If the focus of a website is on how to teach (how to design a course, what classroom activities to include), it should go in this category. If the focus is on the subject (for instance, lecture notes giving a general introduction to the subject of black holes), they should go in the parent category Black_Holes.Sites that feature material related to the teaching of black hole physics, such as course syllabuses, ideas for class activities and "teacher's kits".
Only websites that focus on the observational aspects of black hole physics should go here - sites with a more general scope should be submitted to the parent category Black Holes.Lists sites containing information about the observational evidence for black holes (stellar dynamics, accretion disks, X-ray observations).
Submissions should focus on research in black hole thermodynamics and Hawking radiation. The websites submitted be based on generally accepted theories and models (for everything else, there''s the category Relativity/Alternative).This category is about the study of black holes as thermodynamic objects (where the black hole mass is inversely proportional to its temperature, and the surface area proportional to its entropy), including quantum effects such as Hawking radiation.
Submissions should contain information on wormhole solutions to Einstein''s equations, or on creation and use of such wormholes. Sites which do not have a basis in physics should be redirected to Physics/Relativity/Alternative.Wormholes are hypothetical entities representing sections of spacetime that are warped in such a way as to connect two locations in space and time, possibly over great distances.
