Srinivasa Ramanujan is not a major mathematician of ancient India, while Aryabhata, Brahmagupta, and Bhaskara II are.

Lilavati is not a major work of Indian astronomy, while the Surya Siddhanta, Aryabhatiya, and Brahmagupta Siddhanta are.

Aryabhata, an Indian astronomer and mathematician, proposed a heliocentric model of the solar system in the 5th century CE, suggesting that the Earth and other planets revolve around the Sun.

Varahamihira, an Indian astronomer and astrologer, developed a system of classifying stars based on their brightness and color, which was later adopted by astronomers in other parts of the world.

None of the ancient Indian astronomers proposed a theory of the expansion of the universe. This concept was developed much later in the 20th century by modern astronomers.

Brahmagupta, an Indian astronomer and mathematician, developed a method for calculating the positions of celestial bodies using trigonometry, which was later adopted by astronomers in other parts of the world.

None of the ancient Indian astronomers developed a theory of planetary motion based on elliptical orbits. This concept was developed much later in the 17th century by Johannes Kepler.

Varahamihira, an Indian astronomer and astrologer, developed a system for predicting eclipses and other celestial events, which was used by astronomers for centuries.

Madhava of Sangamagrama is considered the founder of the Kerala school of astronomy and mathematics, which flourished in the 14th and 15th centuries.

Brahmagupta was an ancient Indian mathematician and astronomer who lived in the 6th century CE. He is credited with developing the concept of zero, which was a major breakthrough in mathematics.

Brahmagupta was an ancient Indian mathematician and astronomer who lived in the 6th century CE. He is credited with developing the concept of negative numbers.

Aryabhata was an ancient Indian mathematician and astronomer who lived in the 5th century CE. He is credited with developing the concept of the decimal system.

Aryabhata was an ancient Indian mathematician and astronomer who lived in the 5th century CE. He is credited with developing the concept of the sine function.

Bhaskara II was an ancient Indian mathematician and astronomer who lived in the 12th century CE. He is credited with developing the concept of the cosine function.
