SUMMARY
To travel to the Pleiades, located 130 parsecs away, in 10 onboard years, a spacecraft must achieve a velocity expressed as a fraction of the speed of light (v/c). The relationship between time experienced onboard and the distance traveled is governed by the time dilation equation, ΔT = γΔT₀, where γ (gamma) represents the Lorentz factor. The onboard observer perceives the distance contracted due to relativistic effects, necessitating the use of the length contraction formula to determine the effective distance. Accurate calculations require understanding of both time dilation and length contraction principles in special relativity.
