Every single one of us has benefited from the work that Stephen Hawking did over the course of his lifetime. His most major discovery was about black holes, and that lead to what we really know about our solar system today. Today we remember him by some of his most famous quotes, as put together by CNN.
"It would not be much of a universe if it wasn't home to the people you love."
"I wouldn't compare it to sex, but it lasts longer." -- at a science festival in 2011.
However difficult life may seem, there is always something you can do and succeed at. It matters that you don't just give up." -- at an Oxford University Union speech in 2016.
"So remember, look at the stars and not at your feet." -- at the Sydney Opera House in 2015.
"I would never claim this. People who boast about their IQ are losers."-- in response to a 2017 question if he believed he was the most intelligent person in the world
"May you keep flying like superman in microgravity." -- to NASA astronauts in 2014.
"God may exist, but science can explain the universe without the need for a creator." -- in a 2010 CNN interview.
"The scientific account is complete. Theology is unnecessary." -- in a 2010 CNN interview.
"I have always tried to overcome the limitations of my condition and lead as full a life as possible. I have traveled the world, from the Antarctic to zero gravity. Perhaps one day I will go into space." -- to the New York Times in 2011.
"I have already completed a zero gravity flight which allowed me to float weightless, but my ultimate ambition is to fly into space." -- to ITV in 2017.
"My [physician assistant] reminds me that although I have a PhD in physics, women should remain a mystery." -- in his first Reddit AMA. (His PA is a woman, by the way.)
We remember him today as his family and loved ones prepare to lay him down for his final nap. Thank you Stephen Hawking
