The CMB is the oldest light in the universe, a remnant of the Big Bang, and a uniform glow of microwaves that fills the entire universe.

The CMB provides evidence for the Big Bang theory, helps determine the age and size of the universe, and allows us to study the early universe.

The temperature of the CMB is 2.725 Kelvin, which is very close to absolute zero.

The polarization of the CMB is caused by the gravitational waves, the scattering of light, and the magnetic fields.

The polarization of the CMB provides evidence for the inflationary universe, helps determine the geometry of the universe, and allows us to study the early universe.

None of the above Indian astronomers made significant contributions to the study of the CMB, as the concept of CMB was not known in ancient India.

The CMB is not used in Indian astronomy, as the concept of CMB was not known in ancient India.

India is planning to launch a satellite dedicated to CMB research, Indian astronomers are collaborating with international teams to study the CMB, and India is hosting international conferences on CMB research.

CMB research in India faces challenges such as lack of funding, lack of infrastructure, and lack of trained manpower.

CMB research in India has opportunities such as collaboration with international teams, access to large datasets, and development of new technologies.

India can contribute to the global effort in CMB research by launching a satellite dedicated to CMB research, collaborating with international teams, and hosting international conferences.

CMB research has the potential to advance scientific knowledge, lead to technological development, and contribute to economic growth in India.

The government can promote CMB research in India by providing funding, developing infrastructure, and training manpower.

The private sector can promote CMB research in India by providing funding, developing technology, and collaborating with research institutions.
