If more vacuum energy appears with expansion and it has no limit, can infinite of this energy be created? If yes is energy infinite?
Is there any experimental evidence for vacuum energy?
Yes, there is a small amount of observational evidence for vacuum energy. The most famous example is probably the observed acceleration of the expansion of the universe, which could be due to the presence of dark energy, a form of vacuum energy. However, this evidence is still somewhat ambiguous and more research is needed in order to verify the existence and properties of vacuum energy.
