It wasn’t the size of a potato. It was everywhere all at once. There is no three dimensional shape of the universe, no boundary, and edge. Still, between galaxies space is expanding. That means everything below a certain amount of mass density is getting further from every other mass density. Within the mass density space does not expand. We are not getting further away from other stars. But saying the universe was the size of the potato dramatically misses what we believed the universe is today and what the article says. It abstracts the nature of things to what is familiar to you, but misses the actual nature of things.
Note the Big Bang is a point in time where all paths started, as stated in the article. It’s a mathematical singularity. It’s not an explosion as you think of it. It was a sudden expansion of all points in space creating vastly more space between the points. But since space has no boundary it didn’t get bigger, and it wasn’t smaller.

- fnordpiglet 4y agoI think PBS space time does a good job explaining these things, but you’re right it doesn’t map to our understanding of how mass and space work in a Newtonian world. These videos give some explanation and link through internally to more details. https://youtu.be/bUHZ2k9DYHY https://youtu.be/bUHZ2k9DYHY https://youtu.be/bUHZ2k9DYHY https://youtu.be/bUHZ2k9DYHY
