Karkaroff betrayed many Death Eaters during his attempt to avoid imprisonment in Azkaban. After Voldemort’s rebirth, Karkaroff didn’t return to Voldemort. He was eventually caught and killed by Death Eaters in 1996.

After a brief pause where Dumbledore showed his first sign of alarm during the duel, Voldemort attempted to possess Harry, in the hopes that Dumbledore would sacrifice his pupil to kill the Dark Lord. However, the power of Harry’s love made it impossible for him to possess Harry for long and he was forcibly ejected.

In the the film adaptation of Harry Potter and the Half-Blood Prince, Harry and Dumbledore Apparated at the Astronomy Tower, although it is said that no one can Apparate or Disapparate within Hogwarts.

Apparition is a magical form of teleportation, through which a witch or wizard can disappear (“Disapparate”) from one location and reappear (“Apparate”) in another. According to Harry, apparition is also accompanied by a very unpleasant squeezing sensation, as though being sent through a tight rubber tube.

While human teleportation currently exists only in science fiction, teleportation is possible now in the subatomic world of quantum mechanics — albeit not in the way typically depicted on TV. In the quantum world, teleportation involves the transportation of information, rather than the transportation of matter.

Based on these two insights, Bohr argued that a quantum theory can never explain classical physics. Some physicists argue that we just haven’t worked hard enough, and that we do fundamentally live in a quantum world, and that we can reproduce classical physics from purely quantum rules.

According to quantum mechanics, the answer appears to be “no”, and time appears to be in fact smooth and continuous (contrary to common belief, not everything in quantum theory is quantized).
