So while you're getting ripped apart head to toe as you fall into a black hole, you will also extrude through the fabric of space and time, like toothpaste squeezed through a tube. To all the words in the English language that describe ways to die (e.g., homicide, suicide, electrocution, suffocation, starvation) we add the term spaghettification.

I would expunge the word "aptitude" from our vocabulary, because if you're interested in something, that's all that matters. You'll spend more time doing it, that than anything else, and possibly more time doing it than anybody else. And that's all that matters, because in the end, if you love what you do, you'll be your best at it compared to anything else you might have chosen as a career.

Many people feel small because they're small and the universe is big, but I feel big.

When we try to look farther into the universe we come to what appears to be the end of space but actually it's the beginning of time.

Let's invent a new tomorrow and then make it happen. Let's invent the city of tomorrow, the home of tomorrow, the transportation of tomorrow.

As children we all wonder - we wonder all the time. And that gets lost in adulthood. It gets beaten out, it gets filtered out or diluted out.

Only when you question does society move or advance at all.
