FE sun model cannot be correct
« on: June 27, 2018, 01:45:10 AM »
According to https://wiki.tfes.org/Sun" : The sun is a rotating sphere. It has a diameter of 32 miles and is located approximately 3000 miles above the surface of the earth."

But we know more about the sun namely that its surface temperature is about ten thousand degree Fahrenheit (yeah, no typing error, 10,000 is the number).

Of course, nobody went up there with a thermometer – it would melt and then evaporate like anything else at such high temperatures. So, how do we know ?

Well, it goes back to the 1800 when physicists realized that everything, including you and I, emits electromagnetic energy the amount of which (per unit time and surface area) depends on the material of its surface and its temperature. Many people make use of this using all kinds of night-vision goggles and cameras. Just google for “night vision” and “thermal imaging” or infrared radiation. Our eyes cannot see this electromagnetic radiation but snakes, for example, have sensors to pick up on that radiation to hunt down mammals which have a slightly higher temperature than the surrounding.
At higher temperatures materials can be seen to assume a dark-red color like the coils of an electric range, your toaster, or electric bathroom heater.  Those of us who have worked – or still work – in an steel foundry know that the color of the molten iron is a unique indication of its temperature, the whiter  the higher the temperature. No need to dip a thermometer into the liquid iron. Engineers use the equations governing electromagnetic radiation when they design and build the boilers for power plants, jet engines and even car engines. So, we know a lot about elector-magnetic radiation and apply to everyday problems rather successfully.

Hence, looking at the light coming from our sun and analyzing its content ( ultra-violet , rain-bow colors , infra-red ) we can deduce the temperature of the sun – some 10000 deg Fahrenheit, give or take.

Well, so why is that important ?

Like liquids, gases have the property of filling the available space. In this case, surrounded by empty space, a 32 miles diameter gas ball would just vanish in front of our eyes. Poof … gone. Come to think of it, it wouldn’t even have formed in the first place.

Don't be so cocky. In the Round Earth Theory figuring out how the temperatures of the sun makes sense has been a problem for a long time.

For more than a half-century, astronomers have tried to figure out what causes the corona to be so hot.  It is one of the most vexing problems in astrophysics.

Great article. Really drives home the fact that it's not about deciding what something should be and making things fit that, but trying to figure out how an observation could be explained when it comes to modern science. Not sure how you think this supports FE in any manner, or how it discredits RE to be honest. Seems to provide more credibility to the current scientific method and observations if anything imo.

I was NOT talking about the corona. That is 10 million times as thin as the Sun's surface and clocks in at 1 to 3 million degrees. Even harder to keep together without gravity. By the way, watching the total solar eclipse in 2017 with my own eyes was totally awesome. Next to me happen to be an amateur astronomer with his telescope with a simple tracking mechanism. Not once did he have to re-orient his telescope during the 2 hour eclipse; the sun was constantly in the center of view.
