The Order of Time
“The entire evolution of science would suggest that the best grammar for thinking about the world is that of change, not of permanence. Not of being, but becoming. He says, “The difference between things and events is that things persist in time; events have limited duration.” He gives a rock as an example of a thing, as contrasted with an event. But, he says, “On closer inspection, in fact, even the things that are most ‘thinglike’ are nothing more than long events.” A rock isn’t a rock forever — even though it might seem like that to us humans. It starts off as a bunch of sand, gets compressed and melted, exists as a rock for a while, and eventually wears away into sand again. Even to say it started off as sand is wrong, because the sand wasn’t always sand either. The molecules that make up each grain of sand have their own complicated history. Therefore, any given rock’s existence as a rock is an event within the long, long history of its constituent, parts.”

Emptiness
“Pike was good at waiting, which was why he excelled in the Marines and other things. He could wait for days without moving and without being bored because he did not believe in time. Time was what filled your moments, so if your moments were empty, time had no meaning. Emptiness did not flow or pass; it simply was. Letting himself be empty was like
putting himself in neutral: Pike was.”

Time: Do past, present and future exist all at once?
Near the end of the video there’s a reference to presentism and eternalism.
“Philosophical presentism is the view that neither the future nor the past exists. In some versions of presentism, the view is extended to timeless objects or ideas (such as numbers). According to presentism, events and entities that are wholly past or wholly future do not exist at all. Presentism contrasts with eternalism and the growing block theory of time, which hold that past events, like the Battle of Manzikert, and past entities, like Alexander the Great’s warhorse Bucephalus, really exist although not in the present. Eternalism extends to future events as well.” (Wikipedia)
Most of my reading (and many hours of meditation) makes me lean toward presentism. It’s always now. But –as suggested in the video– physicists insist the math argues for eternalism. And I’d kind of like for that to be “true” as well. Perhaps both can be true, depending on what time it is.
Giving up on time
“He was used to the disappearance of large parts of his life. Sometimes, he passed out at ten o’clock in the morning, and when he woke up, it was nine o’clock in the morning — some other morning. At first, the time changes were disorienting, but over the course of a couple of years, he got used to it. He simply gave up on time — now life was daytime and nighttime, strung along like beads on a string, and the minute, hour, and date were irrelevant.”

What is time to the brain?
David Eagleman at the FQXi SETTING TIME ARIGHT conference (2011), an interdisciplinary meeting investigating the nature of time.
My favorite line from his talk: “We are moving creatures that run on batteries.”
How to slow down time
There’s a character in the novel Catch-22 that spends his days playing horseshoes. He hates pitching horseshoes but doing it slows down time and makes his life longer. At least that’s the way I remember it. David Cain recommends mediation. “Lengthening our years by deepening our days.” And he calls “bunk” on the notion that time moves faster as we get older because we have less time remaining:
“You’re not accelerating towards your grave. It’s just a series of compounding illusions that tend to happen when we habitually ruminate about time. And there are things we can do to see through those illusions.”
I have little doubt that time — as we experience it — is an illusion. But it is a powerful one. Mr. Cain offers valuable insights in how to manage this imaginary resource.
The Rise of Exotropy
The following passage is from Kevin Kelly’s What Technology Wants.
Most hydrogen atoms were born at the beginning of time. They are as old as time itself. They were created in the fires of the big bang and dispersed into the universe as a uniform warm mist. Thereafter, each atom has been on a lonely journey. When a hydrogen atom drifts in the unconsciousness of deep space, hundreds of kilometers from another atom, it is hardly much more active than the vacuum surrounding it. Time is meaningless without change, and in the vast reaches of space that fill 99.99 percent of the universe, there is little change.
After billions of years, a hydrogen atom might be swept up by the currents of gravity radiating from a congealing galaxy. With the dimmest hint of time and change it slowly drifts in a steady direction toward other stuff. Another billion years later it bumps into the first bit of matter it has ever encountered, After millions of years it meets the second. In time it meets another of its kind, a hydrogen atom. They drift together in mild attraction until aeons later they meet an oxygen atom. Suddenly something weird happens. In a flash of heat they clump together as one later molecule. Maybe they get sucked into the atmosphere circulation of a planet. Under this marriage, they are caught in great cycles of change. Rapidly the molecule is carried up and then rained down into a crowded pool of other jostling atoms. In the company of uncountable numbers of other water molecules it travels this circuit around and around for millions of years, from crammed pools to expansive clouds and back. One day, in a stroke of luck, the water molecule is captured by a chain of unusually active carbons in one pool. Its path is once again accelerated. It spins around in a simple loop, assisting the travel of carbon chains. It enjoys speed, movement, and change such as would not be possible in the comatose recesses of space. The carbon chain is stolen by another chain and reassembled many times until the hydrogen finds itself in a cell constantly rearranging its relations and bonds with other molecules. Now it hardly ever stops changing, never stops interacting.
Is time real?
A pretty good (admittedly brief) look at two views of time:
- Presentism: there’s nothing but the eternal now. Here, the past and the future are only present in our minds.
- Eternalism: The past, present, and future aren’t the makings of our conscious mind. They’re as real as the dimensions of space. ‘Now’ is to time, as ‘here’ is to space.
Alas, they both make sense to me.
