de Sitter Complementarity, TCC, and the Swampland
  Motivated by the coincidence of scrambling time in de Sitter and maximum
lifetime given by the $\textit{Trans-Planckian Censorship Conjecture}$ (TCC),
we study the relation between the de Sitter complementarity and the Swampland
conditions. We study thermalization in de Sitter space from different
perspectives and show that TCC implies de Sitter space cannot live long enough
to be considered a thermal background. We also revisit $\alpha$-vacua in light
of this work and show that TCC imposes multiple initial condition/fine-tuning
problems on any conventional inflationary scenario.
