and the temperature distribution of hot gas in galaxies and clusters of galaxies. Dark matter also plays a central role in structure formation and Big Bang nucleosynthesis, and has measurable effects on the anisotropy of the cosmic microwave background. All these lines of evidence suggest that galaxies, clusters of galaxies, and the universe as a whole contain far more matter than is directly observable, indicating that the remainder is dark.

The composition of dark matter is unknown, but may include new elementary particles such as WIMPs and axions, ordinary and heavy neutrinos, dwarf stars and planets collectively called MACHOs, and clouds of nonluminous gas. Current evidence favors models in which the primary component of dark matter is new elementary particles, collectively called nonbaryonic dark matter.

The dark matter component has vastly more mass than the "visible" component of the universe. [1] At present, the density of ordinary baryons and radiation in the universe is estimated to be equivalent to about one hydrogen atom per cubic meter of space. Only about 4% of the total energy density in the universe (as inferred from gravitational effects) can be seen directly. About 22% is thought to be composed of dark matter. The remaining 74% is thought to consist of dark energy, an even stranger component, distributed diffusely in space. [2] Some hard-to-detect baryonic matter (see baryonic dark matter) makes a contribution to dark matter, but constitutes only a small portion. [3] [4] Determining the nature of this missing mass is one of the most important problems in modern cosmology and particle physics. It has been noted that dark matter and dark energy serve mainly as expressions of our ignorance, much as the marking of early maps with terra incognita. [2]

Answer 2

No, sunspots are not dark matter, they are merely cooler regions on the surface of an extremely hot gaseous surface. Sunspots are somehow linked to the cataclismic erruptions that occur on the surface of the sun from time to time recording the consumption of some exceedingly rich pocket of volitile gases and minerals. Those exploding pockets could be as large as South America, or the entire Pacific Ocean.

I am not sure what to make of the rest of your question. It seems that you wish to redesign interplanetary geophysics in a sentence or two. i do not think that is possible. The "soup" to which you refer as being outer space is a great deal different from soup. I suggest to you that it is an absence of soup, or anything else, that more clearly describes the vacuum of outer space.

Lastly, none of the objects or particles in space are merely hanging there in suspension like foam on water. All matter in space is moving. Some objects move in cordination with others. At the same time, driven by different forces, we have objects traveling in completely different directions. The speeds at which these various objects travel is mind boggling. For example: Did you realize that the surface of the Earth is spinning around at a calculated 1005 Miles Per Hour? Yet the meteors which we observe in the night sky can fly completely across the visable horizon in less than a fraction of a second. In the best case (Meteor travel direction = same direction as Earth rotation), that means that the meteors are moving at 20,000 to 30,000 miles per hour, or more. As a result, I would not stand around for long waiting for the stars, moons, and planets to fall out of the sky. You will turn to dust long before that happens.

Answer 3

No, they are just the cooler parts of the Sun. We won't head into the asteroid belt anytime soon and I don't think that the planets have negative elements because we are actually heading towards the sun. Dark matter has no known function whatsoever, but makes up about 90% of the mass in our universe.

Answer 4

sadly the sun is burning out,if you have noticed,it looks bigger in the sky,thats because its turning into a red giant and will gain 1000 times its mase over the next couple years and will absorb the earth,as far as dark matter,ya it looks dark

Answer 5

what was the reason for this question? can you explain?

Answer 6

no
