What's the maximum gravity we could survive?

Thu, 09/20/2018 - 04:00
If we wish to colonize another world, finding a planet with a gravitational field that humans can survive and thrive under will be crucial. If its gravity is too strong our blood will be pulled down into our legs, our bones might break, and we could even be pinned helplessly to the ground. Finding the gravitational limit of the human body is something that’s better done before we land on a massive new planet. Now, in a paper published on the pre-print server arXiv, three physicists, claim

Although autumn arrives with the equinox this coming weekend, the famed Summer Triangle — a skywatcher warm weather favorite — remains prominent in the evening sky. Look high in the west after darkness falls and your eyes will fall on the brilliant star Vega in the constellation Lyra the Harp. At magnitude 0.0, Vega is the brightest member of the Triangle. The second-brightest star, magnitude 0.8 Altair in Aquila the Eagle, lies some 35° southeast of Vega. The asterism’s
