Aeon

philosophy religion Maturity 11-13 Next article →

An aeon is a word used to describe time. It can mean a very long period. People often use it to mean forever or eternity. The word comes from an ancient Greek word. That old word meant a century or one hundred years. Today, we use it for any time that is hard to measure. It is a big word for very big ideas.

Scientists use this word in special ways. In astronomy, an aeon is exactly one billion years. This is often written as AE. Some thinkers use it to talk about cycles of the Big Bang. Geologists also use aeons to group Earth's history. They divide our planet's past into four main parts. These are the Hadean, Archean, Proterozoic, and Phanerozoic aeons.

Many religions use the idea of an aeon. In Buddhism and Hinduism, it is called a kalpa. A mahakalpa is the life cycle of the world. Some say it lasts 1,334,240,000 years. However, these large numbers are usually symbolic. They represent a way of thinking about time.

In Gnosticism, aeons have a different meaning. They are not just periods of time. They are parts of God that come from the One. These parts are called emanations. They have many different names. Some call them Wisdom or the Anointed One. Others call them the Beginning or the Depth.

Christianity also has many ideas about aeons. Some people see them as long ages. They might talk about an age to come. This is often linked to the idea of Heaven. Some thinkers believe there was a time before the aeons. They see a difference between our present age and the next age. This helps them explain life after death.
