Neil deGrasse Tyson 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.

Some of the greatest poetry is revealing to the reader the beauty in something that was so simple you had taken it for granted.

If you ask people where they're from, they will typically say the name of the city where they were born, or perhaps the place on Earth's surface where they spent their formative years. Nothing wrong with that. But an astrochemically richer answer might be, "I hail from the explosive jetsam of a multitude of high-mass stars that died more than 5 billion years ago.

Not enough books focus on how a culture responds to radically new ideas or discovery. Especially in the biography genre, they tend to focus on all the sordid details in the life of the person who made the discovery. I find this path to be voyeuristic but not enlightening. Instead, I ask, After evolution was discovered, how did religion and society respond? After cities were electrified, how did daily life change? After the airplane could fly from one country to another, how did commerce or warfare change? After we walked on the Moon, how differently did we view Earth? My larger understanding of people, places and things derives primarily from stories surrounding questions such as those.

Science literacy is being plugged into the forces that power the universe. There is no excuse for thinking that the Sun, which is a million times the size of Earth, orbits Earth.

To learn that it's easier to be told by others what to think and believe than it is to think for yourself.

On Friday the 13th of April 2029, an asteroid large enough to fill the Rose Bowl as though it were an egg cup, will fly so close to Earth, that it will dip below the altitude of our communication satellites. We did not name this asteroid Bambi. Instead, it's named Apophis, after the Egyptian god of darkness and death. If the trajectory of Apophis at close approach passes within a narrow range of altitudes called the 'keyhole,' the precise influence of Earth's gravity on its orbit will guarantee that seven years later in 2036, on its next time around, the asteroid will hit Earth directly, slamming in the Pacific Ocean between California and Hawaii. The tsunami it creates will wipe out the entire west coast of North America, bury Hawaii, and devastate all the land masses of the Pacific Rim. If Apophis misses the keyhole in 2029, then, of course, we have nothing to worry about in 2036.

Dinosaurs are extinct today because they lacked opposable thumbs and the brainpower to build a space program.
