I remember that cryogenesis was deemed viable in the 80ies but essentially surface area is your enemy. Anything larger than a cat can’t be resurrected. It’s pretty bizarre really, they froze mice and microwaved them back to life.

Weird! I wonder if there is some exponential complexity going on. More neural pathways leaving more stuff that can potentially break from an uneven freeze/thaw? Or is it literally that the freezing and thawing can't happen evenly when you're too big? A brief transistional period with unfrozen outsides and frozen solid insides is probably not great for you.

I would assume it is purely because of the mass.

This. You literally can’t evaporate all the thawing agent out of the blood of the organism without substantial burns by sheer volume

That's really interesting, thank you - do you know how this was done, like in a practical sense?

Actually I got the timing wrong, it was the 50ies, but here you go:

Hmm I wonder if some kind of beamforming would work? I think that's what the Miele Dialog uses to enable you to cook a fish while it remains in a frozen block of ice
