The H0 tension: did a QCD meV axion emerge?
Massimo Cerdonio
I discuss the possibility that the difference in the measured Hubble constant Ho between the current, Late, and the z ~1100, Early, epochs is due to the emergence in between of a n…
About the measure of the bare cosmological constant
Massimo Cerdonio
I try to revive, and possibly reconcile, a debate started a few years ago, about the relative roles of a bare cosmological constant and of a vacuum energy, by taking the attitude t…
Comment to "How does Casimir energy fall? IV. Gravitational interaction of regularized quantum vacuum energy" by K A Milton et al., Phys Rev D 89 064027 (2014)
Massimo Cerdonio, Carlo Rovelli
The Paper actually concerns a toy model, not physical Casimir cavities made of conducting plates, but the results are taken implicitly to apply in general. We question on general p…
A Casimir cannot cavity fly
Massimo Cerdonio, Carlo Rovelli
The field inside a Casimir cavity has an effective negative mass, which acts as a buoyancy force in a gravitational field. Can this render the total mass of the cavity negative, ma…
Measuring Gravito-magnetic Effects by Multi Ring-Laser Gyroscope
F. Bosi, G. Cella, A. Di Virgilio +19
We propose an under-ground experiment to detect the general relativistic effects due to the curvature of space-time around the Earth (de Sitter effect) and to rotation of the plane…
A laser gyroscope system to detect the Gravito-Magnetic effect on Earth
A. Di Virgilio, K. U. Schreiber, A. Gebauer +5
Large scale square ring laser gyros with a length of four meters on each side are approaching a sensitivity of 1x10^-11 rad/s/sqrt(Hz). This is about the regime required to measure…
