Is the Universe a blackhole? Tell me why I'm wrong!

(1) First conjectu Universe is a blackhole.

Sometimes the answer is just so obvious, that you wonder why other's
haven't thought of it already. Well, the fact is that probably lots of
people have thought of it, but no one has been able to come up with a
conclusive argument yet. Here's mine:

Mass of the Observable Universe ~~ 3.4×10^54 kg (kilograms)

http://www.wolframalpha.com/input/?i=mass+of+universe

Radius of the Observable Universe = 46 billion ly (light years)

http://www.wolframalpha.com/input/?i=radius+of+universe

The Schartzchild Radius of a mass the size of the Universe = 533.7
billion ly (light years)

http://www.wolframalpha.com/input/?i...%9710%5E54+kg+

So, 46 billion light-years 533.7 billion light-years, therefore the
universe is sitting in a volume much less than its own Schartzchild
Radius. Therefore, the Universe is inside a blackhole. That's just based
on the observable universe's mass, the greater universe must be even
more massive and therefore even more likely that we're in a blackhole.

(2) Second conjectu Universe started out (Big Bang) as a whitehole.

The Universe started out as a whitehole, because the Cosmic Microwave
Background Radiation looks just like the event horizon of a whitehole.
Einstein's equations predict that whiteholes should exist just as much
as blackholes. Blackholes and whiteholes have similar features,
including event horizons; whiteholes however have white event horizons
which are incredibly bright rather than incredibly dark. In either case,
you cannot see what's behind the border of an event horizon whether it's
a black or whitehole. The CMBR is completely perfectly opaque, just like
the event horizon of a whitehole should be.

My conclusion? The Universe is a container with a wall made by a
blackhole event horizon, which prevents us from viewing anything outside
of it. At the same time, we started out as a whitehole. So the whitehole
is the spout that filled up this blackhole.
