Step 1 · Read the article

Open the article and read it at the level above. Then answer the questions below in your own words.

https://smallwhale.org/articles/string-theory

Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the central mechanism?Different vibrational modes of strings correspond to different elementary particles and forces
2. What is the related theories?Superstring theory (bosonic and fermionic strings), M-theory (11 dimensions), AdS/CFT correspondence
3. What are the tiny strings that make up everything?In string theory, the smallest pieces of matter are not points but one‑dimensional wiggling strings that vibrate like tiny musical notes.
4. Why are the strings so small?The strings are about the size of the Planck length, roughly 10^-35 meters, which is far smaller than anything we can see.

Planck Length: The smallest theoretical measurable length, approximately 1.6 x 10^-35 meters, fundamental to string theory.
Quantum Field Theory (QFT): A theoretical framework that combines quantum mechanics, special relativity, and classical field theory.
Graviton: A hypothetical elementary particle that mediates the force of gravitation in quantum field theory.
