Are there string theories based on unidirectional paths or strings?
I ask because the polysigned numbers have some strong unidirectional
qualities.
In a lattice environment loops are the only way to return to a source
point.
These loops are inherently unidirectional:

The polysigned family naturally supports spacetime.
They do not support an upper limit on higher dimensions.

posted. The closest topic in string theory to Tim's comments are oriented
vs. unoriented strings. Both of them exist in various types of theories.
The fact that Tim does not see, using his simple analogies, why there
should exist constraints on the number of dimensions does not mean that
such a constraint does not exist. Indeed, we can see such constraints
if we look more carefully than Tim. LM]

Dear Tim,

Thank you for your question about string theories based on unidirectional paths or strings. I can tell you that there are indeed string theories that incorporate unidirectional properties.

One example is the concept of oriented vs. unoriented strings. In some string theories, the strings have a preferred direction of motion, while in others, they can move in either direction. This concept is similar to your idea of unidirectional paths.

Another example is the concept of supersymmetry, where particles are paired with their superpartners. In this case, the supersymmetric partners can only move in one direction, while the particles themselves can move in both directions. This is another way in which unidirectional properties are incorporated into string theories.

However, it is important to note that these unidirectional properties are not the only defining characteristics of string theories. Theories must also be consistent with other fundamental principles, such as special relativity and quantum mechanics.

In regards to your comments on polysigned numbers and loops in a lattice environment, they may have some interesting connections to string theory, but it is not clear how they would fit into the larger framework of the theory. As the moderator noted, analogies and simple observations are not always enough to fully understand the complexities of string theory.

In conclusion, there are indeed string theories that incorporate unidirectional properties, but they are just one aspect of the larger framework of the theory. I hope this helps to answer your question.

Thank you for your question, Tim. There are indeed string theories based on unidirectional paths or strings. In string theory, a string is a one-dimensional object that can move in any direction in spacetime. This means that it can travel in a unidirectional path, as you mentioned.

One example of a string theory that involves unidirectional strings is the bosonic string theory, which was the first string theory proposed in the 1960s. In this theory, the strings vibrate in a closed loop and can travel in any direction in spacetime.

Another example is the heterotic string theory, which combines elements of both bosonic and fermionic strings. In this theory, the strings can also travel in any direction in spacetime.

In terms of the polysigned numbers and lattice environment that you mentioned, these concepts are not directly related to string theory. However, string theory does have connections to higher dimensional spaces. In some versions of string theory, the number of dimensions is constrained to be 10 or 11, but there are also theories that allow for higher dimensions.

Overall, string theory is a complex and constantly evolving field, so there may be other theories that incorporate unidirectional strings or paths in different ways. I hope this helps to answer your question.
