Is the Sun really hot?

alternative science ^

[TheCrusader]

I just read that two Islamic scientists from Iran, Mohammed Abu and Ali Abbas are working on a rocket that will go to the sun and return with important information on solar heat. They couldn't develop a coating for the rocket that can withstand the sun's intense heat, so they decided to launch it at night, when the sun isn't shining.

Its pure tinfoil bs.

Regarding the "missing neutrino" data. They solved that. Mathematically they determined there are 3 types of neutrinos. Factoring that in, everything comes out correctly.

My head hurts. I'm still working on whether water is wet or not. But it could be true - I've seen a friend of mine drinking scotch on the rocks, and inside the swirling liquid there's this little solid cubical thingy...

An interesting hard physics hypothesis that explains some things currently not addressed by "standard physics".

I don't think so. It's my impression that the high temperature of the solar corona and the other "unexplained" things mentioned in the article are in fact now well understood.

The real tip-off that this is a crank is the mention of perturbations of Mercury's orbit. Mercury's orbit precesses in an anomalous way (as far as Newtonian mechanics goes) -- but this is precisely explained by general relativity, which has abundant experimental evidence. I say this is a tip-off that this is a crank because that's something cranks like to do: disprove Einstein. For the mathematically-inclined, a nice treatment of general relativity and the orbit of Mercury is given by Frank Morgan in his little book Riemannian Geometry: A Beginner's Guide.

As far as fusion and the Sun goes, decades of observations of supernovae and other stellar phenomena have provided a rather complete picture of stellar fusion processes. I would be willing to trust the physicists and astronomers on this one.

Says Boscoli, 'If this mass of gas . . . would begin to rotate upon itself, it would necessarily assume a progressively flatter ellipsoidal form as its rotational velocity increased. And . . the Ranque effect would begin to be exerted, therefore producing a cooling at the centre and a heating of the periphery of the ellipsoid.'


 

Reading that made my head hurt.

And now, Italian physicist Renzo Boscoli, has published details of a theory that is staggering: the theory that far from being hot underneath its atmosphere, the sun may, at its core, be a ball of ice in which not hot, but cold fusion reactions are taking place.

Astouding (not)...

Celebrated and uncelebrated scientists alike have said for years that the sun is cooling off...Eventually, the flame will burn out...So what's that??? Evolution going backwards???

I had to quit reading when I read "degrees Kelvin." That ruined it for me. From what I remember Kelvin is measured simply in Kelvin, not degrees Kelvin. See here - http://physics.nist.gov/cuu/Units/kelvin.html.

This explains all the people who get frostbite from lying out in the sun, all right

"the sun so hot, I froze to death...with my banjo on my knee"

When will America wake up to the threat of Solar Warming?

[embedded_rebel]

We need a GLOBAL TEST.

As is much of the science on our planet.

There are some problems with this view. For instance, when gases are compressed, as under gravity, they also heat up, and this makes them expand. As temperature increases, the outward force due to expansion will become greater than the force of gravity compressing the gas and the gas will simply dissipate in space again. How then could the condensing hydrogen cloud ever ignite spontaneously?

Come on. This is a joke.

[Iscool]

ouch!!! The sun ain't that hot!!!!!!

The real tip-off that this is a crank is the mention of perturbations of Mercury's orbit. Mercury's orbit precesses in an anomalous way (as far as Newtonian mechanics goes) -- but this is precisely explained by general relativity, which has abundant experimental evidence.

For me, the real tip-off was the following:

This experimental result appears to contradict the laws of thermodynamics and at present remains unexplained.

I would like to know which laws of thermodynamics are contradicted.

Whoa, Whoa, Whoa. Is the sun hot? this is getting to advanced for me. Is water whet, is ice frozen? Do I know everything or nothing? What's the point of getting into this stuff anyway? The sun keeps us warm and gives us light. That is all I know, and care.

HAHAHAHAHAHAHAAAAA!!!

Good one.

I've always been interested in - cosmology!!

"Regarding the "missing neutrino" data. They solved that. Mathematically they determined there are 3 types of neutrinos. Factoring that in, everything comes out correctly."

"Mathematical determination" itself is tinfoil-hattery--until verified by experiment.

"There are some problems with this view. For instance, when gases are compressed, as under gravity, they also heat up, and this makes them expand."

Please indulge me in a few nit-picks. When gases heat up, they TRY to expand. If they cannot, due to constraints, they get even hotter.

Temperature is a measurement of molecular velocity. The hotter it is, the faster it runs around, bouncing off of neighboring molecules. When the velocity of two colliding hydrogen molecules is high enough, they stick together. Voila! Fusion.

One thing that is not investigated enough is the grainy appearance of the outer surface of the Sun. It resembles the same texture as the top of clouds that form over the northern California coast in the summer, the result of vertical movement within the cloud layer. There must be a tremendous amount of radial movement within the volume of the Sun.
