# Predictions of the pseudo-complex theory of Gravity for EHT observations: I. Observational tests

## TL;DR

This paper discusses observational tests of the pseudo-complex theory of gravity, which predicts significant differences from standard General Relativity in EHT observations of the Galactic Center, potentially allowing for empirical validation.

## Contribution

It summarizes the observational tests for the pseudo-complex gravity theory and highlights its distinct predictions compared to standard GR.

## Key findings

- Significant differences in intensity profiles between pseudo-complex gravity and GR.
- Predicted observable differences in EHT data of the Galactic Center.
- Potential to empirically distinguish between the two theories using EHT observations.

## Abstract

A modified theory of gravity, avoiding singularities in the standard theory of gravitation, has been developed by Hess & Greiner, known as the pseudo-complex theory of gravitation. The pc-GR theory shows remarkable observational differences with respect to standard GR. The intensity profiles are significantly different between both theories, which is a rare phenomenon in astrophysics. This will allow robust tests of both theories using Event Horizon Telescope (EHT) observations of the Galactic Center. We also predict the time evolution of orbiting matter. In this paper we summarize the observational tests we have developed to date. The theory is described in the second paper of this series (Hess et al. 2019, referred to as paper II hereafter).
