Thermospehre is a lie or its description is?
According to the wiki:
Thermospheric temperatures increase with altitude due to absorption of highly energetic solar radiation. Temperatures are highly dependent on solar activity, and can rise to 2,000 °C (3,630 °F). Radiation causes the atmosphere particles in this layer to become electrically charged (see ionosphere), enabling radio waves to bounce off and be received beyond the horizon. In the exosphere, beginning at 500 to 1,000 kilometres (310 to 620 mi) above the Earth's surface, the atmosphere turns into space.
The highly diluted gas in this layer can reach 2,500 °C (4,530 °F) during the day. Even though the temperature is so high, one would not feel warm in the thermosphere, because it is so near vacuum that there is not enough contact with the few atoms of gas to transfer much heat. A normal thermometer would be significantly below 0 °C (32 °F), because the energy lost by thermal radiation would exceed the energy acquired from the atmospheric gas by direct contact. In the anacoustic zone above 160 kilometres (99 mi), the density is so low that molecular interactions are too infrequent to permit the transmission of sound.
Summary:
Paragraph 1 states that the higher you go the hotter it is, due to solar radiation.
Paragraph 2 states that some gas up there can reach up to 2500C, but a normal thermometer would read below zero, because it is near vacuum and not enough contact between atoms of gas to transfer heat.
From what I gathered:
The only elements in the periodic table that can withstand 2500°C are carbon, niobium, molybdenum, tantalum, tungsten, rhenium, and osmium. Except for carbon, these metals are very, very heavy and are of course extremely conductive to heat and most are very ductile when heat treated meaning they bend and coil. Carbon even has the highest thermal conductivities of all known materials! So, if you want to cook someone very efficiently and quickly, there is nothing better than a space capsule made out of graphite.
Some issues:
What kind of thermometer were they using to measure the temperature up there then?
They said that solar radiation (infrared radiation from the sun) is the heat source. So the solar radiation will heat up these gas atoms. Now let us put a satellite they say that there will be no heat transfer from thsee atom gases because there are so few of them right? and if a normal thermometer is strapped at the side of the satellite it will read below zero right?
But will the solar radiation not heat up a satellite or the thermometer (they are just another form/collection of atoms)?
If a very powerful laser is pointed at these gas atoms surrounding a satellite/thermometer, will the surrounding gas atoms heat up while the satellite/thermometer not?
Are they saying the a gas atom some nanometers away from the satellite/thermometer would be 2500C while the satellite/thermometer would be below zero?
