A Metric Theory of Gravity with Condensed Matter Interpretation
Abstract
Description
We define a metric theory of gravity with preferred Newtonian frame (X^i(x),T(x)) by
L = L_{GR}
+ Ξg^{mn}δ_{ij}X^i_{,m}X^j_{,n}
- Υg^{mn}T_{,m}T_{,n}
It allows a condensed matter interpretation which generalizes LET to gravity.
The Ξ-term influences the age of the universe. Υ>0 allows to avoid big bang singularity and black hole horizon formation. This solves the horizon problem without inflation. An atomic hypothesis solves the ultraviolet problem by explicit regularization. We give a prediction about cutoff length.
