Making space for IT

Abstract

Interestingly, making space that you really wait for now is coming. It's significant to wait for the representative and beneficial books to read. Every book that is provided in better way and utterance will be expected by many peoples. Even you are a good reader or not, feeling to read this book will always appear when you find it. But, when you feel hard to find it as yours, what to do? Borrow to your friends and don't know when to give back it to her or him.

Constraints on running vacuum models with the baryon-to-photon ratio

“…The conservation of photon number is also based on the requirement that CMB radiation could be regarded as black-body radiation, which therefore results in non-conservation of the internal energy of photons. In the ΛCDM model, we can not explain the energy loss of photons due to the expansion of space-time [72][73][74] but baryons have no such problem. In this section, we analyse whether the problem can be solved in RVMs.…”

“…If photons in RVMs are coupled to vacuum, the redshift of a single photon in the expanding universe will be modified comparing with its "free expansion" in the ΛCDM model. We wonder whether such expansion of photons in RVMs could solve the problem of energy non-conservation in the ΛCDM model 2 [72][73][74]. Furthermore, the impact of running vacuum on CMB may lead to new estimations on the size and age of the observable universe at certain epochs.…”
