Illustration of the evolution of volume and energy based on the segmented superbubble morphology. The volume undergoes a rapid surge within the first 5 Myr, followed by periodic increases after supernova-like energy injections (red crosses), and decreases as matter flows into adjacent structures or escapes into the halo through formed tunnels. The energy remains consistently around 10⁴⁴ J throughout the bubble’s lifetime, indicating its ability to retain energy while maintaining a discrete structure.
