The resulting events destroy several universes and a couple of dimensions disappear as well. Not that we really notice it, we couldn't see them anyway*.
The only noticeable effect in our universe was a single apple disappearing on its way to the ground, because the apple never existed in the first place. Well it did exist previously in a sense, if you think of time in a linear fashion, but it never really existed. Its non-existence caught up with it in the end. Its a shame really, because this one apple would have fed a starving child who would have later brought international peace and global prosperity if he hadn't died of malnutrition.
