Abstract: Systems and methods are provided for determining a property, e.g., density, of a geological formation based on Einstein's theory of gravitation. A gravitational potential difference is determined between two positions of the geological formation by measuring a frequency shift of radiation travelling from a source to an absorber of a differential gravimeter. The differential gravimeter can be a part of a downhole tool. The gravitational potential difference determined can be used to determine the property of the geological formation.
