Altho I don't want to pretend I'm fluent on the composition of blackholes, I'd say "Only if ALL of the black hole is antimatter". Antimatter is just like matter, except that the electric charges of electrons and protons are reversed from the familiar. The stars and dust and blackholes of the Andromedae galaxy next door could be composed completely of antimatter, and not be a problem unless it collided with our own Milky Way.

BTW, I just read this 50-y.o. book last weekend, "Accelerators: Machines of Nuclear Physics". It describes "...the purest demonstration [ of equivalency between matter and energy, per E=mc^2] is the effect know as 'pair creation'"... and then describes how an xray that travels too close to the nucleus of an atom can be "frozen" into 2 electrons, one positive, one negative, the positive one is antimatter and is called a positron. Inversely, if a positron and an electron meet, both are totally aniliated into a burst of xrays. Fug, I didn't know that.

Electrons are very light, and their energy-equivalent is only 0.5Mev. Since pair creation yields 2 particles (one positron, one electron), you'd need only twice that amount, 1.0Mev, to make your own antimatter, and a device that could provide that could damn near fit on you kitchen table and actually not cost a fortune. Killer science fair project, huh?

White holes are similar to black holes except white holes are ejecting matter verses black holes are absorbing matter. In 1916, Karl Schwarzschild derived the first model of a black hole using Einstein's theory of general theory of relativity. Nothing, not even a particle moving at the speed of light, can escape the gravitational pull of a black hole. The existence of white holes is implied by a negative square root solution to the Schwarzchild metric for space-time-matter continuum.. It is important to remember that black and white holes can be composed from matter or antimatter.

Probably not. Most of the antimatter that was created at the Big Bang was annihilated with an equal amount of normal matter. The universe we know is just the 'leftovers'. The likelihood of any antimatter surviving anywhere is rather remote, and throwing it into a black hole would only expose it to even more matter.
