Could You Really Be Frozen Like Han Solo? Scientists Dive into Cutting-Edge ‘Carbonite’ Technology!

A British chemist has taken a fun look at whether Han Solo’s freezing in carbonite from Star Wars could happen in real life. While it remains a fascinating idea, we’re still quite far from making it a reality.

Published for Star Wars Day, the study raises big questions about human cryopreservation. Can we really replicate something so fantastic?

Gallium: A Metal with Potential

Dr. Alex Baker, a chemist at the University of Warwick, highlights gallium as a candidate for mimicking the look of carbonite. Uniquely, gallium is liquid at room temperature but solidifies just below 30°C. Researchers have even used it to put nematode worms in a dormant state, a process known as anhydrobiosis.

Imagine a human-sized mold, about two meters tall, filled with gallium. It could achieve a display similar to the iconic scene in Star Wars. However, Dr. Baker cautions that this would be incredibly heavy—comparable to two Volkswagen Golfs—requiring serious support.

Biological Barriers

Even though the science is intriguing, there are major biological hurdles. Humans cannot enter anhydrobiosis like some tiny organisms. Trying to remove water from our cells or lower our body temperatures uniformly would be fatal. Dr. Baker starkly noted, “You wouldn’t be able to do this to a human without ending their life.”

Current cryogenic methods using substances like liquid nitrogen work for small biological samples—think IVF embryos—but scaling these processes for entire humans isn’t feasible. Our organs wouldn’t freeze evenly, leading to oxygen deprivation or dangerous carbon dioxide buildup.

Concerns About Gallium

Gallium isn’t seen as highly toxic, but we still don’t know much about how it affects human tissue. According to Sigma-Aldrich, exposure might cause nausea, coughing, or skin irritation. Dr. Baker stresses that we don’t yet fully understand how gallium would interact with complex biological systems like the human body.

Even though this idea delights Star Wars fans, the reality is that freezing a human in gallium is not just impractical—it’s likely deadly.

The Bigger Picture

Recent advancements in sleep science and metabolic suspension hint at progress, but true suspended animation is still a dream. Dr. Baker humorously quipped, “Right now, you’re more likely to build a working lightsaber than freeze someone like Han Solo.”

In a world where we are constantly exploring the frontiers of science, this quirky idea shows the blend of imagination and reality. As we push the limits of what we know, perhaps the fantasy of suspended animation isn’t as far-fetched as it seems.
