Limits RegistryThe Cave of the Crystals (Cueva de los Cristales), discovered in 2000 about 300 m below ground in the Naica mine, Chihuahua, Mexico, contains selenite (gypsum) crystals up to about 12 m long and weighing up to an estimated 55 tonnes — the largest natural crystals known. They grew over hundreds of thousands of years in hot, mineral-rich water.

Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
