“A watch worn by a particle of light would not tick at all. Light realizes the dreams of Ponce de Leon and the cosmetics industry: it doesn't age.”

“Gravity is matter’s sugar daddy.”

“...things are the way they are in our universe because if they weren't, we wouldn't be here to notice.”

“comparing infinities is a treacherous business”

“Physicists have come to realize that mathematics, when used with sufficient care, is a proven pathway to truth.”

“We all love a good story. We all love a tantalizing mystery. We all love the underdog pressing onward against seemingly insurmountable odds. We all, in one form or another, are trying to make sense of the world around us. And all of these elements lie at the core of modern physics. The story is among the grandest -- the unfolding of the entire universe; the mystery is among the toughest -- finding out how the cosmos came to be; the odds are among the most daunting -- bipeds, newly arrived by cosmic time scales trying to reveal the secrets of the ages; and the quest is among the deepest -- the search for fundamental laws to explain all we see and beyond, from the tiniest particles to the most distant galaxies.”

“En un universo infinito hay infinitas copias. En algunas, su doble está leyendo ahora esta frase, a la par que usted. En otras, se la ha saltado, o siente que necesita tomar algo y ha dejado el libro. Y en otras ..., bien, no tiene un carácter muy agradable y es alguien al que usted no gustaría encontrar en un callejón oscuro”

“You should never be surprised by or feel the need to explain why any physical system is in a high entropy state.”

“All you are is a bag of particles acting out the laws of physics. That to me is pretty clear.”

“But, as Einstein once said, “For we convinced physicists, the distinction between past, present, and future is only an illusion, however persistent.”5”

“When kids look up to great scientists the way they do to great musicians and actors, civilization will jump to the next level”

“The boldness of asking deep questions may require unforeseen flexibility if we are to accept the answers.”

“For string theory to make sense, the universe should have nine spacial dimensions and one time dimension, for a total of ten dimensions.”

“...quantum mechanics—the physics of our world—requires that you hold such pedestrian complaints in abeyance.”

“Cosmology is among the oldest subjects to captivate our species. And it’s no wonder. We’re storytellers, and what could be more grand than the story of creation?”

“Understanding requires insight. Insight must be anchored.”

“Assessing existence while failing to embrace the insights of modern physics would be like wrestling in the dark with an unknown opponent.”

“Science is the process that takes us from confusion to understanding...”
