Web15 hours ago · The Hubble IR cutoff in Barrow holographic dark energy in presence of neutrino masses using the latest observational data is investigated. The aim of this paper is twofold. At first we want to show that as it is well known, for spatially flat FRW cosmologies, the holographic dark energy disfavors the Hubble parameter as a candidate for the IR … Webc) they radiate mainly in the infrared d) all of a, b, and c e) they are all so far away that the light hasnt reached us yet b) encounter a shock wave Interstellar gas clouds may collapse to form stars if they a) have very high temperatures b) encounter a shock wave c) rotate rapidly d) are located near main sequence spectral type K and M stars jelinek wut
