Undergrad Are Strings the Key to Understanding the Dimensions of Our Universe?

Click For Summary
Strings are one-dimensional objects that form the basis of all known particles, suggesting a fundamental simplicity to the universe's structure. While strings themselves are one-dimensional, they can move through three-dimensional space, leading to the perception of three dimensions. String theory requires multiple dimensions, with 10 or 11 being optimal for a comprehensive description, a reduction from the original 23 dimensions needed. The discussion highlights the relationship between space and time, suggesting that the universe can be represented as resonances in strings. Understanding these concepts may require further study in geometry and theoretical physics.

If strings are one dimensional objects and they make up every particle that we know of then there is no second or third dimension. There are only one dimensional objects that seem like they are three dimensional objects because they spin as they move through space.

Uh ... you may want to rethink that.
 
The strings themselves are one dimensional but, as you point out, they can move through 3 dimensional space.
 
Or, you can claim you are using the worldsheet formulation instead of the space-time formulation.
 
10 space dimensions, (so I gather) are needed anyway to describe a string theory, and 11 is better.
that's progress from the first string theories which needed 23 dimensions though.
 
So, basically, the first dimension is any straight direction of travel and a diversion from that direction becomes a second dimension and any diversion from that plane becomes the third dimension.

There are no planes in space.
 
Graphically we represent the space dimensions as 3 planes perpendicular to each other. Time flows through those three, and the space-time is a geometrical system(one can say) which is woven out of 2 threads:
1.That of space
2.That of time
If you want to drag the String theory in this, then it is a way of representing the whole of the universe in the form of "resonances" in the strings.
 
Dook and shihab-kol, how old are you? It seems you are interested in geometry but you had not time yet to read the fundamentals. Depending of the age and level, people in the group could recommend some reading, aiming to formalize your worries.
