Once special relativity was on the firm observational and theoretical footing, it was appreciated that the Schrödinger equation of quantum mechanics was not Lorentz invariant, therefore quantum mechanics as it was so successfully developed in the 1920s was not a reliable description of nature when the system contained particles that would move at or near …
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 there a more fundamental theory? More than just strings? Read More »
