One attempt to reconcile quantum mechanics and general relativity into a theory of everything is string theory, which suggests that electrons and quarks are oscillating one-dimensional 'strings'. String theory remains controversial since it requires unobserved additional dimensions and has yet to make ...

With our current level of understanding, the problem of making string theory predictions is not one of "solving" the theory, but rather of trying to determine whether there are any generic expectations. Within this context, we discuss what it would mean to predict low energy supersymmetry, and...
According to this theory, as the strings vibrate, twist and fold, they produce effects in many, tiny dimensions that humans interpret as everything from particle physics to large-scale phenomena like gravity. String theory has been held up as a possible "theory of everything," a single ...
Numbers of the form 8k+28k+2 appears to be relevant for string theory. For k=0k=0 one gets 2 dimensional string world sheet, For k=1k=1 one gets 10 spacetime dimensions and for k=3k=3 one gets 26 dimensions of bosonic string theory. For k=2k=2 we get 18. I don'...
A heterotic string theory in four dimensions is constructed by compactifying the Ex E/sup '/ heterotic strings from 26 to 4 dimensions via a manifold T/sup 22//G. The theory is modular invariant. In the low-energy limit, there are three families of chiral fermions with exactly the same ...

We also investigated what type of substructure is easily or hardly understood by the model using dimension-wise similarities of MACCS keys, whose details are written in Supplementary Note2. No remarkable tendency was observed in the results, and the similarities of most of the dimensions converged...
