Limits RegistryPUBLIC RECORD
Limits RegistryResearchers using nanocrystalline diamond anvils with toroidal tip geometry achieved static pressures exceeding 600 GPa (6 million atmospheres) in the early 2020s, roughly double what conventional single-crystal diamond anvils can sustain before failing — pushing laboratory static compression closer to the pressures found at Earth's core-mantle boundary.
The question, scope, and sources behind this Registry record.
Researchers using nanocrystalline diamond anvils with toroidal tip geometry achieved static pressures exceeding 600 GPa (6 million atmospheres) in the early 2020s, roughly double what conventional single-crystal diamond anvils can sustain before failing — pushing laboratory static compression closer to the pressures found at Earth's core-mantle boundary.
The highest static (non-shock) pressure achieved and held between the tips of a laboratory diamond anvil cell, distinct from the transient pressures reached in dynamic shock-compression experiments.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
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.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
