The article presents findings from the BOOMERanG experiment, which used a balloon-borne microwave telescope to map the cosmic microwave background (CMB) radiation. The experiment produced high-resolution maps of the CMB, revealing a peak in the angular power spectrum at multipole $\ell_{peak} = (197 \pm 6)$. This peak is consistent with predictions from cold dark matter models in a flat (euclidean) Universe, as favored by standard inflationary scenarios. The results support the idea that the universe is flat, with a total energy density close to the critical density. The CMB anisotropies observed provide insights into the early universe's structure and evolution. The experiment's high-resolution maps, combined with detailed analysis of the angular power spectrum, confirm the presence of a peak at $\ell \approx 200$, which is a key indicator of a flat universe. The findings are consistent with a subset of cold dark matter models and contradict current models based on topological defects. The data also show that the universe's geometry is Euclidean, with a total density $\Omega_0$ within the range $0.88 < \Omega_0 < 1.12$ at 95% confidence. The BOOMERanG experiment's results provide strong evidence for a flat universe and highlight the importance of CMB anisotropies in understanding the universe's structure and evolution. The study also addresses potential foreground emissions and their impact on the CMB measurements, demonstrating the experiment's ability to distinguish between CMB anisotropies and other sources of radiation. The results contribute significantly to our understanding of the universe's fundamental properties and the role of dark matter in its evolution.The article presents findings from the BOOMERanG experiment, which used a balloon-borne microwave telescope to map the cosmic microwave background (CMB) radiation.
