Inspirational Astrophysics Quotes

In the beginning, nearly 14 billion years ago, all the space and all the matter and all the energy of the known universe was contained in a volume less than one-trillionth the size of the period that ends this sentence.

From that day on, I began to think of people not as the masters of space and time but as participants in a great cosmic chain of being, with a direct genetic link across species both living and extinct, extending back nearly four billion years to the earliest single-celled organisms on Earth.

Earth was the winner of the ultimate lotto, with 500 million to one odds, this one planet, of comparable, size to its other 17 billion siblings, became the life force of the universe itself. But the inhabitants of earth did not just inherit life, they inherited all that life has to offer a sentient species. It offers them —as a gift— love, joy, surprise, wonder, friendship, as well as spirituality, art, literature, music, and most importantly morality. A morality that is capable of reaching beyond its species to that of other living creatures on this shared fishbowl called Earth.

We use the effect of centrifugal forces on matter to offer insight into the rotation rate of extreme cosmic objects. Consider pulsars. With some rotating at upward of a thousand revolutions per second, we know that they cannot be made of household ingredients, or they would spin themselves apart. In fact, if a pulsar rotated any faster, say 4,500 revolutions per second, its equator would be moving at the speed of light, which tells you that this material is unlike any other. To picture a pulsar, imagine the mass of the Sun packed into a ball the size of Manhattan. If that’s hard to do, then maybe it’s easier if you imagine stuffing about a hundred million elephants into a Chapstick casing. To reach this density, you must compress all the empty space that atoms enjoy around their nucleus and among their orbiting electrons. Doing so will crush nearly all (negatively charged) electrons into (positively charged) protons, creating a ball of (neutrally charged) neutrons with a crazy-high surface gravity. Under such conditions, a neutron star’s mountain range needn’t be any taller than the thickness of a sheet of paper for you to exert more energy climbing it than a rock climber on Earth would exert ascending a three-thousand-mile-high cliff. In short, where gravity is high, the high places tend to fall, filling in the low places—a phenomenon that sounds almost biblical, in preparing the way for the Lord: “Every valley shall be raised up, every mountain and hill made low; the rough ground shall become level, the rugged places a plain” (Isaiah 40:4). That’s a recipe for a sphere if there ever was one. For all these reasons, we expect pulsars to be the most perfectly shaped spheres in the universe.

The little red dot of my rebirth, the Christ Consciousness, the vast galaxy within aching to be explored.

And maybe it had to do with all the murders lately, but death was on her mind and what she had so far in regard to her graduation talk was not exactly what you would call inspiring. Life in a nutshell: we’re born, we suffer, and then we die. Heartache and grief and loneliness chase us every day, the kind of love we long for is never quite within our reach, justice eludes us, and in the end, meaning is nothing but an illusion. After all, life is an anomaly, the exception, not the norm. Death is the natural state of affairs both here and everywhere else we know of in the universe—and it’s on its way to reasserting itself. All the evidence from evolutionary biology, astrophysics, astronomy, all the theorizing in statistics and probability make it clear there’s no possible way intelligent life exists anywhere else other than on earth. Any other view is either wishful thinking or a carefully cultivated blindness. Death is the default setting of the universe. The end of life on this planet would be the end of life everywhere. And that day is coming.

My hope is that evidence for the exquisite fine-tuning observed at all astronomical levels, from the farthest reaches of the cosmos to the ground beneath our feet, arouses a profound sense of awe and wonder. My greater hope is that this awe and wonder will inspire readers to ponder the deep questions raised by a close-up glimpse of nature's unfolding story.

[Stephen] Hawking’s contributions to the fields of cosmology and quantum mechanics are essentially unparalleled. His book “A Brief History of Time” is a wonderful window into these contributions as expressed by one of the deepest of thinkers and most powerful of educators. As Hawking’s muscle control continued to decay, he wrote entire books using just the muscle of his cheek to get the right letter, sometimes only faring as well as one or two words per minute. To anyone who has used an Apple TV remote, you know how wildly infuriating it is to even type out an entire YouTube title by scrolling through individual letters - now imagine writing an entire original book about astrophysics. Using your cheek. It honestly puts me to shame, as I struggle to challenge my old ways of writing music to find new ways to create. But Hawking showed that it is possible, through the heroic task of staring disability and obscurity in the face and typing out a loud and stunningly clear: “No.
