Dialogue on the Tides

Talking philosophy with Galileo over coconut mojitos.

His cosmology says we aren’t the center.

We speed through space circling a star.

The tides prove it. But I am motionless.

Sun passing. Stars dancing the vernal equinox.


In 1632, Galileo published Dialogue Concerning the Two Chief World Systems which he originally originally called Dialogue on the Tides. The two systems were Ptolemy’s, who believed that the Earth was the center of the universe with the Sun, Moon, planets, and stars revolving around it, and Copernicus’ who posited that the Sun is the center of the universe.
