WebL'effondrement du gaz pour former des étoiles sur n'importe quelle échelle de temps utile a été inhibé par la transparence du gaz (au sens d'émission, pas d'absorption de photons). La transparence a empêché la perte de chaleur par rayonnement, ce qui a empêché la compression du gaz par gravité.

WebBefore the cosmic microwave background (CMB) was released, photons and ordinary particles were tightly coupled together, forming a single ‘fluid’ of matter and radiation. As … WebSep 3, 2024 · The CMB photons that we see come from a last-scattering surface that is only about 20 Mpc thick. In other words, we only see a 20 Mpc cross-sectional slab of the 150 Mpc radius shell. Nevertheless, the fact that the photon perturbations are carried out into 150 Mpc radius shells is the cause of the characteristic 1 degree spot size in the ...

Gray’s work is on display in … WebThe discovery of the cosmic microwave background (CMB) in the early 1960's was powerful confirmation of the Big Bang theory. Since the time of recombination, cosmic background photons have been free to travel uninhibited by interactions with matter. Thus, we expect their distribution of energy to be a perfect blackbody curve. A blackbody is the ...

WebWhen light particles, or photons, from the CMB scatter off electrons in the gas between galaxies, they get bumped to higher energies. In addition, if those galaxies are in motion with respect to the expanding universe, the CMB photons get a second energy shift, either up or down, depending on the relative motion of the cluster. ...
