404-compliant, and in
<http://www.umich.edu/~mctp/SciPrgPgs/events/2008/SS08/EP_Mich.pdf> one can
read in “Conclusions”:

| The EP [equivalence principle; the ed.] is one of the most precisely
^^^^^^^^^^^^^^^^^^^^^^^^^
| tested principles in all of physics with many broad implications
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
| […]
| No evidence yet for a breakdown of the EP. For example:
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
| the weight of gravity agrees with Einstein’s prediction to
| better than 1 part in 10³
^^^^^^^^^^^^^^^^^^^^^^^^^
| assuming CPT symmetry, anti-H falls with the same
| acceleration as H to within 2 parts in 10¹⁰
^^^^^^^^^^^^^^^
| laboratory proof that gravity is the dominant long-range force between
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

| In this activity we looked at early experiments of gravity, two different

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
