Limits RegistryPUBLIC RECORD
Limits RegistryCERN's tape-based archive, which stores the bulk of the data generated by the Large Hadron Collider's particle-physics experiments for long-term, cost-effective retention, surpassed 1 exabyte of stored data around 2023-2024, according to CERN's own IT department reporting, making it one of the largest single scientific tape archives in the world. Tape remains CERN's preferred medium for this scale of long-term archival storage because of its low cost per terabyte and long shelf life relative to spinning disk.

Tape remains CERN's preferred medium for this scale of long-term archival storage because of its low cost per terabyte and long shelf life relative to spinning disk.
The total volume of physics data stored on magnetic tape in CERN's long-term archive, primarily generated by the Large Hadron Collider's particle-detector 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.
