Overview
- An independent researcher, Gabriel Harry, has had a paper accepted by the Journal of the British Interplanetary Society that sketches a long-term survival strategy for Earth using solar‑system engineering.
- The plan calls for a vast thin sunshade placed near L1 and held by a carbon tether built from materials mined from the Moon and roughly 40% of Ceres to block the red‑giant Sun’s heat.
- To replace blocked sunlight the study proposes fusion reactors fed by hydrogen from Jupiter, sited deep in its atmosphere, with energy beamed to Earth as artificial sunlight.
- To avoid engulfment the proposal would gradually move Earth outward to about 1.2 AU by firing streams of material—oxygen mined from Jupiter—past the planet to change its momentum over eons.
- The paper also suggests sustaining tectonics by delivering antimatter into Earth’s interior, but media coverage and the author stress that all concepts are highly speculative and depend on technologies far beyond present capabilities and unresolved legal and safety questions.
