this animated torus like structure model of cosmos explains a steady state universe with the infinite cycle of expansions and contractions of space ( big bangs and crunches)
imagine that we are in its surface somewhere below the equator. it is not seen in the animation but the bottom singularity of the torus is what scientist posit as a white hole. this is also a singularity like a black hole only opposite that instead that it sucks everything, it spews everything out. this therefore is can be the big bang part of the whole dynamic cycle. so if we are below the equator, we are near this white hole and when we measure the surface of our sphere we will perceives that everything is expanding. ( the animation does not show this but the surface of the image was divided in hexagon to see that it contracts when near the pole of the torus) using our imagination, we will see at the bottom that a hexagon shape of space will slowly form and expand until it reach the equator then slowly it will contract to a singularity as it reaches the pole.
