Hello everyone,
This is my first post on this forum. Great to be here, after the pleasure of receiving the excellent "Universe Today" newsletter during the last few months.
In 1854 the eminent astronomer Sir William Herschel, who discovered the planet Uranus, suggested that the Sun may be no hotter than Earth's tropical regions! He believed the Sun to be much cooler than we think, not an intensely hot, flaming gas ball.
Since we know the planets are magnetic in nature, it is only right to assume that the governing body ruling those planets is also magnetic in nature. The Sun is like the magnetic "brain" or ganglion of our entire Solar System. It's forces are the directing intelligence of all the functions of our System. It is from this great central, nuclear body that the planets draw their magnetic energy so that they , too, may generate forces. When photographed in hydrogen light, the Sun displays its magnetic structure very well. Such a photograph shows a grainy effect very similar to that produced when iron filings are sprinkled in a magnetic field.
Scientists state that the Sun is a gigantic atomic furnace radiating a tremendous amount of heat to the satellite planets each second. The temperature at its surface is said to be thousands of degrees and the internal temperature is supposedly in the millions of degrees. However, it is unexplainable how super-heated gases can act magnetically. For, it is an elementary fact of physics that a substance loses its magnetism when heated! Since astronomers have definitely recorded magnetic effects upon the Sun, we have a direct conflict between the Sun's true nature and the suggested temperature. This conflict only indicates that the Sun is NOT the super-heated mass of gases that scientists think it is, but rather, a relatively cool body as the great astronomer Herschel said it was.
It is assumed that the Sun is radiating heat. People feel this heat when they stand in sunlight, so they say the Sun must be a burning mass radiating that heat. That is like saying a radio transmitter radiates sound waves because when we turn on our radios, we hear sound. But we know that such a transmitter radiates radio waves, and that these waves are turned into sound inside the radio! The same basic principle applies to energies received from the solar orb. Heat and light are effects of the positive rays of the Sun. Heat is felt on Earth because the Sun's positive rays intersect with its negative atmosphere and crust causing a friction or change in the quality of motion of the particles given off as heat radiation in consequence of this friction. The effect of the Sun's rays on the Earth's atmosphere is also responsible for the phenomenon of visible light which results from a different kind of motion of the particles. The Sun does not send us heat and light; rather, it sends only positive lines of force which interact with the negative crust and atmosphere of Earth to produce the phenomena of the electro-magnetic spectrum which includes heat and light.
If the Sun gives off intense heat, why is it much, much colder in the Earth's upper atmosphere (for example, 90 miles up) than it is close to the surface? Why does it get colder and colder the higher we fly above the Earth's crust? Shouldn't the exact reverse be true if the Sun is radiating great heat? Why is it dark as "pitch" 90 miles above the Earth if the Sun is radiating light?
The first astronauts were amazed to discover that the Sun appears a LOT LESS BRIGHTER in outer space than it does on Earth. Shouldn't it be brighter and hotter the closer we approach it? Why is outer space absolutely freezing and dark if great heat and light come from the Sun? Astronauts noted that outer space was darker than they expected, and stars and planets are not as bright as they appear to us on Earth! Therefore, it follows that energy rays come from the solar orb, NOT light itself.
Best wishes to you all, Russell

The Sun is radiating energy in many spectra. Infrared, visible light, ultraviolet, x-ray, radio, electromagnetic, etc. When that energy hits the Earth, it produces heat. We're not being warmed by the Sun, like in a warm room - in that situation, heat is transfered through some kind of medium, like air. The Sun's radiation hits the Earth and that's how things heat up.

That's why you can have spacecraft in space with solar panels generate electricity purely from the radiation from the Sun.

But, I can guarantee the temperature of the Sun isn't a balmy tropical temperature, it's thousands and even millions of degrees at various places.

Scientific experiments in which high temperatures are applied to magnets indicate that their magnetism is totally destroyed on reaching what's known as the Curie Temperature (310 degrees C.). Since the Sun's temperature is said to range from thousands to millions of degrees (well above 310 degrees, to put it mildly), this means that it could have absolutely no magnetism whatsoever, and therefore no rays in the electromagnetic spectrum could be radiated by the Sun to the solar system planets. The idea that our solar orb is a furnace of millions of degrees heat is in direct conflict with the fact that electromagnetic energy is emitted by it.

In the year 1543, a great comet came closer to the Sun than any previous comet had, and this was repeated by another comet in 1882. They actually entered the Sun's corona which supposedly has a temperature of one million degrees absolute. These comets traveled over 1 million kilometers through this blazing corona and emerged unscathed and with no change in velocity or direction. If the Sun is radiating heat, why weren't these comets instantly disintegrated upon entering a tremendous heat of one million absolute degrees? Surely nothing could survive such treatment!
Astronomers have told us that planet Mercury is devoid of life because it is only 36 million miles from the Sun. They also say that if Mercury were any closer, it would have turned into "nothingness" long ago. How then did the two comets survive without at least showing some effects of their journey through the Sun's corona? We must conclude that the answer is that the Sun does not radiate heat, as such. Therefore, it cannot be any kind of a super-hot body.

Sir William Herschel died in 1822 (see http://www.comp.glam.ac.uk/pages/staff/mre...reddy/herschel/ ). Herschel was one of the greatest visual observers in the history of astronomy, and I have great respect for his accomplishments, but that doesn't lend any credence to his crackpot hypothesis about the sun. Many other early scientists had misguided beliefs that were just as absurd. Newton was an occultist and alchemist, for instance (see http://www.cftech.com/BrainBank/OTHERREFER.../Newtonian.html ). Unfortunately, there is no shortage of crackpots and their "theories" in these supposedly more enlightened times as evidenced by this post and so many others that I see on the Internet.

No need to start calling everything outside mainstream "crackpot". Remember that every really new insight MUST have started as crackpot idea. Just read the positive points in the posts and if you spot real mistakes or you know a better explanation, just say so. Even the best theories are just that, theories. They can be refuted with the discovery of new facts. Arrogance has no place in science and we still have a lot to learn.

Positive points?

Pointless!

New theories come from hypotheses based on solid data, not from unfortunates with delusions of grandeur who have never cracked a physics text in their lives.

The temperature drops with altitude only to a certain point. In the troposphere(0-7km) air temperature drops by approx 2 degrees C for every 1,000 feet in alitude gain. Then when you reach the Tropopause the temp levels out. In the Stratosphere the temp is pretty constant and above that the temp actually increases with altitude up to the Exosphere.

Thanks,

Didn't know that the temperature gradient was discontinuous, is there information on why this is happening? Is there maybe another way of heating from outside in (as opposed to heating the surface and radiating heat outwards)?

"Heat" can only exist in matter, because all heat is is the movement of atoms, which of course is matter.

I apologise because I haven't had time to read all your comments, but there's a story breaking today that the Sun is cooling down... when I find a link to it, I'll post it...

The thermosphere is 1200 degrees C. Which is 90+ km high.

Well, if heated substances lose magnetism, the sun certainly cannot be holding the planets in orbit. Ulysses travelled near the sun and recorded its temperature and proved it to be high.

But the sun's internal temperature is just supposed to be in the millions. Maybe there are cool magnetic substances in there, and that may be holding planets in orbit and the temperature recorded is the surface temperature and not the internal temperature. But a question arises? Why isn't the inside getting heated?

Maybe there is another body holding the planets in orbit. But why has it not been discovered? Guess this is one question without an answer.

Just when I thought I have heard it all, a posts like these crawl out of the woodwork.
1. Magnetism is not what holds the planets together but gravity.
2. The sun develops vast magnetic fields as evidenced in the sunspots. These can even sometimes invert
3. The center of the earth has a very high temperature and is the source of the magnetic field which we all observe. Bodies without a very hot centre do not create magnetic fields.
4. There are countless reports of comets getting too close to the sun and being vaporized.
5. The sun is a very hot body otherwise we and everything around is will be frozen stiff.

I think this is a topic for "Against the Mainstream" and does not belong here
