mattercan
Mattercan is a term used in speculative science and science fiction to describe a compact containment device designed to encapsulate, stabilize, and preserve a discrete quantity of matter. In many depictions, a mattercan stores matter in a non-biological, non-chemical state and prevents decay, enabling long-term preservation, rapid transport, or staged release. The concept emphasizes maintaining the microstructure of the contained material rather than altering its composition, though some variants permit reconfiguration or reconstruction on demand.
A typical mattercan comprises a sealed chamber surrounded by energy fields, including a quantum-state memory and
The idea has its roots in late 20th and early 21st-century fiction and has appeared in speculative
Limitations and ethics are commonly noted: substantial energy requirements, risk of state corruption or replication errors,
