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.
Looking more closely at Earth’s atmospheric fingerprints, human biomarkers will also include sulfuric, carbonic, and nitric acids, and other components of smog from the burning of fossil fuels. If the curious aliens happen to be socially, culturally, and technologically more advanced than we are, then they will surely interpret these biomarkers as convincing evidence for the absence of intelligent life on Earth.
Yes, Einstein was a badass.
In other words, after the laws of physics, everything else is opinion.
Science is not just about seeing, it’s about measuring, preferably with something that’s not your own eyes, which are inextricably conjoined with the baggage of your brain. That baggage is more often than not a satchel of preconceived ideas, post-conceived notions, and outright bias.
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?
The cosmic perspective shows Earth to be a mote. But it’s a precious mote and, for the moment, it’s the only home we have.
Robots are important also. If I don my pure-scientist hat, I would say just send robots; I’ll stay down here and get the data. But nobody’s ever given a parade for a robot. Nobody’s ever named a high school after a robot. So when I don my public-educator hat, I have to recognize the elements of exploration that excite people. It’s not only the discoveries and the beautiful photos that come down from the heavens; it’s the vicarious participation in discovery itself.
One of the great challenges in life is knowing enough to think you’re right but not enough to know you’re wrong.
Without a doubt, the most spectacular way to die in space is to fall into a black hole.
The moment when someone attaches you to a philosophy or a movement, then they assign all the baggage and all the rest of the philosophy that goes with it to you. And when you want to have a conversation, they will assert that they already know everything important there is to know about you because of that association. And that’s not the way to have a conversation.
Yes, not only humans but also every other organism in the cosmos, as well as the planets or moons on which they thrive, would not exist but for the wreckage of spent stars. So you’re made of detritus. Get over it. Or better yet, celebrate it. After all, what nobler thought can one cherish than that the universe lives within us all?
There’s no shame in admitting what you don’t know. The only shame is pretending you know all the answers.
The power and beauty of physical laws is that they apply everywhere, whether or not you choose to believe in them.
It is the destiny of stars to collapse.
Time to get cosmic. There are more stars in the universe than grains of sand on any beach, more stars than seconds have passed since Earth formed, more stars than words and sounds ever uttered by all the humans who ever lived.
The cosmic perspective opens our minds to extraordinary ideas but does not leave them so open that our brains spill out, making us susceptible to believing anything we’re told. The.
The universe has never made one of anything, so why would there even be one of itself?
If a huge genetic gap separated us from our closest relative in the animal kingdom, we could justifiably celebrate our brilliance. We might be entitled to walk around thinking we’re distant and distinct from our fellow creatures. But no such gap exists. Instead, we are one with the rest of nature, fitting neither above nor below, but within.
Nonetheless, they remind us that ignorance is the natural state of mind for a research scientist.
