But I dunno if human hibernation has any proof of concept at all, though... and it's possibly less interesting, I think, because it's less complicated and sciencey.
Humans are mammals, and we have proof of mammals hibernating. And I haven't found the concept lacking in "scienciness" or complexity as I've written about it. If anything, I find it far more conceptually refreshing than the corpsicle cliche.
Probably better to work with a larger micro-BH, one that doesn't give off as much Hawking radiation, and get power instead from the radiation given off by infalling matter. You can "turn it off" just by cutting off the matter supply.
Come on, you know what I meant. It's common, accepted usage that "relativistic speed" means "travel at sufficient fractions of c that relativistic effects become nontrivial." That's even in the dictionary, so it's not like I'm employing a nonstandard usage.
The description says, "they return after awakening from suspended animation to find that their ship-board AI has sent them on a relativistic tour of the stellar neighborhood while they slumbered, dilating time so severely that nearly 200 years have passed on Earth." That suggest something a hell of a lot faster than 0.2c. If they intended for the crew to have been in cryosleep for nearly 196 years anyway, why bother even mentioning time dilation? Clearly the intent is that far less shipboard time passed.
