I need to correct myself and point out that the values I got were wrong. Formulae: t' = (c / g) * asinh(gt/c) - time measured by ship's crew Numerical values: g = 9.81 m/s² x = 4.3 ly = 4.07E16 m Time from the perspective of people on Earth (t): 1.63E8 seconds = 5.18 years. Time from the perspective of people on the ship (t'): 7.27E7 seconds = 2.31 years. Derivation was OK, had four other people check it for me and can show the work. It's not a new result anyway. Regardless, sorry for the mistake. am_Unition, ButterflyEffect, nil - you also shared that post, so I'm shouting out just in case it has any relevance for you guys. t = sqrt(x²/c² + 2x/g) - time measured on Earth c = 3.00E8 m/s
