The theory converge to a single point of origin. Energy spark off the moment big bang happen. The pre-big bang theory is still under development. Time to time, there are new discovery that challenge or support the theory. I try not to direct readers to any single theory, as the discussion is about energy. That is another huge debatable topic....

Main stream science is what govern our day-to-day physics, hypothetical theory like string theory is way beyond my head I'm more of an applied science (yea, type 1).

Theory is fine, but to explain it in physics (mathematically speaking) is very subjective. New discovery on a previously assumed parameter could easily change half of the results. I'm not that good at drawing fast conclusion unless it is really convincing. It all boils down to assumptions drawn during writing. Certain assumptions are rather fictional, not until it was proven.

Like the dude who suggest that the earth is hollow, base on the assumption off aurora effect, and non-creditable writings..... well

If you want to know something about string theory and the practice of science, read this book

The trouble with physics by lee smolin

It is one of the best science books I read in years.

i've heard of the book's name in my book too.
is it available in any bookstore?
or do I have to order from amazon lol
