Ubiquity is the state of being everywhere all the time. Some ubiquity is real (the ubiquity of sadness at a funeral), and some only seems real (the ubiquity of cowboy boots in Texas).
A god is a great example of ubiquity: an all-knowing deity that exists in every nook and cranny. The Latin root word ubique means “everywhere,” and something with ubiquity is indeed everywhere, and hard to avoid. Sometimes ubiquity is a mind trick, like noticing that 1134 looks like “hell” upside down, then you notice that the clock reads 11:34, your groceries cost $11.34, and you have 1134 emails in your inbox. Wherever you go, the ubiquity of 1134 finds you.
