How Newtonian Mechanics Get Black Holes Wrong

Newtonian mechanics permit arbitrarily large speeds. A sufficiently
sturdy cannon with sufficient propellant could fire a boulder at a
ballistic speed of 1,000,000c, which would cause the boulder to escape.
Light emitted from a stationary source below the 2πΊπ/π2
boundary will briefly rise up before going down.
An object can travel to an arbitrary distance from a black hole just
as long as it acceleration opposite that of gravity exceeds πΊπ/π2,
even if its speed never reaches c.
Any object can remain stationary above a spinning black hole,
regardless of how fast it is spinning, as long as it is accelerating sufficiently.
