Does it mean, if you don’t understand something, and the community of — Neil deGrasse Tyson

"A few years ago I got a phone call from a marketing executive who wanted to light up the Moon with the logo of her company. She wanted to know how she might proceed. After slamming down the phone, I called her back and politely explained why it was a bad idea. Other corporate executives have asked me how to put into orbit mile-wide luminous banners with catchy slogans written across them, much like the skywriting or flag-dragging airplanes you see at sports events or over the ocean from a crowded beach. I always threaten to send the light police after them."

"Life is too short for me to worry about something I have no control over that I don’t even know will happen. People ask ‘if Earth is going to be swallowed by a black hole or if there is some disturbance in the spacetime continuum should we worry about it?’. My answer is ‘no’ because you won’t know about it until it crosses your... your place in space-time. Your beats come to you when nature decides it’s the right time... be it the speed of sound, the speed of light, the speed of electrical impulses we will forever be victims of the time delay between information around us and our capacity to receive it."

"There are street artists. Street musicians. Street actors. But there are no street physicists. A little known secret is that a physicist is one of the most employable people in the marketplace - a physicist is a trained problem solver. How many times have you heard a person in a workplace say, "I wasnt trained for this!" Thats an impossible reaction from a physicist, who would say, instead, "Cool. A problem Ive never seen before. Lets see how I can figure out how to solve it!" Oh, and, have fun along the way."

"Other unrelenting skeptics might declare that “seeing is believing”—an approach to life that works well in many endeavors, including mechanical engineering, fishing, and perhaps dating. It’s also good, apparently, for residents of Missouri. But it doesn’t make for good science. 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 anatomy of a sound bite is—its gotta be interesting. And its gotta be tasty. It should also be a little bit fun to hear ... so that you smile. And its gotta have enough of all that to want to tell someone else that you just learned something. ... I have a master class on thinking like a scientist and how to communicate what you know in your expertise to others."

"The problem, often not discovered until late in life, is that when you look for things like love, meaning, motivation, it implies they are sitting behind a tree or under a rock. The most successful people recognize, that in life they create their own love, they manufacture their own meaning, they generate their own motivation. For me, I am driven by two main philosophies, know more today about the world than I knew yesterday. And along the way, lessen the suffering of others. Youd be surprised how far that gets you."
