Unification and distant scales- Unified Theory

Why can’t we just build an accelerator to test the predictions of string theory? Because the obstacles are much bigger than money or social commitment. This section uses units where (Planck’s constant)/2p and the speed of light = 1. This choice of units is called natural units. With this choice, mass has units of inverse […]

Is there a more fundamental theory? More than just strings?

If different string theories are related, then maybe they represent different limits of a bigger, more fundamental theory. To understand the presence of objects in string theory that are not strings, but higher-dimensional objects, or even points, it helps to know the formulation of Maxwell’s equations in the language of differential forms, because this is
