Black Holes & SingularitiesSwap the Sun for a black hole of the same mass and Earth’s orbit wouldn’t twitch — but with the light gone, our planet would freeze solid within months.
Terraforming & Sci-TechFrom super-greenhouse gases to an artificial magnetosphere, here is the actual engineering sequence scientists have proposed to make Mars habitable — and how long each step would take.
Cosmic MysteriesIn 1960, Freeman Dyson described how to find giant alien civilizations: look for the waste heat of star-sized machines. Sixty-six years later, astronomers are still looking — and the hunt just got interesting.
Black Holes & SingularitiesFrom the 4-million-solar-mass heart of our galaxy to a 100-billion-solar-mass monster that strains physics itself — a tour of the heavyweight champions of the cosmos.
Cosmic MysteriesThe galaxy should be crawling with civilizations. Seventy-five years after Enrico Fermi asked the question over lunch, the silence is still deafening — and the possible answers keep getting stranger.
