I can't understand how an observer in either a spherical, hyperbolic or flat universe will be able to tell the difference between the three. Surely if he was to measure the angles in a triangle in all three cases, the light would bend in accordance to the curvature of the universe and show that in each case, the angles in a triangle = 180.
I can understand how this works from an outside perspective of the universe, but not how insiders like this would be able to tell the difference
help!?
