A 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.
It is the hope of those who work toward the breakout from planet Earth that the establishment of permanent, self-sustaining colonies of humans off-Earth will ... make human life forever unkillable, removing it from the endangered species list, where it now stands on a fragile Earth overarmed with nuclear weapons. Second, the opening of virtually unlimited new land areas in space will reduce territorial pressures and therefore diminish warfare on Earth itself.
In time, [a Martian] colony would grow to the point of being self- sustaining. When this stage was reached, humanity would have a precious insurance policy against catastrophe at home. During the next millennium there is a significant chance that civilization on Earth will be destroyed by an asteroid, a killer plague or a global war. A Martian colony could keep the flame of civilization and culture alive until Earth could be reverse-colonized from Mars.
Economic localization is the key to sustaining biological and cultural diversity - to sustaining life itself. The sooner we shift towards the local, the sooner we will begin healing our planet, our communities and ourselves.
We stand on a great threshold in the human history of space exploration. If life is prevalent in our neighborhood of the galaxy, it is within our resources and technological reach to be the first generation in human history to finally cross this threshold, and to learn if there is life of any kind beyond Earth.
I don't know if it will be my big comeback, but I think it is a statement - that I am a self-sustaining, vibrant, long-term artist, and I'm not going away! And if you don't give me credit, then the musical gods will!
It is false to speak of realization. What is there to realize? The real is as it is always. We are not creating anything new or achieving something which we did not have before. The illustration given in books is this. We dig a well and create a huge pit. The space in the pit or well has not been created by us. We have just removed the earth which was filling the space there. The space was there then and is also there now. Similarly we have simply to throw out all the age-long sanskaras [innate tendencies] which are inside us. When all of them have been given up, the Self will shine alone.
Before the boiling of blood and the searing of skin comes the secret catastrophe: Before Life on Earth becomes finally merely impossible, it will for a long time before have become completely unbearable.
I'd like to be proven wrong firstly on the difficulty of building a self-sustaining closed circuit ecosystem in space that can support human life.
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. But if we end up going the life route instead of the death route, then in a distant future our cosmos will be teaming with life, all of which can be traced back to what we do-here and now. I don't know how we'll be thought of, but I'm sure that we won't be remembered as insignificant.
A silence is needed before death, before life, before love. If you love a person you sit silently with the person. You would not like to chatter, you would like to just hold their hand and live and be silent in that moment. If you chatter, that means you are avoiding the person - love is not really there. If you love life, chattering will drop, because every moment is so filled with life that there is no way, no space to chatter. Each moment life is flooding you so vitally - where is the time to gossip and chatter?
It really seems to me sometimes that the only hope is space. That is to say, perhaps the most energetic?in a bad sense?elements will move on to a new world in space. The problems of mass society will be transported into space, leaving behind this world as a kind of Europe, which then eventually tourists will visit. The Old World. I'm only half joking.
Mankind will not forever remain on Earth but, in the pursuit of light and space, will first timidly emerge from the bounds of the atmosphere and then advance until he has conquered the whole of circumsolar space.
And so, a prediction, and my heartfelt wish for you: as you get older, your self will diminish and you will grow in love. YOU will gradually be replaced by LOVE. If you have kids, that will be a huge moment in your process of self-diminishment. You really won't care what happens to YOU, as long as they benefit. That's one reason your parents are so proud and happy today. One of their fondest dreams has come true: you have accomplished something difficult and tangible that has enlarged you as a person and will make your life better, from here on in, forever.
Once we are self-aware, we must choose purposes and principles to live by; otherwise the vacuum will be filled, and we will lose our self-awareness and become like groveling animals who live primarily for survival and propagation. People who exist on that level aren't living; they are "being lived".
Perhaps future space probes will be plastered in commercial logos, just as Formula One cars are now. Perhaps Robot Wars in space will be a lucrative spectator sport. If humans venture back to the moon, and even beyond, they may carry commercial insignia rather than national flags.
In the future, it will not be the one big message, the one big voice, but millions of us, in our own way, healing, unifying, and experiencing that one defining moment when we recognize that sustaining the democracy is the common bottom line - whoever we are, whatever we do, wherever we are, the call is to sustain the democracy.
