SUMMARY
The cosmic microwave background radiation (CMB) was discovered around 1965 and is detected uniformly from all directions in intergalactic space, indicating its origin outside our galaxy. This radiation exhibits a perfect blackbody spectrum, which eliminates the possibility of it being sourced from diffuse starlight. Observations confirm that the CMB exists beyond the Milky Way, reinforcing its significance in cosmological studies.
PREREQUISITES
