Who was first to ask when our sun might exhaust itself?
by

1 Answer

Answer :

Another one of THOSE questions based on an absence of basic understanding. Nothing could be more vague than the term “modern scientific understanding”. Considering that the composition and functioning of the sun has been understood for less than a hundred years, Newton is out of the picture. The pieces to the puzzle were parsed and assembled back in the 1920s & 30s. Newton could approximate the mass of the sun, but its composition had to await advancement in spectography. So you have the fuel and quantity of fuel, but it’s useless until you can explain the rate at which the fuel is “burned” requiring an explanation as to HOW the fuel is burned. So when was the concept of nuclear fusion established?
