It is for me surely the discovery of the year 2011!
Middle of December 2011, by reviewing some of my almost 20 years old figures, I have realized the fascinating idea that the tropopause is full of life. This upper boundary of the troposphere, where the atmospheric temperature reaches its coldest value of about -60°C, is a place full of life. OK, it is full of the most primitive life. It is the place where the universal Field of Light, with its characteristic value of -28.78°C, directly and continuously "produces" the smallest quanta of the living matter. These quanta, with dimensions between 4 and 20 nanometer, can be called nanoviroids. They are still no independently living systems, however they can be included ("eaten") into the core of viruses, and with them into the living cells of bacteria and algae, if they fall down as snow or rain to the Earth`s surface. As is also thinkable that the nanoviroids build the viruses by themselves.
The nanoviroids are just the missing link in my consideration of the Earth`s atmosphere, closing the gap between the so-called "optical window" and the "radio window" in the electromagnetic transparency of the atmosphere. The nanoviroids absorb and reflect the cosmic radiation (including the solar radiation) of the corresponding wavelength (between 4 and 20 nm) shielding the life below the tropopause. Otherwise this radiation would be dangerous to any higher form of life disintegrating it back to the nanoviroidal level.
One of the most urgent questions to be considered now: Which influence on this living shield have our airplains using just the tropopause for their long flights?
