It is the custom of Earth people
to try and avoid

We destroyed your space buoy
as a simple act of self-preservation.
When we attempted to move away from it,
it emitted radiation harmful to our species.
If you've examined our ship
and its tapes,
you know this to be true--
loud humming :
You now have seven minutes left.
Kirk tries to reason with Balok.
