Comment on I bet they're all ghosts. Getting yourself frozen just screams "unfinished business"

I doubt it. Cryogenic preservation is probably possible, but current methods likely do too much damage to the person’s tissue to ever be salvageable, especially since most of them were dead for hours before being frozen. Their brains were unrecoverable before they even entered the pods. Ideally you’d want to be frozen more or less immediately. As in “the process begins while you’re still alive and they euthanize you on the table inside the cryogenics facility” immediately.

Plus a lot of these companies experience regular refrigeration failures, which is probably what caused the corpses in the meme to liquify like that.

Agreed. Coming from a background in cryopreservation (not trying to freeze bodies), the freezing is the easy part.

While you’re correct with the time of death to time of freezing portion, the freezing process (could… potentially) be fine. Although there’s no way to tell (yet).

But the thawing process results in the most degradation, especially with thicker tissues due to uneven warming and damage from ice crystal formation (assuming the body was vitrified).

Will we ever be able to thaw these bodies and them to be viable? Maybe? Impossible currently, but who knows about the future. Although, I doubt they will be salvageable.

If it makes a difference, I will not be freezing my body when I die (not just because of the money needed), and can’t see that changing within my lifetime.

Given they’re frozen by being immersed in liquid nitrogen, how do these refrigeration failures happen? They don’t require electricity, just someone to top it up occasionally.

  Sometimes the liquid nitrogen lines to the pods fail, sometimes you get a prolonged power outage, sometimes there’s a leak in the pods themselves that allows coolant to evaporate, etc.

    you don’t really need electricity, you just need to occassinally fill the tanks up

    With liquid nitrogen, which needs to stay refrigerated to remain liquid.
