This entity, named Hooleilana draws inspiration from the Kumulipo, a Hawaiian chant that speaks of creation & the genesis of structures.

Known as Baryon Acoustic Oscillations (BAO), these ripples are remnants of the universe’s birth.

The discovery of the bubble was facilitated by data from Cosmicflows-4, the most extensive compilation of galaxy distances to date.

According to Daniel Pomarede of CEA Paris-Saclay University in France, I am the cartographer of the group, & mapping Hooleilana in 3 dimensions helps us understand its content & relationship with its surroundings.

The Laniākea Supercluster was identified by the same team in 2014, which, in comparison, is dwarfed by Hoʻoleilana.

Simulations have shown that the shell structure identified as Hoʻoleilana has less than a 1% chance of being a mere statistical anomaly.

The size of Hoʻoleilana aligns with observations of the universe’s local expansion rate & galaxy flow on large scales.
