In order for cryogenics to work, blood vessels have to be smaller. Successful attempts have been made with hamsters and the like. But as soon as you try with larger creatures, the evidence suggests that enabling unfreezing requires a way to undo (or prevent) catastrophic damage to any kind of tube, which - because of how temperature works with liquids - is basically impossible due to how long it takes to freeze larger things such as a human head or body.
I've been reading on this a whole lot, and unless quantum physics change (and thereby the laws of the un... (read more)
One of the obvious resurrection routes is via digitizing frozen brains. My intuitive sense is that we're more likely to get the imaging and virtualization tech before we get the detailed nano-tech that could repair all the cells.
You have a QM based proof that cryonics can't work? I'm sure we'd all be very interested to see the details.
