• How Newtonian Mechanics Get Black Holes Wrong

    From Michael Ejercito@21:1/5 to All on Sun Dec 3 17:44:46 2023
    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 2𝐺𝑀/𝑐2
    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 𝐺𝑀/𝑑2,
    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.
