Do all non-Christians go to Hell?

Do only non-Christians who have been informed of Christianity but haven't chosen to convert go to Hell? Do all non-believers have the opportunity to have revelations of Christ even if they haven't even met a Christian? Do they go to Hell if they don't? Do righteous pagans go to Hell like in the Divine Comedy? Do Jews go to Hell? What do you believe happens to non-Christians in the afterlife?
