Some astrophysicists have convinced themselves that the fifth significant figure of the fine structure constant has changed over the past ten billion years.

Today every city, town, or village is affected by it. We have entered the Neon Civilization and become a plastic world.. It goes deeper than its visual manifestations, it affects moral matters; we are engaged, as astrophysicists would say, on a decaying orbit.

He was a physicist, more precisely an astrophysicist, diligent and eager but without illusions: the Truth lay beyond, inaccessible to our telescopes, accessible to the initiates. This was a long road which he was traveling with effort, wonderment, and profound joy. Physics was prose: elegant gymnastics for the mind, mirror of Creation, the key to man's dominion over the planet; but what is the stature of Creation, of man and the planet? His road was long and he had barely started up it, but I was his disciple: did I want to follow him?

Don't most astrophysicists now predict some "end of the line" - an end to it all? Not just the death of things, but the annihilation of everything. Some great contraction, or collapse. Or, perhaps, some vast dissipation into eternal emptiness. Maybe it's all swallowed up by an immense black hole, which then swallows itself. But, whatever the case, their extinction is inevitable and absolute. So complete as to erase any and all evidence that this reality - this existence - ever took place. So complete that, perhaps, for all intents and purposes, it never really did. (attrib: F.L. Vanderson)

Right now there's a commonly-held view among scientists that we know about only four percent of all the matter in the universe. Four percent!""So what about the other 96 percent?""We astrophysicists call it 'dark matter' and 'dark energy.' Maybe we should just call it ignorance. There's so much that we don't know. It's shocking how little we know. And yet we behave like little gods who think we're in control of everything. Like kids with delusions of grandeur. Isn't that what we've made ourselves into? It's as if we're trying to make ourselves believe that four percent is all there is. That everything else, all that we don't know, doesn't exist. But it does. We know it's there; we just don't understand it.

Discovery first flew in 1984, the third orbiter to join the fleet. It was named for one of the ships commanded by Captain James Cook. Space shuttle Discovery is the most-flown orbiter; today will be its thirty-ninth and final launch. By the end of this mission, it will have flown a total of 365 days in space, making it the most well traveled spacecraft in history. Discovery was the first orbiter to carry a Russian cosmonaut and the first to visit the Russian space station Mir. On that flight, in 1995, Eileen Collins became the first woman to pilot an American spacecraft. Discovery flew twelve of the thirty-eight missions to assemble the International Space Station, and it was responsible for deploying the Hubble Space Telescope in 1990. This was perhaps the most far reaching accomplishment of the shuttle program, as Hubble has been called the most important telescope in history and one of the most significant scientific instruments ever invented. It has allowed astronomers to determine the age of the universe, postulate how galaxies form, and confirm the existence of dark energy, among many other discoveries. Astronomers and astrophysicists, when they are asked about the significance of Hubble, will simply say that it has rewritten the astronomy books. In the retirement process, Discovery will be the “vehicle of record,” being kept as intact as possible for future study.Discovery was the return-to-flight orbiter after the loss of Challenger and then again after the loss of Columbia. To me, this gives it a certain feeling of bravery and hope. ‘Don’t worry,’ Discovery seemed to tell us by gamely rolling her snow-white self out to the launchpad. 'Don’t worry, we can still dream of space. We can still leave the earth.’ And then she did.

Dinosaurs are extinct today because they lacked opposable thumbs and the brainpower to build a space program.

...people taking the time and energy to ask about what they do not understand - I have renewed hope that society can shed its superstitions and embrace the enlightenment that comes from just a basic understanding of how the universe works.

I am convinced that the act of thinking logically cannot possibly be natural to the human mind. If it were, then mathematics would be everybody's easiest course at school and our species would not have taken several millennia to figure out the scientific method.
