A description of the experience
Georges Lemaitre – The Primeval atom
When the radius of space varies with time, space of variable radius is obtained. One can imagine that material points are distributed evenly in it and that spatio-temporal observations are made on these points. The angular distance of the various observers remains invariant, therefore the linear distances vary proportionally to the radius of space. All the points in space are perfectly equivalent.
If the radius increases with time, each observer sees all points which surround him receding from him and that occurs at velocities which become greater as they recede further. It is this which has been observed for the extra galactic nebulae that surround us. The constant ratio between distance and velocity has been determined.
