As we conclude on the basis of our book Inside Stars , the ratio of the gravitational radius and the space breaking radius to the physical radius a (i.e.
With such characteristics, the collapse radius is ~ 1.2 x [10.sup.28] cm (a little lesser than the event horizon, while the space breaking radius is the same as he event horizon ~ 1.3 x [10.sup.28] cm.
where the breaking radius [r.sub.br] = [square root of 3/[??][rho]] = 4x[10.sup.13]/[square root of [rho]] cm.
We conclude that the collapsing sphere of ideal incompressible liquid transforms into a de Sitter vacuum bubble by the special case of collapse, when the radius of the sphere a equals the breaking radius [r.sub.br]
where the radius of the collapsar [r.sub.c] coincides with the radius of the sphere and the breaking radius.
It follows from (11) that the condition [??][rho][r.sup.2]/3 = 1 is the condition of space breaking, consequently the quantity [r.sub.br] = [aquare root of 3/[??][rho]] is the breaking radius. Using the expressions for the [r.sub.g] and [r.sub.br], we can rewrite (13) in the form
It was shown that the Sun would break the surrounding space, with the breaking radius [r.sub.br] = 3.43 x [10.sup.13] cm = 2.3 AU (1 AU = 1.49x [10.sup.13] cm), where 1 AU is the distance between the Sun and the Earth.
It follows from (12) that the radius of the liquid sphere (11) in the collapse condition [r.sub.c] equals its proper radius a and the breaking radius [r.sub.br], if
