You should realise that magic isn't real, so if the author states that both curse (Avada Kedavra and Expelliarmus) fell on Voldemort, you can only accept is -- you cannot make experiments or something.
The two spells collided and Voldemort's killing curse deflected to himself.
Pettigrew kills him with the 'Avada Kedavra' curse on Voldemorts demands.
It didn't rebound when used on Lily or James; if it had, they would have survived. Voldemort's killing curse rebounded when he tried to use it on Harry as he was protected by the magic left by Lily's sacrifice.
There is no big significance. It is where Voldemorts curse touched him, but was unable to kill him when Harry was a baby. He was left only with the scar.
yes. He shoots the killing curse at harry but harry uses 'expeliarmus' which overpowers voldemort, voldemorts wand then flies through the air and the rebounding curse hits him.
Harry never gets hit by a cruciatus curse cast by Voldemort. Harry does get hit by a killing curse, but he survives due to lily potters love for him and the fact that he sacrificed the fragment of voldemorts soul instead of letting himself die.
Voldemort casts the killing curse onto harry which then "kills him", yet because part of voldemorts soul was inside harry voldemort only destroyed part of his horcrux and not harry.
his Death Eaters
Horcurxes are a part of Voldemorts soul
Quirinus Quirrell
Tom Riddle Sr. he was a muggle.
