Exploring the New Geometry of String/M-Theory

In summary, Edward Witten's lecture discusses how String/M-theory suggests a new type of geometry that focuses on interactions between quantum world sheets rather than space/time points. This concept is still being researched and there is currently no definitive answer. More information can be found in references such as the one provided.

I'm watching a lecture by Edward Witten here:

In it, he mentions that String/M-theory seems to be hinting toward a new kind of geometry where you don't talk about space/time points, but the interactions between quantum world sheets (around 37:00 minute mark.)

Does this new geometry have a name? What work's being done on it? Where can I read more?

But these world sheets are embedded in 10-dim. "background", so this cannot be the final answer

We are still waiting for Ed to publish his background-ind. notion of string theory, I guess :P

You're dead right!
 

Related to Exploring the New Geometry of String/M-Theory

1. What is the role of geometry in string theory?

Geometry plays a fundamental role in string theory as it provides a mathematical framework for understanding the interactions between strings. The geometry of spacetime dictates the behavior of strings and their interactions, allowing for the prediction of physical phenomena.

2. How is geometry used in the formulation of string theory?

The formulation of string theory involves the use of mathematical tools from geometry, such as differential geometry and topology. These tools are used to describe the structure of spacetime and the interactions between strings.

3. Can string theory explain the geometry of the universe?

String theory offers a possible explanation for the geometry of the universe through its concept of extra dimensions. These extra dimensions, beyond the three spatial dimensions we experience, may be responsible for the observed geometric properties of the universe.

4. How does geometry in string theory differ from traditional geometry?

Geometry in string theory is based on the concept of curved spacetime, as opposed to the flat spacetime of traditional geometry. In string theory, the geometry of spacetime is dynamic and can change in response to the presence of strings and energy.

5. Are there any experimental confirmations of the geometric predictions of string theory?

At this time, there are no direct experimental confirmations of the geometric predictions of string theory. However, some predictions, such as the existence of extra dimensions, can potentially be tested through high energy particle experiments or astronomical observations.
