Feynman thought that time ran faster in higher gravity because his light

 No. Clocks don't run faster "in higher gravity".
Proper clocks are not affected by acceleration or gravitation.
Proper clocks always run at their proper rate.

And in the meantime in the real world - improper
clocks with improper rate keep measuring improper
t'=t in improper seconds. The reality is soooooo
improper.
