Cosmological consequences of short distance physics
Inflation can act as a space-time microscope for Planck or string scale effects, leaving potentially observable traces in the primordial perturbation spectrum. I discuss two frameworks that were used recently to study this phenomenon: nonlinear dispersion and short distance uncertainty. : 9 pages. T...

| Summary: | Inflation can act as a space-time microscope for Planck or string scale effects, leaving potentially observable traces in the primordial perturbation spectrum. I discuss two frameworks that were used recently to study this phenomenon: nonlinear dispersion and short distance uncertainty. : 9 pages. Talk presented at COSMO-01, Rovaniemi, Finland, August 29 -- September 4, 2001 |
