In hardmode, how large of a gap can hallow/corruption cross?
I understand that this question has been asked loads of time, but all the forums, wikis and answers I am seeing give different answers, so I am confused in regard to what and what not the corruption/hallow is able to jump across.
That picture asks my question. But, to add a bit more, I understand that there are also other factors (such as corruptors, the infection from other directions), that might cause this area to become infected. Lets forget about those factors, all I am asking is if the corruption/hallow will be able to jump across this shaft.
