Submission + - Interstellar travel was almost possible, 70k years ago... (eurekalert.org)
mrthoughtful writes: According to the bods at the University of Rochester, 70,000 years ago, a recently discovered dim star (Scholz's star) passed through our Oort cloud, in a near collision with Sol only 52,000 AU distant. Although this is still quite a distance, it is far closer than Proxima Centauri's current 266,000 AU, but still a stretch for Voyager I's 125 AU. Still, maybe the best way to engage in interstellar travel is just to wait until the time is right.
