The discussion revolves around the concept of total energy in the context of stellar winds, shock formation, and the dynamics of expanding bubbles in astrophysical environments.
Some participants have offered thoughts on the definitions and components of total energy, while others express uncertainty about the implications of their findings, indicating a lack of consensus on whether total energy increases or decreases.
There are references to equations related to thermal and kinetic energy, and participants are grappling with contradictions in their results, suggesting potential gaps in information or understanding.

If a big star gives of wind , forming shock and then a bubble .. And then this bubble is driven by pressure
Also as the bubble expands the surrounding mass gets added to it
Does it make sense for the Total energy to increase ?
