Four Dimensions:What?! Just when you think you've got it all figured out, scientists start adding more dimensions. Most physicists, including Einstein, describe the fourth dimension as time. This fourth dimension is essential when studying an event. For example, imagine you are going to a party at the corner of 7th Avenue and 2nd Street on the 4th floor. You could abbreviate that location with the coordinates 7, 2, 4, representing the three dimensions of space. But in order to describe an event, you need to add a time and/or fourth coordinate. If the party is at 3 pm, your coordinates for the event would be 7, 2, 4, 3.So time is an essential dimension for discussing events.
