Why didn't anyone ask Bobby a simple question: If you are afraid of Heaven because you won't know anyone, what do you think about the fact that, even if cryogenics works, by the time you come back, all of your friends will be old and your parents will most likely be dead? Would you still want to come back if everyone you know is gone? They set up that question perfectly...and didn't ask it. Of course a young boy would be afraid of going to Heaven if it meant he would be alone. But no one asked him if he would be afraid to be on Earth if it meant he would be alone and the people he most cared about were in Heaven.And just as an aside, the problem with freezing someone for cryogenics before we know what we are doing is that even if we figure out the process, any person who was frozen too early would have been frozen 'incorrectly' (allowing ice crystals to form) and not able to be thawed.
