2. Note that the Einstein group approaches but never reaches the Poincare group as the flat spacetime ( special relativity limit ) is approached.
3. In flat spacetime and linear coordinatization, " differences " in coordinates,, can be treated as a contravariant vector.
4. In the absence of any ( large ) energy-momentum density-flux GR predicts a flat spacetime AKA Minkowski space-time.
5. Special relativity is restricted to flat spacetime, " i . e . ", to all phenomena without significant influence of gravitation.
6. It's difficult to find flat spacetime in a sentence. 用flat spacetime造句挺難的
7. For flat spacetime, the metric is a constant tensor so the Christoffel symbols vanish, and the geodesic equation has the solutions of straight lines.
