    They already did, but their mass can not cease to exist.

    The Universe would get larger and the galaxies would break up.

    Nothing.

    Galaxies would start expanding since their central core would no longer be there.

    But the effect on our solar system is nothing.

    We would not know for thousands of years.

    At least at first we might not know.  After all, we can't "see" black holes anyway.  But at some point we would notice unexpected gravitational anomalies.  Then stuff might happen.

    It actually depends on HOW they disappeared.  Since a black hole has an incredible amount of energy stored within itself, we might see some supernovaes bright enough to light up the night sky.  Which would imply a broad-spectrum energy burst, which would lead to increased rates of skin and other types of cancer.

    It would probably change the laws of the universe.

    It would change Quantum Mechanics altogether

     The whole of the Universe, could be put in reverse

    Yikes !!!

    what if it did? nothing you would see in your lifetime. Gravity propagates at the speed of light and the nearest black hole is thousands of light years away. 

    If the black hole at the center of our galaxy disappeared, the stars in the galaxy would assume new orbits around the center of the galaxy which would take millions of years before it was noticeable.

    It would have drastic effects on the curvature of space-time, our galaxy may be organized around a super-massive black hole. I couldn't imagine the changes in the mechanics of stars and planets.
