I'm guilty of forgetting to look up.

I walk through a horizontal world where things are flat and long. But we live in both dimensions. Things stretch far beyond where my eyes naturally land. Buildings rise just floors above my eyeline.

There are lines that connect this human dimension with others—thin antenna bodies reminding us that this single line of sight misses the fifth and sixth stories.

We can look down too, into the earth. What's down there? How much have you really thought about it? The vertical extension—all those bones below, all that dark matter above, and here you are looking at your phone again.

Above and below.

Most of it outside our eyeline.
