I’m in a short story club where today’s discussion story is “Common Time” by James Blish from 1953. This blog will be my comment to the group, but I feel my insight is personal enough for this blog.
“Common Time” is about an astronaut in an experimental spaceship traveling at twenty-two times the speed of light. When the astronaut regains consciousness after launch he can’t move and it takes forever to open his eyes. He discovers that time is moving very slowly. He is able to count to 7,200 between each tick of the second hand on his clock. Eventually, his perspective speeds up until the hour hand is flashing around. The story is about how this astronaut reacts to the different perspectives of time.
I think time is a fascinating topic. I use the picture of a hummingbird above to illustrate subjective time. To a hummingbird, a human appears like a statue, frozen in time. I’ve often wondered how an intelligent robot will perceive time. The clock speed of computer chips is currently in the gigahertz range – that’s billions of cycles per second. Will AI minds even notice us? Of course, their bodies won’t be able to move a billion times faster than ours.
I also like to think about the concept of now. Is there a universal now everywhere? Now exists without clocks. Now can exist without even the concept of time. If we had a smartphone connection to a planet 1,000 light-years away that had an instant speed of communication we could talk to our alien friends in the now. Is that true for the whole universe? Or do different locations experience different nows? What about the multiverse? Is there one moment of now everywhere? Or many?
How long is the moment of now to a hummingbird or future robot?
Yesterday I woke up feeling better than I have in years. I noticed this when I was planning my day. I felt good enough to plan to work on a long-term project. Lately, I haven’t been feeling good, and the only things I wanted to do were those activities that focus on the moment. I was disappointed yesterday when less than two hours later after my aches and pains returned I only felt like reading, watching TV, or listening to music. I loved that feeling I had more time.
I can remember being young and feeling like I had all the time in the world to do everything I ever wanted to do. I’m writing this essay early in the morning because I feel like I have enough time to finish it. I won’t feel like that in a little while.
