5 Things Interstellar's Science Gets Right (And 5 It Doesn't)

2. We Can Freeze Fertilised Eggs

The suspended animation that the astronauts go under in Interstellar is still in its infancy - plenty of people have agreed to be frozen upon their death, but nobody's actually been successfully woken up yet - but another aspect of the mission's plan B that is entirely sound is the shelves full of frozen, fertilised eggs that are supposed to help the human race carry on on whatever new planet they find themselves. Whether or not they could stand up to being packed away on a spaceship and flung through the stratosphere has, well, yet to be tested, but the basic idea's sound. Freezing and storage of eggs is done using liquid nitrogen, removed from a patient whilst under anaesthetic and often helps with couples who are having trouble conceiving, or want to make sure they can have kids at a later date (often after serious illness like cancer reduces their chances). Usually they can only be stored for the better part of a decade, but nobody's bothered to apply the theory of relativity to how fertilised eggs age when they're flying through space with Anne Hathaway.
