Is dark matter in danger? A few days after scientists said there’s no dark matter near our sun, a team of researchers in Germany now says there’s no dark matter in our galactic neighborhood. The team found a vast structure of globular clusters and satellite galaxies surrounding the Milky Way in a smooth, evenly distributed [...]

Imagine: you’ve traveled all the way across the galaxy to some faraway, potentially life-embracing planet orbiting a faraway star, only to obliterate your destination upon arrival. It’s a very real threat according to few physicists at the University of Sydney. It turns out that a spacecraft emerging from a so-called Alcubierre warp drive does so [...]
