Why Space Gets More Horrifying the Further You Travel

The further you travel from Earth, the more hostile the universe becomes. At Mars, communication delays stretch to 24 minutes—no help can ever arrive. At the outer planets, it's hours. The Bootes Void, a region 330 million light-years across, contains almost nothing—a cosmic scar of pure emptiness. Black holes warp time and swallow light. Neutron stars spin hundreds of times per second, their gravity so intense that a teaspoon weighs a billion tons. The universe is trying to kill you.
