The Cosmic Microwave Background CMB is a powerful evidence for the Big Bang theory and is accepted as such by the vast majority of the scientific community. There are always those who doubt the CMB and its interpretation. I am one of those!A sneak peek: "The CMB started 380,000 years after the big bang, when the universe became transparent. The entire universe was filled with mainly neutral hydrogen, and flashes of light (photons) were shooting everywhere and in various directions through the cosmos. The cosmos continued to expand, but no new flashes of light were generated, which means that the photons did not expand with the cosmos either. The hydrogen-filled cosmos expanded, but the photons did not expand with it. They continued to follow their flash directions undisturbed. 300 million years after the big bang, we are interested in some of the CMB radiation near the galaxy JADES-GS-z14-0. We want to see how the two types of radiation behave. The redshift of the CMB 300 million years after the big bang is about 75 according to the scientific literature. From that moment on, the CMB and the light from JADES-GS-z14-0 travel towards us together. I cannot accept that the CMB arrives at z = 1,100 (from about 75 to 1,100) while JADES has a redshift of only 14.32 (from 0 to 14.32). To explain the large redshift of the CMB, a fourth redshift was introduced: the cosmological redshift (as space expands, the wavelength of the radiation increases proportionally). When the CMB undergoes this cosmological redshift, so should the light from JADES. But it doesn't! Therefore I would dare to conclude: the CMB redshift cannot be 1,100."In this paper I try to prove that there is no CMB. What then are the radiations measured by Penzias and Wilson in 1964 and subsequently measured with increasing accuracy by the COBE, WMAP and Planck satellites. The measured spectrum of the radiations is a property of the dark, or rather, cosmic energy. The radiation of this cosmic energy caused the unexpected noise in the radio receivers of Penzias and Wilson. The cosmic energy is full of quantum energy and particles and antiparticles that appear for a very short time and then disappear again. They give off strange signals, and these signals are called quantum fluctuations. The strange signals that are emitted here, the quantum fluctuations, can be picked up as electromagnetic background noise. And these are the signals that the researchers call the cosmic background radiation. I would rather call that radiation the Cosmic Foreground Radiation. Cosmic Microwave Foreground (CMF) instead of Cosmic Microwave Background (CMB).
