Universe creation, entropy, and extra dimensions Academic Article uri icon


  • Gravitational bags contain a domain wall outside of which they look compact, but inside there is a solution in which, in certain circumstances, the extra dimensions explode. We show that it is energetically possible for a collapse of the domain wall to lead to the creation of a huge universe containing a large quantity of entropy. This can proceed via quantum tunneling through a “wormhole” region.
