Hell is a lower dimension 'orb' where the evil people will end up after the dimensional transition. We cannot see it, we can only see 3rd Dim now. I imagine 'god' selects who goes or not, or perhaps it is just a karma read. There these people, in spirit form, will continually reflect on their life deeds. They will understand the problems they caused and feel the pain of their victims, over & over. They have to 'let go' and follow the light as we do, just like we have done in this lifetime. Only thru heartfelt capitulation can enlightenment be found. Do it now or later, the choice is yours.
If you don't ever make it your being will not ascend to higher dimensions and one day you will be left behind forever. That is bad.
