The discussion revolves around the implications of Schrödinger's equation in the context of extra dimensions, particularly in relation to string theory and the concept of dimensional compression. Participants explore theoretical aspects of higher dimensions and their potential applications, as well as the nature of these dimensions and their relevance to our understanding of the universe.
Participants express differing views on the applicability of Schrödinger's equation in various dimensional contexts and the nature of extra dimensions. There is no consensus on the feasibility of dimensional compression or the implications of traveling around the universe.
Some claims depend on specific interpretations of string theory and the nature of dimensions, which remain unresolved. The discussion touches on speculative ideas about the universe's structure and the nature of reality beyond observable limits.
Individuals interested in theoretical physics, particularly in the areas of quantum mechanics, string theory, and the nature of dimensions and the universe.
The simplest way is to have a circular extra dimension: If you move say 10-20 meters in a direction that's perpendicular to the three "standard" dimensions of space ("right", "forward" and "up") you have already moved all the way around the entire universe and returned to your starting point. (That number is just something I pulled out of my ***. The actual number could be bigger or smaller).mrlaughingman said:ahh yes sorry about that i was thinking about the string theory. but how can a dimension be microscopic exactly?
It seems very unlikely. In theory, space can be stretched even without the extra dimensions, but (I think) doing something like that always involves exotic matter of a type that has never been observed, and even if it exists, you'd have to squeeze a lot of it into a small space and keep it there.mrlaughingman said:but just out of curiosity could dimensional compression become reality?
It depends on what direction you're going in. If you go right, forward or up, and eventually get back to where you started (after traveling at least a few hundred billion light-years (probably much more)), that only means that space curves back on itself, or possibly that it has a non-trivial topology, like the space in the Asteroids game. Extra dimensions don't have anything to do with it.mrlaughingman said:so if i am understanding this then if you were to go completely around the universe and end were you started that's another dimension
