Explanation / Answer

They're sharing a drink they call loneliness But it's better than drinking alone The spaceship is travelling at a speed of 0.846c or 0.846*speed oflight. Barnard's Star is 5.98 lightyears away.. it takes 5.98 years forlight to reach it. Our vessel can only move at a speed of 0.846*speed of light So it will take 5.98/.846 = 7.0685 years to reach Barnard's Star
