The idea that black hole formation might also be universe formation is quite old; I don't know what the new contribution of Poplowski's work is. (For the avoidance of doubt, I simply mean "I don't know" and not , e.g., "I suspect there is none".) Lee Smolin made an ingenious observation: if that's so, and if it happens that in the "daughter" universe the constants of nature are slightly (and variably) different from…

Only we do not have competition for shared resources or any other pressure.

Earlier quoted context omitted.

Such a phenomenom would break the law of conservation of mass and energy so bad it will go back to its mother and cry all night.

One way or another, the beginning of the universe has to violate conservation laws, doesn't it?

Not necessarily. E.g. the total energy/mass of the universe could sum up to 0, if you take potential energy in a gravitational field from a reference point infinitely far away (and other such tricks).

The total charge charge is probably very close to zero anyway. Total impulse can be made zero by choosing a suitable coordinate system. And so on for the other conserved properties.

And if so, what are the ontological implications of it creating universes with a strong anthropomorphic bias?

Antropomorphic bias? How so? Did I miss something?

I think GP meant anthropic bias.

"If future experiments reveal that our universe appears to rotate in a preferred direction, it would be indirect evidence supporting his wormhole theory, Poplawski said." I was wondering, If the universe is our only point of reference, and everything in it is (at a whole) rotating at the same speed and in the same direction, how we could tell?

Rotation requires acceleration, since your direction is changing, so you can tell by the forces upon you.

It is worth noting that the estimated mass of the universe is the same as the mass of a black hole whose event horizon has the radius of the visible universe. This coincidence is rather striking and has been the subject of much speculation, though nobody has been able to make anything useful come out of it. If this theory manages to predict this relation within the created universe, that would be evidence for the the…

This is interesting news, but not very surprising strangely enough. If you assume that the next approximation to Newton's gravity equations are similar to Maxwell's equations (thereby introducing a secondary field analogous to B, the magnetic field) then you can do back of the envelope calculations that get you interesting results including this one - i.e. our universe's radius is of the order of Schwarzchild's radiu…
