20. More on KS throat cloaking…
Was thinking about recent paper by Alex Buchel and Lev Kofman… and found that I have a couple of naive questions:
1) cloaking is 5 dim picture (well, 10-dim) - i.e., throat for bulk CY observer is seen as AdS black hole. What is the picture for 4dim observer, the one who lives on the brane and whose spacetime is approximately dS? For example, I don’t quite understand what this black hole cloaking means for eternal inflation 4 dim observer experiences… Does cloaking mean that the value of the inflaton field cannot become too large?
2) both cloaked throats emit radiation into the bulk from their horizons. What does evaporation mean from the point of view of 5 dim observer - shrinking of horizon? Is there a thermal radiation establishing between two cloaked throats?
