comment Is the earth expanding?
A down vote for stating the possible and no explanation. Don't worry I still believe you cant split the atom and god created the earth therefore it's dimensions cant chage.

comment Rocket launch from a mountain
Whiteout the location of the mountain the answer is incorrect. The diameter relative to the rotation at that latitude is not that same as on the equator. The question posted is not the question I asked.

The height of the mountain becomes more critical once your realize the amount of speed you need at the relise point so I was going to ask next is the propulsion needed to live the ramp at just under mach 1. But the sight controllers don't to.
