The search for a strategy for mankind to survive the solar Red Giant catastrophe

TL;DR

This paper explores a multi-stage strategy for Earth's survival against the Sun's evolution into a Red Giant, involving constructing a parasol, relocating Earth, and creating an artificial Sun using advanced fusion technology.

Contribution

It proposes a novel, comprehensive plan combining astrophysical engineering and fusion technology to ensure Earth's long-term survival through stellar evolution.

Findings

Design of a parasol at L1 to shade Earth

Feasibility of shifting Earth to the Kuiper Belt

Concept of an artificial Sun powered by fusion stations

Abstract

In around 5 gigayears our Sun will grow to a Red Giant and will swallow Earth. The plan is subdivided into two parts: We propose to construct some kind of parasol to shadow Earth. The position of the parasol will be the (inner) Lagrange Point L1. If we want to survive also the time beyond the next 5 Gy, where Suns luminosity and radius increase hundred fold and oscillate until our Sun develops finally into a White Dwarf, we have to shift Earth into the Kuiper Belt (50 AU) by means of the swing-by technique During this journey of about some megayears or more Earth must be illuminated by an artificial light source. A ring of DD-fusion power stations outstretched on Moons orbit should produce the necessary 175 PW of visible light. In the Kuiper Belt Earth will be brought into an orbit of an artificial Sun, an ArtSun formed in the meantime by the fusion of gaseous Jupiter-like planets imported from other planetary systems in the neighborhood
