A comparison of Hořava-Lifshitz gravity and Einstein gravity through thin-shell wormhole construction
Farook Rahaman, P. K. F. Kuhfittig, M. Kalam +2
In this paper we have constructed a new class of thin-shell wormholes from black holes in Hořava-Lifshitz gravity. Particular emphasis is placed on those aspects that allow a compa…
