Talha Mumtaz's Key Ideas from The God Equation
by Michio Kaku

String theory suggests that the sub-atomic particles do not exist in points of space but are instead strings vibrating at different frequencies. The difference between different particles is that they may be vibrating on different frequencies. The theory proposes that one way these strings may be vibrating at different frequencies is due to sub-atomic particles called "Gravitons" where a Graviton mediates the gravitational force of interaction. String theory unifies Einstein's theory of gravity and particle physic, however, there is one problem, "String theory is purely theoretical..."

String theory suggests intriguing things about the nature of our universe. It suggests multi-verse. According to the string theory, when one component of universe change, it splits into multiplr versions with other options happening in the parallel universes. String theory also suggests that there may be 10 or 11 dimensions. However, as human mind cannot understand beyond the 4th dimension, the remaining dimensions are understood only through mathematics.

A theory of everything will surely give more sense to questions about the universe, the creation and how certain aspects of it works such as black holes, but it wouldn't revolutionize any technology per say. It will more like understanding a philosophy book compared to an expert textbook that may help you with your job or business. However, if you have always contemplated philosophical questions about the universe, black holes and other parts of the cosmos, the String Theory might help you when it becomes widely accepted
