If dark energy is created with expansion can infinite of it be created?

The concept of dark energy and its behavior in an expanding universe is complex and still largely theoretical. Here are some key points to address your question:

Density of Dark Energy

In the most common models of dark energy, such as the cosmological constant (λ-CDM model), the density of dark energy is considered to remain constant even as the universe expands. This means that as new space volume is created, it contains the same amount of dark energy per unit volume as the previously existing space24.

Infinite Expansion and Dark Energy

If the universe continues to expand indefinitely, the total amount of dark energy would indeed increase because the volume of space is increasing. However, this does not imply the creation of new dark energy in the sense of violating the principle of conservation of energy. Instead, the existing dark energy density fills the newly created space, maintaining a constant density per unit volume24.

Theoretical Implications

The idea that dark energy fills new space as it is created does not violate energy conservation because it is a property of the vacuum itself, rather than a form of energy that is being generated or destroyed. This is consistent with the notion that dark energy is a fundamental property of space that scales with its volume24.

In summary, while the total amount of dark energy in the universe would increase with infinite expansion, this is not seen as a violation of energy conservation but rather as a consequence of dark energy's constant density filling the expanding space.
