“Work gives you meaning and purpose and life is empty without it.” -Stephen Hawking Throw a book into a black hole, and the information must somehow wind up inside. Same goes for a star, a planet, or even a single proton: that information must be maintained. But allow enough time to pass, and quantum theory…

“It was a strange lightness, a drifting feeling. Zero gravity. I understood that everything that once seemed solid and immovable might just float away.” -Lisa Unger If you want to experience zero gravity, all you need to do is go to space, turn your rocket off and feel that weightless sensation, right? Except, from up…

“You may hate gravity, but gravity doesn’t care.” –Clayton Christensen If all we had were galactic rotation curves — like those measured by Vera Rubin — we would know that something was wrong with our picture of the Universe, but we wouldn’t know how. Two equally good explanations, that there was either a flaw in…

“The joy of life consists in the exercise of one’s energies, continual growth, constant change, the enjoyment of every new experience. To stop means simply to die. The eternal mistake of mankind is to set up an attainable ideal.” -Aleister Crowley As we learn more and more about the Universe, we’d like to describe it…

“It’s the first time the universe has spoken to us through gravitational waves, up to now we’ve been deaf to them.” -Dave Reitze No doubt about it: the greatest science advance of 2016 was the end of the century-long wait for the first direct detection of gravitational waves. Not only were we able to detect…

“Because philosophy arises from awe, a philosopher is bound in his way to be a lover of myths and poetic fables. Poets and philosophers are alike in being big with wonder.” -Thomas Aquinas Sure, you’ve studied a little physics. You know about Einstein and General Relativity, the quantum nature of the Universe and the fundamental…

“First, you should check out my house. It’s, like, kinda lame, but way less lame than, like, your house.” -Lumpy Space Princess, Adventure Time Billions of years ago, before the Universe contained clusters, galaxies, stars or even neutral atoms, everything was uniform. Almost perfectly uniform, where the densest regions weren’t even 0.01% denser than average.…

“The bedrock nature of space and time and the unification of cosmos and quantum are surely among science’s great ‘open frontiers.’ These are parts of the intellectual map where we’re still groping for the truth – where, in the fashion of ancient cartographers, we must still inscribe ‘here be dragons.’” -Martin Rees In 2015, LIGO…

“I just think too many nice things have happened in string theory for it to be all wrong. Humans do not understand it very well, but I just don’t believe there is a big cosmic conspiracy that created this incredible thing that has nothing to do with the real world.” -Edward Witten You don’t have…

“The whole edifice of modern physics is built up on the fundamental hypothesis of the atomic or molecular constitution of matter.” -C. V. Raman As far as humans have figured out, there are four fundamental forces in the Universe: the three of the Standard Model (electromagnetism, the weak and strong nuclear forces) and General Relativity,…
