Long-distance space travel, traveling at sub-light speeds, will require a way to make the journey with a crew of aging humans. While it’s possible to avoid some of that through time dilation (a quirk of physics that slows down time for anything that speeds up), humans wouldn’t save a large amount of time until the ship reaches 90% of the speed of light. Assuming we could build ships that can go that fast, we could cut aging in half. At 99.5% light speed, we would age at only ten percent relative to an observer at rest. The problem is physics. More…
