I thought I had to make the case for this in Casimir cavities and microwave waveguides but I found the paragraph below in an October 22nd blog "Vacuum or zero point <http://www.theimagineershome.com/blog/?p=2297> energy and quantum fluctuations" that seems to indicate this is already known and understood. Can I take it that time dilation in a Casimir cavity was already a known fact or am I reading too much into this blog?
[Snip] From The Imagineer's Chronicles <http://www.theimagineershome.com/blog/> according to Einstein's space-time concepts time is dilated or always "moves" slower in volumes that contain a different energy content than the ones from which they are observed. This means the time dilation associated with quantum fluctuations will be cumulative even though the energy associated with the particle antiparticle pairs is not. [end snip]
