Timing is easy to predict through the movement of the stars as they give the propensity of pure potential.

One of the most striking results of modern investigation has been the way in which several different and quite independent lines of evidence indicate that a very great event occurred about two thousand million years ago. The radio-active evidence for the age of meteorites; and the estimated time for the tidal evolution of the Moon's orbit (though this is much rougher), all agree in their testimony, and, what is far more important, the red-shift in the nebulae indicates that this date is fundamental, not merely in the history of our system, but in that of the material universe as a whole.

My feeling is that an observer needs to see four hundred and fifty stars to get that feeling of infinitude, and be swept away…and I didn’t make that number up arbitrarily, that’s the number of stars that are available once you get dimmer than third magnitude. So in the city, you see a dozen stars, a handful, and it’s attractive to no one. And if there’s a hundred stars in the sky it still doesn’t do it. There’s a certain tipping point where people will look and there will be that planetarium view. And now you’re touching that ancient core, whether it’s collective memories or genetic memories, or something else form way back before we were even human…astronomer Bob Berman quoted in The End of Night

Some piously record 'In the beginning God', but I say 'In the beginning hydrogen'.

Sometimes he counts himself to sleep by imagining the miles between stars like the succession of footsteps cleaving him from his home, as if mastering the distance in thought might blunt the separation. But if a man cannot return to the place of his birth, then what is there to stay his restless feet? What center will hold him from wandering endlessly? It should not be so difficult, he thinks, to know one’s place in the order of things.

I’ve whittled my fascination with the cosmos down to this mantra: we can imagine the Universe as a giant void racing away from us at a frightening speed, or it could occur to us that, in fact, it is wrapped around us in all directions. Then, no matter where we are, we are at the centre of something wonderful. And that’s how I’ve always thought about it.

The near side of a galaxy is tens of thousands of light-years closer to us than the far side; thus we see the front as it was tens of thousands of years before the back. But typical events in galactic dynamics occupy tens of millions of years, so the error in thinking of an image of a galaxy as frozen in one moment of time is small.

High altitude astronomy is a strange world of oxygen starvation, sleep deprivation and radiation sickness.

The Universe was opaque until 380.000 years after the Big Bang.

The lifetime of a human being is measured by decades, the lifetime of the Sun is a hundred million times longer. Compared to a star, we are like mayflies, fleeting ephemeral creatures who live out their lives in the course of a single day.

When discharging industrial gas into the indoor environment in high altitude astronomy, we never wore breathing respirators that fed us oxygenated air at above the legally required 19.5% oxygen levels.

Medicine rests upon four pillars—philosophy, astronomy, alchemy, and ethics. The first pillar is the philosophical knowledge of earth and water; the second, astronomy, supplies its full understanding of that which is of fiery and airy nature; the third is an adequate explanation of the properties of all the four elements—that is to say, of the whole cosmos—and an introduction into the art of their transformations; and finally, the fourth shows the physician those virtues which must stay with him up until his death, and it should support and complete the three other pillars.

There are many arts and sciences of which a miner should not be ignorant. First there is Philosophy, that he may discern the origin, cause, and nature of subterranean things; for then he will be able to dig out the veins easily and advantageously, and to obtain more abundant results from his mining. Secondly there is Medicine, that he may be able to look after his diggers and other workman ... Thirdly follows astronomy, that he may know the divisions of the heavens and from them judge the directions of the veins. Fourthly, there is the science of Surveying that he may be able to estimate how deep a shaft should be sunk ... Fifthly, his knowledge of Arithmetical Science should be such that he may calculate the cost to be incurred in the machinery and the working of the mine. Sixthly, his learning must comprise Architecture, that he himself may construct the various machines and timber work required underground ... Next, he must have knowledge of Drawing, that he can draw plans of his machinery. Lastly, there is the Law, especially that dealing with metals, that he may claim his own rights, that he may undertake the duty of giving others his opinion on legal matters, that he may not take another man's property and so make trouble for himself, and that he may fulfil his obligations to others according to the law.

The others would then fall silent and she would continue about doped gallium arsenide detectors, or the ethanol content of the galactic cloud W-3. The quantity of 200-proof alcohol in this single interstellar cloud was more than enough to maintain the present population of the Earth, if every adult were a dedicated alcoholic, for the age of the solar system. The tamada had appreciated the remark.

When you organize extraordinary missions, you attract people of extraordinary talent who might not have been inspired by or attracted to the goal of saving the world from cancer or hunger or pestilence.

When I die, I will return to where I first came from. Back to the stars.

Wisdom tolerates blustered opinions, the better to dismiss them later with discovery.

I have realized; it is during the times I am far outside my element that I experience myself the most. That I see and feel who I really am, the most! I think that's what a comet is like, you see, a comet is born in the outer realms of the universe! But it's only when it ventures too close to our sun or to other stars that it releases the blazing "tail" behind it and shoots brazen through the heavens! And meteors become sucked into our atmosphere before they burst like firecrackers and realize that they're shooting stars! That's why I enjoy taking myself out of my own element, my own comfort zone, and hurling myself out into the unknown. Because it's during those scary moments, those unsure steps taken, that I am able to see that I'm like a comet hitting a new atmosphere: suddenly I illuminate magnificently and fire dusts begin to fall off of me! I discover a smile I didn't know I had, I uncover a feeling that I didn't know existed in me... I see myself. I'm a shooting star. A meteor shower. But I'm not going to die out. I guess I'm more like a comet then. I'm just going to keep on coming back.

I believe that this Nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to earth.

At every level in our inventory, nothing seems special about our Earth, our Sun, our Galaxy, our Local Group. Evidently, mediocrity reigns throughout. Such is our niche in the Universe.

My father, a Palestinian, and my mother, an Israeli, met in a bar in New York. Their encounter was a blue shift. An anomaly. A collision. In the end, I understand, it is only for this we live. All I ever wanted was to love.

Astronomy is, not without reason, regarded, by mankind, as the sublimest of the natural sciences. Its objects so frequently visible, and therefore familiar, being always remote and inaccessible, do not lose their dignity.

Man-eaters are finally shot dead.

An attempt to study the evolution of living organisms without reference to cytology would be as futile as an account of stellar evolution which ignored spectroscopy.

Let's grant that the stars are scattered through space, hither and yon. But how hither, and how yon? To the unaided eye the brightest stars are more than a hundred times brighter than the dimmest. So the dim ones are obviously a hundred times farther away from Earth, aren't they?Nope.That simple argument boldly assumes that all stars are intrinsically equally luminous, automatically making the near ones brighter than the far ones. Stars, however, come in a staggering range of luminosities, spanning ten orders of magnitude ten powers of ten. So the brightest stars are not necessarily the ones closest to Earth. In fact, most of the stars you see in the night sky are of the highly luminous variety, and they lie extraordinarily far away.If most of the stars we see are highly luminous, then surely those stars are common throughout the galaxy.Nope again.High-luminosity stars are the rarest. In any given volume of space, they're outnumbered by the low-luminosity stars a thousand to one. It's the prodigious energy output of high-luminosity stars that enables you to see them across such large volumes of space.

When I worked in high altitude astronomy, the worst sickness that I experienced was not at the 13,796 feet very high altitude summit of Mauna Kea Observatory (MKO) in Hawaii, it was at Kitt Peak National Observatory (KPNO) in Arizona at the much lower altitude of 6,875 feet. Due to my very high altitude experiences, I knew that this strange sickness was not primarily caused by altitude sickness and was most likely Sick Building Syndrome (SBS). After reporting various behavioral problems in all of the staff to the management team, my contract was not renewed, I was unable to legally protect the health and safety of the workers that I was responsible for, troubleshooting of this environmental problem stopped and I left in a sickened state for my next position before I could find the root cause.

n every culture, the sky and the religious impulse are intertwined. I lie back in an open field and the sky surrounds me. I’m overpowered by its scale. It’s so vast and so far away that my own insignificance becomes palpable. But I don’t feel rejected by the sky. I’m a part of it - tiny, to be sure, but everything is tiny compared to that overwhelming immensity. And when I concentrate in the stars, the planets, and their motions, I have an irresistible sense of machinery, clockwork, elegant precision working on a scale that, however lofty out aspirations, dwarfs and humbles us.

The biggest surprise that I had during my time in high altitude astronomy was being prevented from arranging a free Occupational Safety & Health Administration (OSHA) onsite evaluation to assist with bringing the observatory into OSHA compliance by the upper management team that I reported to.

The knowledge that the atoms that comprise life on earth - the atoms that make up the human body, are traceable to the crucibles that cooked light elements into heavy elements in their core under extreme temperatures and pressures. These stars- the high mass ones among them- went unstable in their later years- they collapsed and then exploded- scattering their enriched guts across the galaxy- guts made of carbon, nitrogen, oxygen, and all the fundamental ingredients of life itself. These ingredients become part of gas clouds that condense, collapse, form the next generation of solar systems- stars with orbiting planets. And those planets now have the ingredients for life itself. So that when I look up at the night sky, and I know that yes we are part of this universe, we are in this universe, but perhaps more important than both of those facts is that the universe is in us. When I reflect on that fact, I look up- many people feel small, cause their small and the universe is big. But I feel big because my atoms came from those stars.

ASTRO-GYMNASTICSGo on a starlit night, stand on your head,leave your feet dangling outwards into space,and let the starry firmament you treadbe, for the moment, your elected base.Feel Earth's colossal weight of ice and granite,of molten magma, water, iron, and lead;and briefly hold this strangely solid planetbalanced upon your strangely solid head.

[Giordano] Bruno died, despised and suffering, after eight years of agony. From that moment, his works have attracted interest, and he has long been recognized as an important figure in the development of modern thought. Nevertheless, few are familiar with the many and often bewildering pages of his writings. His Italian works have their place in the history of Italian literature. The Latin works in prose and verse are much more bulky and diffuse, but the few who grapple with them are rewarded by passages of great beauty and eloquence.

The same ratios that govern music give laws to optics and to the movement of the heavens as well. Simple. Elegant. Predictable.

Research suggests that sea level adapted humans that work at the very high altitude 13,796 feet summit of Mauna Kea may eventually develop sleep apnea and fatigue from the low oxygen environment.

And when you look at the sky you know you are looking at stars which are hundreds and thousands of light-years away from you. And some of the stars don’t even exist anymore because their light has taken so long to get to us that they are already dead, or they have exploded and collapsed into red dwarfs. And that makes you seem very small, and if you have difficult things in you life it is nice to think that they are what is called negligible, which means they are so small you don’t have to take them into account when you are calculating something.

Across the sea of space, the stars are other suns.

As the eclipse progresses, a confusion of chattering birds sweeps low in search of dusk and their shadows skip over the water’s surface and it makes perfect sense that these small creatures should be so moved by events beyond their reckoning.

At night the sky is pure astronomy.

After a decade of working in high altitude astronomy the medical profession discovered that I had a hole in my heart, erratic low blood oxygen levels and brain issues. Heart, lung and brain problems appear to be long term known adverse health aspects of high altitude work and unnatural electromagnetic radiation exposures.

The telescope, in enabling us to look far out into space, also allows us to look back in time. Light travels at about 186,000 miles per second. When we look up into the daylight sky, we are not seeing the sun as it currently is but as it was about eight minutes ago, since it takes that long for the light radiating from this familiar star to travel 93 million miles to Earth. Similarly, when the Giant Magellan Telescope (GMT) receives light waves from the depths of the universe, those waves will have originated from points as far as 76 sextillion (76,000,000,000,000,000,000,000) miles away. It will have taken those waves some 13 billion years to arrive on earth, meaning they left their source about a million years after the big bang, and roughly nine to ten billion years before Earth even formed.

The only way to go back in time is by moving into the future

Nothing in heaven or earth is content to be alone, and so there must always be something more. The universe is governed by a principle no more complicated than this: that a solitary body will forever attract another to itself.

One can only wonder what the motivation is for Mauna Kea astronomers to subject their nighttime support staff to extremely long and fatiguing night shifts when they are easily avoidable.

At the very moment that humans discovered the scale of the universe and found that their most unconstrained fancies were in fact dwarfed by the true dimensions of even the Milky Way Galaxy, they took steps that ensured that their descendants would be unable to see the stars at all. For a million years humans had grown up with a personal daily knowledge of the vault of heaven. In the last few thousand years they began building and emigrating to the cities. In the last few decades, a major fraction of the human population has abandoned a rustic way of life. As technology developed and the cities were polluted, the nights became starless. New generations grew to maturity wholly ignorant of the sky that had transfixed their ancestors and that had stimulated the modern age of science and technology. Without even noticing, just as astronomy entered a golden age most people cut themselves off from the sky, a cosmic isolationism that ended only with the dawn of space exploration.

Any patch of sunlight in a wood will show you something about the sun which you could never get from reading books on astronomy. These pure and spontaneous pleasures are ‘patches of Godlight’ in the woods of our experience.

When I worked in astronomy, I routinely observed young college and university students working with liquid nitrogen and breathing nitrogen gas as they discharged it into the indoor environment at high altitude.

If the Pentateuch is not inspired in its astronomy, geology, geography, history or philosophy, if it is not inspired concerning slavery, polygamy, war, law, religious or political liberty, or the rights of men, women and children, what is it inspired in, or about? The unity of God?—that was believed long before Moses was born. Special providence?—that has been the doctrine of ignorance in all ages. The rights of property?—theft was always a crime. The sacrifice of animals?—that was a custom thousands of years before a Jew existed. The sacredness of life?—there have always been laws against murder. The wickedness of perjury?—truthfulness has always been a virtue. The beauty of chastity?—the Pentateuch does not teach it. Thou shalt worship no other God?—that has been the burden of all religions.
