"Zarmina's World" -- Astronomer's Zeroing in On Habitable Extrasolars

[Khendraja'aro]

I'm thinking hybernation.

I'm half-tempted at this moment to calculate how long the actual trip would take at, say, 1G constant acceleration.

So, we have

v(T) = c tanh(a T/c)

which would mean that

s(T) = c²/a ln cosh(a T/c)

now we're solving the whole thing for T, since we want to know how long 10 lightyears at 1G will take

T = c/a cosh^-1 exp(sa/c²)

Setting c = 3E08 m/s, a = 10 m/s², and s = 10 ly = 9.461E16 m we get:

T = 2.4E23s = 7.8E12 a
("a" stands for "annum" or "years" in Latin for all you non-scientists :) )

In other words: Several eons (and that's only the acceleration phase! Halfway!). Unless my calculations are horribly wrong somewhere
