Cryogenics is people being frozen and thawed to live in future years. It is possible to preserve a living being but there is no technology to thaw them. It is highly unsafe but can lead to amazing scientific discoveries. Krzysztof Brodzinski. CERN, Geneva, Switzerland. With contribution from: S. Claudet, D. Delikaris, L. Delprat, G. Ferlin, E.
