| 1. | The test particles were lost exponentially with a half life of 553 Myr.
|
| 2. | That way the potential is independent from the test particle properties.
|
| 3. | A stationary spacetime metric, making the orbit of a nearby test particle precess.
|
| 4. | The easiest case for the application of a test particle arises in Newtonian gravity.
|
| 5. | The Hamiltonian for test particle motion in Kerr spacetime is separable in Boyer Lindquist coordinates.
|
| 6. | It is instructive to look at the total relativistic energy of a free test particle.
|
| 7. | Calculations showed that when test particles were inserted into it, they flew away from each other.
|
| 8. | Where m is the mass of a test particle moving with velocity \ vec { v }.
|
| 9. | In fact, test particles do not accelerate toward massive objects in 2 + 1 dimensional general relativity.
|
| 10. | We might mention here that in general, the motion of test particles in pp-wave spacetimes can exhibit chaos.
