A scientist in 1899 claimed the diameter is only 32 miles, some of his points made are very interesting.
''The sun is always somewhere between the tropics of Cancer and Capricorn, a distance admitted to be less than 3,000 miles; how then can the sun if it be so many thousand miles in diameter, squeece itself into a space of about 3,000 miles only...can a camel ride on a mouse, or a whale rush down the throat of a herring?
What is the diameter of the sun?
32 miles. If the navigator neglects to apply the sun's semi-diameter to his observation at sea, he is 16 nautical miles (nearly) in calculating the position his ship is in. A minute of arc on the sextant represents a nautical mile, and if the semi-diameter be 16 miles, the diameter is of course 32 miles. And as measured by the sextant, the sun's diameter is 32 minutes of arc, that is 32 nautical miles in diameter. If ever dispoof is attempted, it will be a literary curiosity, well worth framing.''
[later in the same thread]
I asked how you know the distance to the sun. You are claiming it's not an estimate but that you know the precise figure. So have you traveled to the sun and back? My point was to clarify the distinction between fact and estimates (guesses).
I'm open minded and read different theories. Unless you go up into space yourself there is no way of proving the exact size of the sun or location of celestial objects. It appears you base all your faith in what NASA etc tell you without ever questioning anything. I thought atheists were meant to be 'skeptics'?
