Gravitational Physics: Testing Gravity from Submillimeter to Cosmic : Proceedings of the VIII Mexican School on Gravitation and
General Relativity today is able to explain many known gravitational effects at the level of the solar system. However open problems remain like dark matter and dark energy present at galaxy and or cosmic scales has only recently been explored. The VIII Mexican School on gravitational and Mathematical Physics "speakable and unspeakable in gravitational physics: testing gravity theories from submillimeter to cosmic scale" was proposed to discuss and exchanges present and future gravitational tests.
