Neil deGrasse Tyson _ Astrophysics for People in a
The Hubble Space Telescope has spotted aurora near the poles of both Saturn and Jupiter. And on Earth, the aurora borealis and australis {the northern and southern lights} serve as intermittent reminders of how nice it is to have a protective atmosphere.

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 billion elephants into a Chapstick casing.

Neil deGrasse Tyson _ Death by Black Hole
The easy part is the ray's 500-second speed-of-light jaunt from the Sun to Earth, through the void of interplanetary space. The hard part is the light's million-year adventure to get from the Sun's center to its surface.

Neil deGrasse Tyson _ Death by Black Hole
What are the chances that this first and only smart species in the history of life on Earth has enough smarts to completely figure out how the universe works? Chimpanzees are an evolutionary hair's-width from us yet we can agree that no amount of tutelage will ever leave a chimp fluent in trigonometry. Now imagine a species on Earth, or anywhere else, as smart compared with humans as humans are compared with chimpanzees. How much of the universe might they figure out?

Neil deGrasse Tyson _ Death by Black Hole
Perhaps these ancient observatories perennially impress modern people because modern people have no idea how the Sun, Moon, or stars move.

But a truly mysterious civilization would be one that made no cultural or architectural reference to the sky at all.

Neil deGrasse Tyson _ Death by Black Hole: And Other
Knowledge of physical laws can, in some cases, give you the confidence to confront surly people. A few years ago I was having a hot-cocoa nightcap at a dessert shop in Pasadena, California. I had ordered it with whipped cream, of course. When it arrived at the table, I saw no trace of the stuff. After I told the waiter that my cocoa was plain, he asserted I couldn't see the whipped cream because it sank to the bottom. Since whipped cream has a very low density and floats on all liquids that humans consume, I offered the waiter two possible explanations: either somebody forgot to add the whipped cream to my hot cocoa or the universal laws of physics were different in his restaurant. Unconvinced, he brought over a dollop of whipped cream to test for himself. After bobbing once or twice in my cup, the whipped cream sat up straight and afloat. What better proof do you need of the universality of physical laws?
