Next Friday is the vernal equinox, the first day of Spring, which the media often celebrates by repeating such myths as, "Day and night are equal."

In popular fiction, to qualify as another dimension means a realm must be something beyond the four dimensions of everyday reality, and thus be totally inaccessible, like public restrooms in New York. But might they really exist?

We’ll get a lunar eclipse this Tuesday morning, and it’s generating a lot of buzz, especially since such eclipses have been dramatically called Blood Moons in recent years.
