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

Causal Theory of Reference of Michael Devitt

Michael Devitt develops a hybrid causal theory of non-empty proper names and certain singular terms that semantically resemble them. He considers that the use of a name designates an object not by virtue of the different information we know about … Read More

Heuristics of the General Relativity

The essential principle of coordination in GR is the principle of equivalence, including a negative heuristic. The argument “is not that all reference frames are equivalent, but that the classical coordination of uniform motion in a straight line with the … Read More

Epistemology of General Relativity

Early philosophical interpretations of the general theory of relativity are very diverse, each trying to identify Einstein as a follower of that philosophy. Mach’s supporters highlighted Einstein’s attempt to implement a “relativization of inertia” in general relativity (GR), and his … 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
