Gravity Going Up & Down Thinking

OK This is a mind experiment. I'm an astronaut and I'm falling towards
another astronaut and we hit feet first. We are in reality standing on
each other. I say gravity pulled me down to him,and he thinks the same
thing. Reality is yes I came down to him,but he also came up to me. Up
and down fits like north and south magnets Here it is again
Should we have a tunnel going through the Earth to China and I jumped in
and at the same time a China man jumped in we would meet feet first at
the center of the Earth. We would meet at the same speed but I being
fatter would have the greater force,and "push" him back,and that push
back would mean to him that oc "push theory" for gravity works. Go
figure its really all GR Inertia and accelerating motion Its in reality
"All Einstein" When Einstein and I had that very short discussion
we talked on inertia and gravity,and touched a little on this,and its
the reason I woke up this morning to post it. Hope I got my thoughts
out clearly Bert
