So it is 4 dimensional. 3) Space and time graph – used to show events, and how earth moves through the expanding universe. 4) Slants – Determine the speed applied to observations. 5) Events – Any point on the space and time graph. 6) Space on graph – The vertical line on the space and time graph. 7) Time on graph – The horizontal line on the space and time graph. 8) Positive curvature – All angles add up to be more than 180 degrees. 9) Negative curvature – All angles add up to be less than 180 degrees. 10) Flat curvature – All angles add up to be equal to 180 degrees.
