What exactly will a TOE do for us as a society. How will we benefit from knowing all the four forces are united or that we know the origin of the universe. Yes this is all interesting and good information, but what benefit will we gain from it once we know?
As one of those members who run their own website to show how their work is progressing (these can be accessed from the members list )I would answer your question this way.
Firstly we cannot make real progress until we understand the fundamentals.
Secondly, there are a lot of people who misuse our lack of understanding to claim that they do understand the trueth in either or both scientific and religous terms. Such people are trying to maintain their position or priveleges or, worse still, use their claim to justify their right to control our lives.
It is remarkable that, as far as the fundamentals of creation or science are concerned; neither scientist nor religous leader can explain what these trueths are. Hawking, Fermi and other leading scientists together with religous leaders all claim that some things are beyond explanation.
My advise to you would be to remember the words of Isaac Newton
"It is to the glory of God that His works are done with the greatest simplicity"
Also note that Einstein commented that whenever faced with a number of possible solutions he always found the simplest solution to be the correct one.
By their own admissions, simplicity was the key to the success of both Newton and Einstein.
In my opinion nothing is beyond explanation, cut away the trade or professional language, reduce everything to the simplest possible term, in words as well as numbers; and you will understand the wonder of creation and the purpose of life. You may not be able to convey this understanding to others, for whom simplicity is a sign of ignorance; but you will have that peace of mind that comes from understanding your place in eternity.
Do not let simplicity of thought prevent you from enjoying the complexities of life, just remember that all complexity is developed from simple beginnings. Finding, understanding and using complexities is what life is all about.
Simplicity is your root, complexity is your future. It is always having something left to discover that will keep us going for all eternity; but remember, eternity does have an end, so make the most of it.
