I had the pleasure to discuss the breakthrough star shot mission with Peter Worden, former Director of the NASA Ames, in Nairobi this January. The project is planning to shoot a 5 g payload with laser beams to Alpha Centauri. It is a very small step, but exciting!

The Fermi paradox shows our ignorance about the universe, I am pretty sure we shouldn’t use it deductively.

While I agree with you that we will not travel among the stars as meat in a can, like represented in the science fiction books since the 50s , I am convinced that there is plenty of energy that we will be able to harness to go there through our robotic and AI envoys.

Philip, I totally disagree.

First, at this moment "we have absolutely no idea how to use" this and that as you say, but we'll find out. Remember those respected physicists at the end of the 19th century who proclaimed that physics was done and finished, only a few years before Planck and Einstein. There are more things in heaven and earth, and we'll unveil them gradually. "Impossible" is a dirty word in my book.

Second, I see space expansion, first to the planets and then to the stars (yes, the stars), as a cosmic existential imperative. It is a duty, and we must (and will) find out how to do it.

Third, WTF is wrong with expanding into space AND making the Earth work?
