If one of the reasons for wishing to be frozen, is to see what the future looks like, then there is an alternative; Einstein to the rescue! Just strap yourself into a spaceship capable of reaching within a few % of the speed of light, and fly around for a bit. No need to wait till you're at death's door and turned into a corpsicle. Just head on out there for a few years at relativistic speed. By the time you slow dow…
The flaw in your theory being that it would take you equally as long to slow down as it would to reach that speed. So you would age out on the deceleration. I suppose you could accelerate in an orbit around earth to maintain contact. But my understanding of relativity is poor
I'm sure producing one of these things is more possible right now than freezing/thawing/reviving a human.
Alternatively, to compensate for how long it would take to speed up and slow down, just have our intrepid time-o-naut climb into their suspended animatio--- oh heck ;)
