Alternative explanations for cosmic microwave background anomalies from "summary" of Endless Universe by Paul J. Steinhardt,Neil Turok
One intriguing puzzle in modern cosmology is the unexpected anomalies found in the cosmic microwave background radiation. These anomalies defy the conventional understanding of the universe's early evolution and challenge the prevailing inflationary model. Some researchers suggest alternative explanations to account for these inconsistencies. One alternative explanation proposes that the anomalies may be attributed to foreground contamination from our Milky Way galaxy. Dust and gas in our galaxy can emit radiation that interferes with the cosmic microwave background signal. By carefully accounting for this contamination, researchers hope to resolve the discrepancies observed in the data. Another alternative explanation involves the possibility of systemat...
