Prior remnant
Venus
A spent Earth-sized world
Earth-sized and spent. Ninety-two bars of carbon dioxide. A surface wiped a few hundred million years ago. Read as an ending, not a first draft.
What missions and papers show
Nearly Earth’s size and mass. 92-bar CO₂. Magellan mapped a volcanic lid and radar-bright tesserae. Plumes and rifts in the Beta–Atla–Themis region. No island arcs. No Emperor–Hawaii chain.
How this site reads it
This site reads Venus as a world that already finished a cycle: spent highlands in the tesserae, then later plains, rises, and rifts. A finished-cycle lid can still run plumes and crack.
What would kill this stage
If Venus never had oceans or continents, the spent-Earth reading comes off the table.
