If they are correct, the idea of a black hole with a singularity at the center may be just a fantasy."

    How does this sound:
    1. Nothing can exceed the speed of light.
    2. If you release a pulse of light and try to follow it you will never catch up to it.
    3. Within the event horizon, the escape velocity is greater than the speed of light, which means that light emitted inside will never escape.
    4. Since you can't overtake any light you emit, and all the light you emit can't escape, you can't escape either.
