SUMMARY:Towards the Emergence of Cyclic Universes with Scale-invariant
  fluctuations\, NPAC (Nuclear/Particle/Astro/Cosmo) Forum\, Tirthabir 
 Biswas\, Pennsylvania State University
DESCRIPTION:Tolman pointed out that if a cyclic universe model has<br>
 <br>
\nto be consistent with the second law of<br><br>
\nthermodynamic
 s\, the cycles must inevitably shrink to<br><br>
\nzero as one goes ba
 ck in time (cycles). I will provide<br><br>
\na simple cosmological pa
 radigm which avoids this<br><br>
\n&quot\;super Big Bang&quot\;. Moreo
 ver we will see that in these<br><br>
\n&quot\;Emergent cyclic models&
 quot\; new mechanisms for generating<br><br>
\nscale-invariant fluctua
 tions can naturally emerge.<br><br>
