Contribution

It provides the first analysis of gravitational wave velocity in the NDL gravity theory, revealing it is subluminal and discussing potential experimental implications.

Findings

Gravitational waves in NDL theory travel slower than light.

The study offers a scenario for experimental verification.

Implications for gravitational wave detection and theory validation.

Abstract

We examine the propagation of gravitational waves in the new field theory of gravitation recently proposed by Novello-De Lorenci-Luciane (NDL). This examination is done on a solvable case corresponding to a spherically symmetric static configuration. We show that in NDL theory the velocity of gravitational waves is lower than light velocity. We point out some consequences of this result and suggest a possible scenario for its verification.
