Common misconception, mostly thanks to 14th-ish century pop culture.
Ask any priest and they'll tell you hell isn't really a place, it's just the absence of God. Basically souls that rejected God during their mortal time aren't invited to the party, and presumingly sit in their own personal pods or some shit but the point is they're just isolated from everything but they're own thoughts. Which desu is pretty the worst kind of hell imaginable.
You know there was that one experiment, early 1900s I believe, they raised like 40 newborn infants in a completely sterile environment, never engaging socially with them. Just strictly feeding and medical care. The babies, while physically healthy and less than half a year old, would first give up trying to engage socially, then get a quiet uncooperative demeanor for a few days, and then die. I think it proves humans need social activity to live. 
Heaven is the eternal life after death that Jesus talked about. Hell, imo, is eternal death.

What about the lake of fire mentioned in revelations ?

I don't see why your little 'isolationist pod' can't be floating around in the lake of fire. It also said something about the plumes of smoke of your regrets extend forever up and up, so I'm wondering if the fire is more metaphorical too
