- laxd 2y agoIf we managed to build the ship and if we managed to get it to same speed as our fastest space probe, it would take around 35000 years.

- bradly 2y agoAt 99% the speed of light it will take the traveler less than three years, while 20 years passes on earth. If they then turn around they will return to earth, they will arrive aged 6 years while 40 years have passed on earth. You can come back younger than your children.
- jedberg 2y agoWhich then makes for an interesting moral or ethical dilemma: is it ok to embark on such a mission after having children, knowing that they will live half a lifetime without you and, assuming you left before the age of 34, will be older than you when you get back.
