On the Phase Space of Block-Hiding Strategies in Bitcoin-like networks
Assaf Shomer
We calculate the probability of success of block-hiding mining strategies in Bitcoin-like networks. These strategies involve building a secret branch of the block-tree and publishi…
A pedagogical explanation for the non-renormalizability of gravity
Assaf Shomer
We present a short and intuitive argument explaining why gravity is non-renormalizable. The argument is based on black-hole domination of the high energy spectrum of gravity and no…
Towards observable signatures of other bubble universes
Anthony Aguirre, Matthew C Johnson, Assaf Shomer
We evaluate the possibility of observable effects arising from collisions between vacuum bubbles in a universe undergoing false-vacuum eternal inflation. Contrary to conventional w…
IIA moduli stabilization with badly broken supersymmetry
Michael Dine, Alexander Morisse, Assaf Shomer +1
Scherk-Schwarz compactification in string theory can be defined as orbifolding by an R symmetry, a symmetry that acts differently on bosons and fermions. Such a symmetry can arise…
On Witten's Instability and Winding Tachyons
Michael Dine, Assaf Shomer, Zheng Sun
We investigate, from a spacetime perspective, some aspects of Horowitz's recent conjecture that black strings may catalyze the decay of Kaluza-Klein spacetimes into a bubble of not…
A note on Gauge Theories Coupled to Gravity
Tom Banks, Matt Johnson, Assaf Shomer
We analyze the bound on gauge couplings , suggested by Arkani-Hamed et.al. We show this bound can be derived from simple semi-classical considerations and holds in spa…
