Does anybody know why the cosmic web is shaped like a web? I feel like it would be more likely that it is more like a galaxy with a supermassive black hole in the center, if that were true, what would happen?

1$\begingroup$ It's just a random distribution of the galaxies. It just looks like a web but you can see that it is not exactly webshaped as it is random. It might have been named Cosmic Web although it is not a web at all. $\endgroup$– ProscionexiumCommented Mar 4 at 15:32

It looks like a neutral net:
It should be random on the largest scale, but there is clearly structure from dynamic interactions on large scales.
You really can't say what it would look if it looked like a giant galaxy other than, wait for it, a giant galaxy.
You'd have to get quantitive, include dark matter (ofc), and work out mass distributions for proper galactic rotation curves. It might not scale when the would-be galaxy size/time-scales require the Hubble constant be included into the dynamics.
