"The chloroplast is a three billion year-old solar energy collector. This sub-microscopic solar battery is what drives all the forests, and the fields, and the plankton of the seas, and the animals, including us."

"[Currently] our Sun is poised in a stable equilibrium between gravity and nuclear fire. . . . [F]our or five billion years from now . . . it will become bloated [and] will envelop and devour the planets Mercury and Venus and possibly the Earth. [Finally it will shrink] a hundredfold to the size of the Earth [and will be] a white dwarf star."

"Some stars are so far away, it takes eons for their light to get to Earth. By the time the light from some stars gets here, they are already dead. For those stars, we see only their ghosts."

"Black holes may very well be tunnels through the universe. [If you could somehow survive the ride on] this intergalactic subway system, you could travel to the farthest reaches of spacetime, or you might arrive in someplace even more amazing. We might find ourselves in an altogether different universe."

"Thales kindled a flame that still burns to this day: the very idea of cosmos out of chaos, a universe governed by the order of natural laws that we can actually figure out. This is the epic adventure that began in the mind of Thales."
