String theory postulates the entire universe is made up of one dimensional strings of vibrating energy one Plank length (10^-33 cm) long. Because they are finite length (size), it follows there must be a density based on number of strings in some given volume of space. What is the density of those strings in number of strings per unit space? Is it a uniform density or heterogenious over space? Does it make sense to define density over 4D space or 11D space? Why?

I'm not sure if any properties such as density has even been attempted to determine due to fact that the nature of what strings truly are hasn't been determined, if they really exist at all. For instance, the fact that gravity as a force is seemingly much weaker than the other basic forces, like the electromagnetic, may be due to strings that cause gravity may be able to travel through 11d space, while strings responsible for other forces are stuck in our 4D space.

Im not sure how you could prove the string theory unless our entire universe is like one big dimension with other dimensions above or below us representing the 11, there is just one universe and it has all the dimensions wrapped into one, OR planets and stars represent different densities or dimensions. Maybe and this is just throwing it out there, but maybe to prove there are other dimensions i know theres this theory, but no one has actually found a way to explain this so why not start testing the different densities of our planet. Whos to really say that the earth is solid it might have different layers that correspond with different dimensions thats all governed by a central source or the sun. im not sure exactly what is the next step in physics, but at some point someone will have to find a way to prove where the other dimensions actually are and how to get there right?
