Astronomy Quote by Raymond T. Pierrehumbert

““It is triste to contemplate the winding down of the Universe into a cold, dark, lonely place, but we are a young species in a young Universe, with vast reaches of time before us. It is certainly true that there are countless worlds out there that could support life as we know it, and probably countless more that could support life as we don’t know it. It may be that the Universe is teeming with life waiting to make our acquaintance. Or, we may well be the first ones in our galaxy to make the leap to sentience. The vast distance between stars poses a severe barrier to individuals or even societies making the journey. Protoplasm is just too fragile and short-lived a medium to be up to the task of such voyaging. However, at a tenth the speed of light, the whole galaxy can be traversed in a million years. That’s a long time for protoplasm, but it is not a stretch to think of the data that makes us what we are—embodied perhaps in silicon or some other sturdy information-bearing material and reconstituted at destination—spreading throughout the galaxy, hopping from planet to planet along the way like Pacific Islanders in their canoes. If life—or complex life—is rare, it may well be our destiny to seed the Universe with an expanding wave of consciousness. But it is to be hoped that we will leave abundant worlds alone to develop their own destinies. There are worlds enough, and time.””
