The question, scope, and sources behind this Registry record.
The Gran Telescopio Canarias, on the Canary Island of La Palma, Spain, has a segmented primary mirror 10.4 m in diameter and has been the largest operational single optical telescope in the world since it began operations in 2009.
The greatest primary mirror diameter of any ground-based optical telescope currently in operation. Larger telescopes (the 39 m Extremely Large Telescope and 25.4 m Giant Magellan Telescope) are under construction but not yet operational as of 2026.
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.
