Planck's constant has to do with energy, 6.626 X 10^-34 Joule-second, but you probably mean Planck's length 10^-33 centimeters.
And the answer is yes. The strings would be about that size. I was not sure, so I looked it up on the Internet. Plus I do believe that I have read that before in one of my books on string theory.
Superstring theory is a theoretical framework in physics that attempts to unify all the fundamental forces of nature. It proposes that the fundamental building blocks of the universe are not particles, but tiny vibrating strings.
Strings in Superstring theory are not made of anything physical. They are fundamental entities that do not have any substructure, meaning they cannot be broken down into smaller components.
Superstring theory requires a total of 10 dimensions to work mathematically. This includes the three dimensions of space that we are familiar with, as well as an additional seven dimensions that are compactified, or curled up, and therefore not directly observable.
Superstring theory is a specific version of string theory that incorporates supersymmetry, a theoretical concept that proposes a symmetry between particles with different spin. Other string theories may not include supersymmetry and can have different numbers of dimensions.
Currently, there is no direct experimental evidence for Superstring theory. However, it is still a popular theory among physicists because it has the potential to unify all the fundamental forces of nature and solve some of the biggest mysteries in physics, such as the nature of dark matter and the origin of the universe.
