Towards the Emergence of Cyclic Universes with Scale-invariant fluctuations
Date: Friday, October 17th
Time: 2:30 pm
Place: 5280 Chamberlin
Speaker: Tirthabir Biswas, Pennsylvania State University
Abstract: Tolman pointed out that if a cyclic universe model has<br>
to be consistent with the second law of<br>
thermodynamics, the cycles must inevitably shrink to<br>
zero as one goes back in time (cycles). I will provide<br>
a simple cosmological paradigm which avoids this<br>
&quot;super Big Bang&quot;. Moreover we will see that in these<br>
&quot;Emergent cyclic models&quot; new mechanisms for generating<br>
scale-invariant fluctuations can naturally emerge.<br>
