"Time is the fire in which we burn."
— 1937, Delmore Schwartz, Calmly We Walk Through This April's Day:
"One of the most common truisms on Earth is the advice to value or at least not waste time. Why has it become so widespread? Every person eventually realizes that time is the most valuable resource on the planet. Not oil or uranium. Not lithium or anything else, but time. Time. The very flow of time convinces us of this. Some people realize this sooner, and these are the lucky ones. Others realize it too late when they lose someone or something. People cannot avoid it, this is just a matter of time. But there is a fundamental difference that comes down to the question of time. The time of your life is under your control. The time of life of our force on the front line, the time of life of all Ukrainians who are forced to live through this terrible Russian aggression unfortunately is subject to many factors that are not all in their control. I do not wish anyone to feel like they are in my shoes, and it's impossible to give a manual on how to go through life so as not to waste time. However, one piece of advice always works. You have to know exactly why you need today and how you want your tomorrows to look like."

"So long as I travelled at a high velocity through time, this scarcely mattered; I was, so to speak, attenuated – was slipping like a vapour through the interstices of intervening substances!"

"We all have a visceral understanding of what it means for the universe to have multiple space dimensions, since we live in a world in which we constantly deal with a plurality — three. But what would it mean to have multiple times? Would one align with time as we presently experience it psychologically while the other would somehow be "different"?"

"Given the connection between increasing entropy and the arrow of time, does the Big Crunch mean that time would run backwards as soon as collapse began?"
