The Astroverse (alternatively Ikaverse) is a verse containing Meskoverses and it looks like the shape of an infinity. It's shape isn't actually an infinity but it is covered by blue gas around it and making an infinity. If it weren't for the blue gas, it will look like green because of the Meskoverses and doesn't look like an infinity because of the Meskoverses being placed randomly with some hollows.
Other Astroverses are very, very, very far from each other making us see the Astroverse in a void like we're lonely. An astrofinity is a number that is an astronomical ordinal like this verse's size which is "Omni Endless Eternity Infinity Transfinity Astrofinity".
