Comparing the Suppression Structures of Scientific Heresy: Galileo's Era and the Present

This paper compares the suppression of scientific heresy in Galileo's era with that in contemporary science. It examines how Galileo faced direct and visible repression from religious authorities for supporting heliocentrism, while modern science appears more free due to institutionalized and democratic structures. However, the study argues that heretical ideas in modern science can still be suppressed in subtle, dispersed ways through mechanisms such as peer review, funding allocation, mainstream academic focus, citation networks, and evaluation metrics. The paper highlights the qualitative shift from overt punishment to silence and questions whether modern scientific freedom truly allows heterodox ideas to be considered. The study aims to reconsider what freedom in science means and where a “modern Galileo” might stand.
