The sun has many characteristics that are precisely fine tuned to support life on earth, but according to many evolutionists that is nothing to make a fuss over. Many insist our sun is nothing special.
The famous astronomer Carl Dagan once said, “Where are we? Who are we? We find that we live on an insignificant planet of a humdrum star lost in a galaxy tucked away in some forgotten corner of a universe in which there are far more galaxies than people.”
Is our sun ordinary? Not at all. Our sun is very unusual. It’s brighter than about 85% of all stars and has more mass than about 90%. In fact we should be very thankful that our sun is not an average star. Here’s why. About 75% of all stars are red dwarfs. These emit about 5% of the light output of our sun. If the earth revolved around one of these our planet would be extremely hostile to life. To be warm enough the earth would have to orbit extremely close to the star. That would create a tidal lock where the same side of the earth would always face the star. Photosynthesis would be impossible on the earth’s night side and possibly the day side as well because of the reddish light. So there would be no plant life, no food and no oxygen for us. Even worse than that, red dwarfs are unstable and they flare frequently. That would sterilise the earth if we were unlucky enough to closely orbit such a star.
So 75% of all stars are unsuitable for us. Of the remaining 25% many of them are also unsuitable - they’re too unstable or they emit too much radiation for life to be possible nearby. Even among massive stars the sun is unusual and even among class g stars such as our sun, more than half of them are in binary or multiple systems. These systems make it much more difficult for there to be a stable climate on any planet that revolves around them. Many of them would not be able to keep any planets in stable orbits. The more we examine the universe, the more unusual our sun appears. For years astromoners have been looking for solar twins - stars with characteristics similar to our sun.
Despite examining thousands of stars astromoners have discovered only a handful of candidates for twins and even these these few candidates still have significant differences from our sun. So we see that the sun is not average at all - it’s very special.
I just thought that you might find that interesting.
