Astrophysics Quotes

“In the beginning, there was physics. "Physics" describes how matter, energy, space, and time behave and interact with one another. The interplay of these characters in our cosmic drama underlies all biological and chemical phenomena. Hence everything fundamental and familiar to us earthlings begins with, and rests upon, the laws of physics. When we apply these laws to astronomical settings, we deal with physics writ large, which we call astrophysics.”

“People who believe they are ignorant of nothing have neither looked for, nor stumbled upon, the boundary between what is known and unknown in the universe.”

“We are stardust brought to life, then empowered by the universe to figure itself out—and we have only just begun.”

“The gravitational waves of the first detection were generated by a collision of black holes in a galaxy 1.3 billion light-years away, and at a time when Earth was teeming with simple, single-celled organisms. While the ripple moved through space in all directions, Earth would, after another 800 million years, evolve complex life, including flowers and dinosaurs and flying creatures, as well as a branch of vertebrates called mammals. Among the mammals, a sub-branch would evolve frontal lobes and complex thought to accompany them. We call them primates. A single branch of these primates would develop a genetic mutation that allowed speech, and that branch—Homo Sapiens—would invent agriculture and civilization and philosophy and art and science. All in the last ten thousand years. Ultimately, one of its twentieth-century scientists would invent relativity out of his head, and predict the existence of gravitational waves. A century later, technology capable of seeing these waves would finally catch up with the prediction, just days before that gravity wave, which had been traveling for 1.3 billion years, washed over Earth and was detected.Yes, Einstein was a badass.”

“Same as you, Arthur. I hitched a ride. After all, with a degree in maths and another in astrophysics it was either that or back to the dole queue on Monday. Sorry I missed the Wednesday lunch date, but I was in a black hole all morning.”

“Carl Sagan spoke fluently between biology and geology and astrophysics and physics. If you move fluently across those boundaries, you realize that science is everywhere; science is not something you can step around or sweep under the rug.”

“The most accessible field in science, from the point of view of language, is astrophysics. What do you call spots on the sun? Sunspots. Regions of space you fall into and you don’t come out of? Black holes. Big red stars? Red giants. So I take my fellow scientists to task. He’ll use his word, and if I understand it, I’ll say, “Oh, does that mean da-da-da-de-da?”

“Historically, discoveries of pure science are slow to reach the mainstream compared with those of the applied sciences, which noisily announce themselves with new medicines and gadgets. The Hubble has proved an exception, remaking, in a single generation, the popular conception of the universe. It has accomplished this primarily through the aesthetic force of its discoveries, which distill the difficult abstractions of astrophysics into singular expressions of color and light, vindicating Keats’s famous couplet: “Beauty is truth, truth beauty.” Though philosophy has hardly registered it, the Hubble has given us nothing less than an ontological awakening, a forceful reckoning with what is. The telescope compels the mind to contemplate space and time on a scale just shy of the infinite.”

“If you put it as 'complex nervous systems' it sounds pretty deflationary. What's so special about a complex nervous system? But of course, that complex nervous system allows you to do calculus. It allows you to do astrophysics… to write poetry... to fall in love. Put under that description, when asked 'What’s so special about humans...?', I’m at a loss to know how to answer that question. If you don’t see why we’d be special… because we can do poetry [and] think philosophical thoughts [and] we can think about the morality of our behavior, I’m not sure what kind of answer could possibly satisfy you at that point....I could pose the same kinds of questions of you... So God says, 'You are guys are really, really special.' How does his saying it make us special? 'But you see, he gave us a soul.' How does our having a soul make us special? Whatever answer you give, you could always say… 'What’s so special about that?”
