Use of Black Holes ???

We see there use as the hub of spiral galaxies. The axis is used like
the hub of a wheel is used with spokes coming out of it so that its rim
turns in unison. The stars being the spokes. Hawking
has BH evaporating,and that is bad thinking. What BH do and this was
their main function before the first original BB took place was to
separate cosmic space's two energies "virtual" and "real". Lots of good
scientific thinking has shown me how gravities great force can
accomplish this action. In both micro,and than in the macro realm.
Reality is just before entering a black hole is the most fascinating,and
dynamic of all spacetimes. bert
