Sean Carroll on time-travel
Sean Carroll on time-travel
(Saw it first here. Then here and among other hip UK designers that I don’t know personally but wish I did.)
Giving myself five minutes for this:
1. I’m learning that there is a limit to the amount of information I can take in and synthesize properly. Rather than just cutting some out, I want to give serious thought to what I take in. Particularly in regard to reading web content, the echo chamber is a significant factor. I want to impose a rule, something like “don’t read pseudo-writers.” Now about that definition of “pseudo”… oh, and “writers.”
2. Trust and knowledge. In many ways, human knowledge is a house of cards. Trying to dismantle it carefully, getting to the root, fundamental, non-negotiable concepts without which everything else you know cannot be is an exercise not to be undertaken at bedtime. During walks to work is probably better…
3. Workspace. Finding a balance between efficiency/productivity/inspiration.
4. Design simplicity for tomorrow… My last two articles have dealt with this - what the underlying purposes should be for web design and marketing and how we should strive for increased simplicity. My next one will be out this week and hone in on the idea of respecting attention.
5. Time travel. Because I often am, and because of this.
What are you thinking about right now?
Wonderful. Via The Long Now Foundation:
It’s a reverse time lapse put together by Greg Mercer and Emily Ward (editing), and David Quednau (animation). Unwinding 20,000 years of a modern American city and frontier outposts, Native American settlements and the last ice age, we arrive in their world and resurrect them in film.
Wow. Nimoy with a mustache! But this is fun…
This design by Project Project for this year’s Whitney Biennial catalog combines several things I like: the Whitney Biennial, time-travel, and infinity. This spread also features the year of my birth…

J. Richard Gott on to when, given the opportunity, he would travel in time. When asked why, he replied:
Because that’s how long homo sapiens have been around. I’ve done some thinking about time not just in terms of travel or physics, but in relation to how long things last—things like the Berlin Wall or Broadway plays or the human species. In 1993, I published a paper inNature that applied one of the most famous postulates in science, the Copernican principle, to time.
The Copernican principle is simply the idea that your location in the universe is not special. Most likely your last name falls somewhere in the middle ninety-five percent of the phone book, not right at the beginning or the end, which would be special. And most likely you’re living sometime in the middle ninety-five percent of the length of the human species. Otherwise you’d be in a special position and that’s just less likely.
Using some simple math, I predicted with ninety-five percent confidence that the human race would last at least another 5,100 years, but less than 7.8 million years. Now, that’s a wide range, but an important one. The fate of our own species is supremely important to us. Some people predict we’ll die out in the next hundred years if we aren’t careful; others think we’ll just last indefinitely. Neither is likely. In any case, we’d better not be complacent. The Earth is littered with the bones of extinct species…
My estimates of the future longevity of the human species are based entirely on our past longevity as an intelligent species—the only one we know—and make no assumptions that our fate will be similar to that for other species. However, my estimates give us a total longevity (past plus future) quite comparable to that observed for other mammal species, whose average longevity is 2 million years.
Why the coincidence? Well, if we remain confined to Earth, we are subject to the things that routinely cause other mammal species to go extinct. That’s why I am so concerned about the space program. So far, the space program is very brief, and the Copernican principle predicts it will probably go out of business sooner rather than later. And clearly we would increase our chances of surviving if we colonize space.
