Ahoj Mustangs, prva cast tvojho prispevku je v poriadku, je super, ze ta zaujima, ako sa na nejake konstatovanie prislo, zaroven z toho, co tu pises vyplyva, ze akosi apriori predpokladas, ze tie konstatovanie nevychadzaju z pozorovani a to bez toho, aby si si dal tu namahu a overil si to, to je teda dost nestastny pristup. odhad teploty slnka vychadza z aplikovania nasich vedomosti o plynoch gravitacii a vztahu tlaku a teploty a tieto vztahy pozname z pozorovania reality a ano nazyva sa to vedou, mozeme sa mylit, ale to sa da opat objasnit len vedeckou pracou, urcite to nefunguje tak, ze si niekto pred pc povie, ze je to tak alebo onak, bez toho aby sa vobec namahal nieco si o tom nastudovat. "The temperature of the surface of the Sun can be determined in various ways. We know how much energy we receive on Earth per unit time over a unit area facing the Sun. Then knowing the distance to the Sun, we can estimate total energy being emitted by the Sun. The total energy emitted per unit time per unit area is related to temperature in a known way. This can be used to find the Surface temperature of the Sun. Sun is a gaseous sphere and it seems to be a stable object. Our existence tells us about the stability of the Sun. We think that gravity holds the Sun together. In that case the gas pressure must be enough to balance the gravitational force. We know the relation between gas pressure and temperature, this is then used to calculate the core temperature. This is the simplest method i know of, other methods take into account some other effects as well but answers don't change much. "
