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

In summary, strings are one dimensional objects that make up every particle known to us. This means that there are no second or third dimensions, only the illusion of such dimensions due to the spinning motion of the strings as they move through space. The first dimension is any straight direction of travel, while a diversion from that direction creates a second dimension and a diversion from that plane creates the third dimension. The concept of planes does not exist in space, but is used to represent the three perpendicular space dimensions and the flow of time. The String theory attempts to explain the universe through resonances in the strings, and further reading is recommended for a better understanding of these concepts.

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.

FAQ: Are Strings the Key to Understanding the Dimensions of Our Universe?

What is the theory of Strings and Dimensions?

The theory of Strings and Dimensions is a mathematical and theoretical framework that attempts to reconcile the theories of quantum mechanics and general relativity. It suggests that the fundamental building blocks of the universe are tiny, vibrating strings that exist in multiple dimensions beyond our traditional 3 dimensions of length, width, and height.

How many dimensions does the theory propose?

The theory of Strings and Dimensions suggests that there are 10 dimensions in total - 3 spatial dimensions (length, width, and height), 1 dimension of time, and 6 additional hidden dimensions that are not directly observable to us.

What is the role of strings in this theory?

Strings are proposed as the fundamental building blocks of the universe in this theory. These tiny, vibrating strings are thought to be the source of all matter and energy in our universe.

How does this theory relate to other theories of physics?

The theory of Strings and Dimensions attempts to unify and reconcile the theories of quantum mechanics and general relativity. It provides a framework for understanding the behavior of particles on a quantum level while also accounting for the effects of gravity on a large scale.

Is there any evidence to support the theory of Strings and Dimensions?

Currently, there is no direct evidence to support the theory of Strings and Dimensions. However, many scientists believe that it has the potential to explain several unanswered questions in physics, such as the nature of dark matter and the unification of the fundamental forces of nature. Research and experimentation in this field are ongoing.
