### MIT 8.224 Exploring Black Hole by Prof. Edmund Bertschinger

- einstein field equations
- gravity
- black holestudy of physical effects in the vicinity of a black hole as a basis for understanding general relativity
- astrophysics
- and elements of cosmology. extension to current developments in theory and observation. energy and momentum in flat spacetime; the metric; curvature of spacetime near rotating and nonrotating centers of attraction; trajectories and orbits of particles and light; elementary models of the cosmos. weekly meetings include an evening seminar and recitation. the last third of the semester is reserved for collaborative research projects on topics such as the global positioning system
- solar system tests of relativity
- descending into a black hole
- gravitational lensing
- gravitational waves
- gravity probe b
- and more advanced models of the cosmos.

Study of physical effects in the vicinity of a black hole as a basis for understanding general relativity, astrophysics, and elements of cosmology. Extension to current developments in theory and observation. Energy and momentum in flat spacetime;...Some questions about the cause of gravity

Questions: 1. Is gravity a force? 2. What do you think is the way mass is coming into existence within the quantum vacuum implying? 3. When you flip the observational plane and think about: What effect has micro gravity for the formation of planets, stars or galaxy clusters? 4. Does a magnet ...Tags: physics, ideas, einstein, general relativity, gravity, theories, discoveries, history, dark matter, gravitational waves, bicep, graviton, quantum gravity

Are there Gravitational Waves?

This is a guest Post by Georg Drakenberg, AthensGravitational Waves? It is reliable the detection and ''discovery'' of gravitational waves? Are we sure? Hmmm..not so..This that General Relativity predicted and defined-mistankely-as ''gravitational waves'', simply, is a sort of quantised dislocati.........
