Ирээдүйн иргэншил Нарны хөгжлийн сүүлчийн шатанд Дэлхийн амьдрах орчныг хадгалах боломжтой сансрын томоохон байгууламжуудын төслийг боловсруулжээ.
Нар ойролцоогоор нэг тэрбум жилийн дараа түлшээ шавхан улаан аварга од болон тэлэх төлөвтэй байна. Энэ үйл явц нь Дэлхийн уур амьсгал болон далай тэнгисийг устгаж, улмаар гаригийг залгих аюултай тул Габриел Харрийн хийсэн судалгаанд Дэлхийг нүүлгэн шилжүүлэхийн оронд сансрын инженерийн аргаар хамгаалах боломжийг авч үзжээ. “Journal of the British Interplanetary Society”-д нийтлэгдсэн уг судалгаанд нарны гэрлийг хаах асар том бамбайг Лагранжийн L1 цэгт байрлуулах санааг дэвшүүлсэн байна.
Энэхүү бамбайг барихад шаардлагатай нүүрстөрөгч болон хөнгөн цагааныг Церера астероид болон Сарны гадаргуугаас олборлох боломжтой гэж тооцоолжээ. Нарны хэт их халалтаас хамгаалахын зэрэгцээ Дэлхийг эрчим хүчээр хангахын тулд Бархасбадь гаригийн устөрөгч, гелийг ашиглан хиймэл гэрэл үүсгэх технологи шаардлагатай болно. Судлаачид Бархасбадийн агаар мандалд хайлуулах урвалын реакторуудыг байрлуулж, лазерын тусламжтайгаар Дэлхий рүү эрчим хүч дамжуулах боломжтой гэж үзэж байна.
Түүнчлэн, Нарны тэлэлтээс зайлсхийхийн тулд Дэлхийн тойрог замыг аажмаар холдуулах таталцлын дүүжин эффектийг ашиглах хувилбарыг судалжээ. Мөн гаригийн дотоод бүтцийн идэвхжлийг хадгалахын тулд антиматерийг ашиглах, цаашлаад Сүүн зам болон Андромеда галактикуудын мөргөлдөөний үед Нарны аймгийн байршлыг тохируулах зэрэг онолын шийдлүүдийг дэвшүүлсэн байна. Эдгээр санаа нь одоогийн технологийн хүчин чадлаас хол давсан хэдий ч дэвшилтэт иргэншлийн хувьд урт хугацааны шийдэл байж болох юм.

What if humanity did not have to leave Earth when the sun begins to die? A new study explores a scenario in which giant space structures, artificial light and planetary engineering could keep Earth habitable long after major changes affect the star at the center of our solar system.
The sun is expected to run out of fuel in about one billion years and become a red giant, a phase that would make Earth’s current environment impossible for life. The oceans and atmosphere would eventually disappear, and the planet could even be engulfed by the expanding star.
According to research by Gabriel Harry, accepted for publication in the Journal of the British Interplanetary Society, a future civilization could try to protect Earth instead of searching for another planet. The study describes a series of enormous engineering projects based on resources available within the solar system.
A Giant Shield Could Protect Earth From The Expanding Sun
The first challenge would be dealing with the increasing heat produced by the sun during its red giant phase. The study proposes building a massive sunshade and placing it at the Lagrange point 1 (L1), a region between Earth and the sun where gravitational forces are balanced.
According to the research, the shield would need to cover a large part of the sky to block the light from the expanded sun. To reduce the size required, the concept uses a counterweight connected to a long cable, allowing the sunshade to operate closer to Earth, just beyond the moon’s orbit.
The materials needed for this structure would come from nearby space objects. The study estimates that mining around 40% of Ceres could provide enough carbon to build a 2-million-kilometer tether. A small amount of lunar material, around 0.01% of the moon, could provide aluminum for a sunshade with a radius of 350,000 kilometers.
The shield would protect Earth from the worst effects of the red giant phase, but it would also block the sunlight that currently powers the planet. A replacement energy source would therefore be required.
Jupiter’s Energy Could Power Artificial Sunlight
The study proposes using gas giants as long-term energy sources. Jupiter, with its enormous quantities of hydrogen and helium, could provide the fuel needed for future fusion systems.
As explained by Gabriel Harry’s research, fusion reactors placed around 6,500 kilometers deep inside Jupiter’s atmosphere could use the planet’s natural pressure to help contain the reaction. The energy produced could then be transmitted toward Earth.
The proposed system would rely on space relays and powerful lasers to send artificial sunlight to the planet. One part of the concept includes a laser measuring around 15 kilometers that would transfer energy from a relay station to Earth’s surface.
The study estimates that Jupiter’s fusion resources could provide artificial sunlight for around 9.1 quadrillion years. The concept requires technologies far beyond current capabilities, but it presents Jupiter as a possible long-term energy source for an advanced civilization.
Could Earth Be Moved to Stay Habitable?
Even with a protective shield and artificial sunlight, Earth would face another challenge: the expanding sun could eventually threaten the planet’s orbit. The study examines ways to gradually move Earth farther away using the gravitational slingshot effect. One possibility would involve repeatedly sending objects close to Earth to transfer energy and slowly increase the planet’s orbital distance.
Another approach would use oxygen extracted from Jupiter and launched past Earth as a particle beam. As reported by the researchers, this beam would have a mass equivalent to half of the Amazon River’s outflow. If it accidentally reached Earth, the oxygen would spread through the atmosphere and would not create a major environmental threat.
The study also looks at how to maintain Earth’s internal activity. As tectonic processes slow down over time, the planet’s natural nutrient recycling would be affected. The proposed solution involves using antimatter placed inside containers and delivered into Earth’s interior with molten iron.
The research estimates that producing and delivering 2 kilograms of antimatter per day could maintain Earth’s tectonic activity. It also considers the future Milky Way–Andromeda merger, suggesting that hydrogen beams launched near Jupiter could help adjust the solar system’s position.
