黑洞不仅仅是宇宙的真空吸尘器；它们是测试我们物理理论极限的终极实验室。

The most powerful weapon you have is your voice.

Science is a marathon, not a sprint.

The past is a foreign country; they do things differently there.

I'm not a feminist. I hail men, I love men. I celebrate American male culture, and beer, and bars and muscle cars... But what I really believe in is women.

I don't care if you're black, white, straight, bisexual, gay, lesbian, short, tall, fat, skinny, rich or poor. If you're nice to me, I'll be nice to you. Simple as that.
