Might Our Universe Have Been Born Inside a Black Hole?

Let is settle for a while before shouting from the rooftops that it's a groundbreaking bit of science. Many others have suggested before that black holes may be feeding baby universes, but it hasn't stuck.
1. Wouldn't this invalidate the laws of thermodynamics, with energy pouring into the universe out of "nowhere"?
2. Conversely, shouldn't the universe be evaporating?
This example kinda kills the whole romantic-fantasy element of universes in black holes, since you would only get 1 child universe per parent universe, and it would not really be noticeable from our point of view. (what happens to those poor universes when 2 of the black holes combine??)
Any good reason why or why not I should take their theory seriously?
What could be another example. Yep, no I think that's it.
Arguing about 'the illusion of thought' really sounds like medieval philosophy.
I recommend 'I of the Vortex: From Neurons to Self' by Rodolfo Llinás for a more modern take on these issues.
The very idea of a black hole is based on the concept of continuity, an idea that is not only illogical (it leads to an infinite regress), but is not even scientific in the Popperian sense of falsification. Even Einstein, Mr. Continuity himself, had doubts about continuity.
Worst of all is the idea that somehow time has a direction of flow, i.e., an arrow. The idea that we are moving in time in one direction or another is a conceptual disaster. Why? Because time cannot change by definition...
The problem with the physics community is that theirs is an incestuous science that has been spawning hideous monstrosities for some time now. Their bunker mentality (the public is stupid and is the enemy) prevents them from considering other points of view, especially views that contradict their worldview.
And so forth. This sets off most of the alarms on the crackpot detection test (references to Einstein, assertions that all physicists are stupid, nonsensical use of terminology et cetera). But it does it in such a way that I think I see a self-aware troll at work, rather than a garden-variety crackpot.
As for the paper, I'll give it a "meh" for now. It doesn't seem to be crackpot, but it's not necessarily true either; it's just speculative, and doesn't seem to make any testable predictions.
That's a funny comment (I realize it's not yours, hugh3), because this guy is flying in the face of respected theoretical physicists. Time is immutable? It cannot have a direction? Blogga please.
"The problem with inflation is that it needs an additional theory to explain why it occurs and that's ugly."
It's always a bad sign when scientist start looking for beauty rather than go where the facts lead them even if it's ugly.
On top of that, it's not like there haven't been many many many many very intelligent people trying to solve this problem.
He seems to try to solve the problem semantically, i.e. try to re-interpret the facts into a more aesthetically pleasing model which is exactly where it becomes pseudoscience.
To the best of my knowledge (and I am no scientist) the information that we have about the universe simply can't lead to a solution to the problem if it can be solved at all.
Only if we get additional information about our universe will we be able to perhaps find another way to interpret what this all means.
But cherry picking in the current knowledge base won't magically create a theory.
It's not about interpretation it's about facts.
The facts lead us to two "competing" theories that just can't be combined.
Maybe he is onto something, but then he needs to make some predictions with it.
(That tidbit notwithstanding, I am insufficiently informed to have a worthwhile opinion on this subject.)
You forgot about the elephants.
