Earth Cannot Be 10x Bigger

A 10 times bigger Earth would have a 10 times bigger centrifugal force, which would then be felt by travelers.

The main point of the current globe earth model is that the gravitational acceleration (g) dwarfs the centrifugal acceleration (at the Equator) being two orders of magnitude bigger.

g = 9.81 >> 0.034 = a(cf)

If you doubt in any way the 0.034 value of the centrifugal acceleration, you can check out these pages (the first three that I found):
