I am not a expert in this field. Maybe someone could give a better answer. But I would expect that both effects using differences. Recently there was an arcticle astro-ph/0406504 which states to measure the vacuum energy, but it was shown that only differences could be measured...

Absolutly yes. Diffeomorphism invariance is a must. Maybe the problem in QFT is caused by missing that. Not only the vacuum energy potential is infinite, in QED also the E or B field are infinite and we need renormalization. Maybe if we could define it better, everything is ok: the fields are...

I believe in in this theory and I fully agree with your answer 1. in http://math.ucr.edu/home/baez/vacuum.html" (very appreciated). Every energy contributes via T to Einsteins's eq. sure! But that's not the question. The question is: Is the "quantum field vacuum energy" a energy in the meaning...

Hi folks, There are many claims that vacuum energy has a physical relevance: in Casimir effect, in the Cosmological constant. But it seems, vacuum energy is a quantity we are not able to measure. It seems like a energy potential: the absolute value has no physical relevance, but the difference...
