## Main Question or Discussion Point

Raymond explains in his radically modern physics text on page

http://physics.nmt.edu/~raymond/classes/ph13xbook/node61.html [Broken]

that a constantly accelerated observer (acceleration a) never increases his distance from

the point x_0-c^2/a where x_0 is the point where he started his acceleration.

He argues that this is the reason that on earth, we are accelerated outwards,

but nevertheless stay at constant distance from the center.

BUT: c^2/g is about 1 light year, whereas the radius of the earth is 6400 km.

How does his explanation fit with these numbers?
