You are continuing to return to the notion that science was at some point and time, philosophy. Science is in no way related to philosophy.
If you do not mind, let me suggest my reply to the thread "Can Everything be Reduced to Pure Physics" in Metaphysics and Epistemology. It outlines the general differences between science and philosophy.

Science is believed to be a means to give reason for once unexplainable phenomenon. It promises validity and preciseness. Some even state that science is an omnipotent method, which lives in the foreground of knowledge. It is beyond philosophy, as philosophy only lives in its unnoticed shadow, theorizing what science promises to eventually prove. The arisen conflict is not the dispute of science as a means of knowledge, but its claim to be an omnipotent source of this knowledge. Perhaps, it is the origin of scientific knowledge, but certainly not knowledge altogether. Since scientific knowledge only proves the most naïve and minor questions – which might at that certain moment, seem like enormously important ones --- while philosophy is a completely distinct method; a method which explains what science cannot.
The importance of philosophy should not be ignored. It is of course, greatly ignored in our civilization. Though, the most previous statement is ignored as well. It is difficult to communicate such messages to such narrow minded humans – who have devoted their entire life to one methodology of knowledge. These “automata” have been programmed by everything ranging from their education system to their media’s commandments. Once children who believe in epistemology as a synonym for scientific explanation, now are completely independent adults, who adapt to this perverse notion of complete scientific knowledge.
The universe is complex beyond our comprehension. The most intelligent of our civilization have been stuck in dazed state, where everything seems to be designed for something else in this infinite universe-puzzle, yet simultaneously, nothing seems to be related to anything else. The world appears strangely interconnected and disconnected at the same instant; scientific knowledge creates this perception. These people have failed to realize what is already in our nature. They have not understood, and therefore appreciated, human’s quest and hunger for knowledge; and not only scientific, but universal knowledge. Intellect which could explain the reason for Mars’s atmosphere, just as well as it could give meaning to our lives. Scientific, as well philosophical and theological knowledge is what we have been gifted with in our own human nature.
We can not use the same principle to explain the universe. Just as we could not live a life solely on one certain, specific principle. We need a combination of methods. One can not explain life using only the scientific method; nor only theology, or only philosophy. It is a combination of these which demonstrates the complex nature of the universe. Physics (or more generally, 'science',) is a simple tool, used to describe simple situations. It is productive – in fact, the most productive of anything known to humans. Yet philosophy allows us to produce knowledge beyond the scientific. We become aware of not only our external, physical surrounding and of specific occurrences and objects, but of our general meaning. The unimportant questions are answered by science. Science can not answer the most important questions because its method does not allow it. Science is pure physicality. Philosophy answers the questions which science fails to answers in a valid, clear, definite way. What philosophy does not answer, theology does. Each of these: science, philosophy, and theology, has its own way of answering questions. Its own 'method' if you will. You would not, for example, ask a physician to fix your car, because it is not his field of knowledge. You would ask a mechanic instead. Similarly, you would not ask a mechanic to prescribe you medicine. It is in no way, related to his method of work. Science is not sufficient enough for living a good life, and creating a good society. While humanity progresses, it realizes the questions which philosophy can answer, and those which science can. When that is realized, the question will be sufficiently answered by a specific method. Science investigates. Philosophy does not. Science is trapped inside the senses and human experience. Philosophy goes beyond the senses, and travels into the realms of reason and profound thought. Science can only investigate the phenomenal world. Everything beyond, is in fact, beyond its comprehension.
We should not look at philosophy as a shadow of physics or science. Philosophy is not the means of answering questions which science, in time, will answer anyway. We must come to realize they are two completely distinct methods of human intelligence. We do not philosophize and then use science to explain our philosophy. Science only attempts to answer what philosophy states. Similarly, philosophy sometimes attempts to answer what science can. "There is no dialogue between them".
Science is a means of producing. Philosophy does not produce anything at all. But knowledge is not only science. There is another use of knowledge. That use is philosophy. This philosophical knowledge directs us – directs us towards the good; towards our meaning. “The utility of science is production, and the utility of philosophy is direction.” Consequently, religion gives us the grace and faith to follow the directions with.

Well, a good understanding of how the Sun generates so much heat and light required patience considerably beyond one lifetime ... depending on how you understand the term 'science' (and I see from later in your post that you seem to have a very long term view), well over 5,000 years!
As i said earlier, scientific questions and philosophical ones do not relate in general terms.
If that theory took beyond a lifetime to produce, that only suggests that a philosophical theory of similar magnitute would take even longer.
You're joking, right? The origin and evolution of the universe? The nature of eclipses, stars and comets? The origins of the mammal Homo sap.? The causes of disease, weather, earthquakes? If I am not mistaken, most of these have come into the domain of science only in the last 500 years or so (and the origin of the universe, only the last 100 or so)
Therefore, although our perception of them has changed, their nature has remained the same.
And, in a few words, can you describe that invariant nature?
Natural Law.
:: Every object has a purpose. Everything/Anything is somehow fitting for something else. A woman and a male for example. Everything about the two seems to be interconnected. They seem to be complete when united. This is an example of the natural law. E.g. It is our purpose to unite with the opposite gender. Philosophy has a purpose. As well as science. We discover this purpose over time. This "purpose" has never changed. Only our understanding of it has.
