String Interactions: Effects on Matter & More

In summary, interactions between closed and open strings determine the properties of the string and ultimately affect the behavior of matter. While originally thought to be mostly closed loop, new string theories suggest that strings are likely to be open with endpoints connected to a membrane. Closed loop strings, such as the predicted graviton, are not limited to our dimensions and may explain the weak force of gravity. Particles are composed of multiple strings, and string theory suggests that matter is composed entirely of strings.

There are two types of strings, closed and open, and they interact and stuff. How do these interactions affect matter or anything else?

Well the two types of strings allow for different properties. Since the way strings viberate determine what properties the string will have; what fundamental particle it will become the way the string operates is very important onto the effects it will have. It was originally thought that most strings would be closed loop strings, but new string theories actually point out that strings are likely to be open with end points. These endpoints will be connected to a membrane and traped to our dimensions. (String theory requires extra 11 dimensions) However closed loops strings wouldn't be limited to our dimensions and would be free to travel into the higher dimensions. This is why the graviton is predicted to be a closed loop strings. If there is a graviton and it is a closed loop string then this would explain why gravity is so weak. It is weak because it only stays in our dimension for a very limited amount of time.

I hope this somewhat helped

Oooh yes it did, I learned much, but how the strings interact was my question.

I read a string was about 100 billion billion times smaller than a proton, so would or would not that mean that particles are composed of more than one string?

Is only matter composed of string?

1. What is string theory and how does it affect matter?

String theory is a theoretical framework that attempts to reconcile the theory of general relativity with quantum mechanics. It proposes that particles are not point-like objects but tiny, one-dimensional strings that vibrate at different frequencies. The interactions between these strings can result in the formation of matter and other particles.

2. How does string theory explain the four fundamental forces of nature?

String theory suggests that the four fundamental forces - gravity, electromagnetism, strong nuclear force, and weak nuclear force - are all manifestations of the interactions between strings. The varying frequencies of string vibrations give rise to the different forces, and their interactions determine the behavior of matter.

3. Can string theory be tested or proven?

At present, string theory is still a theoretical framework and has not been proven or disproven. It is difficult to test because it proposes the existence of extremely small strings that cannot be directly observed. However, scientists are working on ways to test some of the predictions of string theory, such as the existence of extra dimensions.

4. How does string theory relate to the concept of parallel universes?

Some versions of string theory suggest the possibility of multiple universes or dimensions. This is because the theory requires the existence of extra dimensions beyond the three spatial dimensions we are familiar with. These extra dimensions could theoretically exist in parallel to our own universe, but they have not yet been observed or proven.

5. Can string theory help us understand the beginning of the universe?

String theory has been proposed as a possible explanation for the origin of the universe, as it suggests that the Big Bang may have been caused by the collision of two parallel universes. However, this is still a highly debated topic and there is currently no conclusive evidence to support this idea.
