Where did the four-dimensional star and the black hole come from?
What holds up the world?
It is held on the back of a giant turtle.
What holds up the turtle?
There is a giant elephant under each foot.
What holds up the elephants?
It’s elephants all the way down!
I think they are content to explain anything; e.g., the uniform temperature problem, and aren’t trying to explain everything. So we are as puzzled by what came before their 4-D universe as we’ve always been about what preceded the Big Bang. Do I claim to understand how their idea explains away the temperature problem? Heck, no, I wish! :-)
bush did it....
but seriously
in the so called natural world...Nothing comes from nothing...ever
From the collapse of the five dimensional star?
Just like the Hindu model of the cosmos, the universe is a sphere riding on the back of a giant tortoise. Which in turn is riding on the back of a still larger tortoise, and so on ad infinitum.
Like the old guru said, "it's tortoises all the way to the bottom!"

PS The large fleas have smaller fleas upon their backs to bitem.
The smaller fleas, still smaller fleas and so ad infinitum.
