摘要: We revisit the issue of ripples in primordial power spectra caused by trans-Planckian physics, and potential for their detection future cosmological probes. find that reasonably large values first slow-roll parameter epsilon (> 0.001), a positive can be made even if amplitude is as low 10^-4. Data from Large Synoptic Survey Telescope (LSST) proposed 21 cm survey with Fast Fourier Transform (FFTT) will particularly useful this regard. If scale inflation close to its present upper bound, new physics high 0.2 M_Planck could lead observable signatures.
