A wall of shadow coming: total eclipse,1979

The deepest, and most terrifying, was this: I have said that I heard screams. (I have since read that screaming, with hysteria, is a common reaction even to expected total eclipses.) People on all the hillsides, including, I think, myself, screamed when the black body of the moon detached from the sky and rolled over the sun. But something else was happening at that same instant, and it was this, I believe, that made us scream.

The second before the sun went out we saw a wall of dark shadow come speeding at us. We no sooner saw it than it was upon us, like thunder. It roared up the valley. It slammed our hill and knocked us out. It was the monstrous swift shadow cone of the moon. I have since read that this wave of shadow moves at 1,800 miles an hour. Language can give no sense of this sort of speed—1,800 miles an hour. It was 195 miles wide. No end was in sight—you saw only the edge. It rolled at you across the land at 1,800 miles an hour, hauling darkness like plague behind it. Seeing it, and knowing it was coming straight for you, was like feeling a slug of anesthetic shoot up your arm. If you think very fast, you may have time to think, “Soon it will hit my brain.” You can feel the deadness race up your arm; you can feel the appalling, inhuman speed of your own blood. We saw the wall of shadow coming, and screamed before it hit.

This was the universe about which we have read so much and never before felt: the universe as a clockwork of loose spheres flung at stupefying, unauthorized speeds. How could anything moving so fast not crash, not veer from its orbit amok like a car out of control on a turn?

Less than two minutes later, when the sun emerged, the trailing edge of the shadow cone sped away. It coursed down our hill and raced eastward over the plain, faster than the eye could believe; it swept over the plain and dropped over the planet’s rim in a twinkling. It had clobbered us, and now it roared away. We blinked in the light. It was as though an enormous, loping god in the sky had reached down and slapped the Earth’s face. – from “Toral Eclipse” (The Atlantic, August 8, 2017)
