Expansion of the Universe Violates Conservation of Energy?

AI Thread Summary
The discussion centers on whether the acceleration of the universe's expansion, driven by vacuum energy from newly-formed space, violates the conservation of energy. Participants question if this energy represents a net surplus not derived from existing energy forms, potentially challenging the conservation principle at a cosmological level. It is noted that the conservation of energy may not apply in cosmology due to difficulties in defining energy on such scales. The concept of vacuum energy and its equilibrium state is also explored, raising questions about the origins of newly formed space. Overall, the conversation highlights ongoing uncertainties in understanding energy conservation in the context of cosmic expansion.

If the acceleration of the expansion of the universe is driven by the vacuum energy 'created' by newly-formed space, what is the counterpart of this energy? Is it a net surplus energy injected into the universe and not converted from another pre-existing form of energy? In that case, is the conservation of energy actually violated at the cosmological level?

I don't believe there really is a solid solution for this problem yet... Or is there?

The conservation of energy as a law is not applicable in a cosmological sense. There are a number of very good FAQs on this site so I will not elaborate too much.
 
The vacuum in space is in equilibrium. The "power" of a vacuum can only be found within an atmosphere, where it simply replaces that which was used to create it.
 
where is this newly formed space coming from, the extra dimensions?
