A logarithmic timeline is a type of timeline where events are spaced out according to the size of the event or the amount of time that has passed since it happened. This means that events that happened a long time ago are spaced out much more than recent events. For example, if an event happened 1000 years ago, it might be very far away from an event that happened just 100 years ago. This timeline helps you to see events that happened in the past more easily.
