From Universe Today, June 20, 2018: A Fermilab astrophysicist recently conducted a study that indicates how a sufficiently advanced civilization might be able to harvest Local Group stars and prevent them from expanding outward.
From Russia Today, June 21, 2018: Expansion of the universe, thought to be further accelerated by dark energy, is flinging matter apart, while galaxies are being pushed away from each other. This is a challenge alien technologies will have to deal with in order for them to survive, Fermilab’s Dan Hooper writes in a new study.
From Science News, June 19, 2018: Fermilab physicist Dan Hooper proposes that, to offset a future cosmic energy shortage caused by the accelerating expansion of the universe, a super-advanced civilization could pluck stars from other galaxies and bring them home. It’s a far-out idea, tackling a dilemma in a future so distant that human beings can hardly fathom it: 100 billion years from now, each neighborhood of the universe will be marooned as if on a cosmic island, with resources from the rest of the universe inaccessible.
From PBS’s NOVA Wonders, May 30, 2018: Fermilab’s Josh Frieman and Brian Nord appear in this episode on the dark sector.
From Nature, Sept. 5, 2017: Maps of the cosmic microwave background have become iconic representations of the early universe. But when the Dark Energy Survey collaboration unveiled the analysis of their first year of data last month, many felt that a new era had started.
