Question

what is the universe made of? and does the string theory really apply to it?​

Answer 1

Answer:

Explanation:

The Universe is composed almost completely of dark energy, dark matter, and ordinary matter. Other contents are electromagnetic radiation (estimated to constitute from 0.005% to close to 0.01% of the total mass-energy of the Universe) and antimatter.

Thus string theory is a theory of quantum gravity. ... Since string theory incorporates all of the fundamental interactions, including gravity, many physicists hope that it will eventually fully describe our universe, making it a theory of everything. String theory is a potential “theory of everything”, uniting all matter and forces in a single theoretical framework, which describes the fundamental level of the universe in terms of vibrating strings rather than particles.
