Catastrophe Quote by Martin Rees
“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. . . . Will this happen before our technological civilization 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 forever? We live at what could be a defining moment for the cosmos.”

![“This brief century of ours is arguably the most significant one in the history of our universe. We'll have the technology either to self-destruct, or [to] seed our cosmos with life. The situation is so unstable that I doubt we can dwell at this fork in the road for more than another hundred years…” quote by Max Tegmark](https://sms4smile.com/quotes/img-quotes/df2/max-tegmark-3860_century_this-brief-century-of-ours-is-arguably-t_1957021.jpg)
