Gravitational geons on the brane Kermode, Daniel John


Gravitational geons, if they exist, represent a candidate for cosmological dark matter observations. Gravitational Geons that are nonsingular, asymptotically flat, topologically trivial spacetime solutions are not possible in General Relativity. The purpose of this thesis is to investigate whether such geons are possible on a 3 dimensional brane embedded in a 4+1 dimensional spacetime. Our approach is to identify the characteristics of a candidate spacetime solution on the brane, choose an example spacetime that exhibits those characteristics and determine if it corresponds to a gravitational geon.
