Abstract:
"Bubbles of nothing” are a dramatic
instability of spacetimes with compact
extra dimensions. A hole appears in
spacetime, inside of which there is neither
space nor time: there is literally “nothing”.
Witten showed that they may nucleate by
quantum tunneling. I will discuss bubbles
of nothing that nucleate instead by
thermal fluctuation (or by a part-quantum
part-thermal hybrid process), and exhibit
a high-temperature/low-temperature
duality with the nucleation of caged black
holes.
