In General > s.a. black hole
phenomenology;
gravitational constant; gravitational
radiation; gravitomagnetism [including
brane].
* Status: 1989, Experimental
gravitation is now becoming a major part of general relativity, which is finally
recovering a balance between theory and observation;
This pushes the theory to justify better its approximations; Also, new tests
are being devised, gravitational lensing being one of the most rigorous.
* Bounds on PN parameters:
For the non-linearity parameter, 
< ×
10–3;
For the curvature parameter, 
–1 < 10–3 (VLBI
and quasars), = (4.8 
5.7) ×
(2.1 2.3) × 10–5 (2003,
Cassini spacecraft) [below, 
:=
4 – – 3, & 
=
std error].
