What is cryonics?
Cryonics is the practice of preserving a human body (or brain) at ultra-low temperatures after legal death, with the goal of restoring them to life in the future once medical technology allows.
The process involves:
- Rapid cooling of the body
- Replacement of bodily fluids with cryoprotectants to prevent ice formation
- Vitrification (a glass-like solidification without crystals)
- Long-term storage in liquid nitrogen at around -196°C
This process is known as cryopreservation, and it’s scientifically grounded — but it’s also experimental.
So, does cryonics work?
Short answer: Cryonics has not yet been proven to work — because no one preserved through cryonics has been revived.
Longer answer: Cryonics is not based on current revival capability. It’s based on the belief that:
- Future medical technology will be able to reverse the causes of death.
- Advanced nanotechnology or cell regeneration will repair cellular and tissue damage.
- The identity and memories of a person are encoded in the physical structure of the brain — and can potentially be preserved.
So, the real question becomes: can the body and brain be preserved in a way that keeps the information intact for future recovery?
There’s growing evidence that cryopreservation can preserve cellular structure extremely well — especially with modern vitrification techniques.
What science supports cryonics?
Cryonics is supported by research in several fields:
- Cryobiology – the study of how cells behave at low temperatures
- Vitrification – used in preserving embryos, eggs, and organs
- Neuroscience – studies suggest brain structure (and therefore memory) may remain intact after proper preservation
- Tissue preservation – advances in cryoprotectants reduce ice damage, making whole-organ preservation increasingly viable
While full-body revival is not yet possible, the success of organ banking, reproductive preservation, and brain mapping shows promising potential.
Tomorrow.bio is helping bridge these gaps by investing in ethical, evidence-based cryopreservation — not hype.
What are the limitations?
Cryonics today is not revival. It’s preservation — keeping the body as stable and intact as possible until future science can solve the rest.
Challenges include:
- No current method to revive a vitrified human
- Unknown timelines — could be decades or centuries
- Ethical and legal questions around identity, consent, and future reintegration
- The uncertainty of whether today’s preservation will be enough for future medicine
That’s why cryonics is best viewed as a scientifically informed bet on the future — not a guarantee.
Why do people choose cryonics?
People who sign up for cryopreservation are not afraid of death — they’re curious about life. They see it as:
- A personal freedom
- A backup plan when modern medicine fails
- A way to preserve the possibility of seeing the future
- An alternative to burial or cremation — which offer no second chance
For them, even a small chance of future revival is worth preserving.
How does Tomorrow.bio approach cryonics?
At Tomorrow.bio, we offer full-body and brain only cryopreservation with:
- 24/7 standby and stabilization teams
- Medical-grade cryoprotection and perfusion
- Advanced vitrification and ultra-low temperature storage
- Transparent pricing and ethical standards
We do not promise revival. But we promise the best possible preservation and access to honest information. You can read more about our process here.
Is cryonics legal?
Yes — cryonics is legal in many countries, including across Europe and the United States, as long as it is performed after legal death.
Tomorrow.bio operates in full compliance with local laws and is committed to transparency and regulatory ethics.
What about pets?
We also offer pet cryopreservation, allowing animal companions to be preserved using the same science and care. You can calculate the cost or speak with us to learn more.
Final thoughts: possibility, not promise
So — does cryonics work?
Not yet. But it’s based on real science, growing evidence, and an optimistic view of the future. For those who believe medical technology will continue to advance — and that preservation today is better than irreversible death — cryonics offers a meaningful choice.
Whether it works depends on us, our science, our ethics, and our willingness to invest in the long game.
About Tomorrow.bio
At Tomorrow.bio, we are dedicated to advancing the science of cryopreservation with the goal of giving people and pets a second chance at life. As Europe’s leading cryopreservation provider, we focus on rapid, high-quality standby, stabilization, and storage of terminal patients — preserving them until future medical technologies may allow revival and treatment.
Our mission is to make cryopreservation a reliable and accessible option for everyone. We believe that no life — human or animal — should end because current medical capabilities fall short.
