Evaluation of post-Einsteinian gravitational theories through parameterized post-Newtonian formalism

|

Proliferation of post-Einsteinian gravitational theories Right after the elaboration and success of general relativity (GR), alternative theories for gravity began to appear, which can fall into four broad categories: [1] Bifurcated theories (with the Lakatosian[2] hard core identical or very … Read More

Tests and Anomalies of Post-Newtonian Gravitational Theories

Tests of post-Newtonian theories Newton’s proposed tests In the first edition of Principia, Newton considered that the experiments with the pendulum would allow him to decipher the different types of resistance force and their variation with speed. It recognizes the … Read More
