Question

what happens when anti matter comes in the contect of black or white hole......????¿¿¿

Answer 1

i hope help you

Black holes are formed when an extremely massive star collapses in its own gravity to produce a particle of infinite (or undefined) density. To contain itself within space and time, it starts releasing antimatter. This antimatter collides with the surrounding matter and destroys it to produce energy, some of which re-enters the black hole. This ensures that a black hole is never destroyed. Similarly, a white hole is produced when an extremely large amount of antimatter collapses and forms an infinitely dense particle that releases matter

Answer 2

Heya..

Whether the infalling material is matter or antimatter makes no difference.

Fundamentally, the confusion probably comes from thinking of black holes as normal substances (and thus retaining the properties of whatever matter went into making them). Really, a black hole is a region of spacetime with certain properties, notably the one-way surface we call an event horizon. That's it. Whatever you envision happening on the inside of a black hole, whether it be a singularity or angels dancing on the head of a pin, is completely irrelevant.

The reason spacetime is curved enough to form an event horizon is essentially the due to the density of mass and energy in the area. Antimatter counts just the same as matter when it comes to mass and energy. Anti-protons have the same, positive mass as normal protons, and at a given speed they have the same, positive kinetic energy too.

Even if you wanted matter and antimatter to annihilate somewhere near/inside a black hole, the resulting photons would cause no less curvature of spacetime, as all particle physics reactions conserve energy and momentum. This is related to how you could form a black hole from nothing but radiation.

Hope it helps.
