<p class="MsoNormal"><span lang="EN" style="font-size:10.0pt;font-family:"Arial",sans-serif">Abstract:</span><span lang="EN"> The idea that the Universe underwent a period of superluminal expansion, known as inflation, has gained considerable traction with
the advent of precise measurements over the past decade+. One of the key predictions of inflation is a spectrum of primordial density fluctuations that remains nearly scale-invariant over 15-25 decades in distance scale. The near scale-invariance of primordial
perturbations over the roughly 3 decades over which the spectrum has been measured so far remains one of the theory's greatest successes. Still, it is interesting to think whether that spectrum can be measured over the remaining 12-22 decades, all of it at
distance scales smaller than those that can be probed by the cosmic microwave background or galaxy surveys. I will discuss some ideas for accessing these smaller scales.<o:p></o:p></span></p>
