A Modified Gravity Theory: Null Aether
Metin Gurses, Cetin Senturk
General quantum gravity arguments predict that Lorentz symmetry might not hold exactly in nature. This has motivated much interest in Lorentz breaking gravity theories recently. Am…
From Smooth Curves to Universal Metrics
Metin Gurses, Tahsin Cagri Sisman, Bayram Tekin
A special class of metrics, called universal metrics, solve all gravity theories defined by covariant field equations purely based on the metric tensor. Since we currently lack the…
Kerr-Schild--Kundt Metrics are Universal
Metin Gurses, Tahsin Cagri Sisman, Bayram Tekin
We define (non-Einsteinian) universal metrics as the metrics that solve the source-free covariant field equations of generic gravity theories. Here, extending the rather scarce fam…
