Cryostatis, or Cryopreservation, is the freezing of biological material to preserve it. Speculatively, it could be used to preserve rare or endangered species, or keep people on the brink of death around long enough until a time comes when they can be cured. While there are people out there who have been “preserved”, there currently aren’t any success stories, or “resurrections.” Unless you live in the Doctor Who universe!
We know that according to the Doctor’s adventures, the human race survives far into the future, either surviving as clouds of gas or downloads or skin trampolines - but there were also those that cryogenically froze themselves and their art and culture, in order to defy their natural lifespans and persist into the future. When the Doctor, Harry and Sarah-Jane landed on Space Station Nerva, they uncovered a band of indomitable humans who did just that!
Unfortunately, due to a Wirrn infestation, the humans overslept by 10,000 years (imagine waking up after all that time and then having to fight a load of massive parasitic insects!). With the Doctor’s help, they were able to defeat the Wirrn and start re-inhabiting the earth. Not too sure about the guy whose pod Harry opened, though. Reckon he’s a goner!
Time Travel
"So, all of time and space, everything that ever happened or ever will. Where do you want to start?"
And now, what you’ve all been waiting for… Let’s talk about time travel! You’ll notice we didn’t pick an episode for this one. Surely, it’d be easier to list the Doctor Who stories that don’t feature time travel! (5 points to whoever does that first).
Instead, check out this video of Professor Brian Cox explaining how time travel is in fact, something that happens in our everyday lives. We’re not saying that you can hop in a telephone box or end up in pre-historic times, or in the year five billion, but you might be surprised!
