Colliding 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 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 ...

Colliding Dice Probabilities

LetK, L be congruent regular polyhedra in R. Let g denote a rigid motion of R, that is, g(x) = Φx+τ where Φ is a 3×3 rotation matrix and τ is a translation 3-vector. The polyhedraK, g(L) are said to touch ifK∩g(L) 6= ∅ but int(K)∩int(g(L)) = ∅. Alternatively, we may think of ΦL moving toward K in the direction τ , stopping precisely when the two polyhedra collide. Let us sample the space SO3 of...

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...
