(I don't advise it to you, however).

You had me at "very strange," but this resolved any doubt. Please continue!

Why should I always get into these things? I should learn to be silent... [

Ok, it's my responsibility...

Ehm, the anti-gravity is...

the gravitational field itself!

Explanation (easy part, and OF COURSE, you WON'T ask me to get into the not-easy part too [

]):

1. A

static field as electrostatic field has mass. I mean

real invariant mass. I don't want to go in the demonstration of it, trust me.

2. At this point one should ask: but then, has the static gravitational field a mass too? The answer is yes, for the same reason. BUT: because of the "minus" sign in the formula of the field, the mass of the field

*is negative*!

At this point we have an incredible amount of problems, because the behaviour of a negative mass' object is "mind blowing" (can I say so?):

a) if you push an object with negative mass, it accelerates in the opposite direction!

b) Two bodies, one with positive mass and the other with negative mass, will move indefinitely one after the other: the positive mass attracts the negative but the negative repels the positive (Yes, I've written correctly!) so the positive will "escape" the other, which will go after it!
