I'm writing a book about a civilization started by humans who sent a laser-powered sail ship with AIs and frozen embryos to the edge of the cosmological event horizon (the furthest we can travel before expansion of the universe disallows us to travel further). I want to be able to find possible real-life objects at a certain distance from earth that my ship would be able to travel to.
Things I'm assuming for the sake of my own sanity:
- There is a stable infinitely-working source of power driving the laser.
- This ship will be able to accelerate at a maximum of 100 Gs (~981 m/s2)
- This ship will be able to travel up to 30% of c, or the speed of light, (89937737.4 m/s)
- The ship leaves Earth in the "near future" from 2100-2200.
- Would embryos be able to survive 100Gs for so long? If not, what is a reasonable acceleration?
- Using the acceleration answered above, if the ship constantly accelerates up to 30% of c, coasts for an x amount of time, and then constantly decelerates until they stop at their final destination, what is the furthest they would be able to travel in lightyears from earth?
