Et livssyn

Carl Sagan var en eminent forsker der formåede at gøre videnskab tilgængelig for alverdens lægfolk. I 1994 skrev han bogen “Pale Blue Dot” på bagrund af et billede af samme navn. Det var et billede af jorden taget fra rummet, hvor jorden dog ikke udgjorde mere end et lille ubetydeligt punkt. Jeg vil egentlig bare lade ordet være Carl Sagans ved denne lille video redigeret af en person fra en andet sted på denne lille ubetydelige prik. Teksten kan også forefindes nedenfor. God fornøjelse:


“The spacecraft was a long way from home. I thought it would be a good idea, just after Saturn, to have them take one last glance homeward. From Saturn, the Earth would appear too small for Voyager to make out any detail. Our planet would be just a point of light, a lonely pixel hardly distinguishable from the many other points of light Voyager would see: nearby planets, far off suns. But precisely because of the obscurity of our world thus revealed, such a picture might be worth having.” “It had been well understood by the scientists and philosophers of classical antiquity that the Earth was a mere point in a vast, encompassing cosmos — but no one had ever seen it as such. Here was our first chance, and perhaps also our last for decades to come”.

“So, here they are: a mosaic of squares laid down on top of the planets in a background smattering of more distant stars. Because of the reflection of sunlight off the spacecraft, the Earth seems to be sitting in a beam of light, as if there were some special significance to this small world; but it’s just an accident of geometry and optics. There is no sign of humans in this picture: not our reworking of the Earth’s surface; not our machines; not ourselves. From this vantage point, our obsession with nationalism is nowhere in evidence. We are too small. On the scale of worlds, humans are inconsequential: a thin film of life on an obscure and solitary lump of rock and metal.”

“Consider again that dot That’s here. That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every “supreme leader”, every “superstar”, every saint and sinner in the history of our species lived there – on a mote of dust suspended in a sunbeam.

The Earth is a very small stage in a vast cosmic arena. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot.

Our posturing, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves.

(The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet) Like it or not, for the moment the Earth is where we make our stand.

It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. And the score is our responsibility to deal more kindly with one another, and to preserve and cherish the only home we’ve ever known, the pale blue dot.”

The End!

Jeg har personligt et håb for fremtidens generationer.

  1. Hmm, lidt flovt at man ikke har læst mere Sagan…

  2. Det er der ingen grund til at være 🙂 Men jeg kan da godt anbefale ham, om end som det er med videnskab, at nogen ting kan blive mere eller mindre uddateret. Jeg synes det er væsentligt med disse personligheder der søger at skabe en bro mellem fagfolkene og os lægfolk og gøre den videnskabelige udvikling og tankegang tilgængelig for et bredere publikum. Som fine danske eksempler kan man jo nævne Tor Nørretanders og Lone Frank. Og så var han, Sagan, jo en generelt skeptisk indstillet, hvilket tiltaler mig. Men håber du kunne lide det 🙂
