The hope is that science will advance to the point that eventually humans will find a cure for whatever ailment killed the person, whether it’s cancer, congenital illnesses, or traumatic injuries. There’s some talk of doing it to a living person, but it’s not reversible by current technology.” Typically, a person is cryogenically preserved immediately after death.

“They have to be legally dead, as far as cryonics is concerned. “This process isn’t currently applied to living people,” says Best. As such, it was fortunate that Han Solo survived freezing in the first place.ĭarth Vader, who experienced carbonite freezing in his younger years, probably knew it was safe, but the fact remains that it definitely wasn’t designed for living beings. This highly reactive substance, used to power starship blasters, needed to be stabilized for transport but didn’t share humanoids’ unique biological needs. Lando Calrissian’s mining facility was set up to process tibanna gas and encase it in blocks of carbonite so it could be shipped safely. Here’s the thing, though: The carbon freezing chamber in Cloud City didn’t utilize any sort of cryoprotectants because, unlike in other cinematic depictions of cryogenic sleep, it wasn’t made to preserve humans. Cryonics companies avoid freezing by replacing a patient’s blood with a cryoprotectant, a liquid that will become viscous as it cools but won’t form crystals that could damage the tender cells and tissues of the human body. To put it crudely, think of freezer burn but inside of you. This process of vitrification is key to cryonics, allowing the human body to cool without experiencing the cell damage that can accompany crystallization. “The water in their body is actually replaced with a vitrification solution to prevent ice formation so that the tissues harden like glass rather than freeze.” “The patient is cooled down, and their blood is replaced,” he explains. In fact, Best doesn’t even like to use the word “freeze” to describe cryonics. Unlike carbonite freezing, though, cryopreservation is a gradual process, involving some very specific precautions meant to help protect the sensitive tissues of the human body against the harm that can occur during freezing. Much like carbonite freezing, cryopreservation involves cooling a body from the outside. “That sounds very similar to what is actually being done in practice by cryonics organizations,” Best, the former president and CEO of the Cryonics Institute, tells Inverse. He hasn’t seen Empire, but he says carbonite freezing seems similar in principle to cryonic preservation, in which human bodies are preserved at extremely low temperatures. And while the feelings we feel during that famous scene are real, carbonite freezing is (currently) not.īut what if it were? Could our hero survive the freezing process? And if so, could he be successfully thawed? We spoke to cryonics expert Ben Best to find out. The carbonite chamber fills with clouds of thick, white vapor as Han Solo, his face scrunched up in anxious anticipation, disappears in the carbonite gas. In one of the most iconically frustrating scenes in all of modern cinema, Han Solo gets frozen in carbonite at the end of Star Wars: Episode V - The Empire Strikes Back.
