"To the Edge of the Universe in Under 50 Years" with constant acceleration and time dilation

Anton Pretrov examines “To the Edge of the Universe in Under 50 Years”?

The idea is a fuel supply that maintains constant acceleration of at least 1 g. The acceleration provides artificial gravity, which is better than a rotating cylinder. The longer it travels the more the time dilation.

So you can get to Mars in 30 days, to the middle of our galaxy in about 7 years your time , and the edge of the universe in 50 years (not allowing for space expansion). What you see ahead of you is blue-shifted and behind is red shifted.
This idea could allow selected astronauts to go very long distances to find another Earth when ours is uninhabitable – but who gets to go?
