text: what is the psi of the earth's core...? ... compared to the psi of our strongest pressuration chambers? i'm wondering if it is possible to create a gravitational field by creating enough direct pressure onto the fabric of space. wiki gives number for the pressure at the bottom of the mantle: http://en.wikipedia.org/wiki/outer_core#mantle of 1.4 matm  the highest pressurization of gases is typically not much more than 400 atm.  note the mantle's pressure of 1.4 matm.
