Frozen in time: the world of cryonics

August 16, 2011 | Comment icon 8 comments

Cryonics involves the freezing of a deceased person's body in the hope of being revived in the future.
Cryopreservation is becoming more and more popular with some individuals paying vast sums of money to have their remains frozen upon their demise. Those without as much to spend can also opt for a cheaper alternative - to have only their head preserved.
Over five years, photographer Murray Ballard has been given unprecedented access to the world of cryonics, which involves freezing a dead person's body in liquid nitrogen until, proponents argue, technology has advanced enough to bring them back to life.

Is Walt Disney still frozen?

what if reincarnation is real, and your soul goes to another body, and then you get revived?

Waste of space and money. Freezing ruptures living cells and we don't know how to prevent it yet. If you are frozen your cells are ruptured and when they thaw you out you will just turn to goo after you are out a while, unless you are pretreated with something to stabilize. Might make a fun SciFi movie. Goo zombies.

Walt Disney is anti-semitic....keep him on ice. Some reptiles and other forms of life in Artic are able to bear low temperatures even when almost all their bodies are made of ice because of glycerol in their livers or Dimethyl sulfoxide or DMSO (that thing with the stink between garlic and cabbage) and certain cryoprotector sugars. But the process of freezing has to be very slow because it's toxic in our weather. Frozen semen preserves genetic material.

This has never made sense to me. First of all, I know that freezing a human body causes all the water in the body to expand, thus damaging the cells. If we had some kind of anti-freeze chemical in our bodies (like some animals and reptiles do) then perhaps this wouldn't happen. The other issue is that these people already wait until they are dead before having their remains frozen. Once your dead, your dead. If they chose to be frozen before dieing, then in theory they could be thawed, and given a cure for whatever disease they had. However, they wait until they die before being frozen, I can'... [More]

what if reincarnation is real, and your soul goes to another body, and then you get revived? My guess is that the revived body would by dead. No soul, no life. However, a different soul could chose to reincarnate in that revived body.

So even if the person could be brought to life, it would have no knowledge to it, and not have the same personnality.
