We can freeze embryos? I learn something new every day.
yup, there are people alive today who were born from sperm or embryos frozen for over 10yrs. another few years and we should be able to preserve them almost indefinitely.
However, wouldn't a year in space take its toll on them?
good question
travelling outside our magnotosphere takes its toll on humans of any age. difference is that a freezer with 10,000 embryos is
alot easier and cheaper to shield from radiation than 10,000 fully grown humans.
