Can All String Shapes Be Derived from a Figure 8 Configuration?

brane and string shapes ?

Hello, I am an uneducated savage so please bear with me and respond in laymans terms if possible so essentially I have 2 questions

I was wondering if all variations of string shapes could be made from sections of a figure 8 shaped string which co incidentally or not is an infinity symbol ?

closed loops, open loops, straight sections even X shapes can be made from a figure 8 shape

I'd like to imagine that each point in the above figure represents a dimension that the string vibrates across but it needs to pass thru the cross over point of time and 3 others to register as a physical object in our universe if not then it registers as an effect like gravity or light. Given that it can change shape it could disappear from our universe and back again by vibrating in and out of any number of points/dimensions.

secondly


If our universe is a bubble shaped brane are we on the inside surface or the outside surface ?

I would actuallly like to think we are in between the 2 surfaces of separate branes so for all intents and purposes it appears as though our universe is embedded in a bubble skin whose "leading edge/surface" is expanding at lightspeed faster than it's "trailing edge" giving the impression of inflation but all the while moving in a higher medium, only we can't tell as we are always looking from the inside out. So depending on which way we were looking things would be either moving towards us or away.

thanks in advance

Hello RK,

Thank you for your questions. I can certainly understand your curiosity about string shapes and branes. Let me try to address your questions in a simplified manner.

Firstly, the idea of string theory suggests that the fundamental building blocks of our universe are tiny strings, vibrating at different frequencies. These strings can take on different shapes, including the figure 8 shape you mentioned. However, it is not accurate to say that all string shapes can be made from a figure 8 shape. There are many different ways that strings can vibrate and interact, leading to a variety of shapes.

In terms of dimensions, string theory proposes that there are more than the three dimensions we are familiar with. These extra dimensions are curled up and not directly observable in our everyday lives. The vibrating strings move through these extra dimensions, which can affect their behavior and interactions.

As for your second question, the concept of branes (short for membranes) is a part of string theory that suggests our universe may exist on a membrane or surface. This membrane could be bubble-shaped, as you mentioned. However, it is not clear whether we are on the inside or outside surface of this membrane. Some theories propose that there could be multiple branes, and our universe could be sandwiched between them.

Overall, string theory and brane theory are still highly theoretical and not yet proven by scientific evidence. While they offer intriguing possibilities, there is still much research and experimentation needed to fully understand these concepts. I hope this helps to answer your questions.

Hello RK,

No worries, I will try my best to explain in simpler terms. Brane and string theory are complex concepts in physics, so it's completely understandable to have questions and need clarification.

To answer your first question, yes, all variations of string shapes can be made from sections of a figure 8 shaped string. In string theory, particles (such as electrons and quarks) are not thought of as tiny dots, but rather as tiny loops of string. These strings can vibrate in different ways, giving rise to different types of particles. So, in a sense, you could think of the figure 8 shape as representing the possible vibrations of a string that can create different types of particles.

As for your second question, the idea of our universe being a bubble-shaped brane is just one possibility in string theory. It is still a topic of ongoing research and debate, so there is no definitive answer yet. However, if we were to consider this idea, we could be on either the inside or outside surface of the brane. It really depends on how the brane is embedded in higher dimensions. It's difficult to imagine or determine from our perspective which surface we are on, as we are limited to observing our universe from within. But your idea of being in between two surfaces is an interesting concept to consider.

I hope this helps to clarify some of your questions. Keep exploring and learning about these fascinating concepts!
