You could represent time as the distance from center to circumference, although that wouldn’t be as readily comprehensible at a glance. It’s more like the image just shows a chunk out of that sphere

Donkter@lemmy.world 6 days agoThis model does assume the big bang happened in a spheroid pattern. It’s just flattened to add time as an axis from left to right cause you couldn’t represent time otherwise.

The big bang didn’t happen in a pattern, it happened everywhere at once: nasaspacenews.com/…/is-the-universe-infinite-new-…
The universe expanding means it gets sparser. It has no edge and no center, so it’s not spherical. It’s either infinite or repeating (e.g. it might be the surface of a 4D torus, but as said: that doesn’t imply an edge). I personally believe it’s infinite and not repeating.

Yeah which is what this model is trying to represent. That the big bang occured at a central point in time, not space.
