Is vacuum energy infinite? If it is, how and why? Is it dark energy?
Are there any experiments that prove the existence of vacuum energy or dark energy?
While there is no direct experimental evidence of vacuum energy or dark energy, their existence is supported by the behavior of the universe at large scales. Theories of vacuum energy and dark energy are used to explain phenomena such as the accelerating expansion of the universe and the behavior of light passing through space.
