The Upanishads, a collection of ancient Indian philosophical texts, contain the earliest known reference to black holes, describing them as regions of infinite density and gravity from which nothing can escape.

In Sanskrit, black holes are referred to as 'Kalapa', which literally translates to 'the devourer of time'.

Adi Shankara, an influential Indian philosopher, proposed the idea of a 'singularity' at the center of a black hole, where all matter is compressed to an infinitely small point.

In Indian philosophy, 'maya' refers to the illusion of the physical world. In the context of black holes, it suggests that the apparent reality of the black hole's event horizon and singularity may be an illusion.

According to Indian philosophy, 'karma' refers to the sum of one's actions and their consequences. In the context of black holes, it is believed that the mass of a black hole is determined by the collective karma of the beings that contribute to its formation.

Brahmagupta, an Indian astronomer and mathematician, proposed the idea of a 'black star' as a possible explanation for black holes. He suggested that these 'black stars' were so dense that they could not emit any light, making them invisible.

In Indian philosophy, 'nirvana' refers to the ultimate goal of spiritual liberation, where one transcends the cycle of birth, death, and rebirth. In the context of black holes, it suggests that the study of black holes can lead to a deeper understanding of the nature of reality and the ultimate liberation from the limitations of the physical world.

S. Chandrasekhar, an Indian-American astrophysicist, made significant contributions to the study of black holes and gravitational waves. He was awarded the Nobel Prize in Physics in 1983 for his work on the theory of white dwarf stars and his contributions to the study of black holes.

In Indian philosophy, 'brahman' refers to the ultimate reality of the universe, the underlying essence of all existence. In the context of black holes, it suggests that the study of black holes can lead to a deeper understanding of the nature of reality and the interconnectedness of all things.

In Indian philosophy, 'samsara' refers to the cycle of birth, death, and rebirth. In the context of black holes, it is believed that the singularity at the center of a black hole represents the point where the cycle of samsara begins and ends.

S.N. Bose, an Indian mathematician and physicist, developed a mathematical model for the gravitational field of a black hole. His work laid the foundation for the study of black hole physics and contributed to the development of general relativity.

In Indian philosophy, 'moksha' refers to the ultimate goal of spiritual liberation, where one transcends the cycle of birth, death, and rebirth. In the context of black holes, it suggests that the study of black holes can lead to a deeper understanding of the nature of reality and the ultimate liberation from the limitations of the physical world.

Jayant Narlikar, an Indian astrophysicist and cosmologist, proposed the idea of 'naked singularities' in the context of black holes. He suggested that under certain conditions, it is possible for a black hole to exist without an event horizon, revealing the singularity at its center.

In Indian philosophy, 'dharma' refers to the moral and ethical principles that govern the universe. In the context of black holes, it is believed that the singularity at the center of a black hole represents the point where all moral and ethical distinctions dissolve.

Abhas Mitra, an Indian astronomer and astrophysicist, proposed the idea of 'black holes as wormholes'. He suggested that black holes could potentially connect different regions of spacetime, acting as portals or shortcuts through the universe.
