31 Oct 1996 | | Journal: | Phys.Rev. D55 (1997) 4591-4595 | | Subject: | hep-th gr-qc | | Abstract: | We show that a class of 3+1 dimensional Friedmann-Robertson-Walker cosmologies can be embedded within a variety of solutions of string theory. In some realizations the apparent singularities associated with the big bang or big crunch are resolved at non-singular horizons of higher-dimensional quasi-black hole solutions (with compactified real time); in others plausibly they are resolved at D-brane bound states having no conventional space-time interpretation. | | Source: | arXiv, hep-th/9610252 | | Services: | Forum | Review | PDF | Favorites | |
