OK, I understand now why they are thinking the sun is not efficient. You cleared it up. Thanks.
The question should be asked: Is there reason now or in the future for the sun's design? First, how much mass is being consumed every year through the fusion process? In order to have energy for billions of years, size is important. Temperatures must be at a certain level in order to continue the fusion process. Extra size and heat are necessary design to insure longevity.
Sure, if you want to supply energy using a star as a fusion reactor and if the laws of physics are as they currently are, and if you want to supply energy for billions of years to have a planet where liquid water can exist, then you should have a star of types type F, G, K.
But, considering that there is billions of such stars in our galaxy alone, is it not reasonable to say that if there is a purpose, they should ALL share the same purpose (they have the same structures and properties)? So any purpose the sun has should *at least* be shared with all other type G2 stars, right?
Now, given that many, if not most of those stars have no planets at all, the purpose cannot be to supply energy to planets, and so cannot be to support life. That says that any support for life is a side-effect even *if* there is a purpose.
Mankind has the technology now to get all our energy needs from the sun. God has placed the clean energy clearly in view just like birds flying. The choice is ours.
Well, your statement that we can currently supply all of our energy needs through solar power is simply false for a number of reasons.
Say you wanted to visit Saturn. When you get to Saturn, it sure is nice having light to see Saturn. How much extra energy is needed to supply ample lighting for exploration?
The total energy absorbed by all the planets and moons in our solar system is still a minuscule fraction of the total output of the sun. Well over 99.9999% of the energy from the sun just goes off into space, never to do anything else.
The sun supplies a gravity well for all the planets in order they do not wander off. A wandering Earth would not be a good design.
That depends on the goal, doesn't it? Why do you assume that life is a goal? And, as I pointed out before, any star similar to our sun would have the same gravity well and same energy output. Given all the shared properties, it looks like such stars, if they have a purpose, were mass produced and so have the same purpose. Since most do not have planets at all, that purpose cannot be simply to provide a gravity well for planets.
Mars is close and one day will be Tera-formed. It will need energy too. Large, Massive Jupiter protects the Earth through it's high gravity attracting things away from Earth. Design?
Why would you assume design? As opposed simply function?
How much are you missing?
Ebb and Flow of knowledge. If you were to build a world of life and a solar system of planets all with purpose, what would it include? It's all here. Look for purpose. It stares us all in the face.
Only if you assume purpose to begin with. Now ask (first* whether there is a purpose at all and how you cold tell.
So often, people want answers, yet the knowledge and wisdom is in the journey to Discover those answers.
Fool myself? It starts by studying all around and putting the puzzle together. If God exists, God can be found. God can be found!
Note that key word: **if**.
Do not discount an interaction with God. Sure, people can imagine things, however no one has the capability to duplicate an interaction with God.
How do you know that? How do you know such 'interaction' could not be duplicated artificially?
Hang onto your hat and prepare to peddle as fast as you can. Intelligence does exist far beyond that of mankind.
Proof?
Look at all around you. Intelligence exists all around at multiple levels and multiple views.
Proof? Objective evidence?
Free choice is an important part of God's system. One can choose to be blind. This will never be me for this hungry student thirsts for more and more knowledge. My journey continues.
So don't assume your conclusion before you start.
That's what I see. It's very clear!!
