[time-nuts] GENIUS by Stephen Hawking (PBS TV),

[Bob Camp]

Hi

The real answer to the question lies in the scientific method its self. You never ever rely 
on any single experiment, no matter how well done. There is no single experiment that 
can ever prove a point “beyond any doubt” (yes that is deliberate). Instead  the answer is to
look at *all* of the experiments and to actively encourage multiple tests of a theory from many
different directions. The theory only holds if *all* of the experiments support it. You get a nice 
big prize (named after that dynamite guy)  if you disprove the prevailing theory. THAT is why 
you accept the theory rather than any single experiment. There never ever is any single experiment
that will demonstrate any point against total doubt.

I don't know if one can ever "prove beyond doubt" since the second half of that equation belongs to another person. But one can go a long way to plan everything before and during an experiment to address the first half of the equation, the part you do control.

But one thing I always wanted to do was a repeat trip just to make sure it wasn't dumb luck the first time. Maybe a different method, maybe without kids, maybe a different mountain. And the PBS / Hawking invitation was the perfect excuse to fulfill that goal.
