Questions:
If the heat of the Sun is streaming down to Earth, why is it that as we go up a mountain, or above the atmosphere..therefore CLOSER to the Sun it gets colder?
Why is it that sattelites and comets passing close to the SUn do not burn up?
If light is also coming from the SUN, why is it dark even in daylight 60 Ml above the Earth and pitch dark after 90ML s?
Scientists say that the Sun spins on its axes and its poles oscillates. Only bodies with hard crust and soft inner core spin on their axes. If this is true of the Sun, the million degree of "burning" would turn the hard core into gases..burn up the Sun
Scientists also say that what burns (helium, hydrogen etc ) on the surface on the Sun is plasma. Plasa is COLD, just as well as bodies with hard crust.
Between the atmosphere of the Sun and the Earth there is space. A FIRE created flame needs material particle to be carried away.. The rays of the Sun are invisible...
What I think is, that heat and light is the property of Earth and its elements especially oxygen. So it is not actual HEAT and light what comes from the SUN but "forces and rays which when "hit" the Earth ACTIVATES its elements which results in heat and light.
So the Sun is the secondary cause , the activator of the properties of the Earth namely heat and light.
The flames of the Sun are cold plasma flames.
Full Version: Is the Sun a cold body?
I don't know much about a "cold" sun, but the sun has to emit light. The human eye uses light to "see", so if no light came from the sun, we wouldn't be able to see it. Unless that light was reflected off of the sun, but that doesn't make much sense.
About why it's getting colder when we go up there, it has something to do with the earth's atmosphere.
Sun is hot.
The temperature of moon's surface during the day may reach 107°C, while it drops to -153°C during the night. It changes drastically because there's no atmosphere on the moon.
The distance to the sun may affect the temperature , but rising few thousand feet closer to the sun (by climbing a mountain for example) doesn't give big difference.
The satelite doesn't burn up while receive a direct contact with the sun light because the heat is not hot enough to burn it up (even the moon which is closer to the sun only reach 107 degree on the surface).
But to be honest I don't know the detail about why the atmosphere up there is much colder than on the surface.
The space's "sky" is dark because the light is scattered away into the deep space. On earth, the sky is blue and bright during the day because earth's atmosphere keeps the sun light trapped inside the atmosphere by reflecting and scatter the light into the earth.

http://en.wikipedia.org/wiki/Atmosphere
The temperature difference as you go up in the Earth's atmosphere has to do with lapse rate and also molecular distribution. The further you go up in the atmosphere, the thinner it gets which means that the air will spread out to cover a larger distance, thus becoming colder.
http://en.wikipedia.org/wiki/Vacuum
Also, the further you go out of the atmosphere towards space, the temperature decreases because the temp in a vacuum (space) is extremely low. -454 degrees Fahrenheit!

Questions:
If the heat of the Sun is streaming down to Earth, why is it that as we go up a mountain, or above the atmosphere..therefore CLOSER to the Sun it gets colder?
the atmosphere is thinner. The feeling of hot temperature is a combination of how fast the molecules vibrate and density. If you feel the air of a hot furnace with your hand, it will not burn but if you put your hand in hot water of the same temperature, it WILL burn. water is denser. Getting 10km closer makes no difference.
Why is it that sattelites and comets passing close to the SUn do not burn up?
Same reason, lack of molecules to vibrate
If light is also coming from the SUN, why is it dark even in daylight 60 Ml above the Earth and pitch dark after 90ML s?
It's because our atmosphere refracts some of the light of the Sun, therefore lighting up the sky. You can see stars if you go up 90miles because there is nothing to refract the light of the Sun.
Scientists say that the Sun spins on its axes and its poles oscillates. Only bodies with hard crust and soft inner core spin on their axes. If this is true of the Sun, the million degree of "burning" would turn the hard core into gases..burn up the Sun
The Sun is all gas. There is no 'hard crust' ... actually the deeper you go, the denser it is. The center is extremely hot and thru heat transmitting processes like convection, it warms up the outer layers of the Sun.
Scientists also say that what burns (helium, hydrogen etc ) on the surface on the Sun is plasma. Plasa is COLD, just as well as bodies with hard crust.
I always associated plasma with heat. Plasma is a state where the electrons have enough energy (needs heat) to break away from the attraction of the atom nucleus. Lighting bolts are plasma, and The Sun (at least the more inner parts) is fully ionized plasma.
Between the atmosphere of the Sun and the Earth there is space. A FIRE created flame needs material particle to be carried away.. The rays of the Sun are invisible...

It defies laws of physics saying that stars are cold. It's impossible. All normal stars' centers are millions of degrees of temperature in their cores so that the reactions that create light/energy could take place (it's called Nuclear Fusion).

During formation of suns and galaxies changes in pressure create temperature changes that may soar to super hot following thermodynamic laws, but in a steady state as in a mature sun, the atoms in a state of plasma are actually cool. Plasma is cool, not hot. The photonic effect of change of state from excited atoms to relaxed atoms in plasma causes the release of photons, which are the solar light we see. Currently science is not in technological conditions to prove this fact. Sun is formed by plasma of atoms of hydrogen, helium, and others. But the sun is hollow and the layer of gases is not deep enough as to produce the temperatures of millions of degrees produced by the weight of atoms compacting themselves and generating high temperatures by thermodynamic laws. (Pressure generates temperature).
The energy transfer is produced by waves of thermal radiation as in combustion or by electromagnetic waves ("cold") as in radiofrequency. The sun obviously would destroy a satellite that gets too close to its surface not because of the heat but because of the high radiation of waves (gamma, alpha, cosmic, ultraviolet, visible, IR rays, etc. ). A person should not put his/her hand in a plasma of gases not because it may burn but because the high radiation may destroy his/her hand. The interaction between the morphogenetic fields of the Earth and of any celestial body and also of the matter of animate and inanimate beings (that it is also formed by morphogenetic fields) and the solar radiations is responsible for the heat. Accurately speaking the sun is neither hot nor cold in its steady state since it is plasma and its radiations are neither cold nor hot. The temperature of this plasma is affected by thermodynamic laws. But comparatively speaking to the millions of degrees attributed to its surface it is actually cold, not freezing cold though.

What is actually taking place is that an enormous efflux of electric and magnetic power flows from the sun and sets in vibration whatever this electric power falls upon. It is just exactly as every electrician knows: if you pass an electric current through a length of wire filament you encounter a resistance, which makes the particles in the wire through which the electric current passes, and which possesses this high resisting power, to glow with heat. It is not the electricity which carries heat and deposits it there. Electricity is neither hot nor cold. It is the power of the electricity meeting this resistance, which throws the molecules and atoms of this resisting medium into intense vibration, more rapid than that of billions and quadrillions of vibrations in a human second, and therefore heats it. Electricity is not itself hot. Just so with the sun. The sun is neither hot nor cold as we understand heat and cold. It is an enormous body of force, forces, which include electricity and magnetism and consciousness and life and intelligence and other things.

The inner region of Earth’s magnetosphere contains a low-density mixture of hot and cold plasmas, which include the ring current, the plasmasphere, and the radiation belt.
http://www.physicsforums.com/showthread.php?t=59693
that cold plasma exists in the sun where it is virtually not even hot enough to burn you, yet it is still excited enough that it can erradicate bacteria, and create protection from radiation(because plasma tends to have a such a strong electromagnetic field)
It is any gas that is electrically charged or, like solar plasmas, has had it's electron's stripped off, leaving it's nulcei bare. So techniquely it does not have to be energetic (hot) to be a plasma.

The near-Earth space environment is not a perfect vacuum, but is filled with plasma formed when the sun's ultraviolet rays electrify the upper parts of the Earth's atmosphere. We know what the plasmasphere looks like by taking images of it from satellites positioned far above the Earth.. The effect of a space storm is to pull the plasma sunward on the dayside of the Earth. As a large volume of plasma is pulled sunward, it maintains its doughnut shape, following the magnetic field line geometry.

This process is called the ozone-oxygen cycle, and it converts UV light into heat, preventing it from reaching the surface of the Earth. Without the sun, the Earth wouldn't have an ozone layer -- but without the sun, the Earth also wouldn't need it.
But while the sun creates the ozone layer, the Earth itself creates its defense against the solar wind. Without the Earth's magnetic field, ionized particles from the solar wind could strip the planet's atmosphere away. This magnetic field comes from deep inside the Earth's core. Interactions between the inner and outer core create the magnetic field.

Looks pretty hot to me.
I this a serious thread? I mean the latest NASA probe they are sending to orbit the sun needs to resist 2k degrees temperature.
It is serious. There are a handful of people on this site that staunchly believe the sun is Cold. There was a thread on this in another sub-forum. Alternate History perhaps? It went on for several pages.
All the arguements used by Cold Sun followers are easily dispelled with high school physics. It is ignorance of science, physics and chemistry in particular, that lead to such speculations.
You only need to look at zitro1987's post to see that logic points to a Hot Sun.

It takes 6 minutes for the light fron the Sun to reach Earth.But I still don't undertsand how people can think that the Sun is cold :S!But I am 50/50 for the idea.It seems lilely but it's not how it works.

Welcome to the forum
Well, I think you can scratch that 50/50 idea (that is, if I understood you correctly). Unless we completely rewrite physics as we know it, the sun is hot - and very much so Cheers,
Badeskov
i might have misunderstood him, but does the person who started this thread think that the sun might be cold at it's core, but REALLY hot on it's surface for whatever reason... or does he think that the WHOLE thing is actually cold? at first i thought he meant just in CORE was cold, and since i know so little about the sun/chemistry/etc., i considered it and kept on reading... but then i got to the bottom of the thread and read everyone's responses, and now i'm not sure if he was asking if the Whole sun is cold... any idea?
the sun is the hottest body in our solar system, the reason why comets and satelites dont get any warmer the closer it gets to the sun is because the space around it is cold.
