Colliding Kaluza-Klein Bubbles
We construct an exact solution describing the collision of two Kaluza-Klein “bubbles of nothing” in 3+1 dimensions. When the bubbles collide, a curvature singularity forms which is hidden inside an event horizon. However, unlike the formation of ordinary black holes, in this case the spacetime resembles the entire maximally extended Schwarzschild solution. We also point out that there are inequ...
متن کاملCollapse of Kaluza-Klein bubbles.
Kaluza-Klein theory admits “bubble” configurations, in which the circumference of the fifth dimension shrinks to zero on some compact surface. A three parameter family of such bubble initial data at a moment of timesymmetry (some including a magnetic field) has been found by Brill and Horowitz, generalizing the (zero-energy) “Witten bubble” solution. Some of these data have negative total energ...
متن کاملWhen Black Holes Meet Kaluza-Klein Bubbles
We explore the physical consequences of a recently discovered class of exact solutions to five dimensional Kaluza-Klein theory. We find a number of surprising features including: (1) In the presence of a Kaluza-Klein bubble, there are arbitrarily large black holes with topology S. (2) In the presence of a black hole or a black string, there are expanding bubbles (with de Sitter geometry) which ...
متن کاملBubbles Unbound: Bubbles of Nothing Without Kaluza-Klein
I present analytic time symmetric initial data for five dimensions describing “bubbles of nothing” which are asymptotically flat in the higher dimensional sense, i.e. there is no Kaluza-Klein circle asymptotically. The mass and size of these bubbles may be chosen arbitrarily and in particular the solutions contain bubbles of any size which are arbitrarily light. This suggests the solutions may ...
متن کاملSchwinger meets Kaluza-Klein
We study Schwinger pair creation of charged Kaluza-Klein particles from a static KK electric field. We find that the gravitational backreaction of the electric field on the geometry – which is incorporated via the electric KK Melvin solution – prevents the electrostatic potential from overcoming the rest mass of the KK particles, thus impeding the tunneling mechanism which is often thought of a...
