Sorry, no etymologies found.
On the other hand, the fact it involves "braneworld" scenarios makes me feel good about having my fictional FTL drive in my upcoming novel Marseguro operate in "branespace."
The theory holds that the visible universe is a membrane hence "braneworld" embedded within a larger universe, much like a strand of filmy seaweed floating in the ocean.
Mini Black Holes: If a radical new "braneworld" theory of gravity is correct, then scattered throughout our solar system are thousands of tiny black holes, each about the size of an atomic nucleus.
If we combine braneworld cosmology and cosmological natural selection, then we obtain a scenario in which self-reproducing universes not only evolve by natural selection, but in which they collide and interact.
The braneworld theory predicts that relatively small "black holes" created in the early universe have survived to the present.
"If the braneworld theory is correct," they said, "there should be many, many more braneworld black holes throughout the universe, each carrying the signature of a fourth dimension of space."
For the braneworld model would have notable consequences.
The "braneworld universe" has five dimensions -- four spatial dimensions plus time -- compared with the four dimensions -- three spatial, plus time -- laid out in the General Theory of Relativity.
General Relativity says that such primordial black holes would have evaporated away by now, so finding them would make the braneworld hypothesis tenable.
Petters of Duke base their work on a recent theory called the type II Randall-Sundrum braneworld gravity model.
