Homework Help: A perfect sphere

  1. Dec 9, 2011 #1
    Suppose a perfectly spherical sphere were to exist - Pefectly uniform even at the atomic level. Then hypothetically, could this sphere withstand infinite pressure and so travel into a black hole without being destroyed?

    There would be no 'weak points' on a perfect sphere causing it to break under the pressure, right?

    Also, would this sphere reflect all light and so become invisible?

    What about tidal forces? Remember, the forces acting on the sphere will not be directed to the center of the sphere.
