What can I do to study string theory?

First try to learn advanced mathematics like Calculus, Linear Algebra, complex analysis etc along with advanced physics. Learn Quantum Mechanics and Relativity(you need to be adept in it as though it is the back of your hand). Then slowly watch intro videos on String theory, understand them thoroughly.

What are the limitations of string theory?

At present string theory has produced no testable experimental predictions. In the eyes of many scientists this renders string research unscientific: without experimental proof string theory becomes a mere intellectual exercise. We can only hope that future work will provide some progress on this front.

What does string theory propose?

String theory proposes that the fundamental constituents of the universe are one-dimensional “strings” rather than point-like particles. What we perceive as particles are actually vibrations in loops of string, each with its own characteristic frequency.

What is the most important subject to learn string theory?

Topology and group theory are also very important for string theory, although I do think it’s possible to have only a vague understanding of these subjects and still learn some basic string theory. Algebraic topology, algebraic geometry, and even category theory are often used in advanced string theory, but not necessary for grasping the basics.

How can string theorists verify their ideas?

Faced with accusations that their mathematical models cannot be tested, string theorists are retaliating with a host of thoughts on how to verify their ideas. These include looking for gravitational waves and scrutinising the results from particle accelerators. One of string theory’s most dramatic predictions is that we should find cosmic strings.

Is it possible to learn string theory without knowing quantum field theory?

Unfortunately quantum field theory itself has a lot of other physics prerequisites that need to be met before one can start learning it. And general relativity is the other big physics prereq for beginning string theory.

What is the superstring theory?

It encompasses quantum mechanics and gravity, and it is based on the idea that the fundamental building blocks of matter are not particles, but strings: objects which have some length, and which can vibrate in different ways. The first book you’ve chosen is Superstring Theory, Vols 1 and 2. This is pretty technical, isn’t it?
