A popular question — rooted in sci-fi and hope

It’s one of the most frequently asked questions about cryonics: Can a person be frozen and brought back to life?

Movies suggest yes. Current science says: not yet — but it’s more complex than that.

In reality, no one is frozen in the traditional sense. Instead, people who choose cryonics undergo vitrification — a process that preserves their body and brain after legal death in a glass-like, ice-free state at -196°C.

While revival has not yet been achieved, many experts believe that the necessary scientific building blocks are beginning to take shape.

‍

Freezing vs. vitrification: a crucial difference

To understand the debate, we must clarify terms:

• Freezing leads to ice crystal formation, which damages cells and tissues irreversibly.
• Vitrification, used in modern cryopreservation, prevents ice formation by using cryoprotectants. The result is a glass-like solid state that preserves the structural integrity of tissues — especially the brain.

So, humans are not actually frozen in cryonics. They are vitrified — a far more advanced and preservation-friendly technique.

Has anyone ever been revived?

As of today: no.

No human preserved through cryonics has ever been revived — and providers like Tomorrow.bio are transparent about this. Cryopreservation is not yet reversible, and revival technologies do not currently exist.

But the question isn’t whether we can revive people today. It’s whether we can preserve them well enough now to make revival possible when medical technology catches up.

‍

What science would need to make revival possible

Reviving a vitrified person would require progress in multiple fields:

• Neuroregeneration: repairing or replacing damaged brain tissues
• Advanced nanotechnology: to repair cells at a molecular level
• Whole-body regeneration: restoring function to organs, blood vessels, and tissues
• Memory and personality retention: ensuring that the identity encoded in the brain remains intact

These fields are still developing, but there are reasons for hope. Scientists have already:

• Preserved embryos, sperm, and eggs through vitrification and revived them successfully
• Frozen and revived simple organisms
• Made significant progress in mapping brain structure and storing it

Cryonics simply extends that logic to the human body.

‍

So why do people still choose cryonics?

Because for many, the chance — however slim — is better than none.

People who opt for cryopreservation believe:

• Death from today’s diseases may not be permanent in the future
• The brain encodes identity, and preserving it may preserve the self
• Future medical technology will be capable of cellular and neurological repair
• Burial and cremation offer no opportunity for revival — only cryopreservation does

It's a long-term investment in possibility, not a promise of immortality.

The Tomorrow.bio approach

At Tomorrow.bio, we offer full-body cryopreservation with:

• 24/7 standby and stabilization
• Cryoprotectant perfusion to enable vitrification
• Gradual cooling to -196°C
• Long-term storage in a secure European facility
• Transparent pricing and ethical guidance

We also provide full assistance with life insurance planning, which is how most members fund their preservation.

Can pets be preserved too?

Yes. For many, the love shared with pets is no less profound than with people. That’s why we also offer pet cryopreservation, applying the same scientific standards to your animal companions.

‍

So… can humans be frozen and revived?

Not yet.

But we can preserve people in a scientifically rigorous, non-destructive state using vitrification. We can maintain their bodies and brains indefinitely. And we can invest in research that may one day unlock revival.

Whether you call it hope, science, or long-shot optimism, cryonics offers the one option that burial and cremation never can: a future-facing second chance.
