It really doesn’t take all that much math in order to establish that a
EH thin shell comprised of 1g/cm3 density would amount to 2.666e47 kg,
giving a surface escape velocity demand of 8.674e7 km/sec or 289 times
faster than the speed of light, and that’s if the entire internal
volume of this EH sphere were absolutely devoid of any other mass.. *If
this same thin EH shell was instead comprised of a superfluid of solid
helium at .214 g/cm3 would still easily provide more than sufficient
mass of 5.7e46 kg, so that its escape velocity of 4.01e7 km/sec at the
EH surface of solid helium is offering 134 times greater than the
speed of light.


So, where’s the need of any solid BH body of mass?


Why not permit hollow and empty EH spheres to exist?

*Of course once inside of this extremely thin EH shell is going to
represent zero gravity regardless of the EH shell density and its
mass, offering a light year diameter sphere of containing whatever.
