Quote by Brian Greene

"The universe is a pretty big place. If it's just us, seems like an awful lot of wasted space."

"String theory envisions a universe in which there are more dimensions than the four we observe."

"Physics is really nothing more than a search for ultimate simplicity, but so far all we've found is ultimate complexity."

"The universe doesn't owe us comprehensibility."

"Time waits for no one."

"Time spent with loved ones is never wasted."

"I've been alive for a long time. Long enough to know that you can't trust anyone."

"The past always catches up with you."
