“Dying is something we human beings do continuously, not just at the end of our physical lives on this earth.”

Variant: Just as when we come into the world, when we die we are afraid of the unknown. But the fear is something from within us that has nothing to do with reality. Dying is like being born: just a change.

The Universe - Sex in Space (2008)

Context: For the most part we humans live with the false impression of security and a feeling of being at home in a seemingly trustworthy physical and human environment. But when the expected course of everyday life is interrupted, we are like shipwrecked people on a miserable plank in the open sea, having forgotten where they came from and not knowing whither they are drifting. But once we fully accept this, life becomes easier and there is no longer any disappointment.

Our Final Hour: A Scientist's Warning (2003) <!-- | date = 2003-03-18
Context: Once the threshold is crossed when there is a self-sustaining level of life in space, then life's long-range future will be secure irrespective of any of the risks on Earth (with the single exception of the catastrophic destruction of space itself). Will this happen before our technical civilisation disintegrates, leaving this as a might-have-been? Will the self-sustaining space communities be established before a catastrophe sets back the prospect of any such enterprise, perhaps foreclosing it for ever? We live at what could be a defining moment for the cosmos, not just for our Earth.
