The Hyperverse has 10th Layer of Transfinite Xenoverses, but most of the Xenoverses are bigger than our own. Its weird diameter is like this: 5 x 10^2,489,000,000,000,000,000 or 5 x 10^(2.5 x 10^18) light years. Also, it has the Illuminati in it, who is the leader of all Archverses within his virtual reality. He created this simulation after his Archverse was deleted, and while doing so, he decided to give himself more virtual Archverses to give himself "more power". Because these simulations are imperfect projections, naturally, if you would go through the virtual Archverses within a Hyperverse and through another Hyperverse within the Archverses 1 million times, then you will eventually end up at the Undefinedverse.
Some Hyperverses are bigger than their own. Only because of how many different Virtual Realities they contain because of their Xenoverses and Metaverses. In fact, If we're talking about Simulations again, There could be Metaverses bigger than Xenoverses. Which is actually complicated. If only they weren't good at balancing themsleves. That's why the Beyond Abstract entities aren't worried about collisions.
