DESCRIPTION:I will describe the structure and cosmological signatures of i
 nstantons mediating tunneling between de Sitter minima. For generic potent
 ials the Coleman-de Luccia instanton does not necessarily exist\; when it 
 does not\, the instanton which contributes to the decay rate is the Hawkin
 g-Moss instanton. I will interpret this solution and describe the resultin
 g cosmology\, and argue that an observation of significant positive curvat
 ure would rule out the possibility that our universe arose from any transi
 tion from a neighboring minimum in the string-theory landscape.\n\nhttps:/
