| « Origin of matter out of pure curvature » |
|
N. Dadhich |
| We begin by motivating the need for higher dimension even for classical description of gravitational dynamics and then construct an example of a black hole being formed out of pure curvature in Einstein-Gauss-Bonnet gravity by splitting spacetime into the usual 4-dimensional spacetime and a 2-dimensional space of constant curvature. This way, we establish the fundamental reciprocity between matter and gravity (spacetime curvature) and creation of ""matter without matter. |
