Colliding bubble worlds

Colliding Bubble Worlds

We consider a cosmological model in which our Universe is a spherically symmetric bubble wall in 5-dimensional anti-de Sitter spacetime. We argue that the bubble on which we live will undergo collisions with other similar bubbles and estimate the spectrum of such collisions. The collision rate is found to be independent of the age of our Universe. Collisions with small bubbles provide an experi...

Colliding with a Crunching Bubble

In the context of eternal inflation we discuss the fate of Λ = 0 bubbles when they collide with Λ < 0 crunching bubbles. When the Λ = 0 bubble is supersymmetric, it is not completely destroyed by collisions. If the domain wall separating the bubbles has higher tension than the BPS bound, it is expelled from the Λ = 0 bubble and does not alter its long time behavior. If the domain wall saturates...

Cosmological Perturbations Generated in the Colliding Bubble Braneworld Universe

We compute the cosmological perturbations generated in the colliding bubble braneworld universe in which bubbles filled with five-dimensional antide Sitter space (AdS5) expanding within a five dimensional de Sitter space (dS5) or Minkowski space (M5) collide to form a (3+1) dimensional local brane on which the cosmology is virtually identical to that of the RandallSundrum model. The perturbatio...

Colliding Worlds: Issues Relating to Language Translation in Accounting and Some Lessons from Other Disciplines

This paper explores implications of language translation in accounting. It draws on research on translation in other disciplines, and on insights from applied linguistics. It examines practical problems and solutions explored in other disciplines that we deem relevant to accounting. The paper also examines ideological, cultural, legal and political consequences of translation. We find that the ...
