A new theory of gravity might explain the curious motions of stars in galaxies. Emergent gravity, as the new theory is called, predicts the exact same deviation of motions that is usually explained by invoking dark matter. Prof. Erik Verlinde, renowned expert in string theory at the University of Amsterdam and the Delta Institute for Theoretical Physics, published a new research paper today in which he expands his groundbreaking views on the nature of gravity.
This site gives the directions to make this project illustrating to students how the earth orbits the sun and how the moon goes along with. This would be a really great project to use in a science lesson to help students understand what moves around what in our solar system. ~ Lauren Feuling
Los musulmanes han realizado grandes contribuciones a la astronomía a lo largo de la historia. Algunas de ellas tuvieron lugar en Al-Andalus, que jugó un importante papel para evitar que el conocimiento sobre el firmamento se perdiese... #astronomia #ciencia
