Not really.
In hell there is no technology of any kind. Not even a hammer. Everything is done by hand. We’re talking pre-stone-age. It’s hard work being in hell. Even the demons work their asses off. They don’t even have whips to goad people into working harder.
Heave, on the other hand, is beyond technology. I mean, their technology comes from the end of time. When (if) we get there, it will all look like magic to us. We won’t know how anything gets done, but it’ll all be done from some far future technology we can’t even imagine now.
So really, there won’t be an internet in either place—hell because it has no technology at all and heaven because it’s technology is so far advanced we won’t even be able to see it.
