Nonsymmetric Gravity has Unacceptable Global Asymptotics

TL;DR

This paper demonstrates that nonsymmetric gravity theory cannot produce physically acceptable solutions at both past and future null infinity, highlighting fundamental issues with its asymptotic behavior compared to General Relativity.

Contribution

It provides a detailed analysis of the asymptotic properties of nonsymmetric gravity solutions, revealing inherent limitations in their global behavior.

Findings

Nonstationary solutions lack acceptable asymptotics at both null infinities.

Good future null infinity behavior requires advanced potentials.

Unphysical behavior occurs at past null infinity with these solutions.

Abstract

We analyze the radiative aspects of nonsymmetric gravity theory to show that, in contrast to General Relativity, its nonstationary solutions cannot simultaneously exhibit acceptable asymptotic behavior at both future and past null infinity: good behavior at future null infinity is only possible through the use of advanced potentials with concomitant unphysical behavior at past null infinity.
