Is that a valid number for the schwarzschild radius of the universe?
Schwarzschild radius, also called gravitational radius, the radius below which the gravitational attraction between the particles of a body must cause it to undergo irreversible gravitational collapse.
Are we under irreversible gravitation collapse?
Not when the universe, the verticality of the universe, is already there at 0-point (as Stephen Hawking told those physicists who were sweating their reductionist findings in their math). In other words, once more, our whole local universe that we are in is already the largest Black Hole of them all with a constant Horizon, a duality of Horizon, it shares [with / as] the Big Bang (up and out) / Planck (down and in) / Infinite (collapsed) Horizon . . . so nothing to bother about. (The trees are in the forest || The forest is in the trees.)
The (.... / .... / Infinite) collapsed Horizon has non-local gravity ingredient permanently counterpoised to all its constituent local centers of gravity. Total them all up to their infinity (their "infinities") of gravity and all you have is the Big Bad Boy's 'Horizon' already -- permanently constant (so what if its redundant) -- in existence [as / to] the rim 'Infinite' (collapsed) Horizon. The wormhole-like [hook around] dimensions of White Hole / Black Hole Horizons (Horizon). As Horizon it deals in both, including its infinity of 0-point-portals ((1) point || (2) portal).
